I Modi (The Ways), also known as The Sixteen Pleasures or under the Latin title De omnibus Veneris Schematibus, is a famous erotic book of the Italian Renaissance in which a series of sexual positions were explicitly depicted in engravings. There are now no known copies of the first two original editions of "I modi" by Marcantonio Raimondi. There is one engraving and nine fragments cut from engravings in the British Museum, and it is thought that these engravings were made by Agostino Veneziano by copying from drawings offset from an original edition of "I modi". There is a booklet of images of sexual scenes created around 1555 that is thought to have been copied from Agostino Veneziano's copy of the "I modi". This booklet of images is thought to copy 12 images from the Agostino veneziano copy of I modi.

One idea for a possible source of inspiration for Giulio Romano when creating the images that became designs for "I modi" were ancient Roman spintria tokens. Marcantonio had worked extensively with Romano's master Raphael, who had died in 1520, producing prints to his designs. The engravings were published by Marcantonio in 1524, and led to his imprisonment by Pope Clement VII and the destruction of all copies of the illustrations. Romano did not become aware of the engravings until the poet Pietro Aretino came to see the original paintings while Romano was still working on them. Romano was not prosecuted since—unlike Marcantonio—his images were not intended for public consumption, and he was not in the Papal States. Aretino then composed sixteen explicit sonnets to accompany the paintings/engravings, and secured Marcantonio's release from prison. I Modi was then published a second time in 1527, now with the sonnets that have given them the traditional English title Aretino's Postures, making this the first time erotic text and images were combined, though the papacy once more seized all the copies it could find. Raimondi escaped prison on this occasion, but the suppression on both occasions was comprehensive. There are presently no remaining copies of the original first edition or the second edition of the "I
