(Ἀρίστων), son of Pyrrhichus, a Corinthian, one of those apparently who made their way into Syracuse in the second year of the Sicilian expedition, 414 B. C., is named once by Thucydides, in his account of the sea-fight preceding the arrival of the second armament (413 B. C.), and styled the most skilful steersman on the side of the Syracusans. He suggested to them the stratagem of retiring early, giving the men their meal on the shore, and then renewing the combat unexpectedly, which in that battle gave them their first naval victory. (7.39; comp. Polyaen. 5.13.) Plutarch (Nicias, 20, 25) and Diodorus (13.10) ascribe to him further the invention or introduction at Syracuse of the important alterations in the build of their galleys' bows, mentioned by Thucydides (7.34), and said by him to have been previously used by the Corinthians in the action off Erineus. Plutarch adds, that he fell when the victory was just won, in the last and decisive sea-fight.
