"Prometheus, the clever Titan, created mortal men out of clay and water"
"Now Zeus Who Reigns on High - had only recently become Lord of Olympus and Father of Gods and Men."
"He killed and skinned a huge ox. Then he cut up and separated the rich red meat from the animals white bones ... the clever Titan hid all of the rich ox meat together with the ox's fatty inner parts."
Prometheus was the creator of men. These men that he created were seen as perfect and these creations he took with pride and supplied them with everything that they needed.
Zeus who defeated the Titans and were sent to Hades, became the ruler of all and became the supreme god that held all of the power.
The deceiving mind of Prometheus will eventually get him in trouble with his fate at the end. however, his quick and rash decision was in the best interest of the mortal men that he created. When Zeus see's this he becomes furious, not just because he was tricked but by the fact that his son would have the mind to come up with that.
