Greek mythology describes various great floods throughout ancient history. Differing sources refer to the flood of Ogyges, the flood of Deucalion, and the flood of Dardanus, though often with similar or even contradictory details. Like most flood myths, these stories often involve themes of divine retribution, the savior of a culture hero, and the birth of a nation or nations. In addition to these floods, Greek mythology also says the world was periodically destroyed by fire, such as in the myth of Phaëton.
