In Greek mythology, the woman who opened the container releasing human troubles was Pandora.
Pandora was created by the gods in the myth told most fully by the poet Hesiod. Zeus sent her to Epimetheus, the brother of Prometheus, after Prometheus had given fire to humanity. The gods furnished Pandora with different gifts, helping explain her name, which is commonly interpreted as “all-gifted.”
The familiar expression “Pandora’s box” is slightly inaccurate. Hesiod described a large storage jar, called a pithos in Greek, rather than a hinged box. When Pandora opened it, evils or troubles escaped into the world; hope remained inside or was otherwise associated with the vessel, depending on how the passage is interpreted. The story is therefore not simply a tale about curiosity: it is also an ancient explanation for why suffering exists.
