Ganymede is the young, beautyful boy and son of Tros, the King of Troy, and Kallirrhoe.

Zeus fell in love with Ganymede when he spotted him herding his flock on Mount Ida. Zeus then came down in the form of an eagle to carry Ganymede to Mount Olympus where Ganymede became cupbearer to the gods. Zeus gave the grieving Tros two storm footed horses.
