DEUCALION, in Greek legend, son of Prometheus, king of Phthia in Thessaly, husband of Pyrrha, and father of Hellen, the mythical ancestor of the Hellenic race.
In the diagrammatic family tree of the Greek people, as it appears in the Hesiodic catalogue (6th century) and in Hellanicus (5th century), the " sons of Hellen " are Dorus, Xuthus (father of Ion and Achaeus) and Aeolus.
Dorus' share of the inheritance of Hellen lay in central Greece, north of the Corinthian Gulf, between Xuthus in north Peloponnese and Aeolus in Thessaly.
The almost total absence from Homer not only of "Dorians " but of " Ionians " and even of " Hellenes "leads to the conclusion that the diagrammatic genealogy of the " sons of Hellen " is of post-Homeric date; and that it originated as an attempt to classify the Doric, Ionic and Aeolic groups of Hellenic settlements on the west coast of Asia Minor, for here alone do the three names correspond to territorial, linguistic and political divisions.
Here clearly two traditions are combined: - one, in which the Dorians originated from Hellas in south Thessaly, and so are " children of Hellen "; another, in which they were a " Macedonian people " intruded from the north, from Pindus, past Histiaeotis to Doris and beyond.
