Though yet of Hamlet our deere Brothers death +The memory be greene: and that it vs befitted +To beare our hearts in greefe, and our whole Kingdome +To be contracted in one brow of woe: +Yet so farre hath Discretion fought with Nature, +That we with wisest sorrow thinke on him, +Together with remembrance of our selues. +Therefore our sometimes Sister, now our Queene, +Th' imperiall Ioyntresse of this warlike State, +Haue we, as 'twere, with a defeated ioy, +With one Auspicious, and one Dropping eye, +With mirth in Funerall, and with Dirge in Marriage, +In equall Scale weighing Delight and Dole +Taken to Wife; nor haue we heerein barr'd +Your better Wisedomes, which haue freely gone +With this affaire along, for all our Thankes. +Now followes, that you know young Fortinbras, +Holding a weake supposall of our worth; +Or thinking by our late deere Brothers death, +Our State to be disioynt, and out of Frame, +Colleagued with the dreame of his Aduantage; +He hath not fayl'd to pester vs with Message, +Importing the surrender of those Lands +Lost by his Father: with all Bonds of Law +To our most valiant Brother. So much for him. +Enter Voltemand and Cornelius. + +Now for our selfe, and for this time of meeting +Thus much the businesse is. We haue heere writ +To Norway, Vncle of young Fortinbras, +Who Impotent and Bedrid, scarsely heares +Of this his Nephewes purpose, to suppresse +His further gate heerein. In that the Leuies, +The Lists, and full proportions are all made +Out of his subiect: and we heere dispatch +You good Cornelius, and you Voltemand, +For bearing of this greeting to old Norway, +Giuing to you no further personall power +To businesse with the King, more then the scope +Of these dilated Articles allow: +Farewell, and let your hast commend your duty + + Volt. In that, and all things, will we shew our duty + + King. We doubt it nothing, heartily farewell. + +Exit Voltemand and Cornelius. + +And now Laertes, what's the newes with you? +You told vs of some suite. What is't Laertes? +You cannot speake of Reason to the Dane, +And loose your voyce. What would'st thou beg Laertes, +That shall not be my Offer, not thy Asking? +The Head is not more Natiue to the Heart, +The Hand more instrumentall to the Mouth, +Then is the Throne of Denmarke to thy Father. +What would'st thou haue Laertes? + Laer. Dread my Lord, +Your leaue and fauour to returne to France, +From whence, though willingly I came to Denmarke +To shew my duty in your Coronation, +Yet now I must confesse, that duty done, +My thoughts and wishes bend againe towards France, +And bow them to your gracious leaue and pardon + + King. Haue you your Fathers leaue? +What sayes Pollonius? + Pol. He hath my Lord: +I do beseech you giue him leaue to go + + King. Take thy faire houre Laertes, time be thine, +And thy best graces spend it at thy will: +But now my Cosin Hamlet, and my Sonne? + Ham. A little more then kin, and lesse then kinde + + King. How is it that the Clouds still hang on you? + Ham. Not so my Lord, I am too much i'th' Sun + + Queen. Good Hamlet cast thy nightly colour off, +And let thine eye looke like a Friend on Denmarke. +Do not for euer with thy veyled lids +Seeke for thy Noble Father in the dust; +Thou know'st 'tis common, all that liues must dye, +Passing through Nature, to Eternity + + Ham. I Madam, it is common + + Queen. If it be; +Why seemes it so particular with thee + + Ham. Seemes Madam? Nay, it is: I know not Seemes: +'Tis not alone my Inky Cloake (good Mother) +Nor Customary suites of solemne Blacke, +Nor windy suspiration of forc'd breath, +No, nor the fruitfull Riuer in the Eye, +Nor the deiected hauiour of the Visage, +Together with all Formes, Moods, shewes of Griefe, +That can denote me truly. These indeed Seeme, +For they are actions that a man might play: +But I haue that Within, which passeth show; +These, but the Trappings, and the Suites of woe + + King. 'Tis sweet and commendable +In your Nature Hamlet, +To giue these mourning duties to your Father: +But you must know, your Father lost a Father, +That Father lost, lost his, and the Suruiuer bound +In filiall Obligation, for some terme +To do obsequious Sorrow. But to perseuer +In obstinate Condolement, is a course +Of impious stubbornnesse. 'Tis vnmanly greefe, +It shewes a will most incorrect to Heauen, +A Heart vnfortified, a Minde impatient, +An Vnderstanding simple, and vnschool'd: +For, what we know must be, and is as common +As any the most vulgar thing to sence, +Why should we in our peeuish Opposition +Take it to heart? Fye, 'tis a fault to Heauen, +A fault against the Dead, a fault to Nature, +To Reason most absurd, whose common Theame +Is death of Fathers, and who still hath cried, +From the first Coarse, till he that dyed to day, +This must be so. We pray you throw to earth +This vnpreuayling woe, and thinke of vs +As of a Father; For let the world take note, +You are the most immediate to our Throne, +And with no lesse Nobility of Loue, +Then that which deerest Father beares his Sonne, +Do I impart towards you. For your intent +In going backe to Schoole in Wittenberg, +It is most retrograde to our desire: +And we beseech you, bend you to remaine +Heere in the cheere and comfort of our eye, +Our cheefest Courtier Cosin, and our Sonne + + Qu. Let not thy Mother lose her Prayers Hamlet: +I prythee stay with vs, go not to Wittenberg + + Ham. I shall in all my best +Obey you Madam + + King. Why 'tis a louing, and a faire Reply, +Be as our selfe in Denmarke. Madam come, +This gentle and vnforc'd accord of Hamlet +Sits smiling to my heart; in grace whereof, +No iocond health that Denmarke drinkes to day, +But the great Cannon to the Clowds shall tell, +And the Kings Rouce, the Heauens shall bruite againe, +Respeaking earthly Thunder. Come away. + +Exeunt. + +Manet Hamlet. + + Ham. Oh that this too too solid Flesh, would melt, +Thaw, and resolue it selfe into a Dew: +Or that the Euerlasting had not fixt +His Cannon 'gainst Selfe-slaughter. O God, O God! +How weary, stale, flat, and vnprofitable +Seemes to me all the vses of this world? +Fie on't? Oh fie, fie, 'tis an vnweeded Garden +That growes to Seed: Things rank, and grosse in Nature +Possesse it meerely. That it should come to this: +But two months dead: Nay, not so much; not two, +So excellent a King, that was to this +Hiperion to a Satyre: so louing to my Mother, +That he might not beteene the windes of heauen +Visit her face too roughly. Heauen and Earth +Must I remember: why she would hang on him, +As if encrease of Appetite had growne +By what is fed on; and yet within a month? +Let me not thinke on't: Frailty, thy name is woman. +A little Month, or ere those shooes were old, +With which she followed my poore Fathers body +Like Niobe, all teares. Why she, euen she. +(O Heauen! A beast that wants discourse of Reason +Would haue mourn'd longer) married with mine Vnkle, +My Fathers Brother: but no more like my Father, +Then I to Hercules. Within a Moneth? +Ere yet the salt of most vnrighteous Teares +Had left the flushing of her gauled eyes, +She married. O most wicked speed, to post +With such dexterity to Incestuous sheets: +It is not, nor it cannot come to good. +But breake my heart, for I must hold my tongue. +Enter Horatio, Barnardo, and Marcellus. + + Hor. Haile to your Lordship + + Ham. I am glad to see you well: +Horatio, or I do forget my selfe + + Hor. The same my Lord, +And your poore Seruant euer + + Ham. Sir my good friend, +Ile change that name with you: +And what make you from Wittenberg Horatio? +Marcellus + + Mar. My good Lord + + Ham. I am very glad to see you: good euen Sir. +But what in faith make you from Wittemberge? + Hor. A truant disposition, good my Lord + + Ham. I would not haue your Enemy say so; +Nor shall you doe mine eare that violence, +To make it truster of your owne report +Against your selfe. I know you are no Truant: +But what is your affaire in Elsenour? +Wee'l teach you to drinke deepe, ere you depart + + Hor. My Lord, I came to see your Fathers Funerall + + Ham. I pray thee doe not mock me (fellow Student) +I thinke it was to see my Mothers Wedding + + Hor. Indeed my Lord, it followed hard vpon + + Ham. Thrift thrift Horatio: the Funerall Bakt-meats +Did coldly furnish forth the Marriage Tables; +Would I had met my dearest foe in heauen, +Ere I had euer seene that day Horatio. +My father, me thinkes I see my father + + Hor. Oh where my Lord? + Ham. In my minds eye (Horatio) + Hor. I saw him once; he was a goodly King + + Ham. He was a man, take him for all in all: +I shall not look vpon his like againe + + Hor. My Lord, I thinke I saw him yesternight + + Ham. Saw? Who? + Hor. My Lord, the King your Father + + Ham. The King my Father? + Hor. Season your admiration for a while +With an attent eare; till I may deliuer +Vpon the witnesse of these Gentlemen, +This maruell to you + + Ham. For Heauens loue let me heare + + Hor. Two nights together, had these Gentlemen +(Marcellus and Barnardo) on their Watch +In the dead wast and middle of the night +Beene thus encountred. A figure like your Father, +Arm'd at all points exactly, Cap a Pe, +Appeares before them, and with sollemne march +Goes slow and stately: By them thrice he walkt, +By their opprest and feare-surprized eyes, +Within his Truncheons length; whilst they bestil'd +Almost to Ielly with the Act of feare, +Stand dumbe and speake not to him. This to me +In dreadfull secrecie impart they did, +And I with them the third Night kept the Watch, +Whereas they had deliuer'd both in time, +Forme of the thing; each word made true and good, +The Apparition comes. I knew your Father: +These hands are not more like + + Ham. But where was this? + Mar. My Lord vpon the platforme where we watcht + + Ham. Did you not speake to it? + Hor. My Lord, I did; +But answere made it none: yet once me thought +It lifted vp it head, and did addresse +It selfe to motion, like as it would speake: +But euen then, the Morning Cocke crew lowd; +And at the sound it shrunke in hast away, +And vanisht from our sight + + Ham. Tis very strange + + Hor. As I doe liue my honourd Lord 'tis true; +And we did thinke it writ downe in our duty +To let you know of it + + Ham. Indeed, indeed Sirs; but this troubles me. +Hold you the watch to Night? + Both. We doe my Lord + + Ham. Arm'd, say you? + Both. Arm'd, my Lord + + Ham. From top to toe? + Both. My Lord, from head to foote + + Ham. Then saw you not his face? + Hor. O yes, my Lord, he wore his Beauer vp + + Ham. What, lookt he frowningly? + Hor. A countenance more in sorrow then in anger + + Ham. Pale, or red? + Hor. Nay very pale + + Ham. And fixt his eyes vpon you? + Hor. Most constantly + + Ham. I would I had beene there + + Hor. It would haue much amaz'd you + + Ham. Very like, very like: staid it long? + Hor. While one with moderate hast might tell a hundred + + All. Longer, longer + + Hor. Not when I saw't + + Ham. His Beard was grisly? no + + Hor. It was, as I haue seene it in his life, +A Sable Siluer'd + + Ham. Ile watch to Night; perchance 'twill wake againe + + Hor. I warrant you it will + + Ham. If it assume my noble Fathers person, +Ile speake to it, though Hell it selfe should gape +And bid me hold my peace. I pray you all, +If you haue hitherto conceald this sight; +Let it bee treble in your silence still: +And whatsoeuer els shall hap to night, +Giue it an vnderstanding but no tongue; +I will requite your loues; so fare ye well: +Vpon the Platforme twixt eleuen and twelue, +Ile visit you + + All. Our duty to your Honour. + +Exeunt + + Ham. Your loue, as mine to you: farewell. +My Fathers Spirit in Armes? All is not well: +I doubt some foule play: would the Night were come; +Till then sit still my soule; foule deeds will rise, +Though all the earth orewhelm them to mens eies. +Enter. + + +Scena Tertia + + +Enter Laertes and Ophelia. + + Laer. My necessaries are imbark't; Farewell: +And Sister, as the Winds giue Benefit, +And Conuoy is assistant; doe not sleepe, +But let me heare from you + + Ophel. Doe you doubt that? + Laer. For Hamlet, and the trifling of his fauours, +Hold it a fashion and a toy in Bloude; +A Violet in the youth of Primy Nature; +Froward, not permanent; sweet not lasting +The suppliance of a minute? No more + + Ophel. No more but so + + Laer. Thinke it no more: +For nature cressant does not grow alone, +In thewes and Bulke: but as his Temple waxes, +The inward seruice of the Minde and Soule +Growes wide withall. Perhaps he loues you now, +And now no soyle nor cautell doth besmerch +The vertue of his feare: but you must feare +His greatnesse weigh'd, his will is not his owne; +For hee himselfe is subiect to his Birth: +Hee may not, as vnuallued persons doe, +Carue for himselfe; for, on his choyce depends +The sanctity and health of the whole State. +And therefore must his choyce be circumscrib'd +Vnto the voyce and yeelding of that Body, +Whereof he is the Head. Then if he sayes he loues you, +It fits your wisedome so farre to beleeue it; +As he in his peculiar Sect and force +May giue his saying deed: which is no further, +Then the maine voyce of Denmarke goes withall. +Then weight what losse your Honour may sustaine, +If with too credent eare you list his Songs; +Or lose your Heart; or your chast Treasure open +To his vnmastred importunity. +Feare it Ophelia, feare it my deare Sister, +And keepe within the reare of your Affection; +Out of the shot and danger of Desire. +The chariest Maid is Prodigall enough, +If she vnmaske her beauty to the Moone: +Vertue it selfe scapes not calumnious stroakes, +The Canker Galls, the Infants of the Spring +Too oft before the buttons be disclos'd, +And in the Morne and liquid dew of Youth, +Contagious blastments are most imminent. +Be wary then, best safety lies in feare; +Youth to it selfe rebels, though none else neere + + Ophe. I shall th' effect of this good Lesson keepe, +As watchmen to my heart: but good my Brother +Doe not as some vngracious Pastors doe, +Shew me the steepe and thorny way to Heauen; +Whilst like a puft and recklesse Libertine +Himselfe, the Primrose path of dalliance treads, +And reaks not his owne reade + + Laer. Oh, feare me not. +Enter Polonius. + +I stay too long; but here my Father comes: +A double blessing is a double grace; +Occasion smiles vpon a second leaue + + Polon. Yet heere Laertes? Aboord, aboord for shame, +The winde sits in the shoulder of your saile, +And you are staid for there: my blessing with you; +And these few Precepts in thy memory, +See thou Character. Giue thy thoughts no tongue, +Nor any vnproportion'd thoughts his Act: +Be thou familiar; but by no meanes vulgar: +The friends thou hast, and their adoption tride, +Grapple them to thy Soule, with hoopes of Steele: +But doe not dull thy palme, with entertainment +Of each vnhatch't, vnfledg'd Comrade. Beware +Of entrance to a quarrell: but being in +Bear't that th' opposed may beware of thee. +Giue euery man thine eare; but few thy voyce: +Take each mans censure; but reserue thy iudgement: +Costly thy habit as thy purse can buy; +But not exprest in fancie; rich, not gawdie: +For the Apparell oft proclaimes the man. +And they in France of the best ranck and station, +Are of a most select and generous cheff in that. +Neither a borrower, nor a lender be; +For lone oft loses both it selfe and friend: +And borrowing duls the edge of Husbandry. +This aboue all; to thine owne selfe be true: +And it must follow, as the Night the Day, +Thou canst not then be false to any man. +Farewell: my Blessing season this in thee + + Laer. Most humbly doe I take my leaue, my Lord + + Polon. The time inuites you, goe, your seruants tend + + Laer. Farewell Ophelia, and remember well +What I haue said to you + + Ophe. Tis in my memory lockt, +And you your selfe shall keepe the key of it + + Laer. Farewell. + +Exit Laer. + + Polon. What ist Ophelia he hath said to you? + Ophe. So please you, somthing touching the L[ord]. Hamlet + + Polon. Marry, well bethought: +Tis told me he hath very oft of late +Giuen priuate time to you; and you your selfe +Haue of your audience beene most free and bounteous. +If it be so, as so tis put on me; +And that in way of caution: I must tell you, +You doe not vnderstand your selfe so cleerely, +As it behoues my Daughter, and your Honour. +What is betweene you, giue me vp the truth? + Ophe. He hath my Lord of late, made many tenders +Of his affection to me + + Polon. Affection, puh. You speake like a greene Girle, +Vnsifted in such perillous Circumstance. +Doe you beleeue his tenders, as you call them? + Ophe. I do not know, my Lord, what I should thinke + + Polon. Marry Ile teach you; thinke your selfe a Baby, +That you haue tane his tenders for true pay, +Which are not starling. Tender your selfe more dearly; +Or not to crack the winde of the poore Phrase, +Roaming it thus, you'l tender me a foole + + Ophe. My Lord, he hath importun'd me with loue, +In honourable fashion + + Polon. I, fashion you may call it, go too, go too + + Ophe. And hath giuen countenance to his speech, +My Lord, with all the vowes of Heauen + + Polon. I, Springes to catch Woodcocks. I doe know +When the Bloud burnes, how Prodigall the Soule +Giues the tongue vowes: these blazes, Daughter, +Giuing more light then heate; extinct in both, +Euen in their promise, as it is a making; +You must not take for fire. For this time Daughter, +Be somewhat scanter of your Maiden presence; +Set your entreatments at a higher rate, +Then a command to parley. For Lord Hamlet, +Beleeue so much in him, that he is young, +And with a larger tether may he walke, +Then may be giuen you. In few, Ophelia, +Doe not beleeue his vowes; for they are Broakers, +Not of the eye, which their Inuestments show: +But meere implorators of vnholy Sutes, +Breathing like sanctified and pious bonds, +The better to beguile. This is for all: +I would not, in plaine tearmes, from this time forth, +Haue you so slander any moment leisure, +As to giue words or talke with the Lord Hamlet: +Looke too't, I charge you; come your wayes + + Ophe. I shall obey my Lord. + +Exeunt. + +Enter Hamlet, Horatio, Marcellus. + + Ham. The Ayre bites shrewdly: is it very cold? + Hor. It is a nipping and an eager ayre + + Ham. What hower now? + Hor. I thinke it lacks of twelue + + Mar. No, it is strooke + + Hor. Indeed I heard it not: then it drawes neere the season, +Wherein the Spirit held his wont to walke. +What does this meane my Lord? + Ham. The King doth wake to night, and takes his rouse, +Keepes wassels and the swaggering vpspring reeles, +And as he dreines his draughts of Renish downe, +The kettle Drum and Trumpet thus bray out +The triumph of his Pledge + + Horat. Is it a custome? + Ham. I marry ist; +And to my mind, though I am natiue heere, +And to the manner borne: It is a Custome +More honour'd in the breach, then the obseruance. +Enter Ghost. + + Hor. Looke my Lord, it comes + + Ham. Angels and Ministers of Grace defend vs: +Be thou a Spirit of health, or Goblin damn'd, +Bring with thee ayres from Heauen, or blasts from Hell, +Be thy euents wicked or charitable, +Thou com'st in such a questionable shape +That I will speake to thee. Ile call thee Hamlet, +King, Father, Royall Dane: Oh, oh, answer me, +Let me not burst in Ignorance; but tell +Why thy Canoniz'd bones Hearsed in death, +Haue burst their cerments, why the Sepulcher +Wherein we saw thee quietly enurn'd, +Hath op'd his ponderous and Marble iawes, +To cast thee vp againe? What may this meane? +That thou dead Coarse againe in compleat steele, +Reuisits thus the glimpses of the Moone, +Making Night hidious? And we fooles of Nature, +So horridly to shake our disposition, +With thoughts beyond thee; reaches of our Soules, +Say, why is this? wherefore? what should we doe? + +Ghost beckens Hamlet. + + Hor. It beckons you to goe away with it, +As if it some impartment did desire +To you alone + + Mar. Looke with what courteous action +It wafts you to a more remoued ground: +But doe not goe with it + + Hor. No, by no meanes + + Ham. It will not speake: then will I follow it + + Hor. Doe not my Lord + + Ham. Why, what should be the feare? +I doe not set my life at a pins fee; +And for my Soule, what can it doe to that? +Being a thing immortall as it selfe: +It waues me forth againe; Ile follow it + + Hor. What if it tempt you toward the Floud my Lord? +Or to the dreadfull Sonnet of the Cliffe, +That beetles o're his base into the Sea, +And there assumes some other horrible forme, +Which might depriue your Soueraignty of Reason, +And draw you into madnesse thinke of it? + Ham. It wafts me still: goe on, Ile follow thee + + Mar. You shall not goe my Lord + + Ham. Hold off your hand + + Hor. Be rul'd, you shall not goe + + Ham. My fate cries out, +And makes each petty Artire in this body, +As hardy as the Nemian Lions nerue: +Still am I cal'd? Vnhand me Gentlemen: +By Heau'n, Ile make a Ghost of him that lets me: +I say away, goe on, Ile follow thee. + +Exeunt. Ghost & Hamlet. + + Hor. He waxes desperate with imagination + + Mar. Let's follow; 'tis not fit thus to obey him + + Hor. Haue after, to what issue will this come? + Mar. Something is rotten in the State of Denmarke + + Hor. Heauen will direct it + + Mar. Nay, let's follow him. + +Exeunt. + +Enter Ghost and Hamlet. + + Ham. Where wilt thou lead me? speak; Ile go no further + + Gho. Marke me + + Ham. I will + + Gho. My hower is almost come, +When I to sulphurous and tormenting Flames +Must render vp my selfe + + Ham. Alas poore Ghost + + Gho. Pitty me not, but lend thy serious hearing +To what I shall vnfold + + Ham. Speake, I am bound to heare + + Gho. So art thou to reuenge, when thou shalt heare + + Ham. What? + Gho. I am thy Fathers Spirit, +Doom'd for a certaine terme to walke the night; +And for the day confin'd to fast in Fiers, +Till the foule crimes done in my dayes of Nature +Are burnt and purg'd away? But that I am forbid +To tell the secrets of my Prison-House; +I could a Tale vnfold, whose lightest word +Would harrow vp thy soule, freeze thy young blood, +Make thy two eyes like Starres, start from their Spheres, +Thy knotty and combined lockes to part, +And each particular haire to stand an end, +Like Quilles vpon the fretfull Porpentine: +But this eternall blason must not be +To eares of flesh and bloud; list Hamlet, oh list, +If thou didst euer thy deare Father loue + + Ham. Oh Heauen! + Gho. Reuenge his foule and most vnnaturall Murther + + Ham. Murther? + Ghost. Murther most foule, as in the best it is; +But this most foule, strange, and vnnaturall + + Ham. Hast, hast me to know it, +That with wings as swift +As meditation, or the thoughts of Loue, +May sweepe to my Reuenge + + Ghost. I finde thee apt, +And duller should'st thou be then the fat weede +That rots it selfe in ease, on Lethe Wharfe, +Would'st thou not stirre in this. Now Hamlet heare: +It's giuen out, that sleeping in mine Orchard, +A Serpent stung me: so the whole eare of Denmarke, +Is by a forged processe of my death +Rankly abus'd: But know thou Noble youth, +The Serpent that did sting thy Fathers life, +Now weares his Crowne + + Ham. O my Propheticke soule: mine Vncle? + Ghost. I that incestuous, that adulterate Beast +With witchcraft of his wits, hath Traitorous guifts. +Oh wicked Wit, and Gifts, that haue the power +So to seduce? Won to this shamefull Lust +The will of my most seeming vertuous Queene: +Oh Hamlet, what a falling off was there, +From me, whose loue was of that dignity, +That it went hand in hand, euen with the Vow +I made to her in Marriage; and to decline +Vpon a wretch, whose Naturall gifts were poore +To those of mine. But Vertue, as it neuer wil be moued, +Though Lewdnesse court it in a shape of Heauen: +So Lust, though to a radiant Angell link'd, +Will sate it selfe in a Celestiall bed, & prey on Garbage. +But soft, me thinkes I sent the Mornings Ayre; +Briefe let me be: Sleeping within mine Orchard, +My custome alwayes in the afternoone; +Vpon my secure hower thy Vncle stole +With iuyce of cursed Hebenon in a Violl, +And in the Porches of mine eares did poure +The leaperous Distilment; whose effect +Holds such an enmity with bloud of Man, +That swift as Quick-siluer, it courses through +The naturall Gates and Allies of the body; +And with a sodaine vigour it doth posset +And curd, like Aygre droppings into Milke, +The thin and wholsome blood: so did it mine; +And a most instant Tetter bak'd about, +Most Lazar-like, with vile and loathsome crust, +All my smooth Body. +Thus was I, sleeping, by a Brothers hand, +Of Life, of Crowne, and Queene at once dispatcht; +Cut off euen in the Blossomes of my Sinne, +Vnhouzzled, disappointed, vnnaneld, +No reckoning made, but sent to my account +With all my imperfections on my head; +Oh horrible Oh horrible, most horrible: +If thou hast nature in thee beare it not; +Let not the Royall Bed of Denmarke be +A Couch for Luxury and damned Incest. +But howsoeuer thou pursuest this Act, +Taint not thy mind; nor let thy Soule contriue +Against thy Mother ought; leaue her to heauen, +And to those Thornes that in her bosome lodge, +To pricke and sting her. Fare thee well at once; +The Glow-worme showes the Matine to be neere, +And gins to pale his vneffectuall Fire: +Adue, adue, Hamlet: remember me. +Enter. + + Ham. Oh all you host of Heauen! Oh Earth; what els? +And shall I couple Hell? Oh fie: hold my heart; +And you my sinnewes, grow not instant Old; +But beare me stiffely vp: Remember thee? +I, thou poore Ghost, while memory holds a seate +In this distracted Globe: Remember thee? +Yea, from the Table of my Memory, +Ile wipe away all triuiall fond Records, +All sawes of Bookes, all formes, all presures past, +That youth and obseruation coppied there; +And thy Commandment all alone shall liue +Within the Booke and Volume of my Braine, +Vnmixt with baser matter; yes yes, by Heauen: +Oh most pernicious woman! +Oh Villaine, Villaine, smiling damned Villaine! +My Tables, my Tables; meet it is I set it downe, +That one may smile, and smile and be a Villaine; +At least I'm sure it may be so in Denmarke; +So Vnckle there you are: now to my word; +It is; Adue, Adue, Remember me: I haue sworn't + + Hor. & Mar. within. My Lord, my Lord. +Enter Horatio and Marcellus. + + Mar. Lord Hamlet + + Hor. Heauen secure him + + Mar. So be it + + Hor. Illo, ho, ho, my Lord + + Ham. Hillo, ho, ho, boy; come bird, come + + Mar. How ist my Noble Lord? + Hor. What newes, my Lord? + Ham. Oh wonderfull! + Hor. Good my Lord tell it + + Ham. No you'l reueale it + + Hor. Not I, my Lord, by Heauen + + Mar. Nor I, my Lord + + Ham. How say you then, would heart of man once think it? +But you'l be secret? + Both. I, by Heau'n, my Lord + + Ham. There's nere a villaine dwelling in all Denmarke +But hee's an arrant knaue + + Hor. There needs no Ghost my Lord, come from the +Graue, to tell vs this + + Ham. Why right, you are i'th' right; +And so, without more circumstance at all, +I hold it fit that we shake hands, and part: +You, as your busines and desires shall point you: +For euery man ha's businesse and desire, +Such as it is: and for mine owne poore part, +Looke you, Ile goe pray + + Hor. These are but wild and hurling words, my Lord + + Ham. I'm sorry they offend you heartily: +Yes faith, heartily + + Hor. There's no offence my Lord + + Ham. Yes, by Saint Patricke, but there is my Lord, +And much offence too, touching this Vision heere: +It is an honest Ghost, that let me tell you: +For your desire to know what is betweene vs, +O'remaster't as you may. And now good friends, +As you are Friends, Schollers and Soldiers, +Giue me one poore request + + Hor. What is't my Lord? we will + + Ham. Neuer make known what you haue seen to night + + Both. My Lord, we will not + + Ham. Nay, but swear't + + Hor. Infaith my Lord, not I + + Mar. Nor I my Lord: in faith + + Ham. Vpon my sword + + Marcell. We haue sworne my Lord already + + Ham. Indeed, vpon my sword, Indeed + + Gho. Sweare. + +Ghost cries vnder the Stage. + + Ham. Ah ha boy, sayest thou so. Art thou there truepenny? +Come one you here this fellow in the selleredge +Consent to sweare + + Hor. Propose the Oath my Lord + + Ham. Neuer to speake of this that you haue seene. +Sweare by my sword + + Gho. Sweare + + Ham. Hic & vbique? Then wee'l shift for grownd, +Come hither Gentlemen, +And lay your hands againe vpon my sword, +Neuer to speake of this that you haue heard: +Sweare by my Sword + + Gho. Sweare + + Ham. Well said old Mole, can'st worke i'th' ground so fast? +A worthy Pioner, once more remoue good friends + + Hor. Oh day and night: but this is wondrous strange + + Ham. And therefore as a stranger giue it welcome. +There are more things in Heauen and Earth, Horatio, +Then are dream't of in our Philosophy. But come, +Here as before, neuer so helpe you mercy, +How strange or odde so ere I beare my selfe; +(As I perchance heereafter shall thinke meet +To put an Anticke disposition on:) +That you at such time seeing me, neuer shall +With Armes encombred thus, or thus, head shake; +Or by pronouncing of some doubtfull Phrase; +As well, we know, or we could and if we would, +Or if we list to speake; or there be and if there might, +Or such ambiguous giuing out to note, +That you know ought of me; this not to doe: +So grace and mercy at your most neede helpe you: +Sweare + + Ghost. Sweare + + Ham. Rest, rest perturbed Spirit: so Gentlemen, +With all my loue I doe commend me to you; +And what so poore a man as Hamlet is, +May doe t' expresse his loue and friending to you, +God willing shall not lacke: let vs goe in together, +And still your fingers on your lippes I pray, +The time is out of ioynt: Oh cursed spight, +That euer I was borne to set it right. +Nay, come let's goe together. + +Exeunt. + + +Actus Secundus. + +Enter Polonius, and Reynoldo. + + Polon. Giue him his money, and these notes Reynoldo + + Reynol. I will my Lord + + Polon. You shall doe maruels wisely: good Reynoldo, +Before you visite him you make inquiry +Of his behauiour + + Reynol. My Lord, I did intend it + + Polon. Marry, well said; +Very well said. Looke you Sir, +Enquire me first what Danskers are in Paris; +And how, and who; what meanes; and where they keepe: +What company, at what expence: and finding +By this encompassement and drift of question, +That they doe know my sonne: Come you more neerer +Then your particular demands will touch it, +Take you as 'twere some distant knowledge of him, +And thus I know his father and his friends, +And in part him. Doe you marke this Reynoldo? + Reynol. I, very well my Lord + + Polon. And in part him, but you may say not well; +But if't be hee I meane, hees very wilde; +Addicted so and so; and there put on him +What forgeries you please; marry, none so ranke, +As may dishonour him; take heed of that: +But Sir, such wanton, wild, and vsuall slips, +As are Companions noted and most knowne +To youth and liberty + + Reynol. As gaming my Lord + + Polon. I, or drinking, fencing, swearing, +Quarelling, drabbing. You may goe so farre + + Reynol. My Lord that would dishonour him + + Polon. Faith no, as you may season it in the charge; +You must not put another scandall on him, +That hee is open to Incontinencie; +That's not my meaning: but breath his faults so quaintly, +That they may seeme the taints of liberty; +The flash and out-breake of a fiery minde, +A sauagenes in vnreclaim'd bloud of generall assault + + Reynol. But my good Lord + + Polon. Wherefore should you doe this? + Reynol. I my Lord, I would know that + + Polon. Marry Sir, heere's my drift, +And I belieue it is a fetch of warrant: +You laying these slight sulleyes on my Sonne, +As 'twere a thing a little soil'd i'th' working: +Marke you your party in conuerse; him you would sound, +Hauing euer seene. In the prenominate crimes, +The youth you breath of guilty, be assur'd +He closes with you in this consequence: +Good sir, or so, or friend, or Gentleman. +According to the Phrase and the Addition, +Of man and Country + + Reynol. Very good my Lord + + Polon. And then Sir does he this? +He does: what was I about to say? +I was about say somthing: where did I leaue? + Reynol. At closes in the consequence: +At friend, or so, and Gentleman + + Polon. At closes in the consequence, I marry, +He closes with you thus. I know the Gentleman, +I saw him yesterday, or tother day; +Or then or then, with such and such; and as you say, +There was he gaming, there o'retooke in's Rouse, +There falling out at Tennis; or perchance, +I saw him enter such a house of saile; +Videlicet, a Brothell, or so forth. See you now; +Your bait of falshood, takes this Cape of truth; +And thus doe we of wisedome and of reach +With windlesses, and with assaies of Bias, +By indirections finde directions out: +So by my former Lecture and aduice +Shall you my Sonne; you haue me, haue you not? + Reynol. My Lord I haue + + Polon. God buy you; fare you well + + Reynol. Good my Lord + + Polon. Obserue his inclination in your selfe + + Reynol. I shall my Lord + + Polon. And let him plye his Musicke + + Reynol. Well, my Lord. +Enter. + +Enter Ophelia. + + Polon. Farewell: +How now Ophelia, what's the matter? + Ophe. Alas my Lord, I haue beene so affrighted + + Polon. With what, in the name of Heauen? + Ophe. My Lord, as I was sowing in my Chamber, +Lord Hamlet with his doublet all vnbrac'd, +No hat vpon his head, his stockings foul'd, +Vngartred, and downe giued to his Anckle, +Pale as his shirt, his knees knocking each other, +And with a looke so pitious in purport, +As if he had been loosed out of hell, +To speake of horrors: he comes before me + + Polon. Mad for thy Loue? + Ophe. My Lord, I doe not know: but truly I do feare it + + Polon. What said he? + Ophe. He tooke me by the wrist, and held me hard; +Then goes he to the length of all his arme; +And with his other hand thus o're his brow, +He fals to such perusall of my face, +As he would draw it. Long staid he so, +At last, a little shaking of mine Arme: +And thrice his head thus wauing vp and downe; +He rais'd a sigh, so pittious and profound, +That it did seeme to shatter all his bulke, +And end his being. That done, he lets me goe, +And with his head ouer his shoulders turn'd, +He seem'd to finde his way without his eyes, +For out adores he went without their helpe; +And to the last, bended their light on me + + Polon. Goe with me, I will goe seeke the King, +This is the very extasie of Loue, +Whose violent property foredoes it selfe, +And leads the will to desperate Vndertakings, +As oft as any passion vnder Heauen, +That does afflict our Natures. I am sorrie, +What haue you giuen him any hard words of late? + Ophe. No my good Lord: but as you did command, +I did repell his Letters, and deny'de +His accesse to me + + Pol. That hath made him mad. +I am sorrie that with better speed and iudgement +I had not quoted him. I feare he did but trifle, +And meant to wracke thee: but beshrew my iealousie: +It seemes it is as proper to our Age, +To cast beyond our selues in our Opinions, +As it is common for the yonger sort +To lacke discretion. Come, go we to the King, +This must be knowne, being kept close might moue +More greefe to hide, then hate to vtter loue. + +Exeunt. + + +Scena Secunda. + +Enter King, Queene, Rosincrane, and Guildensterne Cum alijs. + + King. Welcome deere Rosincrance and Guildensterne. +Moreouer, that we much did long to see you, +The neede we haue to vse you, did prouoke +Our hastie sending. Something haue you heard +Of Hamlets transformation: so I call it, +Since not th' exterior, nor the inward man +Resembles that it was. What it should bee +More then his Fathers death, that thus hath put him +So much from th' vnderstanding of himselfe, +I cannot deeme of. I intreat you both, +That being of so young dayes brought vp with him: +And since so Neighbour'd to his youth, and humour, +That you vouchsafe your rest heere in our Court +Some little time: so by your Companies +To draw him on to pleasures, and to gather +So much as from Occasions you may gleane, +That open'd lies within our remedie + + Qu. Good Gentlemen, he hath much talk'd of you, +And sure I am, two men there are not liuing, +To whom he more adheres. If it will please you +To shew vs so much Gentrie, and good will, +As to expend your time with vs a-while, +For the supply and profit of our Hope, +Your Visitation shall receiue such thankes +As fits a Kings remembrance + + Rosin. Both your Maiesties +Might by the Soueraigne power you haue of vs, +Put your dread pleasures, more into Command +Then to Entreatie + + Guil. We both obey, +And here giue vp our selues, in the full bent, +To lay our Seruices freely at your feete, +To be commanded + + King. Thankes Rosincrance, and gentle Guildensterne + + Qu. Thankes Guildensterne and gentle Rosincrance. +And I beseech you instantly to visit +My too much changed Sonne. +Go some of ye, +And bring the Gentlemen where Hamlet is + + Guil. Heauens make our presence and our practises +Pleasant and helpfull to him. +Enter. + + Queene. Amen. +Enter Polonius. + + Pol. Th' Ambassadors from Norwey, my good Lord, +Are ioyfully return'd + + King. Thou still hast bin the father of good Newes + + Pol. Haue I, my Lord? Assure you, my good Liege, +I hold my dutie, as I hold my Soule, +Both to my God, one to my gracious King: +And I do thinke, or else this braine of mine +Hunts not the traile of Policie, so sure +As I haue vs'd to do: that I haue found +The very cause of Hamlets Lunacie + + King. Oh speake of that, that I do long to heare + + Pol. Giue first admittance to th' Ambassadors, +My Newes shall be the Newes to that great Feast + + King. Thy selfe do grace to them, and bring them in. +He tels me my sweet Queene, that he hath found +The head and sourse of all your Sonnes distemper + + Qu. I doubt it is no other, but the maine, +His Fathers death, and our o're-hasty Marriage. +Enter Polonius, Voltumand, and Cornelius. + + King. Well, we shall sift him. Welcome good Frends: +Say Voltumand, what from our Brother Norwey? + Volt. Most faire returne of Greetings, and Desires. +Vpon our first, he sent out to suppresse +His Nephewes Leuies, which to him appear'd +To be a preparation 'gainst the Poleak: +But better look'd into, he truly found +It was against your Highnesse, whereat greeued, +That so his Sicknesse, Age, and Impotence +Was falsely borne in hand, sends out Arrests +On Fortinbras, which he (in breefe) obeyes, +Receiues rebuke from Norwey: and in fine, +Makes Vow before his Vnkle, neuer more +To giue th' assay of Armes against your Maiestie. +Whereon old Norwey, ouercome with ioy, +Giues him three thousand Crownes in Annuall Fee, +And his Commission to imploy those Soldiers +So leuied as before, against the Poleak: +With an intreaty heerein further shewne, +That it might please you to giue quiet passe +Through your Dominions, for his Enterprize, +On such regards of safety and allowance, +As therein are set downe + + King. It likes vs well: +And at our more consider'd time wee'l read, +Answer, and thinke vpon this Businesse. +Meane time we thanke you, for your well-tooke Labour. +Go to your rest, at night wee'l Feast together. +Most welcome home. + +Exit Ambass. + + Pol. This businesse is very well ended. +My Liege, and Madam, to expostulate +What Maiestie should be, what Dutie is, +Why day is day; night, night; and time is time, +Were nothing but to waste Night, Day, and Time. +Therefore, since Breuitie is the Soule of Wit, +And tediousnesse, the limbes and outward flourishes, +I will be breefe. Your Noble Sonne is mad: +Mad call I it; for to define true Madnesse, +What is't, but to be nothing else but mad. +But let that go + + Qu. More matter, with lesse Art + + Pol. Madam, I sweare I vse no Art at all: +That he is mad, 'tis true: 'Tis true 'tis pittie, +And pittie it is true: A foolish figure, +But farewell it: for I will vse no Art. +Mad let vs grant him then: and now remaines +That we finde out the cause of this effect, +Or rather say, the cause of this defect; +For this effect defectiue, comes by cause, +Thus it remaines, and the remainder thus. Perpend, +I haue a daughter: haue, whil'st she is mine, +Who in her Dutie and Obedience, marke, +Hath giuen me this: now gather, and surmise. + +The Letter. + +To the Celestiall, and my Soules Idoll, the most beautifed Ophelia. +That's an ill Phrase, a vilde Phrase, beautified is a vilde +Phrase: but you shall heare these in her excellent white +bosome, these + + Qu. Came this from Hamlet to her + + Pol. Good Madam stay awhile, I will be faithfull. +Doubt thou, the Starres are fire, +Doubt, that the Sunne doth moue: +Doubt Truth to be a Lier, +But neuer Doubt, I loue. +O deere Ophelia, I am ill at these Numbers: I haue not Art to +reckon my grones; but that I loue thee best, oh most Best beleeue +it. Adieu. +Thine euermore most deere Lady, whilst this +Machine is to him, Hamlet. +This in Obedience hath my daughter shew'd me: +And more aboue hath his soliciting, +As they fell out by Time, by Meanes, and Place, +All giuen to mine eare + + King. But how hath she receiu'd his Loue? + Pol. What do you thinke of me? + King. As of a man, faithfull and Honourable + + Pol. I wold faine proue so. But what might you think? +When I had seene this hot loue on the wing, +As I perceiued it, I must tell you that +Before my Daughter told me what might you +Or my deere Maiestie your Queene heere, think, +If I had playd the Deske or Table-booke, +Or giuen my heart a winking, mute and dumbe, +Or look'd vpon this Loue, with idle sight, +What might you thinke? No, I went round to worke, +And (my yong Mistris) thus I did bespeake +Lord Hamlet is a Prince out of thy Starre, +This must not be: and then, I Precepts gaue her, +That she should locke her selfe from his Resort, +Admit no Messengers, receiue no Tokens: +Which done, she tooke the Fruites of my Aduice, +And he repulsed. A short Tale to make, +Fell into a Sadnesse, then into a Fast, +Thence to a Watch, thence into a Weaknesse, +Thence to a Lightnesse, and by this declension +Into the Madnesse whereon now he raues, +And all we waile for + + King. Do you thinke 'tis this? + Qu. It may be very likely + + Pol. Hath there bene such a time, I'de fain know that, +That I haue possitiuely said, 'tis so, +When it prou'd otherwise? + King. Not that I know + + Pol. Take this from this; if this be otherwise, +If Circumstances leade me, I will finde +Where truth is hid, though it were hid indeede +Within the Center + + King. How may we try it further? + Pol. You know sometimes +He walkes foure houres together, heere +In the Lobby + + Qu. So he ha's indeed + + Pol. At such a time Ile loose my Daughter to him, +Be you and I behinde an Arras then, +Marke the encounter: If he loue her not, +And be not from his reason falne thereon; +Let me be no Assistant for a State, +And keepe a Farme and Carters + + King. We will try it. +Enter Hamlet reading on a Booke. + + Qu. But looke where sadly the poore wretch +Comes reading + + Pol. Away I do beseech you, both away, +Ile boord him presently. + +Exit King & Queen. + +Oh giue me leaue. How does my good Lord Hamlet? + Ham. Well, God-a-mercy + + Pol. Do you know me, my Lord? + Ham. Excellent, excellent well: y'are a Fishmonger + + Pol. Not I my Lord + + Ham. Then I would you were so honest a man + + Pol. Honest, my Lord? + Ham. I sir, to be honest as this world goes, is to bee +one man pick'd out of two thousand + + Pol. That's very true, my Lord + + Ham. For if the Sun breed Magots in a dead dogge, +being a good kissing Carrion- +Haue you a daughter? + Pol. I haue my Lord + + Ham. Let her not walke i'thSunne: Conception is a +blessing, but not as your daughter may conceiue. Friend +looke too't + + Pol. How say you by that? Still harping on my daughter: +yet he knew me not at first; he said I was a Fishmonger: +he is farre gone, farre gone: and truly in my youth, +I suffred much extreamity for loue: very neere this. Ile +speake to him againe. What do you read my Lord? + Ham. Words, words, words + + Pol. What is the matter, my Lord? + Ham. Betweene who? + Pol. I meane the matter you meane, my Lord + + Ham. Slanders Sir: for the Satyricall slaue saies here, +that old men haue gray Beards; that their faces are wrinkled; +their eyes purging thicke Amber, or Plum-Tree +Gumme: and that they haue a plentifull locke of Wit, +together with weake Hammes. All which Sir, though I +most powerfully, and potently beleeue; yet I holde it +not Honestie to haue it thus set downe: For you your +selfe Sir, should be old as I am, if like a Crab you could +go backward + + Pol. Though this be madnesse, +Yet there is Method in't: will you walke +Out of the ayre my Lord? + Ham. Into my Graue? + Pol. Indeed that is out o'th' Ayre: +How pregnant (sometimes) his Replies are? +A happinesse, +That often Madnesse hits on, +Which Reason and Sanitie could not +So prosperously be deliuer'd of. +I will leaue him, +And sodainely contriue the meanes of meeting +Betweene him, and my daughter. +My Honourable Lord, I will most humbly +Take my leaue of you + + Ham. You cannot Sir take from me any thing, that I +will more willingly part withall, except my life, my +life + + Polon. Fare you well my Lord + + Ham. These tedious old fooles + + Polon. You goe to seeke my Lord Hamlet; there +hee is. +Enter Rosincran and Guildensterne. + + Rosin. God saue you Sir + + Guild. Mine honour'd Lord? + Rosin. My most deare Lord? + Ham. My excellent good friends? How do'st thou +Guildensterne? Oh, Rosincrane; good Lads: How doe ye +both? + Rosin. As the indifferent Children of the earth + + Guild. Happy, in that we are not ouer-happy: on Fortunes +Cap, we are not the very Button + + Ham. Nor the Soales of her Shoo? + Rosin. Neither my Lord + + Ham. Then you liue about her waste, or in the middle +of her fauour? + Guil. Faith, her priuates, we + + Ham. In the secret parts of Fortune? Oh, most true: +she is a Strumpet. What's the newes? + Rosin. None my Lord; but that the World's growne +honest + + Ham. Then is Doomesday neere: But your newes is +not true. Let me question more in particular: what haue +you my good friends, deserued at the hands of Fortune, +that she sends you to Prison hither? + Guil. Prison, my Lord? + Ham. Denmark's a Prison + + Rosin. Then is the World one + + Ham. A goodly one, in which there are many Confines, +Wards, and Dungeons; Denmarke being one o'th' +worst + + Rosin. We thinke not so my Lord + + Ham. Why then 'tis none to you; for there is nothing +either good or bad, but thinking makes it so: to me it is +a prison + + Rosin. Why then your Ambition makes it one: 'tis +too narrow for your minde + + Ham. O God, I could be bounded in a nutshell, and +count my selfe a King of infinite space; were it not that +I haue bad dreames + + Guil. Which dreames indeed are Ambition: for the +very substance of the Ambitious, is meerely the shadow +of a Dreame + + Ham. A dreame it selfe is but a shadow + + Rosin. Truely, and I hold Ambition of so ayry and +light a quality, that it is but a shadowes shadow + + Ham. Then are our Beggers bodies; and our Monarchs +and out-stretcht Heroes the Beggers Shadowes: +shall wee to th' Court: for, by my fey I cannot reason? + Both. Wee'l wait vpon you + + Ham. No such matter. I will not sort you with the +rest of my seruants: for to speake to you like an honest +man: I am most dreadfully attended; but in the beaten +way of friendship, What make you at Elsonower? + Rosin. To visit you my Lord, no other occasion + + Ham. Begger that I am, I am euen poore in thankes; +but I thanke you: and sure deare friends my thanks +are too deare a halfepeny; were you not sent for? Is it +your owne inclining? Is it a free visitation? Come, +deale iustly with me: come, come; nay speake + + Guil. What should we say my Lord? + Ham. Why any thing. But to the purpose; you were +sent for; and there is a kinde confession in your lookes; +which your modesties haue not craft enough to color, +I know the good King & Queene haue sent for you + + Rosin. To what end my Lord? + Ham. That you must teach me: but let mee coniure +you by the rights of our fellowship, by the consonancy of +our youth, by the Obligation of our euer-preserued loue, +and by what more deare, a better proposer could charge +you withall; be euen and direct with me, whether you +were sent for or no + + Rosin. What say you? + Ham. Nay then I haue an eye of you: if you loue me +hold not off + + Guil. My Lord, we were sent for + + Ham. I will tell you why; so shall my anticipation +preuent your discouery of your secricie to the King and +Queene: moult no feather, I haue of late, but wherefore +I know not, lost all my mirth, forgone all custome of exercise; +and indeed, it goes so heauenly with my disposition; +that this goodly frame the Earth, seemes to me a sterrill +Promontory; this most excellent Canopy the Ayre, +look you, this braue ore-hanging, this Maiesticall Roofe, +fretted with golden fire: why, it appeares no other thing +to mee, then a foule and pestilent congregation of vapours. +What a piece of worke is a man! how Noble in +Reason? how infinite in faculty? in forme and mouing +how expresse and admirable? in Action, how like an Angel? +in apprehension, how like a God? the beauty of the +world, the Parragon of Animals; and yet to me, what is +this Quintessence of Dust? Man delights not me; no, +nor Woman neither; though by your smiling you seeme +to say so + + Rosin. My Lord, there was no such stuffe in my +thoughts + + Ham. Why did you laugh, when I said, Man delights +not me? + Rosin. To thinke, my Lord, if you delight not in Man, +what Lenton entertainment the Players shall receiue +from you: wee coated them on the way, and hither are +they comming to offer you Seruice + + Ham. He that playes the King shall be welcome; his +Maiesty shall haue Tribute of mee: the aduenturous +Knight shal vse his Foyle and Target: the Louer shall +not sigh gratis, the humorous man shall end his part in +peace: the Clowne shall make those laugh whose lungs +are tickled a'th' sere: and the Lady shall say her minde +freely; or the blanke Verse shall halt for't: what Players +are they? + Rosin. Euen those you were wont to take delight in +the Tragedians of the City + + Ham. How chances it they trauaile? their residence +both in reputation and profit was better both +wayes + + Rosin. I thinke their Inhibition comes by the meanes +of the late Innouation? + Ham. Doe they hold the same estimation they did +when I was in the City? Are they so follow'd? + Rosin. No indeed, they are not + + Ham. How comes it? doe they grow rusty? + Rosin. Nay, their indeauour keepes in the wonted +pace; But there is Sir an ayrie of Children, little +Yases, that crye out on the top of question; and +are most tyrannically clap't for't: these are now the +fashion, and so be-ratled the common Stages (so they +call them) that many wearing Rapiers, are affraide of +Goose-quils, and dare scarse come thither + + Ham. What are they Children? Who maintains 'em? +How are they escorted? Will they pursue the Quality no +longer then they can sing? Will they not say afterwards +if they should grow themselues to common Players (as +it is most like if their meanes are not better) their Writers +do them wrong, to make them exclaim against their +owne Succession + + Rosin. Faith there ha's bene much to do on both sides: +and the Nation holds it no sinne, to tarre them to Controuersie. +There was for a while, no mony bid for argument, +vnlesse the Poet and the Player went to Cuffes in +the Question + + Ham. Is't possible? + Guild. Oh there ha's beene much throwing about of +Braines + + Ham. Do the Boyes carry it away? + Rosin. I that they do my Lord. Hercules & his load too + + Ham. It is not strange: for mine Vnckle is King of +Denmarke, and those that would make mowes at him +while my Father liued; giue twenty, forty, an hundred +Ducates a peece, for his picture in Little. There is something +in this more then Naturall, if Philosophie could +finde it out. + +Flourish for the Players. + + Guil. There are the Players + + Ham. Gentlemen, you are welcom to Elsonower: your +hands, come: The appurtenance of Welcome, is Fashion +and Ceremony. Let me comply with you in the Garbe, +lest my extent to the Players (which I tell you must shew +fairely outward) should more appeare like entertainment +then yours. You are welcome: but my Vnckle Father, +and Aunt Mother are deceiu'd + + Guil. In what my deere Lord? + Ham. I am but mad North, North-West: when the +Winde is Southerly, I know a Hawke from a Handsaw. +Enter Polonius. + + Pol. Well be with you Gentlemen + + Ham. Hearke you Guildensterne, and you too: at each +eare a hearer: that great Baby you see there, is not yet +out of his swathing clouts + + Rosin. Happily he's the second time come to them: for +they say, an old man is twice a childe + + Ham. I will Prophesie. Hee comes to tell me of the +Players. Mark it, you say right Sir: for a Monday morning +'twas so indeed + + Pol. My Lord, I haue Newes to tell you + + Ham. My Lord, I haue Newes to tell you. +When Rossius an Actor in Rome- + Pol. The Actors are come hither my Lord + + Ham. Buzze, buzze + + Pol. Vpon mine Honor + + Ham. Then can each Actor on his Asse- + Polon. The best Actors in the world, either for Tragedie, +Comedie, Historie, Pastorall: +Pastoricall-Comicall-Historicall-Pastorall: +Tragicall-Historicall: Tragicall-Comicall-Historicall-Pastorall: +Scene indiuidible: or Poem +vnlimited. Seneca cannot be too heauy, nor Plautus +too light, for the law of Writ, and the Liberty. These are +the onely men + + Ham. O Iephta Iudge of Israel, what a Treasure had'st +thou? + Pol. What a Treasure had he, my Lord? + Ham. Why one faire Daughter, and no more, +The which he loued passing well + + Pol. Still on my Daughter + + Ham. Am I not i'th' right old Iephta? + Polon. If you call me Iephta my Lord, I haue a daughter +that I loue passing well + + Ham. Nay that followes not + + Polon. What followes then, my Lord? + Ha. Why, As by lot, God wot: and then you know, It +came to passe, as most like it was: The first rowe of the +Pons Chanson will shew you more. For looke where my +Abridgements come. +Enter foure or fiue Players. + +Y'are welcome Masters, welcome all. I am glad to see +thee well: Welcome good Friends. Oh my olde Friend? +Thy face is valiant since I saw thee last: Com'st thou to +beard me in Denmarke? What, my yong Lady and Mistris? +Byrlady your Ladiship is neerer Heauen then when +I saw you last, by the altitude of a Choppine. Pray God +your voice like a peece of vncurrant Gold be not crack'd +within the ring. Masters, you are all welcome: wee'l e'ne +to't like French Faulconers, flie at any thing we see: wee'l +haue a Speech straight. Come giue vs a tast of your quality: +come, a passionate speech + + 1.Play. What speech, my Lord? + Ham. I heard thee speak me a speech once, but it was +neuer Acted: or if it was, not aboue once, for the Play I +remember pleas'd not the Million, 'twas Cauiarie to the +Generall: but it was (as I receiu'd it, and others, whose +iudgement in such matters, cried in the top of mine) an +excellent Play; well digested in the Scoenes, set downe +with as much modestie, as cunning. I remember one said, +there was no Sallets in the lines, to make the matter sauory; +nor no matter in the phrase, that might indite the +Author of affectation, but cal'd it an honest method. One +cheefe Speech in it, I cheefely lou'd, 'twas Aeneas Tale +to Dido, and thereabout of it especially, where he speaks +of Priams slaughter. If it liue in your memory, begin at +this Line, let me see, let me see: The rugged Pyrrhus like +th'Hyrcanian Beast. It is not so: it begins with Pyrrhus +The rugged Pyrrhus, he whose Sable Armes +Blacke as his purpose, did the night resemble +When he lay couched in the Ominous Horse, +Hath now this dread and blacke Complexion smear'd +With Heraldry more dismall: Head to foote +Now is he to take Geulles, horridly Trick'd +With blood of Fathers, Mothers, Daughters, Sonnes, +Bak'd and impasted with the parching streets, +That lend a tyrannous, and damned light +To their vilde Murthers, roasted in wrath and fire, +And thus o're-sized with coagulate gore, +With eyes like Carbuncles, the hellish Pyrrhus +Olde Grandsire Priam seekes + + Pol. Fore God, my Lord, well spoken, with good accent, +and good discretion + + 1.Player. Anon he findes him, +Striking too short at Greekes. His anticke Sword, +Rebellious to his Arme, lyes where it falles +Repugnant to command: vnequall match, +Pyrrhus at Priam driues, in Rage strikes wide: +But with the whiffe and winde of his fell Sword, +Th' vnnerued Father fals. Then senselesse Illium, +Seeming to feele his blow, with flaming top +Stoopes to his Bace, and with a hideous crash +Takes Prisoner Pyrrhus eare. For loe, his Sword +Which was declining on the Milkie head +Of Reuerend Priam, seem'd i'th' Ayre to sticke: +So as a painted Tyrant Pyrrhus stood, +And like a Newtrall to his will and matter, did nothing. +But as we often see against some storme, +A silence in the Heauens, the Racke stand still, +The bold windes speechlesse, and the Orbe below +As hush as death: Anon the dreadfull Thunder +Doth rend the Region. So after Pyrrhus pause, +A rowsed Vengeance sets him new a-worke, +And neuer did the Cyclops hammers fall +On Mars his Armours, forg'd for proofe Eterne, +With lesse remorse then Pyrrhus bleeding sword +Now falles on Priam. +Out, out, thou Strumpet-Fortune, all you Gods, +In generall Synod take away her power: +Breake all the Spokes and Fallies from her wheele, +And boule the round Naue downe the hill of Heauen, +As low as to the Fiends + + Pol. This is too long + + Ham. It shall to'th Barbars, with your beard. Prythee +say on: He's for a Iigge, or a tale of Baudry, or hee +sleepes. Say on; come to Hecuba + + 1.Play. But who, O who, had seen the inobled Queen + + Ham. The inobled Queene? + Pol. That's good: Inobled Queene is good + + 1.Play. Run bare-foot vp and downe, +Threatning the flame +With Bisson Rheume: A clout about that head, +Where late the Diadem stood, and for a Robe +About her lanke and all ore-teamed Loines, +A blanket in th' Alarum of feare caught vp. +Who this had seene, with tongue in Venome steep'd, +'Gainst Fortunes State, would Treason haue pronounc'd? +But if the Gods themselues did see her then, +When she saw Pyrrhus make malicious sport +In mincing with his Sword her Husbands limbes, +The instant Burst of Clamour that she made +(Vnlesse things mortall moue them not at all) +Would haue made milche the Burning eyes of Heauen, +And passion in the Gods + + Pol. Looke where he ha's not turn'd his colour, and +ha's teares in's eyes. Pray you no more + + Ham. 'Tis well, Ile haue thee speake out the rest, +soone. Good my Lord, will you see the Players wel bestow'd. +Do ye heare, let them be well vs'd: for they are +the Abstracts and breefe Chronicles of the time. After +your death, you were better haue a bad Epitaph, then +their ill report while you liued + + Pol. My Lord, I will vse them according to their desart + + Ham. Gods bodykins man, better. Vse euerie man +after his desart, and who should scape whipping: vse +them after your own Honor and Dignity. The lesse they +deserue, the more merit is in your bountie. Take them +in + + Pol. Come sirs. + +Exit Polon. + + Ham. Follow him Friends: wee'l heare a play to morrow. +Dost thou heare me old Friend, can you play the +murther of Gonzago? + Play. I my Lord + + Ham. Wee'l ha't to morrow night. You could for a +need study a speech of some dosen or sixteene lines, which +I would set downe, and insert in't? Could ye not? + Play. I my Lord + + Ham. Very well. Follow that Lord, and looke you +mock him not. My good Friends, Ile leaue you til night +you are welcome to Elsonower? + Rosin. Good my Lord. + +Exeunt. + +Manet Hamlet. + + Ham. I so, God buy'ye: Now I am alone. +Oh what a Rogue and Pesant slaue am I? +Is it not monstrous that this Player heere, +But in a Fixion, in a dreame of Passion, +Could force his soule so to his whole conceit, +That from her working, all his visage warm'd; +Teares in his eyes, distraction in's Aspect, +A broken voyce, and his whole Function suiting +With Formes, to his Conceit? And all for nothing? +For Hecuba? +What's Hecuba to him, or he to Hecuba, +That he should weepe for her? What would he doe, +Had he the Motiue and the Cue for passion +That I haue? He would drowne the Stage with teares, +And cleaue the generall eare with horrid speech: +Make mad the guilty, and apale the free, +Confound the ignorant, and amaze indeed, +The very faculty of Eyes and Eares. Yet I, +A dull and muddy-metled Rascall, peake +Like Iohn a-dreames, vnpregnant of my cause, +And can say nothing: No, not for a King, +Vpon whose property, and most deere life, +A damn'd defeate was made. Am I a Coward? +Who calles me Villaine? breakes my pate a-crosse? +Pluckes off my Beard, and blowes it in my face? +Tweakes me by'th' Nose? giues me the Lye i'th' Throate, +As deepe as to the Lungs? Who does me this? +Ha? Why I should take it: for it cannot be, +But I am Pigeon-Liuer'd, and lacke Gall +To make Oppression bitter, or ere this, +I should haue fatted all the Region Kites +With this Slaues Offall, bloudy: a Bawdy villaine, +Remorselesse, Treacherous, Letcherous, kindles villaine! +Oh Vengeance! +Who? What an Asse am I? I sure, this is most braue, +That I, the Sonne of the Deere murthered, +Prompted to my Reuenge by Heauen, and Hell, +Must (like a Whore) vnpacke my heart with words, +And fall a Cursing like a very Drab. +A Scullion? Fye vpon't: Foh. About my Braine. +I haue heard, that guilty Creatures sitting at a Play, +Haue by the very cunning of the Scoene, +Bene strooke so to the soule, that presently +They haue proclaim'd their Malefactions. +For Murther, though it haue no tongue, will speake +With most myraculous Organ. Ile haue these Players, +Play something like the murder of my Father, +Before mine Vnkle. Ile obserue his lookes, +Ile rent him to the quicke: If he but blench +I know my course. The Spirit that I haue seene +May be the Diuell, and the Diuel hath power +T' assume a pleasing shape, yea and perhaps +Out of my Weaknesse, and my Melancholly, +As he is very potent with such Spirits, +Abuses me to damne me. Ile haue grounds +More Relatiue then this: The Play's the thing, +Wherein Ile catch the Conscience of the King. + +Exit + +Enter King, Queene, Polonius, Ophelia, Rosincrance, +Guildenstern, and +Lords. + + King. And can you by no drift of circumstance +Get from him why he puts on this Confusion: +Grating so harshly all his dayes of quiet +With turbulent and dangerous Lunacy + + Rosin. He does confesse he feeles himselfe distracted, +But from what cause he will by no meanes speake + + Guil. Nor do we finde him forward to be sounded, +But with a crafty Madnesse keepes aloofe: +When we would bring him on to some Confession +Of his true state + + Qu. Did he receiue you well? + Rosin. Most like a Gentleman + + Guild. But with much forcing of his disposition + + Rosin. Niggard of question, but of our demands +Most free in his reply + + Qu. Did you assay him to any pastime? + Rosin. Madam, it so fell out, that certaine Players +We ore-wrought on the way: of these we told him, +And there did seeme in him a kinde of ioy +To heare of it: They are about the Court, +And (as I thinke) they haue already order +This night to play before him + + Pol. 'Tis most true: +And he beseech'd me to intreate your Maiesties +To heare, and see the matter + + King. With all my heart, and it doth much content me +To heare him so inclin'd. Good Gentlemen, +Giue him a further edge, and driue his purpose on +To these delights + + Rosin. We shall my Lord. + +Exeunt. + + King. Sweet Gertrude leaue vs too, +For we haue closely sent for Hamlet hither, +That he, as 'twere by accident, may there +Affront Ophelia. Her Father, and my selfe (lawful espials) +Will so bestow our selues, that seeing vnseene +We may of their encounter frankely iudge, +And gather by him, as he is behaued, +If't be th' affliction of his loue, or no. +That thus he suffers for + + Qu. I shall obey you, +And for your part Ophelia, I do wish +That your good Beauties be the happy cause +Of Hamlets wildenesse: so shall I hope your Vertues +Will bring him to his wonted way againe, +To both your Honors + + Ophe. Madam, I wish it may + + Pol. Ophelia, walke you heere. Gracious so please ye +We will bestow our selues: Reade on this booke, +That shew of such an exercise may colour +Your lonelinesse. We are oft too blame in this, +'Tis too much prou'd, that with Deuotions visage, +And pious Action, we do surge o're +The diuell himselfe + + King. Oh 'tis true: +How smart a lash that speech doth giue my Conscience? +The Harlots Cheeke beautied with plaist'ring Art +Is not more vgly to the thing that helpes it, +Then is my deede, to my most painted word. +Oh heauie burthen! + Pol. I heare him comming, let's withdraw my Lord. + +Exeunt. + +Enter Hamlet. + + Ham. To be, or not to be, that is the Question: +Whether 'tis Nobler in the minde to suffer +The Slings and Arrowes of outragious Fortune, +Or to take Armes against a Sea of troubles, +And by opposing end them: to dye, to sleepe +No more; and by a sleepe, to say we end +The Heart-ake, and the thousand Naturall shockes +That Flesh is heyre too? 'Tis a consummation +Deuoutly to be wish'd. To dye to sleepe, +To sleepe, perchance to Dreame; I, there's the rub, +For in that sleepe of death, what dreames may come, +When we haue shuffel'd off this mortall coile, +Must giue vs pawse. There's the respect +That makes Calamity of so long life: +For who would beare the Whips and Scornes of time, +The Oppressors wrong, the poore mans Contumely, +The pangs of dispriz'd Loue, the Lawes delay, +The insolence of Office, and the Spurnes +That patient merit of the vnworthy takes, +When he himselfe might his Quietus make +With a bare Bodkin? Who would these Fardles beare +To grunt and sweat vnder a weary life, +But that the dread of something after death, +The vndiscouered Countrey, from whose Borne +No Traueller returnes, Puzels the will, +And makes vs rather beare those illes we haue, +Then flye to others that we know not of. +Thus Conscience does make Cowards of vs all, +And thus the Natiue hew of Resolution +Is sicklied o're, with the pale cast of Thought, +And enterprizes of great pith and moment, +With this regard their Currants turne away, +And loose the name of Action. Soft you now, +The faire Ophelia? Nimph, in thy Orizons +Be all my sinnes remembred + + Ophe. Good my Lord, +How does your Honor for this many a day? + Ham. I humbly thanke you: well, well, well + + Ophe. My Lord, I haue Remembrances of yours, +That I haue longed long to re-deliuer. +I pray you now, receiue them + + Ham. No, no, I neuer gaue you ought + + Ophe. My honor'd Lord, I know right well you did, +And with them words of so sweet breath compos'd, +As made the things more rich, then perfume left: +Take these againe, for to the Noble minde +Rich gifts wax poore, when giuers proue vnkinde. +There my Lord + + Ham. Ha, ha: Are you honest? + Ophe. My Lord + + Ham. Are you faire? + Ophe. What meanes your Lordship? + Ham. That if you be honest and faire, your Honesty +should admit no discourse to your Beautie + + Ophe. Could Beautie my Lord, haue better Comerce +then your Honestie? + Ham. I trulie: for the power of Beautie, will sooner +transforme Honestie from what is, to a Bawd, then the +force of Honestie can translate Beautie into his likenesse. +This was sometime a Paradox, but now the time giues it +proofe. I did loue you once + + Ophe. Indeed my Lord, you made me beleeue so + + Ham. You should not haue beleeued me. For vertue +cannot so innocculate our old stocke, but we shall rellish +of it. I loued you not + + Ophe. I was the more deceiued + + Ham. Get thee to a Nunnerie. Why would'st thou +be a breeder of Sinners? I am my selfe indifferent honest, +but yet I could accuse me of such things, that it were better +my Mother had not borne me. I am very prowd, reuengefull, +Ambitious, with more offences at my becke, +then I haue thoughts to put them in imagination, to giue +them shape, or time to acte them in. What should such +Fellowes as I do, crawling betweene Heauen and Earth. +We are arrant Knaues all, beleeue none of vs. Goe thy +wayes to a Nunnery. Where's your Father? + Ophe. At home, my Lord + + Ham. Let the doores be shut vpon him, that he may +play the Foole no way, but in's owne house. Farewell + + Ophe. O helpe him, you sweet Heauens + + Ham. If thou doest Marry, Ile giue thee this Plague +for thy Dowrie. Be thou as chast as Ice, as pure as Snow, +thou shalt not escape Calumny. Get thee to a Nunnery. +Go, Farewell. Or if thou wilt needs Marry, marry a fool: +for Wise men know well enough, what monsters you +make of them. To a Nunnery go, and quickly too. Farwell + + Ophe. O heauenly Powers, restore him + + Ham. I haue heard of your pratlings too wel enough. +God has giuen you one pace, and you make your selfe another: +you gidge, you amble, and you lispe, and nickname +Gods creatures, and make your Wantonnesse, your Ignorance. +Go too, Ile no more on't, it hath made me mad. +I say, we will haue no more Marriages. Those that are +married already, all but one shall liue, the rest shall keep +as they are. To a Nunnery, go. + +Exit Hamlet. + + Ophe. O what a Noble minde is heere o're-throwne? +The Courtiers, Soldiers, Schollers: Eye, tongue, sword, +Th' expectansie and Rose of the faire State, +The glasse of Fashion, and the mould of Forme, +Th' obseru'd of all Obseruers, quite, quite downe. +Haue I of Ladies most deiect and wretched, +That suck'd the Honie of his Musicke Vowes: +Now see that Noble, and most Soueraigne Reason, +Like sweet Bels iangled out of tune, and harsh, +That vnmatch'd Forme and Feature of blowne youth, +Blasted with extasie. Oh woe is me, +T'haue seene what I haue seene: see what I see. +Enter King, and Polonius. + + King. Loue? His affections do not that way tend, +Nor what he spake, though it lack'd Forme a little, +Was not like Madnesse. There's something in his soule? +O're which his Melancholly sits on brood, +And I do doubt the hatch, and the disclose +Will be some danger, which to preuent +I haue in quicke determination +Thus set it downe. He shall with speed to England +For the demand of our neglected Tribute: +Haply the Seas and Countries different +With variable Obiects, shall expell +This something setled matter in his heart: +Whereon his Braines still beating, puts him thus +From fashion of himselfe. What thinke you on't? + Pol. It shall do well. But yet do I beleeue +The Origin and Commencement of this greefe +Sprung from neglected loue. How now Ophelia? +You neede not tell vs, what Lord Hamlet saide, +We heard it all. My Lord, do as you please, +But if you hold it fit after the Play, +Let his Queene Mother all alone intreat him +To shew his Greefes: let her be round with him, +And Ile be plac'd so, please you in the eare +Of all their Conference. If she finde him not, +To England send him: Or confine him where +Your wisedome best shall thinke + + King. It shall be so: +Madnesse in great Ones, must not vnwatch'd go. + +Exeunt. + +Enter Hamlet, and two or three of the Players. + + Ham. Speake the Speech I pray you, as I pronounc'd +it to you trippingly on the Tongue: But if you mouth it, +as many of your Players do, I had as liue the Town-Cryer +had spoke my Lines: Nor do not saw the Ayre too much +your hand thus, but vse all gently; for in the verie Torrent, +Tempest, and (as I say) the Whirle-winde of +Passion, you must acquire and beget a Temperance that +may giue it Smoothnesse. O it offends mee to the Soule, +to see a robustious Pery-wig-pated Fellow, teare a Passion +to tatters, to verie ragges, to split the eares of the +Groundlings: who (for the most part) are capeable of +nothing, but inexplicable dumbe shewes, & noise: I could +haue such a Fellow whipt for o're-doing Termagant: it +outHerod's Herod. Pray you auoid it + + Player. I warrant your Honor + + Ham. Be not too tame neyther: but let your owne +Discretion be your Tutor. Sute the Action to the Word, +the Word to the Action, with this speciall obseruance: +That you ore-stop not the modestie of Nature; for any +thing so ouer-done, is fro[m] the purpose of Playing, whose +end both at the first and now, was and is, to hold as 'twer +the Mirrour vp to Nature; to shew Vertue her owne +Feature, Scorne her owne Image, and the verie Age and +Bodie of the Time, his forme and pressure. Now, this +ouer-done, or come tardie off, though it make the vnskilfull +laugh, cannot but make the Iudicious greeue; The +censure of the which One, must in your allowance o'reway +a whole Theater of Others. Oh, there bee Players +that I haue seene Play, and heard others praise, and that +highly (not to speake it prophanely) that neyther hauing +the accent of Christians, nor the gate of Christian, Pagan, +or Norman, haue so strutted and bellowed, that I haue +thought some of Natures Iouerney-men had made men, +and not made them well, they imitated Humanity so abhominably + + Play. I hope we haue reform'd that indifferently with +vs, Sir + + Ham. O reforme it altogether. And let those that +play your Clownes, speake no more then is set downe for +them. For there be of them, that will themselues laugh, +to set on some quantitie of barren Spectators to laugh +too, though in the meane time, some necessary Question +of the Play be then to be considered: that's Villanous, & +shewes a most pittifull Ambition in the Foole that vses +it. Go make you readie. + +Exit Players. + +Enter Polonius, Rosincrance, and Guildensterne. + +How now my Lord, +Will the King heare this peece of Worke? + Pol. And the Queene too, and that presently + + Ham. Bid the Players make hast. + +Exit Polonius. + +Will you two helpe to hasten them? + Both. We will my Lord. + +Exeunt. + +Enter Horatio. + + Ham. What hoa, Horatio? + Hora. Heere sweet Lord, at your Seruice + + Ham. Horatio, thou art eene as iust a man +As ere my Conuersation coap'd withall + + Hora. O my deere Lord + + Ham. Nay, do not thinke I flatter: +For what aduancement may I hope from thee, +That no Reuennew hast, but thy good spirits +To feed & cloath thee. Why shold the poor be flatter'd? +No, let the Candied tongue, like absurd pompe, +And crooke the pregnant Hindges of the knee, +Where thrift may follow faining? Dost thou heare, +Since my deere Soule was Mistris of my choyse, +And could of men distinguish, her election +Hath seal'd thee for her selfe. For thou hast bene +As one in suffering all, that suffers nothing. +A man that Fortunes buffets, and Rewards +Hath 'tane with equall Thankes. And blest are those, +Whose Blood and Iudgement are so well co-mingled, +That they are not a Pipe for Fortunes finger. +To sound what stop she please. Giue me that man, +That is not Passions Slaue, and I will weare him +In my hearts Core. I, in my Heart of heart, +As I do thee. Something too much of this. +There is a Play to night to before the King. +One Scoene of it comes neere the Circumstance +Which I haue told thee, of my Fathers death. +I prythee, when thou see'st that Acte a-foot, +Euen with the verie Comment of my Soule +Obserue mine Vnkle: If his occulted guilt, +Do not it selfe vnkennell in one speech, +It is a damned Ghost that we haue seene: +And my Imaginations are as foule +As Vulcans Stythe. Giue him needfull note, +For I mine eyes will riuet to his Face: +And after we will both our iudgements ioyne, +To censure of his seeming + + Hora. Well my Lord. +If he steale ought the whil'st this Play is Playing, +And scape detecting, I will pay the Theft. +Enter King, Queene, Polonius, Ophelia, Rosincrance, +Guildensterne, and +other Lords attendant with his Guard carrying Torches. Danish +March. Sound +a Flourish. + + Ham. They are comming to the Play: I must be idle. +Get you a place + + King. How fares our Cosin Hamlet? + Ham. Excellent Ifaith, of the Camelions dish: I eate +the Ayre promise-cramm'd, you cannot feed Capons so + + King. I haue nothing with this answer Hamlet, these +words are not mine + + Ham. No, nor mine. Now my Lord, you plaid once +i'th' Vniuersity, you say? + Polon. That I did my Lord, and was accounted a good +Actor + + Ham. And what did you enact? + Pol. I did enact Iulius Caesar, I was kill'd i'th' Capitol: +Brutus kill'd me + + Ham. It was a bruite part of him, to kill so Capitall a +Calfe there. Be the Players ready? + Rosin. I my Lord, they stay vpon your patience + + Qu. Come hither my good Hamlet, sit by me + + Ha. No good Mother, here's Mettle more attractiue + + Pol. Oh ho, do you marke that? + Ham. Ladie, shall I lye in your Lap? + Ophe. No my Lord + + Ham. I meane, my Head vpon your Lap? + Ophe. I my Lord + + Ham. Do you thinke I meant Country matters? + Ophe. I thinke nothing, my Lord + + Ham. That's a faire thought to ly betweene Maids legs + Ophe. What is my Lord? + Ham. Nothing + + Ophe. You are merrie, my Lord? + Ham. Who I? + Ophe. I my Lord + + Ham. Oh God, your onely Iigge-maker: what should +a man do, but be merrie. For looke you how cheerefully +my Mother lookes, and my Father dyed within's two +Houres + + Ophe. Nay, 'tis twice two moneths, my Lord + + Ham. So long? Nay then let the Diuel weare blacke, +for Ile haue a suite of Sables. Oh Heauens! dye two moneths +ago, and not forgotten yet? Then there's hope, a +great mans Memorie, may out-liue his life halfe a yeare: +But byrlady he must builde Churches then: or else shall +he suffer not thinking on, with the Hoby-horsse, whose +Epitaph is, For o, For o, the Hoby-horse is forgot. + +Hoboyes play. The dumbe shew enters. + +Enter a King and Queene, very louingly; the Queene embracing +him. She +kneeles, and makes shew of Protestation vnto him. He takes her +vp, and +declines his head vpon her neck. Layes him downe vpon a Banke +of Flowers. +She seeing him a-sleepe, leaues him. Anon comes in a Fellow, +takes off his +Crowne, kisses it, and powres poyson in the Kings eares, and +Exits. The +Queene returnes, findes the King dead, and makes passionate +Action. The +Poysoner, with some two or three Mutes comes in againe, seeming +to lament +with her. The dead body is carried away: The Poysoner Wooes the +Queene with +Gifts, she seemes loath and vnwilling awhile, but in the end, +accepts his +loue. + +Exeunt. + + Ophe. What meanes this, my Lord? + Ham. Marry this is Miching Malicho, that meanes +Mischeefe + + Ophe. Belike this shew imports the Argument of the +Play? + Ham. We shall know by these Fellowes: the Players +cannot keepe counsell, they'l tell all + + Ophe. Will they tell vs what this shew meant? + Ham. I, or any shew that you'l shew him. Bee not +you asham'd to shew, hee'l not shame to tell you what it +meanes + + Ophe. You are naught, you are naught, Ile marke the +Play. +Enter Prologue. + +For vs, and for our Tragedie, +Heere stooping to your Clemencie: +We begge your hearing Patientlie + + Ham. Is this a Prologue, or the Poesie of a Ring? + Ophe. 'Tis briefe my Lord + + Ham. As Womans loue. +Enter King and his Queene. + + King. Full thirtie times hath Phoebus Cart gon round, +Neptunes salt Wash, and Tellus Orbed ground: +And thirtie dozen Moones with borrowed sheene, +About the World haue times twelue thirties beene, +Since loue our hearts, and Hymen did our hands +Vnite comutuall, in most sacred Bands + + Bap. So many iournies may the Sunne and Moone +Make vs againe count o're, ere loue be done. +But woe is me, you are so sicke of late, +So farre from cheere, and from your former state, +That I distrust you: yet though I distrust, +Discomfort you (my Lord) it nothing must: +For womens Feare and Loue, holds quantitie, +In neither ought, or in extremity: +Now what my loue is, proofe hath made you know, +And as my Loue is siz'd, my Feare is so + + King. Faith I must leaue thee Loue, and shortly too: +My operant Powers my Functions leaue to do: +And thou shalt liue in this faire world behinde, +Honour'd, belou'd, and haply, one as kinde. +For Husband shalt thou- + Bap. Oh confound the rest: +Such Loue, must needs be Treason in my brest: +In second Husband, let me be accurst, +None wed the second, but who kill'd the first + + Ham. Wormwood, Wormwood + + Bapt. The instances that second Marriage moue, +Are base respects of Thrift, but none of Loue. +A second time, I kill my Husband dead, +When second Husband kisses me in Bed + + King. I do beleeue you. Think what now you speak: +But what we do determine, oft we breake: +Purpose is but the slaue to Memorie, +Of violent Birth, but poore validitie: +Which now like Fruite vnripe stickes on the Tree, +But fall vnshaken, when they mellow bee. +Most necessary 'tis, that we forget +To pay our selues, what to our selues is debt: +What to our selues in passion we propose, +The passion ending, doth the purpose lose. +The violence of other Greefe or Ioy, +Their owne ennactors with themselues destroy: +Where Ioy most Reuels, Greefe doth most lament; +Greefe ioyes, Ioy greeues on slender accident. +This world is not for aye, nor 'tis not strange +That euen our Loues should with our Fortunes change. +For 'tis a question left vs yet to proue, +Whether Loue lead Fortune, or else Fortune Loue. +The great man downe, you marke his fauourites flies, +The poore aduanc'd, makes Friends of Enemies: +And hitherto doth Loue on Fortune tend, +For who not needs, shall neuer lacke a Frend: +And who in want a hollow Friend doth try, +Directly seasons him his Enemie. +But orderly to end, where I begun, +Our Willes and Fates do so contrary run, +That our Deuices still are ouerthrowne, +Our thoughts are ours, their ends none of our owne. +So thinke thou wilt no second Husband wed. +But die thy thoughts, when thy first Lord is dead + + Bap. Nor Earth to giue me food, nor Heauen light, +Sport and repose locke from me day and night: +Each opposite that blankes the face of ioy, +Meet what I would haue well, and it destroy: +Both heere, and hence, pursue me lasting strife, +If once a Widdow, euer I be Wife + + Ham. If she should breake it now + + King. 'Tis deepely sworne: +Sweet, leaue me heere a while, +My spirits grow dull, and faine I would beguile +The tedious day with sleepe + + Qu. Sleepe rocke thy Braine, + +Sleepes + +And neuer come mischance betweene vs twaine. + +Exit + + Ham. Madam, how like you this Play? + Qu. The Lady protests to much me thinkes + + Ham. Oh but shee'l keepe her word + + King. Haue you heard the Argument, is there no Offence +in't? + Ham. No, no, they do but iest, poyson in iest, no Offence +i'th' world + + King. What do you call the Play? + Ham. The Mouse-trap: Marry how? Tropically: +This Play is the Image of a murder done in Vienna: Gonzago +is the Dukes name, his wife Baptista: you shall see +anon: 'tis a knauish peece of worke: But what o'that? +Your Maiestie, and wee that haue free soules, it touches +vs not: let the gall'd iade winch: our withers are vnrung. +Enter Lucianus. + +This is one Lucianus nephew to the King + + Ophe. You are a good Chorus, my Lord + + Ham. I could interpret betweene you and your loue: +if I could see the Puppets dallying + + Ophe. You are keene my Lord, you are keene + + Ham. It would cost you a groaning, to take off my +edge + + Ophe. Still better and worse + + Ham. So you mistake Husbands. +Begin Murderer. Pox, leaue thy damnable Faces, and +begin. Come, the croaking Rauen doth bellow for Reuenge + + Lucian. Thoughts blacke, hands apt, +Drugges fit, and Time agreeing: +Confederate season, else, no Creature seeing: +Thou mixture ranke, of Midnight Weeds collected, +With Hecats Ban, thrice blasted, thrice infected, +Thy naturall Magicke, and dire propertie, +On wholsome life, vsurpe immediately. + +Powres the poyson in his eares. + + Ham. He poysons him i'th' Garden for's estate: His +name's Gonzago: the Story is extant and writ in choyce +Italian. You shall see anon how the Murtherer gets the +loue of Gonzago's wife + + Ophe. The King rises + + Ham. What, frighted with false fire + + Qu. How fares my Lord? + Pol. Giue o're the Play + + King. Giue me some Light. Away + + All. Lights, Lights, Lights. + +Exeunt. + +Manet Hamlet & Horatio. + + Ham. Why let the strucken Deere go weepe, +The Hart vngalled play: +For some must watch, while some must sleepe; +So runnes the world away. +Would not this Sir, and a Forrest of Feathers, if the rest of +my Fortunes turne Turke with me; with two Prouinciall +Roses on my rac'd Shooes, get me a Fellowship in a crie +of Players sir + + Hor. Halfe a share + + Ham. A whole one I, +For thou dost know: Oh Damon deere, +This Realme dismantled was of Ioue himselfe, +And now reignes heere. +A verie verie Paiocke + + Hora. You might haue Rim'd + + Ham. Oh good Horatio, Ile take the Ghosts word for +a thousand pound. Did'st perceiue? + Hora. Verie well my Lord + + Ham. Vpon the talke of the poysoning? + Hora. I did verie well note him. +Enter Rosincrance and Guildensterne. + + Ham. Oh, ha? Come some Musick. Come y Recorders: +For if the King like not the Comedie, +Why then belike he likes it not perdie. +Come some Musicke + + Guild. Good my Lord, vouchsafe me a word with you + + Ham. Sir, a whole History + + Guild. The King, sir + + Ham. I sir, what of him? + Guild. Is in his retyrement, maruellous distemper'd + + Ham. With drinke Sir? + Guild. No my Lord, rather with choller + + Ham. Your wisedome should shew it selfe more richer, +to signifie this to his Doctor: for for me to put him +to his Purgation, would perhaps plundge him into farre +more Choller + + Guild. Good my Lord put your discourse into some +frame, and start not so wildely from my affayre + + Ham. I am tame Sir, pronounce + + Guild. The Queene your Mother, in most great affliction +of spirit, hath sent me to you + + Ham. You are welcome + + Guild. Nay, good my Lord, this courtesie is not of +the right breed. If it shall please you to make me a wholsome +answer, I will doe your Mothers command'ment: +if not, your pardon, and my returne shall bee the end of +my Businesse + + Ham. Sir, I cannot + + Guild. What, my Lord? + Ham. Make you a wholsome answere: my wits diseas'd. +But sir, such answers as I can make, you shal command: +or rather you say, my Mother: therfore no more +but to the matter. My Mother you say + + Rosin. Then thus she sayes: your behauior hath stroke +her into amazement, and admiration + + Ham. Oh wonderfull Sonne, that can so astonish a +Mother. But is there no sequell at the heeles of this Mothers +admiration? + Rosin. She desires to speake with you in her Closset, +ere you go to bed + + Ham. We shall obey, were she ten times our Mother. +Haue you any further Trade with vs? + Rosin. My Lord, you once did loue me + + Ham. So I do still, by these pickers and stealers + + Rosin. Good my Lord, what is your cause of distemper? +You do freely barre the doore of your owne Libertie, +if you deny your greefes to your Friend + + Ham. Sir I lacke Aduancement + + Rosin. How can that be, when you haue the voyce of +the King himselfe, for your Succession in Denmarke? + Ham. I, but while the grasse growes, the Prouerbe is +something musty. +Enter one with a Recorder. + +O the Recorder. Let me see, to withdraw with you, why +do you go about to recouer the winde of mee, as if you +would driue me into a toyle? + Guild. O my Lord, if my Dutie be too bold, my loue +is too vnmannerly + + Ham. I do not well vnderstand that. Will you play +vpon this Pipe? + Guild. My Lord, I cannot + + Ham. I pray you + + Guild. Beleeue me, I cannot + + Ham. I do beseech you + + Guild. I know no touch of it, my Lord + + Ham. 'Tis as easie as lying: gouerne these Ventiges +with your finger and thumbe, giue it breath with your +mouth, and it will discourse most excellent Musicke. +Looke you, these are the stoppes + + Guild. But these cannot I command to any vtterance +of hermony, I haue not the skill + + Ham. Why looke you now, how vnworthy a thing +you make of me: you would play vpon mee; you would +seeme to know my stops: you would pluck out the heart +of my Mysterie; you would sound mee from my lowest +Note, to the top of my Compasse: and there is much Musicke, +excellent Voice, in this little Organe, yet cannot +you make it. Why do you thinke, that I am easier to bee +plaid on, then a Pipe? Call me what Instrument you will, +though you can fret me, you cannot play vpon me. God +blesse you Sir. +Enter Polonius. + + Polon. My Lord; the Queene would speak with you, +and presently + + Ham. Do you see that Clowd? that's almost in shape +like a Camell + + Polon. By'th' Masse, and it's like a Camell indeed + + Ham. Me thinkes it is like a Weazell + + Polon. It is back'd like a Weazell + + Ham. Or like a Whale? + Polon. Verie like a Whale + + Ham. Then will I come to my Mother, by and by: +They foole me to the top of my bent. +I will come by and by + + Polon. I will say so. +Enter. + + Ham. By and by, is easily said. Leaue me Friends: +'Tis now the verie witching time of night, +When Churchyards yawne, and Hell it selfe breaths out +Contagion to this world. Now could I drink hot blood, +And do such bitter businesse as the day +Would quake to looke on. Soft now, to my Mother: +Oh Heart, loose not thy Nature; let not euer +The Soule of Nero, enter this firme bosome: +Let me be cruell, not vnnaturall, +I will speake Daggers to her, but vse none: +My Tongue and Soule in this be Hypocrites. +How in my words someuer she be shent, +To giue them Seales, neuer my Soule consent. +Enter King, Rosincrance, and Guildensterne. + + King. I like him not, nor stands it safe with vs, +To let his madnesse range. Therefore prepare you, +I your Commission will forthwith dispatch, +And he to England shall along with you: +The termes of our estate, may not endure +Hazard so dangerous as doth hourely grow +Out of his Lunacies + + Guild. We will our selues prouide: +Most holie and Religious feare it is +To keepe those many many bodies safe +That liue and feede vpon your Maiestie + + Rosin. The single +And peculiar life is bound +With all the strength and Armour of the minde, +To keepe it selfe from noyance: but much more, +That Spirit, vpon whose spirit depends and rests +The liues of many, the cease of Maiestie +Dies not alone; but like a Gulfe doth draw +What's neere it, with it. It is a massie wheele +Fixt on the Somnet of the highest Mount. +To whose huge Spoakes, ten thousand lesser things +Are mortiz'd and adioyn'd: which when it falles, +Each small annexment, pettie consequence +Attends the boystrous Ruine. Neuer alone +Did the King sighe, but with a generall grone + + King. Arme you, I pray you to this speedie Voyage; +For we will Fetters put vpon this feare, +Which now goes too free-footed + + Both. We will haste vs. + +Exeunt. Gent. + +Enter Polonius. + + Pol. My Lord, he's going to his Mothers Closset: +Behinde the Arras Ile conuey my selfe +To heare the Processe. Ile warrant shee'l tax him home, +And as you said, and wisely was it said, +'Tis meete that some more audience then a Mother, +Since Nature makes them partiall, should o're-heare +The speech of vantage. Fare you well my Liege, +Ile call vpon you ere you go to bed, +And tell you what I know + + King. Thankes deere my Lord. +Oh my offence is ranke, it smels to heauen, +It hath the primall eldest curse vpon't, +A Brothers murther. Pray can I not, +Though inclination be as sharpe as will: +My stronger guilt, defeats my strong intent, +And like a man to double businesse bound, +I stand in pause where I shall first begin, +And both neglect; what if this cursed hand +Were thicker then it selfe with Brothers blood, +Is there not Raine enough in the sweet Heauens +To wash it white as Snow? Whereto serues mercy, +But to confront the visage of Offence? +And what's in Prayer, but this two-fold force, +To be fore-stalled ere we come to fall, +Or pardon'd being downe? Then Ile looke vp, +My fault is past. But oh, what forme of Prayer +Can serue my turne? Forgiue me my foule Murther: +That cannot be, since I am still possest +Of those effects for which I did the Murther. +My Crowne, mine owne Ambition, and my Queene: +May one be pardon'd, and retaine th' offence? +In the corrupted currants of this world, +Offences gilded hand may shoue by Iustice, +And oft 'tis seene, the wicked prize it selfe +Buyes out the Law; but 'tis not so aboue, +There is no shuffling, there the Action lyes +In his true Nature, and we our selues compell'd +Euen to the teeth and forehead of our faults, +To giue in euidence. What then? What rests? +Try what Repentance can. What can it not? +Yet what can it, when one cannot repent? +Oh wretched state! Oh bosome, blacke as death! +Oh limed soule, that strugling to be free, +Art more ingag'd: Helpe Angels, make assay: +Bow stubborne knees, and heart with strings of Steele, +Be soft as sinewes of the new-borne Babe, +All may be well. +Enter Hamlet. + + Ham. Now might I do it pat, now he is praying, +And now Ile doo't, and so he goes to Heauen, +And so am I reueng'd: that would be scann'd, +A Villaine killes my Father, and for that +I his foule Sonne, do this same Villaine send +To heauen. Oh this is hyre and Sallery, not Reuenge. +He tooke my Father grossely, full of bread, +With all his Crimes broad blowne, as fresh as May, +And how his Audit stands, who knowes, saue Heauen: +But in our circumstance and course of thought +'Tis heauie with him: and am I then reueng'd, +To take him in the purging of his Soule, +When he is fit and season'd for his passage? No. +Vp Sword, and know thou a more horrid hent +When he is drunke asleepe: or in his Rage, +Or in th' incestuous pleasure of his bed, +At gaming, swearing, or about some acte +That ha's no rellish of Saluation in't, +Then trip him, that his heeles may kicke at Heauen, +And that his Soule may be as damn'd and blacke +As Hell, whereto it goes. My Mother stayes, +This Physicke but prolongs thy sickly dayes. +Enter. + + King. My words flye vp, my thoughts remain below, +Words without thoughts, neuer to Heauen go. +Enter. + +Enter Queene and Polonius. + + Pol. He will come straight: +Looke you lay home to him, +Tell him his prankes haue been too broad to beare with, +And that your Grace hath screen'd, and stoode betweene +Much heate, and him. Ile silence me e'ene heere: +Pray you be round with him + + Ham. within. Mother, mother, mother + + Qu. Ile warrant you, feare me not. +Withdraw, I heare him coming. +Enter Hamlet. + + Ham. Now Mother, what's the matter? + Qu. Hamlet, thou hast thy Father much offended + + + Ham. Mother, you haue my Father much offended + + Qu. Come, come, you answer with an idle tongue + + Ham. Go, go, you question with an idle tongue + + Qu. Why how now Hamlet? + Ham. Whats the matter now? + Qu. Haue you forgot me? + Ham. No by the Rood, not so: +You are the Queene, your Husbands Brothers wife, +But would you were not so. You are my Mother + + Qu. Nay, then Ile set those to you that can speake + + Ham. Come, come, and sit you downe, you shall not +boudge: +You go not till I set you vp a glasse, +Where you may see the inmost part of you? + Qu. What wilt thou do? thou wilt not murther me? +Helpe, helpe, hoa + + Pol. What hoa, helpe, helpe, helpe + + Ham. How now, a Rat? dead for a Ducate, dead + + Pol. Oh I am slaine. + +Killes Polonius + + Qu. Oh me, what hast thou done? + Ham. Nay I know not, is it the King? + Qu. Oh what a rash, and bloody deed is this? + Ham. A bloody deed, almost as bad good Mother, +As kill a King, and marrie with his Brother + + Qu. As kill a King? + Ham. I Lady, 'twas my word. +Thou wretched, rash, intruding foole farewell, +I tooke thee for thy Betters, take thy Fortune, +Thou find'st to be too busie, is some danger. +Leaue wringing of your hands, peace, sit you downe, +And let me wring your heart, for so I shall +If it be made of penetrable stuffe; +If damned Custome haue not braz'd it so, +That it is proofe and bulwarke against Sense + + Qu. What haue I done, that thou dar'st wag thy tong, +In noise so rude against me? + Ham. Such an Act +That blurres the grace and blush of Modestie, +Cals Vertue Hypocrite, takes off the Rose +From the faire forehead of an innocent loue, +And makes a blister there. Makes marriage vowes +As false as Dicers Oathes. Oh such a deed, +As from the body of Contraction pluckes +The very soule, and sweete Religion makes +A rapsidie of words. Heauens face doth glow, +Yea this solidity and compound masse, +With tristfull visage as against the doome, +Is thought-sicke at the act + + Qu. Aye me; what act, that roares so lowd, & thunders +in the Index + + Ham. Looke heere vpon this Picture, and on this, +The counterfet presentment of two Brothers: +See what a grace was seated on his Brow, +Hyperions curles, the front of Ioue himselfe, +An eye like Mars, to threaten or command +A Station, like the Herald Mercurie +New lighted on a heauen-kissing hill: +A Combination, and a forme indeed, +Where euery God did seeme to set his Seale, +To giue the world assurance of a man. +This was your Husband. Looke you now what followes. +Heere is your Husband, like a Mildew'd eare +Blasting his wholsom breath. Haue you eyes? +Could you on this faire Mountaine leaue to feed, +And batten on this Moore? Ha? Haue you eyes? +You cannot call it Loue: For at your age, +The hey-day in the blood is tame, it's humble, +And waites vpon the Iudgement: and what Iudgement +Would step from this, to this? What diuell was't, +That thus hath cousend you at hoodman-blinde? +O Shame! where is thy Blush? Rebellious Hell, +If thou canst mutine in a Matrons bones, +To flaming youth, let Vertue be as waxe. +And melt in her owne fire. Proclaime no shame, +When the compulsiue Ardure giues the charge, +Since Frost it selfe, as actiuely doth burne, +As Reason panders Will + + Qu. O Hamlet, speake no more. +Thou turn'st mine eyes into my very soule, +And there I see such blacke and grained spots, +As will not leaue their Tinct + + Ham. Nay, but to liue +In the ranke sweat of an enseamed bed, +Stew'd in Corruption; honying and making loue +Ouer the nasty Stye + + Qu. Oh speake to me, no more, +These words like Daggers enter in mine eares. +No more sweet Hamlet + + Ham. A Murderer, and a Villaine: +A Slaue, that is not twentieth part the tythe +Of your precedent Lord. A vice of Kings, +A Cutpurse of the Empire and the Rule. +That from a shelfe, the precious Diadem stole, +And put it in his Pocket + + Qu. No more. +Enter Ghost. + + Ham. A King of shreds and patches. +Saue me; and houer o're me with your wings +You heauenly Guards. What would your gracious figure? + Qu. Alas he's mad + + Ham. Do you not come your tardy Sonne to chide, +That laps't in Time and Passion, lets go by +Th' important acting of your dread command? Oh say + + Ghost. Do not forget: this Visitation +Is but to whet thy almost blunted purpose. +But looke, Amazement on thy Mother sits; +O step betweene her, and her fighting Soule, +Conceit in weakest bodies, strongest workes. +Speake to her Hamlet + + Ham. How is it with you Lady? + Qu. Alas, how is't with you? +That you bend your eye on vacancie, +And with their corporall ayre do hold discourse. +Forth at your eyes, your spirits wildely peepe, +And as the sleeping Soldiours in th' Alarme, +Your bedded haire, like life in excrements, +Start vp, and stand an end. Oh gentle Sonne, +Vpon the heate and flame of thy distemper +Sprinkle coole patience. Whereon do you looke? + Ham. On him, on him: look you how pale he glares, +His forme and cause conioyn'd, preaching to stones, +Would make them capeable. Do not looke vpon me, +Least with this pitteous action you conuert +My sterne effects: then what I haue to do, +Will want true colour; teares perchance for blood + + Qu. To who do you speake this? + Ham. Do you see nothing there? + Qu. Nothing at all, yet all that is I see + + Ham. Nor did you nothing heare? + Qu. No, nothing but our selues + + Ham. Why look you there: looke how it steals away: +My Father in his habite, as he liued, +Looke where he goes euen now out at the Portall. +Enter. + + Qu. This is the very coynage of your Braine, +This bodilesse Creation extasie is very cunning in + + Ham. Extasie? +My Pulse as yours doth temperately keepe time, +And makes as healthfull Musicke. It is not madnesse +That I haue vttered; bring me to the Test +And I the matter will re-word: which madnesse +Would gamboll from. Mother, for loue of Grace, +Lay not a flattering Vnction to your soule, +That not your trespasse, but my madnesse speakes: +It will but skin and filme the Vlcerous place, +Whil'st ranke Corruption mining all within, +Infects vnseene. Confesse your selfe to Heauen, +Repent what's past, auoyd what is to come, +And do not spred the Compost on the Weedes, +To make them ranke. Forgiue me this my Vertue, +For in the fatnesse of this pursie times, +Vertue it selfe, of Vice must pardon begge, +Yea courb, and woe, for leaue to do him good + + Qu. Oh Hamlet, +Thou hast cleft my heart in twaine + + Ham. O throw away the worser part of it, +And liue the purer with the other halfe. +Good night, but go not to mine Vnkles bed, +Assume a Vertue, if you haue it not, refraine to night, +And that shall lend a kinde of easinesse +To the next abstinence. Once more goodnight, +And when you are desirous to be blest, +Ile blessing begge of you. For this same Lord, +I do repent: but heauen hath pleas'd it so, +To punish me with this, and this with me, +That I must be their Scourge and Minister. +I will bestow him, and will answer well +The death I gaue him: so againe, good night. +I must be cruell, onely to be kinde; +Thus bad begins and worse remaines behinde + + Qu. What shall I do? + Ham. Not this by no meanes that I bid you do: +Let the blunt King tempt you againe to bed, +Pinch Wanton on your cheeke, call you his Mouse, +And let him for a paire of reechie kisses, +Or padling in your necke with his damn'd Fingers, +Make you to rauell all this matter out, +That I essentially am not in madnesse, +But made in craft. 'Twere good you let him know, +For who that's but a Queene, faire, sober, wise, +Would from a Paddocke, from a Bat, a Gibbe, +Such deere concernings hide, Who would do so, +No in despight of Sense and Secrecie, +Vnpegge the Basket on the houses top: +Let the Birds flye, and like the famous Ape +To try Conclusions in the Basket, creepe +And breake your owne necke downe + + Qu. Be thou assur'd, if words be made of breath, +And breath of life: I haue no life to breath +What thou hast saide to me + + Ham. I must to England, you know that? + Qu. Alacke I had forgot: 'Tis so concluded on + + Ham. This man shall set me packing: +Ile lugge the Guts into the Neighbor roome, +Mother goodnight. Indeede this Counsellor +Is now most still, most secret, and most graue, +Who was in life, a foolish prating Knaue. +Come sir, to draw toward an end with you. +Good night Mother. +Exit Hamlet tugging in Polonius. + +Enter King. + + King. There's matters in these sighes. +These profound heaues +You must translate; Tis fit we vnderstand them. +Where is your Sonne? + Qu. Ah my good Lord, what haue I seene to night? + King. What Gertrude? How do's Hamlet? + Qu. Mad as the Seas, and winde, when both contend +Which is the Mightier, in his lawlesse fit +Behinde the Arras, hearing something stirre, +He whips his Rapier out, and cries a Rat, a Rat, +And in his brainish apprehension killes +The vnseene good old man + + King. Oh heauy deed: +It had bin so with vs had we beene there: +His Liberty is full of threats to all, +To you your selfe, to vs, to euery one. +Alas, how shall this bloody deede be answered? +It will be laide to vs, whose prouidence +Should haue kept short, restrain'd, and out of haunt, +This mad yong man. But so much was our loue, +We would not vnderstand what was most fit, +But like the Owner of a foule disease, +To keepe it from divulging, let's it feede +Euen on the pith of life. Where is he gone? + Qu. To draw apart the body he hath kild, +O're whom his very madnesse like some Oare +Among a Minerall of Mettels base +Shewes it selfe pure. He weepes for what is done + + King. Oh Gertrude, come away: +The Sun no sooner shall the Mountaines touch, +But we will ship him hence, and this vilde deed, +We must with all our Maiesty and Skill +Both countenance, and excuse. +Enter Ros. & Guild. + +Ho Guildenstern: +Friends both go ioyne you with some further ayde: +Hamlet in madnesse hath Polonius slaine, +And from his Mother Clossets hath he drag'd him. +Go seeke him out, speake faire, and bring the body +Into the Chappell. I pray you hast in this. +Exit Gent. + +Come Gertrude, wee'l call vp our wisest friends, +To let them know both what we meane to do, +And what's vntimely done. Oh come away, +My soule is full of discord and dismay. + +Exeunt. + +Enter Hamlet. + + Ham. Safely stowed + + Gentlemen within. Hamlet, Lord Hamlet + + Ham. What noise? Who cals on Hamlet? +Oh heere they come. +Enter Ros. and Guildensterne. + + Ro. What haue you done my Lord with the dead body? + Ham. Compounded it with dust, whereto 'tis Kinne + + Rosin. Tell vs where 'tis, that we may take it thence, +And beare it to the Chappell + + Ham. Do not beleeue it + + Rosin. Beleeue what? + Ham. That I can keepe your counsell, and not mine +owne. Besides, to be demanded of a Spundge, what replication +should be made by the Sonne of a King + + Rosin. Take you me for a Spundge, my Lord? + Ham. I sir, that sokes vp the Kings Countenance, his +Rewards, his Authorities (but such Officers do the King +best seruice in the end. He keepes them like an Ape in +the corner of his iaw, first mouth'd to be last swallowed, +when he needes what you haue glean'd, it is but squeezing +you, and Spundge you shall be dry againe + + Rosin. I vnderstand you not my Lord + + Ham. I am glad of it: a knauish speech sleepes in a +foolish eare + + Rosin. My Lord, you must tell vs where the body is, +and go with vs to the King + + Ham. The body is with the King, but the King is not +with the body. The King, is a thing- + Guild. A thing my Lord? + Ham. Of nothing: bring me to him, hide Fox, and all +after. + +Exeunt. + +Enter King. + + King. I haue sent to seeke him, and to find the bodie: +How dangerous is it that this man goes loose: +Yet must not we put the strong Law on him: +Hee's loued of the distracted multitude, +Who like not in their iudgement, but their eyes: +And where 'tis so, th' Offenders scourge is weigh'd +But neerer the offence: to beare all smooth, and euen, +This sodaine sending him away, must seeme +Deliberate pause, diseases desperate growne, +By desperate appliance are releeued, +Or not at all. +Enter Rosincrane. + +How now? What hath befalne? + Rosin. Where the dead body is bestow'd my Lord, +We cannot get from him + + King. But where is he? + Rosin. Without my Lord, guarded to know your +pleasure + + King. Bring him before vs + + Rosin. Hoa, Guildensterne? Bring in my Lord. +Enter Hamlet and Guildensterne. + + King. Now Hamlet, where's Polonius? + Ham. At Supper + + King. At Supper? Where? + Ham. Not where he eats, but where he is eaten, a certaine +conuocation of wormes are e'ne at him. Your worm +is your onely Emperor for diet. We fat all creatures else +to fat vs, and we fat our selfe for Magots. Your fat King, +and your leane Begger is but variable seruice to dishes, +but to one Table that's the end + + King. What dost thou meane by this? + Ham. Nothing but to shew you how a King may go +a Progresse through the guts of a Begger + + King. Where is Polonius + + Ham. In heauen, send thither to see. If your Messenger +finde him not there, seeke him i'th other place your +selfe: but indeed, if you finde him not this moneth, you +shall nose him as you go vp the staires into the Lobby + + King. Go seeke him there + + Ham. He will stay till ye come + + K. Hamlet, this deed of thine, for thine especial safety +Which we do tender, as we deerely greeue +For that which thou hast done, must send thee hence +With fierie Quicknesse. Therefore prepare thy selfe, +The Barke is readie, and the winde at helpe, +Th' Associates tend, and euery thing at bent +For England + + Ham. For England? + King. I Hamlet + + Ham. Good + + King. So is it, if thou knew'st our purposes + + Ham. I see a Cherube that see's him: but come, for +England. Farewell deere Mother + + King. Thy louing Father Hamlet + + Hamlet. My Mother: Father and Mother is man and +wife: man & wife is one flesh, and so my mother. Come, +for England. + +Exit + + King. Follow him at foote, +Tempt him with speed aboord: +Delay it not, Ile haue him hence to night. +Away, for euery thing is Seal'd and done +That else leanes on th' Affaire, pray you make hast. +And England, if my loue thou holdst at ought, +As my great power thereof may giue thee sense, +Since yet thy Cicatrice lookes raw and red +After the Danish Sword, and thy free awe +Payes homage to vs; thou maist not coldly set +Our Soueraigne Processe, which imports at full +By Letters coniuring to that effect +The present death of Hamlet. Do it England, +For like the Hecticke in my blood he rages, +And thou must cure me: Till I know 'tis done, +How ere my happes, my ioyes were ne're begun. + +Exit + +Enter Fortinbras with an Armie. + + For. Go Captaine, from me greet the Danish King, +Tell him that by his license, Fortinbras +Claimes the conueyance of a promis'd March +Ouer his Kingdome.

Go safely on. +Enter. + +Enter Queene and Horatio. + + Qu. I will not speake with her + + Hor. She is importunate, indeed distract, her moode +will needs be pittied + + Qu. What would she haue? + Hor. She speakes much of her Father; saies she heares +There's trickes i'th' world, and hems, and beats her heart, +Spurnes enuiously at Strawes, speakes things in doubt, +That carry but halfe sense: Her speech is nothing, +Yet the vnshaped vse of it doth moue +The hearers to Collection; they ayme at it, +And botch the words vp fit to their owne thoughts, +Which as her winkes, and nods, and gestures yeeld them, +Indeed would make one thinke there would be thought, +Though nothing sure, yet much vnhappily + + Qu. 'Twere good she were spoken with, +For she may strew dangerous coniectures +In ill breeding minds. Let her come in. +To my sicke soule (as sinnes true Nature is) +Each toy seemes Prologue, to some great amisse, +So full of Artlesse iealousie is guilt, +It spill's it selfe, in fearing to be spilt. +Enter Ophelia distracted. + + Ophe. Where is the beauteous Maiesty of Denmark + + Qu. How now Ophelia? + Ophe. How should I your true loue know from another one? +By his Cockle hat and staffe, and his Sandal shoone + + Qu. Alas sweet Lady: what imports this Song? + Ophe. Say you? Nay pray you marke. +He is dead and gone Lady, he is dead and gone, +At his head a grasse-greene Turfe, at his heeles a stone. +Enter King. + + Qu. Nay but Ophelia + + Ophe. Pray you marke. +White his Shrow'd as the Mountaine Snow + + Qu. Alas, looke heere my Lord + + Ophe. Larded with sweet Flowers: +Which bewept to the graue did not go, +With true-loue showres + + King. How do ye, pretty Lady? + Ophe. Well, God dil'd you. They say the Owle was +a Bakers daughter.

Pray you let's haue no words of this: but when +they aske you what it meanes, say you this: +To morrow is S[aint]. Valentines day, all in the morning betime, +And I a Maid at your Window, to be your Valentine. +Then vp he rose, & don'd his clothes, & dupt the chamber dore, +Let in the Maid, that out a Maid, neuer departed more + + King. Pretty Ophelia + + Ophe. Indeed la? without an oath Ile make an end ont. +By gis, and by S[aint].

How long hath she bin thus? + Ophe. I hope all will be well. We must bee patient, +but I cannot choose but weepe, to thinke they should +lay him i'th' cold ground: My brother shall knowe of it, +and so I thanke you for your good counsell.

Follow her close, +Giue her good watch I pray you: +Oh this is the poyson of deepe greefe, it springs +All from her Fathers death. Oh Gertrude, Gertrude, +When sorrowes comes, they come not single spies, +But in Battalians. First, her Father slaine, +Next your Sonne gone, and he most violent Author +Of his owne iust remoue: the people muddied, +Thicke and vnwholsome in their thoughts, and whispers +For good Polonius death; and we haue done but greenly +In hugger mugger to interre him. Poore Ophelia +Diuided from her selfe, and her faire Iudgement, +Without the which we are Pictures, or meere Beasts. +Last, and as much containing as all these, +Her Brother is in secret come from France, +Keepes on his wonder, keepes himselfe in clouds, +And wants not Buzzers to infect his eare +With pestilent Speeches of his Fathers death, +Where in necessitie of matter Beggard, +Will nothing sticke our persons to Arraigne +In eare and eare. O my deere Gertrude, this, +Like to a murdering Peece in many places, +Giues me superfluous death. + +A Noise within. + +Enter a Messenger. + + Qu. Alacke, what noyse is this? + King. Where are my Switzers? +Let them guard the doore. What is the matter? + Mes. Saue your selfe, my Lord. +The Ocean (ouer-peering of his List) +Eates not the Flats with more impittious haste +Then young Laertes, in a Riotous head, +Ore-beares your Officers, the rabble call him Lord, +And as the world were now but to begin, +Antiquity forgot, Custome not knowne, +The Ratifiers and props of euery word, +They cry choose we? Laertes shall be King, +Caps, hands, and tongues, applaud it to the clouds, +Laertes shall be King, Laertes King + + Qu. How cheerefully on the false Traile they cry, +Oh this is Counter you false Danish Dogges. + +Noise within. Enter Laertes. + + King. The doores are broke + + Laer. Where is the King, sirs?

Calmely good Laertes + + Laer. That drop of blood, that calmes +Proclaimes me Bastard: +Cries Cuckold to my Father, brands the Harlot +Euen heere betweene the chaste vnsmirched brow +Of my true Mother + + King. What is the cause Laertes, +That thy Rebellion lookes so Gyant-like? +Let him go Gertrude: Do not feare our person: +There's such Diuinity doth hedge a King, +That Treason can but peepe to what it would, +Acts little of his will. Tell me Laertes, +Why thou art thus Incenst? Let him go Gertrude. +Speake man + + Laer. Where's my Father? + King. Dead + + Qu. But not by him + + King. Let him demand his fill + + Laer. How came he dead? Ile not be Iuggel'd with. +To hell Allegeance: Vowes, to the blackest diuell. +Conscience and Grace, to the profoundest Pit. +I dare Damnation: to this point I stand, +That both the worlds I giue to negligence, +Let come what comes: onely Ile be reueng'd +Most throughly for my Father + + King. Who shall stay you? + Laer. My Will, not all the world, +And for my meanes, Ile husband them so well, +They shall go farre with little + + King. Good Laertes: +If you desire to know the certaintie +Of your deere Fathers death, if writ in your reuenge, +That Soop-stake you will draw both Friend and Foe, +Winner and Looser + + Laer. None but his Enemies + + King. Will you know them then + + La. To his good Friends, thus wide Ile ope my Armes: +And like the kinde Life-rend'ring Politician, +Repast them with my blood + + King. Why now you speake +Like a good Childe, and a true Gentleman. +That I am guiltlesse of your Fathers death, +And am most sensible in greefe for it, +It shall as leuell to your Iudgement pierce +As day do's to your eye. + +A noise within. Let her come in. + +Enter Ophelia. + + Laer. How now? what noise is that? +Oh heate drie vp my Braines, teares seuen times salt, +Burne out the Sence and Vertue of mine eye. +By Heauen, thy madnesse shall be payed by waight, +Till our Scale turnes the beame. Oh Rose of May, +Deere Maid, kinde Sister, sweet Ophelia: +Oh Heauens, is't possible, a yong Maids wits, +Should be as mortall as an old mans life? +Nature is fine in Loue, and where 'tis fine, +It sends some precious instance of it selfe +After the thing it loues + + Ophe. They bore him bare fac'd on the Beer, +Hey non nony, nony, hey nony: +And on his graue raines many a teare, +Fare you well my Doue + + Laer. Had'st thou thy wits, and did'st perswade Reuenge, +it could not moue thus + + Ophe. You must sing downe a-downe, and you call +him a-downe-a. Oh, how the wheele becomes it? It is +the false Steward that stole his masters daughter + + Laer. This nothings more then matter + + Ophe. There's Rosemary, that's for Remembraunce. +Pray loue remember: and there is Paconcies, that's for +Thoughts + + Laer. A document in madnesse, thoughts & remembrance +fitted + + Ophe. There's Fennell for you, and Columbines: ther's +Rew for you, and heere's some for me. Wee may call it +Herbe-Grace a Sundaies: Oh you must weare your Rew +with a difference. There's a Daysie, I would giue you +some Violets, but they wither'd all when my Father dyed: +They say, he made a good end; +For bonny sweet Robin is all my ioy + + Laer. Thought, and Affliction, Passion, Hell it selfe: +She turnes to Fauour, and to prettinesse + + Ophe. And will he not come againe, +And will he not come againe: +No, no, he is dead, go to thy Death-bed, +He neuer wil come againe. +His Beard as white as Snow, +All Flaxen was his Pole: +He is gone, he is gone, and we cast away mone, +Gramercy on his Soule. +And of all Christian Soules, I pray God. +God buy ye. + +Exeunt. Ophelia + + Laer. Do you see this, you Gods? + King. Laertes, I must common with your greefe, +Or you deny me right: go but apart, +Make choice of whom your wisest Friends you will, +And they shall heare and iudge 'twixt you and me; +If by direct or by Colaterall hand +They finde vs touch'd, we will our Kingdome giue, +Our Crowne, our Life, and all that we call Ours +To you in satisfaction. But if not, +Be you content to lend your patience to vs, +And we shall ioyntly labour with your soule +To giue it due content + + Laer. Let this be so: +His meanes of death, his obscure buriall; +No Trophee, Sword, nor Hatchment o're his bones, +No Noble rite, nor formall ostentation, +Cry to be heard, as 'twere from Heauen to Earth, +That I must call in question + + King. So you shall: +And where th' offence is, let the great Axe fall. +I pray you go with me. + +Exeunt. + +Enter Horatio, with an Attendant. + + Hora. What are they that would speake with me? + Ser. Saylors sir, they say they haue Letters for you + + Hor. Let them come in, +I do not know from what part of the world +I should be greeted, if not from Lord Hamlet. +Enter Saylor. + + Say. God blesse you Sir + + Hor. Let him blesse thee too + + Say. Hee shall Sir, and't please him. There's a Letter +for you Sir: It comes from th' Ambassadours that was +bound for England, if your name be Horatio, as I am let +to know it is. + +Reads the Letter. + +Horatio, When thou shalt haue ouerlook'd this, giue these +Fellowes some meanes to the King: They haue Letters +for him. Ere we were two dayes old at Sea, a Pyrate of very +Warlicke appointment gaue vs Chace. Finding our selues too +slow of Saile, we put on a compelled Valour. In the Grapple, I +boorded them: On the instant they got cleare of our Shippe, so +I alone became their Prisoner. They haue dealt with mee, like +Theeues of Mercy, but they knew what they did. I am to doe +a good turne for them. Let the King haue the Letters I haue +sent, and repaire thou to me with as much hast as thou wouldest +flye death. I haue words to speake in your eare, will make thee +dumbe, yet are they much too light for the bore of the Matter. +These good Fellowes will bring thee where I am. Rosincrance +and Guildensterne, hold their course for England. Of them +I haue much to tell thee, Farewell. +He that thou knowest thine, +Hamlet. +Come, I will giue you way for these your Letters, +And do't the speedier, that you may direct me +To him from whom you brought them. +Enter. + +Enter King and Laertes. + + King. Now must your conscience my acquittance seal, +And you must put me in your heart for Friend, +Sith you haue heard, and with a knowing eare, +That he which hath your Noble Father slaine, +Pursued my life + + Laer. It well appeares. But tell me, +Why you proceeded not against these feates, +So crimefull, and so Capitall in Nature, +As by your Safety, Wisedome, all things else, +You mainly were stirr'd vp? + King. O for two speciall Reasons, +Which may to you (perhaps) seeme much vnsinnowed, +And yet to me they are strong. The Queen his Mother, +Liues almost by his lookes: and for my selfe, +My Vertue or my Plague, be it either which, +She's so coniunctiue to my life, and soule; +That as the Starre moues not but in his Sphere, +I could not but by her. The other Motiue, +Why to a publike count I might not go, +Is the great loue the generall gender beare him, +Who dipping all his Faults in their affection, +Would like the Spring that turneth Wood to Stone, +Conuert his Gyues to Graces. So that my Arrowes +Too slightly timbred for so loud a Winde, +Would haue reuerted to my Bow againe, +And not where I had arm'd them + + Laer. And so haue I a Noble Father lost, +A Sister driuen into desperate tearmes, +Who was (if praises may go backe againe) +Stood Challenger on mount of all the Age +For her perfections. But my reuenge will come + + King. Breake not your sleepes for that, +You must not thinke +That we are made of stuffe, so flat, and dull, +That we can let our Beard be shooke with danger, +And thinke it pastime. You shortly shall heare more, +I lou'd your Father, and we loue our Selfe, +And that I hope will teach you to imagine- +Enter a Messenger. + +How now? What Newes? + Mes. Letters my Lord from Hamlet, This to your +Maiesty: this to the Queene + + King. From Hamlet? Who brought them? + Mes. Saylors my Lord they say, I saw them not: +They were giuen me by Claudio, he receiu'd them + + King. Laertes you shall heare them: +Leaue vs. + +Exit Messenger + +High and Mighty, you shall know I am set naked on your +Kingdome. To morrow shall I begge leaue to see your Kingly +Eyes. When I shall (first asking your Pardon thereunto) recount +th' Occasions of my sodaine, and more strange returne. +Hamlet. +What should this meane? Are all the rest come backe? +Or is it some abuse? Or no such thing? + Laer. Know you the hand? + Kin. 'Tis Hamlets Character, naked and in a Postscript +here he sayes alone: Can you aduise me? + Laer. I'm lost in it my Lord; but let him come, +It warmes the very sicknesse in my heart, +That I shall liue and tell him to his teeth; +Thus diddest thou + + Kin. If it be so Laertes, as how should it be so: +How otherwise will you be rul'd by me? + Laer. If so you'l not o'rerule me to a peace + + Kin. To thine owne peace: if he be now return'd, +As checking at his Voyage, and that he meanes +No more to vndertake it; I will worke him +To an exployt now ripe in my Deuice, +Vnder the which he shall not choose but fall; +And for his death no winde of blame shall breath, +But euen his Mother shall vncharge the practice, +And call it accident: Some two Monthes hence +Here was a Gentleman of Normandy, +I'ue seene my selfe, and seru'd against the French, +And they ran well on Horsebacke; but this Gallant +Had witchcraft in't; he grew into his Seat, +And to such wondrous doing brought his Horse, +As had he beene encorps't and demy-Natur'd +With the braue Beast, so farre he past my thought, +That I in forgery of shapes and trickes, +Come short of what he did + + Laer. A Norman was't? + Kin. A Norman + + Laer. Vpon my life Lamound + + Kin. The very same + + Laer. I know him well, he is the Brooch indeed, +And Iemme of all our Nation + + Kin. Hee mad confession of you, +And gaue you such a Masterly report, +For Art and exercise in your defence; +And for your Rapier most especiall, +That he cryed out, t'would be a sight indeed, +If one could match you Sir. This report of his +Did Hamlet so envenom with his Enuy, +That he could nothing doe but wish and begge, +Your sodaine comming ore to play with him; +Now out of this + + Laer. Why out of this, my Lord? + Kin. Laertes was your Father deare to you? +Or are you like the painting of a sorrow, +A face without a heart? + Laer. Why aske you this? + Kin. Not that I thinke you did not loue your Father, +But that I know Loue is begun by Time: +And that I see in passages of proofe, +Time qualifies the sparke and fire of it: +Hamlet comes backe: what would you vndertake, +To show your selfe your Fathers sonne indeed, +More then in words? + Laer. To cut his throat i'th' Church + + Kin. No place indeed should murder Sancturize; +Reuenge should haue no bounds: but good Laertes +Will you doe this, keepe close within your Chamber, +Hamlet return'd, shall know you are come home: +Wee'l put on those shall praise your excellence, +And set a double varnish on the fame +The Frenchman gaue you, bring you in fine together, +And wager on your heads, he being remisse, +Most generous, and free from all contriuing, +Will not peruse the Foiles? So that with ease, +Or with a little shuffling, you may choose +A Sword vnbaited, and in a passe of practice, +Requit him for your Father + + Laer. I will doo't. +And for that purpose Ile annoint my Sword: +I bought an Vnction of a Mountebanke +So mortall, I but dipt a knife in it, +Where it drawes blood, no Cataplasme so rare, +Collected from all Simples that haue Vertue +Vnder the Moone, can saue the thing from death, +That is but scratcht withall: Ile touch my point, +With this contagion, that if I gall him slightly, +It may be death + + Kin. Let's further thinke of this, +Weigh what conuenience both of time and meanes +May fit vs to our shape, if this should faile; +And that our drift looke through our bad performance, +'Twere better not assaid; therefore this Proiect +Should haue a backe or second, that might hold, +If this should blast in proofe: Soft, let me see +Wee'l make a solemne wager on your commings, +I ha't: when in your motion you are hot and dry, +As make your bowts more violent to the end, +And that he cals for drinke; Ile haue prepar'd him +A Challice for the nonce; whereon but sipping, +If he by chance escape your venom'd stuck, +Our purpose may hold there; how sweet Queene. +Enter Queene. + + Queen. One woe doth tread vpon anothers heele, +So fast they'l follow: your Sister's drown'd Laertes + + Laer. Drown'd! O where? + Queen. There is a Willow growes aslant a Brooke, +That shewes his hore leaues in the glassie streame: +There with fantasticke Garlands did she come, +Of Crow-flowers, Nettles, Daysies, and long Purples, +That liberall Shepheards giue a grosser name; +But our cold Maids doe Dead Mens Fingers call them: +There on the pendant boughes, her Coronet weeds +Clambring to hang; an enuious sliuer broke, +When downe the weedy Trophies, and her selfe, +Fell in the weeping Brooke, her cloathes spred wide, +And Mermaid-like, a while they bore her vp, +Which time she chaunted snatches of old tunes, +As one incapable of her owne distresse, +Or like a creature Natiue, and indued +Vnto that Element: but long it could not be, +Till that her garments, heauy with her drinke, +Pul'd the poore wretch from her melodious buy, +To muddy death + + Laer. Alas then, is she drown'd? + Queen. Drown'd, drown'd + + Laer. Too much of water hast thou poore Ophelia, +And therefore I forbid my teares: but yet +It is our tricke, Nature her custome holds, +Let shame say what it will; when these are gone +The woman will be out: Adue my Lord, +I haue a speech of fire, that faine would blaze, +But that this folly doubts it. +Enter. + + Kin. Let's follow, Gertrude: +How much I had to doe to calme his rage? +Now feare I this will giue it start againe; +Therefore let's follow. + +Exeunt. + +Enter two Clownes. + + Clown. Is she to bee buried in Christian buriall, that +wilfully seekes her owne saluation? + Other. I tell thee she is, and therefore make her Graue +straight, the Crowner hath sate on her, and finds it Christian +buriall + + Clo. How can that be, vnlesse she drowned her selfe in +her owne defence? + Other. Why 'tis found so + + Clo. It must be Se offendendo, it cannot bee else: for +heere lies the point; If I drowne my selfe wittingly, it argues +an Act: and an Act hath three branches. It is an +Act to doe and to performe; argall she drown'd her selfe +wittingly + + Other. Nay but heare you Goodman Deluer + + Clown. Giue me leaue; heere lies the water; good: +heere stands the man; good: If the man goe to this water +and drowne himselfe; it is will he nill he, he goes; +marke you that? But if the water come to him & drowne +him; hee drownes not himselfe. Argall, hee that is not +guilty of his owne death, shortens not his owne life + + Other. But is this law? + Clo. I marry is't, Crowners Quest Law + + Other. Will you ha the truth on't: if this had not +beene a Gentlewoman, shee should haue beene buried +out of Christian Buriall + + Clo. Why there thou say'st. And the more pitty that +great folke should haue countenance in this world to +drowne or hang themselues, more then their euen Christian. +Come, my Spade; there is no ancient Gentlemen, +but Gardiners, Ditchers and Graue-makers; they hold vp +Adams Profession + + Other. Was he a Gentleman? + Clo. He was the first that euer bore Armes + + Other. Why he had none + + Clo. What, ar't a Heathen? how doth thou vnderstand +the Scripture? the Scripture sayes Adam dig'd; +could hee digge without Armes? Ile put another question +to thee; if thou answerest me not to the purpose, confesse +thy selfe- + Other. Go too + + Clo. What is he that builds stronger then either the +Mason, the Shipwright, or the Carpenter? + Other. The Gallowes maker; for that Frame outliues a +thousand Tenants + + Clo. I like thy wit well in good faith, the Gallowes +does well; but how does it well? it does well to those +that doe ill: now, thou dost ill to say the Gallowes is +built stronger then the Church: Argall, the Gallowes +may doe well to thee. Too't againe, Come + + Other. Who builds stronger then a Mason, a Shipwright, +or a Carpenter? + Clo. I, tell me that, and vnyoake + + Other. Marry, now I can tell + + Clo. Too't + + Other. Masse, I cannot tell. +Enter Hamlet and Horatio a farre off. + + Clo. Cudgell thy braines no more about it; for your +dull Asse will not mend his pace with beating; and when +you are ask't this question next, say a Graue-maker: the +Houses that he makes, lasts till Doomesday: go, get thee +to Yaughan, fetch me a stoupe of Liquor. + +Sings. + +In youth when I did loue, did loue, +me thought it was very sweete: +To contract O the time for a my behoue, +O me thought there was nothing meete + + Ham. Ha's this fellow no feeling of his businesse, that +he sings at Graue-making? + Hor. Custome hath made it in him a property of easinesse + + Ham. 'Tis ee'n so; the hand of little Imployment hath +the daintier sense + + Clowne sings. But Age with his stealing steps +hath caught me in his clutch: +And hath shipped me intill the Land, +as if I had neuer beene such + + Ham. That Scull had a tongue in it, and could sing +once: how the knaue iowles it to th' grownd, as if it +were Caines Iaw-bone, that did the first murther: It +might be the Pate of a Polititian which this Asse o're Offices: +one that could circumuent God, might it not? + Hor. It might, my Lord + + Ham. Or of a Courtier, which could say, Good Morrow +sweet Lord: how dost thou, good Lord? this +might be my Lord such a one, that prais'd my Lord such +a ones Horse, when he meant to begge it; might it not? + Hor. I, my Lord + + Ham. Why ee'n so: and now my Lady Wormes, +Chaplesse, and knockt about the Mazard with a Sextons +Spade; heere's fine Reuolution, if wee had the tricke to +see't. Did these bones cost no more the breeding, but +to play at Loggets with 'em? mine ake to thinke +on't + + Clowne sings. A Pickhaxe and a Spade, a Spade, +for and a shrowding-Sheete: +O a Pit of Clay for to be made, +for such a Guest is meete + + Ham. There's another: why might not that bee the +Scull of a Lawyer? where be his Quiddits now? his +Quillets? his Cases? his Tenures, and his Tricks? why +doe's he suffer this rude knaue now to knocke him about +the Sconce with a dirty Shouell, and will not tell him of +his Action of Battery? hum. This fellow might be in's +time a great buyer of Land, with his Statutes, his Recognizances, +his Fines, his double Vouchers, his Recoueries: +Is this the fine of his Fines, and the recouery of his Recoueries, +to haue his fine Pate full of fine Dirt? will his +Vouchers vouch him no more of his Purchases, and double +ones too, then the length and breadth of a paire of +Indentures? the very Conueyances of his Lands will +hardly lye in this Boxe; and must the Inheritor himselfe +haue no more? ha? + Hor. Not a iot more, my Lord + + Ham. Is not Parchment made of Sheep-skinnes? + Hor. I my Lord, and of Calue-skinnes too + + Ham. They are Sheepe and Calues that seek out assurance +in that. I will speake to this fellow: whose Graue's +this Sir? + Clo. Mine Sir: +O a Pit of Clay for to be made, +for such a Guest is meete + + Ham. I thinke it be thine indeed: for thou liest in't + + Clo. You lye out on't Sir, and therefore it is not yours: +for my part, I doe not lye in't; and yet it is mine + + Ham. Thou dost lye in't, to be in't and say 'tis thine: +'tis for the dead, not for the quicke, therefore thou +lyest + + Clo. 'Tis a quicke lye Sir, 'twill away againe from me +to you + + Ham. What man dost thou digge it for? + Clo. For no man Sir + + Ham. What woman then? + Clo. For none neither + + Ham. Who is to be buried in't? + Clo. One that was a woman Sir; but rest her Soule, +shee's dead + + Ham. How absolute the knaue is? wee must speake +by the Carde, or equiuocation will vndoe vs: by the +Lord Horatio, these three yeares I haue taken note of it, +the Age is growne so picked, that the toe of the Pesant +comes so neere the heeles of our Courtier, hee galls his +Kibe. How long hast thou been a Graue-maker? + Clo. Of all the dayes i'th' yeare, I came too't that day +that our last King Hamlet o'recame Fortinbras + + Ham. How long is that since? + Clo. Cannot you tell that? euery foole can tell that: +It was the very day, that young Hamlet was borne, hee +that was mad, and sent into England + + Ham. I marry, why was he sent into England? + Clo. Why, because he was mad; hee shall recouer his +wits there; or if he do not, it's no great matter there + + Ham. Why? + Clo. 'Twill not be seene in him, there the men are as +mad as he + + Ham. How came he mad? + Clo. Very strangely they say + + Ham. How strangely? + Clo. Faith e'ene with loosing his wits + + Ham. Vpon what ground? + Clo. Why heere in Denmarke: I haue bin sixeteene +heere, man and Boy thirty yeares + + Ham. How long will a man lie i'th' earth ere he rot? + Clo. Ifaith, if he be not rotten before he die (as we haue +many pocky Coarses now adaies, that will scarce hold +the laying in) he will last you some eight yeare, or nine +yeare. A Tanner will last you nine yeare + + Ham. Why he, more then another? + Clo. Why sir, his hide is so tan'd with his Trade, that +he will keepe out water a great while. And your water, +is a sore Decayer of your horson dead body. Heres a Scull +now: this Scul, has laine in the earth three & twenty years + + Ham. Whose was it? + Clo. A whoreson mad Fellowes it was; +Whose doe you thinke it was? + Ham. Nay, I know not + + Clo. A pestilence on him for a mad Rogue, a pour'd a +Flaggon of Renish on my head once. This same Scull +Sir, this same Scull sir, was Yoricks Scull, the Kings Iester + + Ham. This? + Clo. E'ene that + + Ham. Let me see. Alas poore Yorick, I knew him Horatio, +a fellow of infinite Iest; of most excellent fancy, he +hath borne me on his backe a thousand times: And how +abhorred my Imagination is, my gorge rises at it. Heere +hung those lipps, that I haue kist I know not how oft. +Where be your Iibes now? Your Gambals? Your +Songs? Your flashes of Merriment that were wont to +set the Table on a Rore? No one now to mock your own +Ieering? Quite chopfalne? Now get you to my Ladies +Chamber, and tell her, let her paint an inch thicke, to this +fauour she must come. Make her laugh at that: prythee +Horatio tell me one thing + + Hor. What's that my Lord? + Ham. Dost thou thinke Alexander lookt o'this fashion +i'th' earth? + Hor. E'ene so + + Ham. And smelt so? Puh + + Hor. E'ene so, my Lord + + Ham. To what base vses we may returne Horatio. +Why may not Imagination trace the Noble dust of Alexander, +till he find it stopping a bunghole + + Hor. 'Twere to consider: to curiously to consider so + + Ham. No faith, not a iot. But to follow him thether +with modestie enough, & likeliehood to lead it; as thus. +Alexander died: Alexander was buried: Alexander returneth +into dust; the dust is earth; of earth we make +Lome, and why of that Lome (whereto he was conuerted) +might they not stopp a Beere-barrell? +Imperiall Caesar, dead and turn'd to clay, +Might stop a hole to keepe the winde away. +Oh, that that earth, which kept the world in awe, +Should patch a Wall, t' expell the winters flaw. +But soft, but soft, aside; heere comes the King. +Enter King, Queene, Laertes, and a Coffin, with Lords attendant. + +The Queene, the Courtiers. Who is that they follow, +And with such maimed rites? This doth betoken, +The Coarse they follow, did with disperate hand, +Fore do it owne life; 'twas some Estate. +Couch we a while, and mark + + Laer. What Cerimony else? + Ham. That is Laertes, a very Noble youth: Marke + + Laer. What Cerimony else? + Priest. Her Obsequies haue bin as farre inlarg'd. +As we haue warrantie, her death was doubtfull, +And but that great Command, o're-swaies the order, +She should in ground vnsanctified haue lodg'd, +Till the last Trumpet. For charitable praier, +Shardes, Flints, and Peebles, should be throwne on her: +Yet heere she is allowed her Virgin Rites, +Her Maiden strewments, and the bringing home +Of Bell and Buriall + + Laer. Must there no more be done ? + Priest. No more be done: +We should prophane the seruice of the dead, +To sing sage Requiem, and such rest to her +As to peace-parted Soules + + Laer. Lay her i'th' earth, +And from her faire and vnpolluted flesh, +May Violets spring. I tell thee (churlish Priest) +A Ministring Angell shall my Sister be, +When thou liest howling? + Ham. What, the faire Ophelia? + Queene. Sweets, to the sweet farewell. +I hop'd thou should'st haue bin my Hamlets wife: +I thought thy Bride-bed to haue deckt (sweet Maid) +And not t'haue strew'd thy Graue + + Laer. Oh terrible woer, +Fall ten times trebble, on that cursed head +Whose wicked deed, thy most Ingenious sence +Depriu'd thee of. Hold off the earth a while, +Till I haue caught her once more in mine armes: + +Leaps in the graue. + +Now pile your dust, vpon the quicke, and dead, +Till of this flat a Mountaine you haue made, +To o're top old Pelion, or the skyish head +Of blew Olympus + + Ham. What is he, whose griefes +Beares such an Emphasis? whose phrase of Sorrow +Coniure the wandring Starres, and makes them stand +Like wonder-wounded hearers? This is I, +Hamlet the Dane + + Laer. The deuill take thy soule + + Ham. Thou prai'st not well, +I prythee take thy fingers from my throat; +Sir though I am not Spleenatiue, and rash, +Yet haue I something in me dangerous, +Which let thy wisenesse feare. Away thy hand + + King. Pluck them asunder + + Qu. Hamlet, Hamlet + + Gen. Good my Lord be quiet + + Ham. Why I will fight with him vppon this Theme. +Vntill my eielids will no longer wag + + Qu. Oh my Sonne, what Theame? + Ham. I lou'd Ophelia; fortie thousand Brothers +Could not (with all there quantitie of Loue) +Make vp my summe. What wilt thou do for her? + King. Oh he is mad Laertes, + Qu. For loue of God forbeare him + + Ham. Come show me what thou'lt doe. +Woo't weepe? Woo't fight? Woo't teare thy selfe? +Woo't drinke vp Esile, eate a Crocodile? +Ile doo't. Dost thou come heere to whine; +To outface me with leaping in her Graue? +Be buried quicke with her, and so will I. +And if thou prate of Mountaines; let them throw +Millions of Akers on vs; till our ground +Sindging his pate against the burning Zone, +Make Ossa like a wart. Nay, and thou'lt mouth, +Ile rant as well as thou + + Kin. This is meere Madnesse: +And thus awhile the fit will worke on him: +Anon as patient as the female Doue, +When that her Golden Cuplet are disclos'd; +His silence will sit drooping + + Ham. Heare you Sir: +What is the reason that you vse me thus? +I lou'd you euer; but it is no matter: +Let Hercules himselfe doe what he may, +The Cat will Mew, and Dogge will haue his day. +Enter. + + Kin. I pray you good Horatio wait vpon him, +Strengthen your patience in our last nights speech, +Wee'l put the matter to the present push: +Good Gertrude set some watch ouer your Sonne, +This Graue shall haue a liuing Monument: +An houre of quiet shortly shall we see; +Till then, in patience our proceeding be. + +Exeunt. + +Enter Hamlet and Horatio + + Ham. So much for this Sir; now let me see the other, +You doe remember all the Circumstance + + Hor. Remember it my Lord? + Ham. Sir, in my heart there was a kinde of fighting, +That would not let me sleepe; me thought I lay +Worse then the mutines in the Bilboes, rashly, +(And praise be rashnesse for it) let vs know, +Our indiscretion sometimes serues vs well, +When our deare plots do paule, and that should teach vs, +There's a Diuinity that shapes our ends, +Rough-hew them how we will + + Hor. That is most certaine + + Ham. Vp from my Cabin +My sea-gowne scarft about me in the darke, +Grop'd I to finde out them; had my desire, +Finger'd their Packet, and in fine, withdrew +To mine owne roome againe, making so bold, +(My feares forgetting manners) to vnseale +Their grand Commission, where I found Horatio, +Oh royall knauery: An exact command, +Larded with many seuerall sorts of reason; +Importing Denmarks health, and Englands too, +With hoo, such Bugges and Goblins in my life, +That on the superuize no leasure bated, +No not to stay the grinding of the Axe, +My head should be struck off + + Hor. Ist possible? + Ham. Here's the Commission, read it at more leysure: +But wilt thou heare me how I did proceed? + Hor. I beseech you + + Ham. Being thus benetted round with Villaines, +Ere I could make a Prologue to my braines, +They had begun the Play. I sate me downe, +Deuis'd a new Commission, wrote it faire, +I once did hold it as our Statists doe, +A basenesse to write faire; and laboured much +How to forget that learning: but Sir now, +It did me Yeomans seriuce: wilt thou know +The effects of what I wrote? + Hor. I, good my Lord + + Ham. An earnest Coniuration from the King, +As England was his faithfull Tributary, +As loue betweene them, as the Palme should flourish, +As Peace should still her wheaten Garland weare, +And stand a Comma 'tweene their amities, +And many such like Assis of great charge, +That on the view and know of these Contents, +Without debatement further, more or lesse, +He should the bearers put to sodaine death, +Not shriuing time allowed + + Hor. How was this seal'd? + Ham. Why, euen in that was Heauen ordinate; +I had my fathers Signet in my Purse, +Which was the Modell of that Danish Seale: +Folded the Writ vp in forme of the other, +Subscrib'd it, gau't th' impression, plac't it safely, +The changeling neuer knowne: Now, the next day +Was our Sea Fight, and what to this was sement, +Thou know'st already + + Hor. So Guildensterne and Rosincrance, go too't + + Ham. Why man, they did make loue to this imployment +They are not neere my Conscience; their debate +Doth by their owne insinuation grow: +'Tis dangerous, when the baser nature comes +Betweene the passe, and fell incensed points +Of mighty opposites + + Hor. Why, what a King is this? + Ham. Does it not, thinkst thee, stand me now vpon +He that hath kil'd my King, and whor'd my Mother, +Popt in betweene th' election and my hopes, +Throwne out his Angle for my proper life, +And with such coozenage; is't not perfect conscience, +To quit him with this arme? And is't not to be damn'd +To let this Canker of our nature come +In further euill + + Hor. It must be shortly knowne to him from England +What is the issue of the businesse there + + Ham. It will be short, +The interim's mine, and a mans life's no more +Then to say one: but I am very sorry good Horatio, +That to Laertes I forgot my selfe; +For by the image of my Cause, I see +The Portraiture of his; Ile count his fauours: +But sure the brauery of his griefe did put me +Into a Towring passion + + Hor. Peace, who comes heere? +Enter young Osricke. + + Osr. Your Lordship is right welcome back to Denmarke + + Ham. I humbly thank you Sir, dost know this waterflie? + Hor. No my good Lord + + Ham. Thy state is the more gracious; for 'tis a vice to +know him: he hath much Land, and fertile; let a Beast +be Lord of Beasts, and his Crib shall stand at the Kings +Messe; 'tis a Chowgh; but as I saw spacious in the possession +of dirt + + Osr. Sweet Lord, if your friendship were at leysure, +I should impart a thing to you from his Maiesty + + Ham. I will receiue it with all diligence of spirit; put +your Bonet to his right vse, 'tis for the head + + Osr. I thanke your Lordship, 'tis very hot + + Ham. No, beleeue mee 'tis very cold, the winde is +Northerly + + Osr. It is indifferent cold my Lord indeed + + Ham. Mee thinkes it is very soultry, and hot for my +Complexion + + Osr. Exceedingly, my Lord, it is very soultry, as 'twere +I cannot tell how: but my Lord, his Maiesty bad me signifie +to you, that he ha's laid a great wager on your head: +Sir, this is the matter + + Ham. I beseech you remember + + Osr. Nay, in good faith, for mine ease in good faith: +Sir, you are not ignorant of what excellence Laertes is at +his weapon + + Ham. What's his weapon? + Osr. Rapier and dagger + + Ham. That's two of his weapons; but well + + Osr. The sir King ha's wag'd with him six Barbary horses, +against the which he impon'd as I take it, sixe French +Rapiers and Poniards, with their assignes, as Girdle, +Hangers or so: three of the Carriages infaith are very +deare to fancy, very responsiue to the hilts, most delicate +carriages, and of very liberall conceit + + Ham. What call you the Carriages? + Osr. The Carriages Sir, are the hangers + + Ham. The phrase would bee more Germaine to the +matter: If we could carry Cannon by our sides; I would +it might be Hangers till then; but on sixe Barbary Horses +against sixe French Swords: their Assignes, and three +liberall conceited Carriages, that's the French but against +the Danish; why is this impon'd as you call it? + Osr. The King Sir, hath laid that in a dozen passes betweene +you and him, hee shall not exceed you three hits; +He hath one twelue for mine, and that would come to +imediate tryall, if your Lordship would vouchsafe the +Answere + + Ham. How if I answere no? + Osr. I meane my Lord, the opposition of your person +in tryall + + Ham. Sir, I will walke heere in the Hall; if it please +his Maiestie, 'tis the breathing time of day with me; let +the Foyles bee brought, the Gentleman willing, and the +King hold his purpose; I will win for him if I can: if +not, Ile gaine nothing but my shame, and the odde hits + + Osr. Shall I redeliuer you ee'n so? + Ham. To this effect Sir, after what flourish your nature +will + + Osr. I commend my duty to your Lordship + + Ham. Yours, yours; hee does well to commend it +himselfe, there are no tongues else for's tongue + + Hor. This Lapwing runs away with the shell on his +head + + Ham. He did Complie with his Dugge before hee +suck't it: thus had he and mine more of the same Beauty +that I know the drossie age dotes on; only got the tune of +the time, and outward habite of encounter, a kinde of +yesty collection, which carries them through & through +the most fond and winnowed opinions; and doe but blow +them to their tryalls: the Bubbles are out + + Hor. You will lose this wager, my Lord + + Ham. I doe not thinke so, since he went into France, +I haue beene in continuall practice; I shall winne at the +oddes: but thou wouldest not thinke how all heere about +my heart: but it is no matter + + Hor. Nay, good my Lord + + Ham. It is but foolery; but it is such a kinde of +gain-giuing as would perhaps trouble a woman + + Hor. If your minde dislike any thing, obey. I will forestall +their repaire hither, and say you are not fit + + Ham. Not a whit, we defie Augury; there's a speciall +Prouidence in the fall of a sparrow. If it be now, 'tis not +to come: if it bee not to come, it will bee now: if it +be not now; yet it will come; the readinesse is all, since no +man ha's ought of what he leaues. What is't to leaue betimes? +Enter King, Queene, Laertes and Lords, with other Attendants with +Foyles, +and Gauntlets, a Table and Flagons of Wine on it. + + Kin. Come Hamlet, come, and take this hand from me + + Ham. Giue me your pardon Sir, I'ue done you wrong, +But pardon't as you are a Gentleman. +This presence knowes, +And you must needs haue heard how I am punisht +With sore distraction? What I haue done +That might your nature honour, and exception +Roughly awake, I heere proclaime was madnesse: +Was't Hamlet wrong'd Laertes? Neuer Hamlet. +If Hamlet from himselfe be tane away: +And when he's not himselfe, do's wrong Laertes, +Then Hamlet does it not, Hamlet denies it: +Who does it then? His Madnesse? If't be so, +Hamlet is of the Faction that is wrong'd, +His madnesse is poore Hamlets Enemy. +Sir, in this Audience, +Let my disclaiming from a purpos'd euill, +Free me so farre in your most generous thoughts, +That I haue shot mine Arrow o're the house, +And hurt my Mother + + Laer. I am satisfied in Nature, +Whose motiue in this case should stirre me most +To my Reuenge. But in my termes of Honor +I stand aloofe, and will no reconcilement, +Till by some elder Masters of knowne Honor, +I haue a voyce, and president of peace +To keepe my name vngorg'd. But till that time, +I do receiue your offer'd loue like loue, +And wil not wrong it + + Ham. I do embrace it freely, +And will this Brothers wager frankely play. +Giue vs the Foyles: Come on + + Laer. Come one for me + + Ham. Ile be your foile Laertes, in mine ignorance, +Your Skill shall like a Starre i'th' darkest night, +Sticke fiery off indeede + + Laer. You mocke me Sir + + Ham. No by this hand + + King. Giue them the Foyles yong Osricke, +Cousen Hamlet, you know the wager + + Ham. Verie well my Lord, +Your Grace hath laide the oddes a'th' weaker side + + King. I do not feare it, +I haue seene you both: +But since he is better'd, we haue therefore oddes + + Laer. This is too heauy, +Let me see another + + Ham. This likes me well, +These Foyles haue all a length. + +Prepare to play. + + Osricke. I my good Lord + + King. Set me the Stopes of wine vpon that Table: +If Hamlet giue the first, or second hit, +Or quit in answer of the third exchange, +Let all the Battlements their Ordinance fire, +The King shal drinke to Hamlets better breath, +And in the Cup an vnion shal he throw +Richer then that, which foure successiue Kings +In Denmarkes Crowne haue worne. +Giue me the Cups, +And let the Kettle to the Trumpets speake, +The Trumpet to the Cannoneer without, +The Cannons to the Heauens, the Heauen to Earth, +Now the King drinkes to Hamlet. Come, begin, +And you the Iudges beare a wary eye + + Ham. Come on sir + + Laer. Come on sir. + +They play. + + Ham. One + + Laer. No + + Ham. Iudgement + + Osr. A hit, a very palpable hit + + Laer. Well: againe + + King. Stay, giue me drinke. +Hamlet, this Pearle is thine, +Here's to thy health. Giue him the cup, + +Trumpets sound, and shot goes off. + + Ham. Ile play this bout first, set by a-while. +Come: Another hit; what say you? + Laer. A touch, a touch, I do confesse + + King. Our Sonne shall win + + Qu. He's fat, and scant of breath. +Heere's a Napkin, rub thy browes, +The Queene Carowses to thy fortune, Hamlet + + Ham. Good Madam + + King. Gertrude, do not drinke + + Qu. I will my Lord; +I pray you pardon me + + King. It is the poyson'd Cup, it is too late + + Ham. I dare not drinke yet Madam, +By and by + + Qu. Come, let me wipe thy face + + Laer. My Lord, Ile hit him now + + King. I do not thinke't + + Laer. And yet 'tis almost 'gainst my conscience + + Ham. Come for the third. +Laertes, you but dally, +I pray you passe with your best violence, +I am affear'd you make a wanton of me + + Laer. Say you so? Come on. + +Play. + + Osr. Nothing neither way + + Laer. Haue at you now. + +In scuffling they change Rapiers. + + King. Part them, they are incens'd + + Ham. Nay come, againe + + Osr. Looke to the Queene there hoa + + Hor. They bleed on both sides. How is't my Lord? + Osr. How is't Laertes? + Laer. Why as a Woodcocke +To mine Sprindge, Osricke, +I am iustly kill'd with mine owne Treacherie + + Ham. How does the Queene? + King. She sounds to see them bleede + + Qu. No, no, the drinke, the drinke. +Oh my deere Hamlet, the drinke, the drinke, +I am poyson'd + + Ham. Oh Villany! How? Let the doore be lock'd. +Treacherie, seeke it out + + Laer. It is heere Hamlet. +Hamlet, thou art slaine, +No Medicine in the world can do thee good. +In thee, there is not halfe an houre of life; +The Treacherous Instrument is in thy hand, +Vnbated and envenom'd: the foule practise +Hath turn'd it selfe on me. Loe, heere I lye, +Neuer to rise againe: Thy Mothers poyson'd: +I can no more, the King, the King's too blame + + Ham. The point envenom'd too, +Then venome to thy worke. + +Hurts the King. + + All. Treason, Treason + + King. O yet defend me Friends, I am but hurt + + Ham. Heere thou incestuous, murdrous, +Damned Dane, +Drinke off this Potion: Is thy Vnion heere? +Follow my Mother. + +King Dyes. + + Laer. He is iustly seru'd. +It is a poyson temp'red by himselfe: +Exchange forgiuenesse with me, Noble Hamlet; +Mine and my Fathers death come not vpon thee, +Nor thine on me. + +Dyes. + + Ham. Heauen make thee free of it, I follow thee. +I am dead Horatio, wretched Queene adiew, +You that looke pale, and tremble at this chance, +That are but Mutes or audience to this acte: +Had I but time (as this fell Sergeant death +Is strick'd in his Arrest) oh I could tell you. +But let it be: Horatio, I am dead, +Thou liu'st, report me and my causes right +To the vnsatisfied + + Hor. Neuer beleeue it. +I am more an Antike Roman then a Dane: +Heere's yet some Liquor left + + Ham. As th'art a man, giue me the Cup. +Let go, by Heauen Ile haue't. +Oh good Horatio, what a wounded name, +(Things standing thus vnknowne) shall liue behind me. +If thou did'st euer hold me in thy heart, +Absent thee from felicitie awhile, +And in this harsh world draw thy breath in paine, +To tell my Storie. + +March afarre off, and shout within. + +What warlike noyse is this? +Enter Osricke. + + Osr. Yong Fortinbras, with conquest come fro[m] Poland +To th' Ambassadors of England giues this warlike volly + + Ham. O I dye Horatio: +The potent poyson quite ore-crowes my spirit, +I cannot liue to heare the Newes from England, +But I do prophesie th' election lights +On Fortinbras, he ha's my dying voyce, +So tell him with the occurrents more and lesse, +Which haue solicited. The rest is silence. O, o, o, o. + +Dyes + + Hora. Now cracke a Noble heart: +Goodnight sweet Prince, +And flights of Angels sing thee to thy rest, +Why do's the Drumme come hither? +Enter Fortinbras and English Ambassador, with Drumme, Colours, +and +Attendants. + + Fortin. Where is this sight? + Hor. What is it ye would see; +If ought of woe, or wonder, cease your search + + For. His quarry cries on hauocke. Oh proud death, +What feast is toward in thine eternall Cell. +That thou so many Princes, at a shoote, +So bloodily hast strooke + + Amb. The sight is dismall, +And our affaires from England come too late, +The eares are senselesse that should giue vs hearing, +To tell him his command'ment is fulfill'd, +That Rosincrance and Guildensterne are dead: +Where should we haue our thankes? + Hor. Not from his mouth, +Had it th' abilitie of life to thanke you: +He neuer gaue command'ment for their death. +But since so iumpe vpon this bloodie question, +You from the Polake warres, and you from England +Are heere arriued. Giue order that these bodies +High on a stage be placed to the view, +And let me speake to th' yet vnknowing world, +How these things came about. So shall you heare +Of carnall, bloudie, and vnnaturall acts, +Of accidentall iudgements, casuall slaughters +Of death's put on by cunning, and forc'd cause, +And in this vpshot, purposes mistooke, +Falne on the Inuentors head. All this can I +Truly deliuer + + For. Let vs hast to heare it, +And call the Noblest to the Audience. +For me, with sorrow, I embrace my Fortune, +I haue some Rites of memory in this Kingdome, +Which are to claime, my vantage doth +Inuite me, + Hor. Of that I shall haue alwayes cause to speake, +And from his mouth +Whose voyce will draw on more: +But let this same be presently perform'd, +Euen whiles mens mindes are wilde, +Lest more mischance +On plots, and errors happen + + For. Let foure Captaines +Beare Hamlet like a Soldier to the Stage, +For he was likely, had he beene put on +To haue prou'd most royally: +And for his passage, +The Souldiours Musicke, and the rites of Warre +Speake lowdly for him. +Take vp the body; Such a sight as this +Becomes the Field, but heere shewes much amis. +Go, bid the Souldiers shoote. + +Exeunt. Marching: after the which, a Peale of Ordenance are shot +off. + + +FINIS.
