The men who served in the army were the following: the Persians were equipped in this way: they wore on their heads loose caps called tiaras, and on their bodies embroidered sleeved tunics, with scales of iron like the scales of fish in appearance, and trousers on their legs; for shields they had wicker bucklers, with quivers hanging beneath them; they carried short spears, long bows, and reed arrows, and daggers that hung from the girdle by the right thigh. Their commander was Otanes, son of Amestris and father of Xerxes' wife. They were formerly called by the Greeks Cephenes, but by themselves and their neighbors Artaei. When Perseus son of Danae and Zeus had come to Cepheus son of Belus and married his daughter Andromeda, a son was born to him whom he called Perses, and he left him there; for Cepheus had no male offspring; it was from this Perses that the Persians took their name.
