Great Prometheus did not steal just ordinary fire from the heavens - he stole the firesoul, the divine spark of consciousness itself.
By gifting it to men, who then were akin to animals living on instinct, he sought to bring about man's enlightenment.
But consciousness did not just bring thought and creativity. It also brought with it the knowledge and awareness of suffering and death.
And as mankind was not yet ready to learn and receive the concept of dying, man became chained to material existence and material desires - the lower principalities of lust, greed, lack, etc.
Why Prometheus, as just punishment, found himself chained to the Caucasus - with the ever-renewing lifeforce of his liver to be forever pecked at by a great eagle, until the fated day of his liberation.
If only you knew just how much more there is to the story.
Truly, we live in the cradle of titans and gods.
