The Great Flood: mythological story about a great destruction that once befell the earth. There are several variants; the Biblical version is the most famous. The possibility that there is a historical event behind the story (a local flood in southern Babylonia in the twenty-eighth century BCE) cannot be excluded.
One of the Greek versions can be found in the book called The Library, attributed to Apollodorus of Alexandria, a second-century BCE author. Section 1.7.2 is offered here in a translation by James Frazer.
And Prometheus had a son Deucalion. He reigning in the regions about Phthia, married Pyrrha, the daughter of Epimetheus and Pandora, the first woman fashioned by the gods. And when Zeus would destroy the men of the Bronze Age, Deucalion by the advice of Prometheus constructed a chest, and having stored it with provisions he embarked in it with Pyrrha.
But Zeus by pouring heavy rain from heaven flooded the greater part of Greece, so that all men were destroyed, except a few who fled to the high mountains in the neighborhood. It was then that the mountains in Thessaly parted, and that all the world outside the Isthmus and Peloponnese was overwhelmed.
But Deucalion, floating in the chest over the sea for nine days and as many nights, drifted to Parnassus, and there, when the rain ceased, he landed and sacrificed to Zeus, the god of Escape.
And Zeus sent Hermes to him and allowed him to choose what he would, and he chose to get men. And at the bidding of Zeus he took up stones and threw them over his head, and the stones which Deucalion threw became men, and the stones which Pyrrha threw became women. Hence people were called metaphorically people (laos) from laas, "stone".
And Deucalion had children by Pyrrha, first Hellen, whose father some say was Zeus, and second Amphictyon, who reigned over Attica after Cranaus; and third a daughter Protogenia, who became the mother of Aethlius by Zeus.
