Ancient greek flood stories (prehistoric floods of the planet)

Greek mythology describes three floods, the flood of Ogyges, the flood of Deucalion, and the flood of Dardanus. Two of the Greek Ages of Man concluded with a flood: The Ogygian Deluge ended the Silver Age, and the flood of Deucalion ended the First Bronze Age. In addition to these floods, Greek mythology says the world was also periodically destroyed by fire. See Phaëton.
"Many great deluges have taken place during the nine thousand years, for that is the number of years which have elapsed since the time of which I am speaking; and during all of this time and through so many changes, there has never been any considerable accumulation of the soil coming down from the mountains, as in other places, but the earth has fallen away all round and sunk out of sight. The consequence is, that in comparison of what then was, there are remaining only the bones of the wasted body, as they may be called, as in the case of small islands, all the richer and softer parts of the soil having fallen away, and the mere skeleton of the land being left."
Plato’s Critias (111b). The Ogygian flood is so called because it occurred in the time of Ogyges, a mythical king of Attica. The name "Ogyges" and "Ogygian" is synonymous with "primeval", "primal" and "earliest dawn". Others say he was the founder and king of Thebes. In many traditions the Ogygian flood is said to have covered the whole world and was so devastating that Attica remained without kings until the reign of Cecrops. Plato in his Laws, Book III, argues that this flood had occurred ten thousand years before his time, as opposed to only "one or two thousand years that have elapsed" since the discovery of music, and other inventions. Also in Timaeus (22) and in Critias (111-112) he describes the "great deluge of all" as having been preceded by 9,000 years of history before the time of his contemporary Solon, during the 10th millennium BCE. In addition, the texts report that "many great deluges have taken place during the nine thousand years" since Athens and Atlantis were preeminent. The Deucalion legend as told by the Bibliotheca has some similarity to other deluge myths such as the Epic of Gilgamesh and the story of Noah's Ark. The Titan Prometheus advised his son Deucalion to build a chest. All other men perished except for a few who escaped to high mountains. The mountains in Thessaly were parted, and all the world beyond the Isthmus and Peloponnese was overwhelmed. Deucalion and his wife Pyrrha, after floating in the chest for nine days and nights, landed on Parnassus. An older version of the story told by Hellanicus has Deucalion's "ark" landing on Mount Othrys in Thessaly. Another account has him landing on a peak, probably Phouka, in Argolis, later called Nemea. When the rains ceased, he sacrificed to Zeus. Then, at the bidding of Zeus, he threw stones behind him, and they became men, and the stones Pyrrha threw became women. The Bibliotheca gives this as an etymology for Greek Laos "people" as derived from laas "stone". The Megarians told that Megarus, son of Zeus and a Sithnid nymph, escaped Deucalion's flood by swimming to the top of Mount Gerania, guided by the cries of cranes. According to the Theogony of the Bibliotheca, Prometheus moulded men out of water and earth and gave them fire which, unknown to Zeus, he had hidden in a stalk of fennel. When Zeus learned of it, he ordered Hephaestus to nail Prometheus to Mount Caucasus, a Scythian mountain. Prometheus was nailed to the mountain and kept bound for many years. Every day an eagle swooped on him and devoured the lobes of his liver, which grew by night. That was the penalty that Prometheus paid for the theft of fire until Hercules afterwards released him. 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 neighbourhood and Peloponnesus 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. At the bidding of Zeus he took up stones and threw them over his head, and the stones Deucalion threw became men, and the stones Pyrrha threw became women. Hence people were called metaphorically people (Laos) from laas, "a 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 Protogonia, who became the mother of Aethlius by Zeus. Hellen had Dorus, Xuthus, and Aeolus by a nymph Orseis. Those who were called Greeks he named Hellenes after himself, and divided the country among his sons. Xuthus received Peloponnese and begat Achaeus and Ion n by Creusa, daughter of Erechtheus, and from Achaeus and Ion the Achaeans and lonians derive their names. Dorus received the country over against Peloponnese and called the settlers Dorians after himself. Aeolus reigned over the regions about Thessaly and named the inhabitants Aeolians. He married Enarete, daughter of Deimachus, and begat seven sons, Cretheus, Sisyphus, Athamas, Salmoneus, Deion, Magnes, Perieres, and five daughters, Canace, Alcyone, Pisidice, Calyce, Perimede. Perimede had Hippodamas and Orestes by Achelous; and Pisidice had Antiphus and Actor by Myrmidon. Alcyone was married by Ceyx, son of Lucifer. These perished by reason of their pride, for he said that his wife was Hera, and she said that her husband was Zeus. But Zeus turned them into birds; her he made a kingfisher (alcyon) and him a gannet (ceyx). This one has the same basic story line. According to Dionysius of Halicarnassus, Dardanus left Pheneus in Arcadia to colonize a land in the North-East Aegean Sea. When Dardanus' deluge occurred, the land was flooded and the mountain where he and his family survived formed the island of Samothrace. He left Samothrace on an inflated skin to the opposite shores of Asia Minor and settled on Mount Ida. Due to the fear of another flood, they refrained from building a city and lived in the open for fifty years. His grandson Tros eventually moved from the highlands down to a large plain, on a hill that had many rivers flowing down from Ida above. There he built a city, which was named Troy after him. Today, we call the area "the Dardanelles" (formerly known as Hellespont), a narrow strait in northwestern Turkey that connects the Aegean Sea to the Sea of Marmara. The name is derived from Dardania, an ancient land on the Asian shore of the strait which in turn takes its name from Dardanus, the mythical son of Zeus and Electra.
