From Wikipedia, the free encyclopedia
Speculum al foder is an anonymous 15th-century Catalan text discovered in the 1970s.[1][2] This text is significant as it is a rare example of known Medieval treatise describing the art of sexual positions (others examples include Aretino's I Modi ["The Ways"], also known as "The Sixteen Pleasures").[3]
