Isthmus of Corinth
In a Corinthian myth related in the 2nd century CE to Pausanias, Briareus, one of the Hecatonchires, was the arbitrator in a dispute between Poseidon and Helios, between the sea and the sun: His verdict was that the Isthmus of Corinth belonged to Poseidon and the acropolis of Corinth (Acrocorinth) to Helios.
