Pederasty in ancient Greece was a socially acknowledged relationship between an older male (the erastes) and a younger male (the eromenos) usually in his teens.
Some scholars locate its origin in initiation ritual, particularly rites of passage on Crete, where it was associated with entrance into military life and the religion of Zeus. It has no formal existence in the Homeric epics, and may have developed in the late 7th century BC as an aspect of Greek homosocial culture, which was characterized also by athletic and artistic nudity, delayed marriage for aristocrats, symposia, and the social seclusion of women.
