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 that had engravings of sexual scenes. The engravings were created in a collaboration between Giulio Romano and Marcantonio Raimondi. They were thought to have been created around 1524 to 1527.
There are now no known copies of the first two editions of I modi by Giulio Romano and Marcantonio Raimondi.
In around 1530 Agostino Veneziano is thought to have created a replacement set of engravings for the engravings in I modi by Giulio and Marcantonio.
