In Greek mythology, ravens are associated with Apollo, the god of prophecy. They are said to be a symbol of bad luck, and were the god's messengers in the mortal world. According to the mythological narration, Apollo sent a white raven, or crow in some versions to spy on his lover, Coronis. When the raven brought back the news that Coronis has been unfaithful to him, Apollo scorched the raven in his fury, turning the animal's feathers black. That's why all ravens are black today.
