Now Messer Giovanni bought his favourite a very fine black horse, for which he paid 150 crowns. The beast was admirably trained to hand, so that Luigi could go daily to caracole around the lodgings of that prostitute Pantasilea. Though I took notice of this, I paid it no attention, only remarking that all things acted as their nature prompted; and meanwhile I gave my whole mind to my studies. It came to pass one Sunday evening that we were invited to sup together with the Sienese sculptor, Michel Agnolo, and the time of the year was summer. Bachiacca, of whom I have already spoken, was present at the party; and he had brought with him his old flame, Pantasilea. When we were at table, she sat between me and Bachiacca; but in the very middle of the banquet she rose, and excused herself upon the pretext of a natural need, saying she would speedily return. We, meanwhile, continued talking very agreeably and supping; but she remained an unaccountably long time absent. It chanced that, keeping my ears open, I thought I heard a sort of subdued tittering in the street below. I had a knife in hand, which I was using for my service at the table. The window was so close to where I sat, that, by merely rising, I could see Luigi in the street, together with Pantasilea; and I heard Luigi saying: “Oh, if that devil Benvenuto only saw us, shouldn't we just catch it!” She answered: “Have no fear; only listen to the noise they're making; we are the last thing they're thinking of.” At these words, having made them both well out, I leaped from the window, and took Luigi by the cape; and certainly I should then have killed him with the knife I held, but that he was riding a white horse, to which he clapped spurs, leaving his cape in my grasp, in order to preserve his life. Pantasilea took to her heels in the direction of a neighbouring church. The company at supper rose immediately, and came down, entreating me in a body to refrain from putting myself and them to inconvenience for a strumpet.
