Arion - largely legendary lyric poet of the seventh century, said to have been born on Lesbos, and to have been a pupil of Alcman. He later lived at the court of Periander in Corinth. According to legend, while on the way back from a visit to Italy, he was thrown overboard by pirates, but a dolphin, charmed by Arion’s singing, carried him to land. He is credited with inventing the dithyramb, a form of choral lyric poetry.
