In the later tradition linking Pandora to the flood survivors, her daughter was Pyrrha.
Pyrrha is usually described as the daughter of Pandora and Epimetheus. She becomes important in the Greek flood story because she and her husband Deucalion survive Zeus’s flood and repopulate the human world after the catastrophe.
The connection joins two mythic cycles: Pandora’s creation and the flood of Deucalion. In that tradition, Pyrrha is not merely a minor descendant; she is one of the two survivors whose actions restore humanity. Some ancient authors and later summaries vary in the precise family details, so genealogies should be tied to the source being discussed.
Pyrrha is also a name found elsewhere in Greek mythology, which can cause confusion. The relevant Pyrrha here is Pandora’s daughter and Deucalion’s wife, not every mythological character who bears the same name.
