Ganymede of Troy was the cup-bearer of the gods and the lover of Zeus
Ganymede was a very handsome prince of Troy. Zeus, the King of the Gods, fell in love with Ganymede and transformed himself into an eagle. Zeus managed to abduct Ganymede and carried the young man up to his home, Mount Olympus.
Up in Mount Olympus, Ganymede became the lover of Zeus and also served as a cup bearer for the gods, chasing away the olympian servant and daughter of Hera, Hebe.
Zeus wife Hera was very jealous of Zeus' affair with Ganymede, but since she couldn't do any harm to Zeus himself, Hera took revenge by abandoning the Trojans during the Trojan War.
