Phocus of Corinth
In Greek mythology, Phocus the Corinthian, was a son of Ornytion and grandson of Sisyphus; some called him son of Poseidon. Thus he might be the same as the son of Poseidon and Pronoe referenced in the scholia on Iliad, see above. Leaving the kingdom of Corinth to his brother Thoas, he led a colony to the region of Tithorea and Mount Parnassus; the land came to be named Phocis after him.
Phocus is said to have cured the wandering Antiope of her madness, which she had been struck with by Dionysus who was outraged by Dirce's death, and to have married her; they were buried in one and the same grave.
