Periander, who disclosed the oracle's answer to Thrasybulus, was the son of Cypselus, and sovereign of Corinth . The Corinthians say (and the Lesbians agree) that the most marvellous thing that happened to him in his life was the landing on Taenarus of Arion of Methymna , brought there by a dolphin. This Arion was a lyre-player second to none in that age; he was the first man whom we know to compose and name the dithyramb which he afterwards taught at Corinth .
