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.
This Arion, they say, who for the most part of his time stayed with Periander, conceived a desire to sail to Italy and Sicily; and after he had there acquired large sums of money, he wished to return again to Corinth. He set forth therefore from Taras, and as he had faith in Corinthians more than in other men, he hired a ship with a crew of Corinthians. These, the story says, when out in open sea, formed a plot to cast Arion overboard and so possess his wealth; and he having obtained knowledge of this made entreaties to them, offering them his wealth and asking them to grant him his life. With this however he did not prevail upon them, but the men who were conveying him bade him either slay himself there, that he might receive burial on the land, or leap straightway into the sea. So Arion being driven to a strait entreated them that, since they were so minded, they would allow him to take his stand in full minstrel’s garb upon the deck of the ship and sing; and he promised to put himself to death after he had sung.
They then, well pleased to think that they should hear the best of all minstrels upon earth, drew back from the stern towards the middle of the ship; and he put on the full minstrel’s garb and took his lyre, and standing on the deck performed the Orthian measure. Then as the measure ended, he threw himself into the sea just as he was, in his full minstrel’s garb; and they went on sailing away to Corinth, but him, they say, a dolphin supported on its back and brought him to shore at Tainaron: and when he had come to land he proceeded to Corinth with his minstrel’s garb.
Thither having arrived he related all that had been done; and Periander doubting of his story kept Arion in guard and would let him go nowhere, while he kept careful watch for those who had conveyed him. When these came, he called them and inquired of them if they had any report to make of Arion; and when they said that he was safe in Italy and that they had left him at Taras faring well, Arion suddenly appeared before them in the same guise as when he made his leap from the ship; and they being struck with amazement were no longer able to deny when they were questioned.
