Homosexuality in ancient Greece
In classical antiquity, writers such as Herodotus, Plato, Xenophon, Athenaeus and many others explored aspects of homosexuality in Greek society. This often took the form of pederasty, usually seen among some elite circles, involving an adult man with an adolescent boy (marriages in Ancient Greece between men and women were also age structured, with men in their thirties commonly taking wives in their early teens).
