Know, then, that there dwelt aforetime at Arezzo a rich man, Tofano by name, who took to wife Monna Ghita, a lady exceeding fair, of whom, for what cause he knew not, he presently grew jealous. Whereof the lady being ware, waxed resentful, and having on divers occasions demanded of him the reason of his jealousy, and gotten from him nought precise, but only generalities and trivialities, resolved at last to give him cause enough to die of that evil which without cause he so much dreaded. And being ware that a gallant, whom she deemed well worthy of her, was enamoured of her, she, using due discretion, came to an understanding with him; which being brought to the point that it only remained to give effect to their words in act, the lady cast about to devise how this might be. And witting that, among other bad habits that her husband had, he was too fond of his cups, she would not only commend indulgence, but cunningly and not seldom incite him thereto; insomuch that,well-nigh as often as she was so minded, she led him to drink to excess; and when she saw that he was well drunken, she would put him to bed; and so not once only but divers times without any manner of risk she forgathered with her lover; nay, presuming upon her husband's intoxication, she grew so bold that, not content with bringing her lover into her house, she would at times go spend a great part of the night with him at his house, which was not far off.
