Prometheus, forethought, was a Greek heroic god, worshipped from about 800 BC to Christianization, c.a. 400 AD. His cult center was predominantly Athens, and mentioned in Hesiod’s Theogony and Aeschylus drama. This deity was one of four sons of Iapetos and Klymene, both Titans. He is probably known as an heroic opponent of Zeus. Legend tells that Prometheus stole fire from Zeus and gave it to humanity as a boon that separates the human race from all living things. Legend further accords to him and his brother Epimetheus, the creation of humankind and its protector, in response Zeus created Pandora and her box containing the problem when set loose afflicted all human kind. Zeus also imprisoned Prometheus by fastening to a great rock in the Caucasus Mountains with adamantine chains and sending an eagle to eat his liver. He was rescued by Hercules, who killed the eagle, thus liberating the god from his torment. A.G.H.
