Ganymede

Ganymede was a son of Tros, who was the ruler of the city of Troy. He lived on the island of Crete. One day, Zeus saw Ganymede as he guarded his sheep, and wanted to make the young man the servant of the gods at Olympus. Zeus changed his shape into that of an eagle, swooped down and carried the boy off to Mount Olympus.

Ganymede became Zeus' favorite companion. He placed the eagle into the heavens as the constellation Aquila (eagle), and then Ganymede as the constellation Aquarius (water bearer). One of Jupiter's moons is also named after Ganymede.
