Definition: Arion of Methymna, the legendary man credited with the invention of the dithyramb at Corinth, where Periander was tyrant, rode upon a dolphin's back to Taenarus. Arion had been visiting Sicily and Italy where he may have earned money as a singer, and was returning home on a Corinthian merchant ship setting out from Tarentum (Taras) when, facing death by merchants turned pirates on shipboard, he first sang a song and then jumped into the sea. There a dolphin rescued him, possibly summoned beforehand by the song.
His story is told in Herodotus I.23.
Examples:
Arion is also the name of a horse son of Poseidon.
