Which ancient Greek work describes Pandora’s jar being opened?

Hesiod’s Works and Days describes Pandora’s jar being opened. The poem presents the episode while explaining how troubles entered human life after the conflict between Zeus and Prometheus.

In the story, Zeus has Pandora brought to Epimetheus. She opens the container, and the destructive contents spread into the world. The narrative is part of a larger discussion of human labor, justice, and the difficult condition of mortal life.

The Theogony also contains a Pandora episode, but it focuses more on her creation and the gods’ contributions. Works and Days is the Hesiodic work most directly associated with the opening of the container and the resulting release of evils.

The poem is not an adventure epic like Homer’s Iliad or Odyssey. It is a didactic work combining myth, practical advice, farming guidance, moral instruction, and reflections on justice.
