A legend of the Corinthians about their land is not peculiar to them, for I believe that the Athenians were the first to relate a similar story to glorify Attica . The Corinthians say that Poseidon had a dispute with Helius (Sun) about the land, and that Briareos arbitrated between them, assigning to Poseidon the Isthmus and the parts adjoining, and giving to Helius the height above the city.
Ever since, they say, the Isthmus has belonged to Poseidon.
