Corvus (constellation)
Corvus is similar to the Babylonian raven (MUL.UGA.MUSHEN). The Babylonians also put the raven sitting on the tail of a snake. The Babylonian constellation was special to the god Adad. Adad was the god of rain and storms. In the time of the Babylonians, the constellation would have risen just before the start of the autum rainy season.
