Pyrrha is the daughter of Pandora and Epimetheus in later Greek flood traditions.
Pyrrha is best known as the wife of Deucalion, the Greek survivor of a catastrophic flood. In the myth, Zeus destroys much of humanity, while Deucalion and Pyrrha survive and later repopulate the world by throwing stones behind them. Their story is often compared with other flood traditions, but it has its own Greek characters and symbolism.
The family connection to Pandora belongs to later mythographic traditions and is not presented in exactly the same way in every ancient source. Some genealogies make Pandora and Epimetheus the parents of Pyrrha, linking the Pandora story to the flood narrative through successive generations.
Pyrrha is not the same person as Pandora. Pandora belongs to the origin story of human suffering, while Pyrrha belongs primarily to the flood and repopulation story. The similar mythic setting can make the names easy to mix up, especially in brief retellings.
