Which Greek poem links Pandora's creation to the beginning of human suffering?

Works and Days links Pandora's creation to the beginning of human suffering.

Hesiod's Works and Days explains Pandora's arrival as part of Zeus's punishment after Prometheus gave fire to humans. Once Pandora opens the jar, evils spread into the human world, while hope remains inside. The story functions as an etiological myth: it explains why hardship is part of human existence.

The poem is not an adventure epic. It is a practical and moral work addressing farming, seasonal labor, justice, family conduct, and the dangers of idleness and conflict. Pandora's story appears within that argument about the difficult human condition.

The Theogony also mentions Pandora, but Works and Days provides the developed narrative most readers recognize. The poem's title is sometimes translated as Works and Days or Work and Days; the former is the common English article title and answer.
