One day, Zeus distributed gifts to all the gods, but he didn't care much for humans. The Titan Prometheus, however, because he loved and felt sorry for humans, climbed up on Olympus and stole the fire from Hephaestus' workshop, put it in a hollow reed and gifted it to the humans. This way, humans could create fire, warm up and make tools. Zeus became very angry when he heard about this. He took Prometheus to a high mountain, the Caucasus, and chained him on a rock with thick chains made by the smith god, Hephaestus. And every day, Zeus would send an eagle that ate Prometheus' liver. For thirty years Prometheus remained bound in the Caucasus, until the great hero Hercules, Zeus' demigod son, released him finally from his torment.
