Prometheus was a Titan that always looked towards the future. He did not want to take part of Jupiter and the Might-Ones activity's on mount Olympus. Instead he went to live with the humans.
Lets make her beautiful and curious!
Jupiter did not believe in helping the humans, so he forced them to live like beasts. Prometheus decided he would teach the beast-like humans to become civil. When walking along the beach he found a reed which he used to catch fire from the sun.
We got Married!
With the reed of fire, Prometheus taught the humans how to cook food, survive with nature and build houses. The humans praised Prometheus' name!
Must be Jewels!
And by chance, Jupiter looks down upon earth and see's what Prometheus is doing. He calls a meeting with the other gods and they hatch a fool-proof plan. Jupiter forms a beautiful young maiden and gives her gifts of curiosity and beauty. Jupiter named his creation Pandora, Athena gifted Pandora a golden box and she warned her to never open it.
And then Jupiter sent Pandora down to earth to meet with Prometheus' younger brother, Epimethius. At seeing her beauty, Epimethius made Pandora his wife. And even Prometheus was pleased by her beauty.
However, Pandora became curious. What was inside of her box, and why was she not allowed to open it? "It must be jewels." She thought. And so, she opened it. Once she opened the lid, evil looking creatures erupted into the air. The creatures were diseases, and they embedded themselves inside all of the humans on Earth. The End.
