The water carrier represented by the zodiacal constellation Aquarius is Ganymede, a beautiful Phrygian youth. Ganymede was the son of Tros, king of Troy (according to Lucian, he was also son of Dardanus). While tending his father's flocks on Mount Ida, Ganymede was spotted by Jupiter. The king of gods became enamored of the boy and flew down to the mountain in the form of a large bird, whisking Ganymede away to the heavens. Ever since, the boy has served as cupbearer to the gods. Ovid has Orpheus sing the tale:

"The king of the gods was once fired with love for Phrygian Ganymede, and when that happened Jupiter found another shape preferable to his own. Wishing to turn himself into a bird, he none the less scorned to change into any save that which can carry his thunderbolts. Then without delay, beating the air on borrowed pinions, he snatched away the shepherd of Ilium, who even now mixes the winecups, and supplies Jove with nectar, to the annoyance of Juno" (Metamorphoses X 154-160).
