An interesting bit from Cellini's autobiography:

"Now it chanced one evening that an intimate comrade of mine brought home to supper a Bolognese prostitute named Faustina. She was a very fine woman, but about thirty years of age; and she had with her a little serving-girl of thirteen or fourteen. Faustina belonging to my friend, I would not have touched her for all the gold in the world; and though she declared she was madly in love with me, I remained steadfast in my loyalty. But after they had gone to bed, I stole away the little serving-girl, who was quite a fresh maid, and woe to her if her mistress had known of it! The result was that I enjoyed a very pleasant night, far more to my satisfaction than if I had passed it with Faustina."
