Corvus

"Corvus is one of the 48 constellations identified by the astronomer Ptolemy in the second century. Its name means “crow” in Latin. It is an ancient constellation that was known since the time of the Babylonians. They saw it as a raven, and it was sacred to Adad, the god of rain and storm. To the ancient Greeks, it was a crow sent by Apollo to fetch water. The raven wasted his time eating figs. After returning late, Apollo punished him by throwing him into the heavens. He was also condemned to endure eternal thirst. This is why the crow caws instead of singing like other birds."
