Who saved Prometheus from his punishment?

The correct answer is Hercules, who is known for his legendary strength and heroic feats in Greek mythology. When Prometheus was punished by Zeus for giving fire to humanity, he was bound to a rock where an eagle would come daily to eat his liver, which would regenerate each night. Hercules, as part of his labors, encountered Prometheus during his quest to obtain the apples of the Hesperides. In an act of compassion, Hercules killed the eagle and freed Prometheus from his torment. This act showcases Hercules' bravery and willingness to confront the wrath of Zeus to aid a fellow being, highlighting themes of heroism and sacrifice.

Perseus, Theseus, and Achilles, though also heroes in Greek mythology, are not connected to the story of Prometheus in this particular context. Perseus is celebrated for slaying Medusa, Theseus is known for defeating the Minotaur, and Achilles is famous for his role in the Trojan War. Their narratives do not involve the rescue of Prometheus, making Hercules the clear choice in this scenario.
