After Prometheus' theft of the secret of fire, Zeus ordered Hephaestus to create the first woman, Pandora, as part of the punishment of mankind. Pandora was given many seductive gifts from Aphrodite, Hermes, Hera, Charites, and Horae (according to Works and Days). For fear of additional reprisals, Prometheus warned his brother Epimetheus not to accept any gifts from Zeus, but Epimetheus did not listen, and married Pandora. Pandora had been given a large jar and instruction by Zeus to keep it closed, but she had also been given the gift of curiosity, and ultimately opened it. When she did so, all of the evils, ills, diseases, and burdensome labor that mankind had not known previously, escaped from the jar, but it is said, that at the very bottom of her jar, there lay hope. According to author Willem Verdenius, the myth is not intended to imply that Pandora acted out of malice in opening the jar as she quickly closed the jar immediately after opening it. Rather her curiosity is said to have been the cause of her actions.
