Hecataeus of Miletus
Hecataeus of Miletus in a fragment from "Genealogiai" states that the "genos" ("clan") descending from Deucalion ruled Thessaly and that it was called "Pelasgia" from king Pelasgus. A second fragment states that Pelasgus was the son of Zeus and Niobe and that his son Lycaon founded a dynasty of kings of Arcadia.
