Xenias of Arcadian Parrhasia was a commander of mercenaries in the service of Cyrus the younger, whom he accompanied, with a body of 300 men, to court, when he was summoned thither by his father, Darius Nothus, in 405 BC. After the return of Cyrus to western Asia, we find Xenias commanding for him the garrisons in the several Ionian states, and with the greater portion of these troops, 4000 hoplites, he joined the prince in his expedition against Artaxerxes II, leaving behind only a sufficient number of men to guard the citadels. At Tarsus a large body of his soldiers and of those of Pasion of Megara quit their standards for that of Clearchus of Sparta. Cyrus having afterwards allowed the latter to retain them, Xenias and Pasion abandoned the army at Myriandrus, and sailed away to Greece.
