In Hyginus’s account, Pandora’s daughter was called Pyrrha. Pyrrha is a major figure in the Greek flood myth and is paired with Deucalion, the son of Prometheus.
Hyginus connects Pandora to the generations that survive the destruction of humanity. In the broader mythic tradition, Zeus sends a flood, and Deucalion and Pyrrha survive by taking refuge in a chest or ark-like vessel. Afterward, they repopulate the earth by throwing stones behind them, which become human beings.
This genealogy is easy to confuse with the story of Pandora’s vessel. Pandora’s container brings evils into the world, while Deucalion and Pyrrha’s survival vessel belongs to a later flood episode. The two stories are linked by family relationships and themes of human origins, but they are not the same object or event.
