Ganymede

In Ancient Greek mythology, Ganymede was the son of King Tros of Troy and the Naiad Callirrhoe. According to Homer's Iliad, he was abducted by Zeus, in the form of an eagle, to serve as cup-bearer in Olympus. Homer describes Ganymede as the most beautiful of mortals. The myth was a model for the Greek social custom of paiderastía, the erotic relationship between an adult male and an adolescent male, although the original version did not include any overtly homosexual elements.

Ganymede was still in the back of Zeus' mind when he went to see his son Perseus get married to the heroine Andromeda. When Zeus got sufficiently into his cups at the wedding feast, he mistook every young waiter for Ganymede.

Christopher Marlowe referenced the story of Ganymede and Jupiter to make the point that his inclination of "boy loving" had not always been regarded as a criminal abomination.
