Mythology of Corvus
The constellation CORVUS represents the crow or raven who was given a chalice by Apollo and sent to collect the waters of life. Instead of flying straight to his task, the bird spent many days waiting around for the fruit of a fig tree to ripen before eating it. When he did eventually return to his master, he excused his tardiness by claiming that a watersnake had delayed him. Apollo was so annoyed that he cursed the wretched bird with eternal thirst and threw him into the heavens. The cup, CRATER, was also placed there, carefully guarded by the watersnake, HYDRA.
