    To perfect his horror, Caesar, surrounded at the base of the statue by the impatient daggers of his friends,
    discovers among the faces and blades that of Marcus Brutus, his protege, perhaps his son, and he no longer
    defends himself, but instead exclaims: 'You too, my son!' Shakespeare and Quevedo capture the pathetic cry.

        y ya no se defiende y exclama: ¡Tú también, hijo mío! Shakespeare y Quevedo recogen el patético grito.
