MYTHOLOGY

The best-known myth identifies Aquarius with Ganymede , a beautiful youth with whom Zeus fell in love, and whom he (in the disguise of an eagle, represented as the constellation Aquila ) carried off to Olympus to be cup bearer to the gods. Crater is sometimes identified as his cup.

Aquarius generally resembles the figure of a man, and when considering fainter humanly visible stars, it takes on the image of a man with a bucket from which is pouring a stream. Aquarius was also identified as the pourer of the waters which flooded the earth in the Great Flood , in the Ancient Greek Version of the myth. As such, the constellation Eridanus was sometimes identified as being a river poured out by Aquarius.

It may also, together with the constellation Pegasus , be part of the origin of the myth of the Mares Of Diomedes , which forms one of The Twelve Labours of Heracles . Its association with pouring out rivers, and the nearby constellation of Capricornus , may be the source of the myth of the Augean Stable , which forms another of the labours.
