The Histories · 1.23

As for Periander, the man who gave information about the oracle to Thrasybulos, he was the son of Kypselos, and despot of Corinth. In his life, say the Corinthians, (and with them agree the Lesbians), there happened to him a very great marvel, namely that Arion of Methymna was carried ashore at Tainaron upon a dolphin's back. This man was a harper second to none of those who then lived, and the first, so far as we know, who composed a dithyramb, naming it so and teaching it to a chorus at Corinth.
