For his crimes, Prometheus was punished by Zeus, who bound him with chains and sent an eagle to eat Prometheus' immortal liver every day, which then grew back every night. Years later, the Greek hero Heracles, with Zeus' permission, killed the eagle and freed Prometheus from this torment (521–529).
