Arion (; ) was a kitharode in ancient Greece, a Dionysiac poet credited with inventing the dithyramb: "As a literary composition for chorus dithyramb was the creation of Arion of Corinth," The islanders of Lesbos claimed him as their native son, but Arion found a patron in Periander, tyrant of Corinth. Although notable for his musical inventions, Arion is chiefly remembered for the fantastic myth of his kidnapping by pirates and miraculous rescue by dolphins, a folktale motif. Herodotus (1,23) says "Arion was second to none of the lyre-players in his time and was also the first man we know of to compose and name the dithyramb and teach it in Corinth". However J.H. Sleeman observes of the dithyramb, or circular chorus, "It is first mentioned by Archilochus (c 665 BC)… Arion flourished at least 50 years later… probably gave it a more artistic form, adding a chorus of 50 people, personating satyrs… who danced around an altar of Dionysus. He was doubtless the first to introduce the dithyramb into Corinth".
