Prometheus

In Greek mythology, Prometheus is a Titan, culture hero, and trickster figure who is credited with the creation of man from clay, and who defies the gods and gives fire to humanity (theft of fire), an act that enabled progress and civilization. He is known for his intelligence and as a champion of mankind. 

The punishment of Prometheus as a consequence of the theft is a major theme of his mythology, and is a popular subject of both ancient and modern art. Zeus, king of the Olympian gods, sentenced the Titan to eternal torment for his transgression. The immortal Prometheus was bound to a rock, where each day an eagle, the emblem of Zeus, was sent to feed on his liver, which would then grow back to be eaten again the next day. (In ancient Greece, the liver, rather than the heart, was thought to be the seat of human emotions.) In some stories, Prometheus is freed at last by the hero Heracles (Hercules).
