Homosexuality [PDF ebook] 
A History (From Ancient Greece to Gay Liberation)

Originally published in 1979. This is at once a look at the realities of homosexuality in history and an examination of the myths that have grown up around it. The record of practices and prejudices moves from biblical and classical through early and medieval Christian, Renaissance, and Victorian times, to our own era of dramatic changes. It looks at prominent figures who were homosexuals, the theories that have flourished and faded, the differing attitudes toward male and female homosexuality, persecution, and contemporary changes. This classic work is a fascinating historical perspective of all the factors that have shaped and changed our attitudes from ancient times to the present.
