The Aquarius should be mapped to the pretty boy, Ganymede.

The beauty of Ganymede was famous in the gods of Greek. One time, the maid in the banquet was absent due to some reason. The almighty Zeus replaced the maid with the boy. From that time, he stayed by the side of Zeus and became one of the constellations in the sky. For the wine that he poured to the cups of those gods was the drink of wisdom, therefore he represented the wisdom of prediction (inference) and invention (science) of the gods. To human beings, he represented the soft circulated mechanism and the system of human body.
