Which ancient Greek work contains Hesiod's fuller account of Pandora opening the jar?

Hesiod's fuller account of Pandora opening the jar appears in *Works and Days*.

This poem combines practical advice about farming and household life with reflections on justice, labor, and the condition of humanity. Pandora's story appears as an explanation for why suffering and difficult work exist in the world. The passage follows the story of Prometheus and Zeus's punishment of mortals.

Hesiod also refers to Pandora in the *Theogony*, another major early Greek poem. That reference is shorter and differs in emphasis, so readers seeking the detailed episode usually turn to *Works and Days*. The two works are among the most important surviving sources for early Greek mythology.

Later authors, artists, and translators expanded the story in many directions. The familiar phrase “opening Pandora's box” therefore reflects a long afterlife of the myth, while the earliest detailed literary account remains Hesiod's poem.
