He chained him to a rock on the top of a high mountain.
He sent a great bird each day to torment him.
Zeus said that he must stay there until he repented and returned the fire to heaven.
There Prometheus stayed and suffered for many burning summers and long, cold winters.
Sometimes he grew faint-hearted and wished to be free.
Then he looked down and saw how the fire was helping the people and how happy they were, and he grew strong again.
After many, many years, a Greek hero who was sailing over the mountain in a golden cup, saw Prometheus.
It was Hercules. He shot the bird with a golden arrow, unbound the chains and set the wise Prometheus free.
