In Hesiod's account of Pandora, which work describes the opening of her jar?

In Hesiod's account of Pandora, Works and Days describes the opening of her jar.

Works and Days is an ancient Greek didactic poem traditionally attributed to Hesiod. It combines advice about farming and justice with myths explaining why human life includes labor and hardship. The Pandora episode appears in that wider discussion of the human condition.

Hesiod also mentions Pandora in Theogony, another major work attributed to him, but the detailed account of the jar, its escaping contents, and the remaining hope is associated with Works and Days. This distinction matters because modern summaries often cite “Hesiod” without naming the specific poem.

The story's placement in Works and Days gives it a moral and social context. It is not an isolated adventure tale; it helps explain why humans must work and why suffering exists. Later writers, artists, and translators expanded the episode into the familiar “Pandora's box” tradition.
