Meaning and history
This name is derived from Greek προμήθεια (prometheia) meaning "foresight, forethought". In Greek myth he was the Titan who gave the knowledge of fire to mankind. For doing this he was punished by Zeus, who had him chained to a rock and caused an eagle to feast daily on his liver, which regenerated itself each night. Heracles eventually freed him. His brother was Epimetheus.
