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.
[4] Armand D'Angour notes that Arion's contribution to the reform of the dithyramb, which was eventually performed in a circle and called kuklios choros, was recognised by ancient sources by the fact that they named his father Kukleus ("Circle-man").
On his return trip from Tarentum, whose onomastic founder has a similar story, avaricious sailors plotted to kill Arion and steal the rich prizes he carried home.
Playing his kithara, Arion sang a praise to Apollo, the god of poetry, and his song attracted a number of dolphins around the ship.
[8] At the end of the song, Arion threw himself into the sea rather than be killed, but one of the dolphins saved his life and carried him to safety at the sanctuary of Poseidon at Cape Tainaron.
Melicertes was carried more dead than alive to the shores where the Isthmian Games were celebrated in his honour, as he was transformed to the hero Palaimon, who was placated with a nocturnal chthonic rite, and the whose winners were crowned with a barren wreath of spruce.
[16] A similar story of told of the founding of Taras in Megale Hellas (Magna Graecia), modern Taranto, Apulia, Italy.
When a son of Poseidon called Taras was shipwrecked, his father rescued him by sending a dolphin which he rode to traverse the sea from the promontory of Taenarum to the south of Italy.
[19] C. M. Bowra[20] tied the myth to the period following the expulsion from Corinth of the aristocratic Bacchiadae, who traced their descent from Dionysus: "the cult of the god had to develop new and more democratic forms.
[24] A more literal prose rendering follows: Chiefest of Gods, sea-lord Poseidon of the trident of gold, earth-shaking king of the swelling[a] brine, the beasts that swim dance all about thee with fins, and lightly bound with nimble flingings of the foot, the snub-nosed coarsing hounds of bristling mane, the dolphin-lovers of the Muse, sea-creatures of Nereus' goddess-daughters that he had of Amphitrite, the beasts that bore a wanderer on the Sicilian sea to Taenarum's shore in Pelops' land, ploughing to the untrodden furrow of Nereus' field astride their humpèd back, when crafty men had cast me from out the hollow wave-going ship into the sea-purple billows of the ocean.
In Amor Towles' 2016 novel A Gentleman in Moscow, the Count tells Anna the story of Arion, after tracing freckles that reminded him of a dolphin on her back.
