In Greece there was 2 brothers named Epimetheus and Prometheus. They always made the Gods angry especially, Zeus.
So then Zeus came up with a plan to punish the two brothers. With the help of Hephaestos, he created a woman from clay. The goddess Athena then breathed life into the clay, Aphrodite made her very beautiful, and Hermes taught her how to be both charming and deceitful. Zeus called her Pandora and sent her as a gift to Epimetheus.
Prometheus did warn his brother about gifts from the Gods, but Epimetheus really loved Pandora. So then they got married and Zeus gave a box to Pandora as a wedding gift but he said never to open it and Pandora promised to never open it.
Pandora was always really curious, so then one day she decided to open it, so she slid the key into the hole turned the key then opened the box, she was expecting to find gold or silver inside but instead she found out that inside the box was all the evil of the world, plagues, and diseases. Then all that was inside was nothing but Hope. Hope came out of the box and touched the wounds that the created by the evil creatures and healing them. Even though Pandora had released evilness to the world, she had also allowed Hope to follow them.
