Guido monologue (Act 5) — The Duchess of Padua

Then let high Paradise Fall into Tartarus! for I shall make This world my heaven for a little space. The sin was mine, if any sin there was. ’Twas I who nurtured murder in my heart, Sweetened my meats, seasoned my wine with it, And in my fancy slew the accursed Duke A hundred times a day. Why, had this man Died half so often as I wished him to, Death had been stalking ever through the house, And murder had not slept. But you, fond heart, Whose little eyes grew tender over a whipt hound, You whom the little children laughed to see Because you brought the sunlight where you passed, You the white angel of God’s purity, This which men call your sin, what was it?
