I think you are talking about Prometheus. Prometheus was Zeus's servant. He gave mankind fire, but Zeus did not want him to. Humans thought fire was magic and when they found out that it wasn't, Zeus feared they would think the gods weren't as majestic and worthy. So, when Prometheus gave humans fire, Zeus found him and tied him to a pole where he would send an eagle to eat his liver every day. But, by the next morning, it would have grown back. Prometheus suffered this because he knew Hercules would rescue him. Prometheus could see into the future, so he knew this. That is why Zeus kept him around. Hercules rescued Prometheus. So, that's the story.
After Prometheus was freed by Herakles, Zeus' son, he forgave him.

Prometheus helped humans (he gave them the fire of the Gods). This made Zeus cross and the then punished Prometheus for doing this in a terrible way.
