Pietro Aretino
Around 1524, Marcantonio was briefly imprisoned by Pope Clement VII for making the I modi set of erotic engravings, from the designs of Giulio Romano, which were later accompanied by sonnets written by Pietro Aretino. At the intercession of the Cardinal Ippolito de' Medici, Baccio Bandinelli and Pietro Aretino, he was released, and set to work on his plate of the "Martyrdom of St. Lawrence" after Bandinelli.
