Jupiter (Zeus) is the most powerful of Greek gods, so he is more powerful than Prometheus. Prometheus had the power of forethought and Zeus had a vast number of powers. Even though they both were powerful, Zeus supremacy can be proved by the fact that he had the ability to punish Prometheus to an eternal torture when the latter gave the human race the gift of fire and the skill of metalwork. According to this punishment, an eagle ate every day the liver of Prometheus who was chained to a rock.
