Pandora (păndôr'u) [key], in Greek mythology, first woman on earth. Zeus ordered Hephaestus to create her as vengeance upon man and his benefactor, Prometheus. The gods endowed her with every charm, together with curiosity and deceit. Zeus sent her as a wife to Epimetheus, Prometheus' simple brother, and gave her a box that he forbade her to open. Despite Prometheus' warnings, Epimetheus allowed her to open the box and let out all the evils that have since afflicted man. Hope alone remained inside the box

I found this today, I was thinking along the lines of Pandora's Box too
