Which Greek work by Hesiod describes Pandora’s jar as part of a punishment for humanity?

Works and Days is the Hesiodic poem that describes Pandora’s jar as part of Zeus’s punishment for humanity. The poem combines farming advice, moral instruction and mythic narratives, including the creation of Pandora after Prometheus deceives Zeus and steals fire.

In the poem, Zeus orders the gods to make Pandora and sends her to Epimetheus. When she opens the vessel, destructive forces spread among humans, while hope remains inside. This passage is the earliest surviving full account of the jar episode.

Hesiod’s Theogony mentions Pandora but does not narrate the opening in the same detailed way. The two poems are therefore related but not interchangeable sources. Works and Days is usually dated to the late eighth or early seventh century BCE, though exact dating remains debated.
