Greek
Pandora
The first woman in Greek myth, and the story of the jar she opened. She is a mortal, not a goddess.
Pandora is not a god. In the poet Hesiod's telling she is the first woman, shaped from clay by Hephaestus and given gifts by the gods, then sent as a bride to Epimetheus. She is mortal. She lifts the lid of a large jar and lets troubles out into the world, but hope stays inside.
The "box" of the popular phrase comes from a later mistranslation of the Greek word for a jar. Her name is often explained as meaning "all gifts", though scholars discuss this.
