Prometheus tricks Zeus by giving him the bad parts of the ox and when Zeus figures that out he gets furious and takes an important part of the mortal's survival....fire. Zeus is the supreme god
"From this time forth, the ash tree will no longer have the power to house fire's flames!"
"It is Zeus who is Greatest of the Immortals! It is Zeus who is Lord of Gods and Men! Therefore, you and your frail creatures will respect Zeus's power! And you and your frail creatures will fear Zeus's wrath!"
Stealing Fire Back
Fire symbolizes wisdom, knowledge, and survival
"As soon as the blazing sun stretched forth its ravenous tongue and tasted the fennel's pith, Prometheus's heart flooded with joy...once again gave untiring fire to his beloved creates."
Zeus was furious that Prometheus went against him again and this time punished the mortals and Prometheus. Prometheus was sent to a mountain to spend eternity suffering in heat and pain and Zeus sent Pandora to make man suffer. (Fighting between gods)
"Know your place Prometheus! It is Zeus who is the Greatest of the Immortals...Therefore you and your frail creatures will respect Zeus's power! And you and your frail creatures will fear Zeus's wrath.
