Welcome to the Aquarius Page!
The Constellations of Aquarius is one of the 12 zodiac constellations. The constellation’s name means “the water-bearer” (or “cup-bearer”) in Latin.Aquarius lies in the region of the sky which is sometimes referred to as the Sea, because it contains a number of other constellations with names associated with water; Pisces (the fish), Eridanus (the river), and Cetus (the whale), among others.

MYTHOLOGY
Aquarius is depicted as a young man pouring water (or alternatively, nectar) from an amphora into the mouth of the Southern Fish, represented by the constellation Piscis Austrinus.
Aquarius is usually associated with Ganymede, the son of King Tros, in Greek mythology. Ganymede was a beautiful Trojan youth who caught Zeus’ eye, which prompted the god to disguise himself as an eagle (represented by the constellation Aquila) and carry him off to Olympus to serve as cup-bearer to the gods. In a different story, the constellation represents Deucalion, son of Prometheus, who survived the great flood along with his wife Pyrrha. In Babylonian mythology, Aquarius is identified as GU.LA (the great one), the god Ea himself and, in Egyptian tales, the constellation was said to represent the god of the Nile.
