(Σανδώκης), a Persian, son of Thamasius, was one of the royal judges under Dareius Hystaspis, and, having given an unjust sentence under the influence of a bribe, was condemned by the king to crucifixion. But after he had been placed on the cross, Dareius called to mind that his services outweighed his offences, and he was accordingly taken down and pardoned. In B. C. 480, he was viceroy of Cume in Aeolis, and, in the invasion of Greece by Xerxes in that year. commanded a squadron of 15 ships, which were detained behind when the main body left Sepias, and, sailing on afterwards to the south by themselves, were captured by the Greeks off Artemisium.
