Thoas and his brother
Phocus, the eponymous founder of
Phocis, were the sons of King
Ornytion, who was the son of
Sisyphus.[2] According to Corinthian tradition, Thoas and his descendants continued to rule Corinth until the coming of the
Heraclids.
Mythology
According to the geographer
Pausanias, Thoas remained in
Corinth, succeeding his father as its ruler, while his brother Phocus led a colony to
Tithorea. Thoas was the father of Damophon, Damophon of Propodas, and Propodas of Doridas and Hyanthidas. During the reign of the latter two, Corinth was seized by the
Dorians under the command of
Aletes, son of Hippotes. The brothers handed control of Corinth to him and were allowed to remain in the city, while the rest of the people were expelled.[3]
