CLAUDIO. O Hero! what a Hero hadst thou been, If half thy outward graces had been plac’d About thy thoughts and counsels of thy heart! But fare thee well, most foul, most fair! farewell, Thou pure impiety, and impious purity! For thee I’ll lock up all the gates of love, And on my eyelids shall conjecture hang, To turn all beauty into thoughts of harm, And never shall it more be gracious.
