Prometheus

When the Titans opposed the Olympian gods, Prometheus sided with the gods.

One day, Zeus decided that humans should give sacrifices to the gods because they allow them to live. The next day, Prometheus killed a bull and wrapped the meat in its hide and laid fat-covered bones beside it. Then he called Zeus to choose the pile he wanted the people to sacrifice to the gods. Zeus expected betrayal, but in the end he was deceived anyway. From then on, people sacrificed only bones and fat to the gods.

Out of anger, Zeus smothered all the fire for the people, telling them that if they had meat instead of gods, they should eat it raw. Prometheus felt sorry that the people had lost their fire, so he decided to give it back to them. He stole the fire from the gods and brought it to the people hidden in the hollow of a stick.

For this deed, Prometheus was nailed to a rock. Prometheus, however, did not regret his action even then. So Zeus sent the eagle Ethon, who tore out Prometheus' liver every day. The liver grew back by the next day, and the eagle had enough to eat for 12 generations.

He was finally freed by the hero Heracles, who shot Ethon, freeing Prometheus. He then returned to Olympus. But he still had to carry the rock to which he was attached, at least as a stone in a ring.
