An engraving by the Italian illustrator Agostino Carracci, The Cult of Priapus. Part of a book published in the late 1500s entitled The Sixteen Pleasures depicting explicit sex acts under the thin veneer of “mythological studies”. Here we have two satyrs getting it on as Priapus himself oversees the action with his huge boner.
