Quote Explication:

O serpent heart, hid with a flowring face!Did ever dragon keep so far a cave?Beautiful tyrant, fiend angelical!Dove-feathered raven, wolvish-ravening lamb!Despisd substance of divinest show!Just opposite to what thou justly seemst,A damnd saint, an honourable villain!O nature, what hadst thou to do in hellWhen thou didst bower the spirit of a fiendIn mortal paradise of such sweet flesh?

Let me be tane, let me be put to death,I am content, so thou wilt have it so.Ill say yon grey is not the mornings eye,Tis but the pale reflex of Cynthias brow;Nor that is not the lark whose notes do beatThe vault heaven so high above our heads.I have more care to stay than will to go:Come, death, and welcome! Juliet wills it so.How ist , my sol? Lets talk, it is not day.
