Pandora
Theogonis seems to be referring to a different version of the myth: In that version, the jar contained blessings rather than evils. This version seems to follow a tradition before Hesiod, which was preserved by 2nd century writer  Babrius. According to Babrius, the gods sent a jar containing blessings to humans. A "foolish man" (not Pandora) opened the jar, and most of the blessings were lost forever. Only hope remained, "to promise each of us the good things that fled."
