Who saved Prometheus from his punishment?

Prometheus, the Titan known for his intelligence and for stealing fire from the gods to give to humanity, was punished by Zeus. His punishment involved being bound to a rock where an eagle would eat his liver daily, only for it to regenerate each night. The hero who saved Prometheus from this cruel punishment was Hercules. This act is part of Hercules' Twelve Labors, showcasing his strength and heroism.

Hercules’ intervention highlights themes of bravery and loyalty, as he sought to free Prometheus despite the dangers involved. The other individuals listed—Perseus, Theseus, and Achilles—are also notable figures in Greek mythology but do not have direct connections to the rescue of Prometheus. Perseus is famous for defeating Medusa, Theseus is known for his adventures including defeating the Minotaur, and Achilles is celebrated for his role in the Trojan War. Thus, Hercules stands out as the correct answer due to his specific action in freeing Prometheus.
