Michel Foucault had already written extensively about medicine, madness, and prisons. But in the latter days of his career, he turned to the subject of sexuality, planning six volumes on the subject. He completed three before dying of an AIDS-related illness in 1984. Foucault's History of Sexuality Vol. 1 is a study of the evolution of cultural ideas about sex in the West since the end of the 17th century. Volume two looked at attitudes toward sex in ancient Greece; volume three investigated sex in ancient Rome.
