1. Brother of Darius I., and, according to Herodotus, the trusted

adviser of his nephew Xerxes. Herodotus makes him a principal figure in epic dialogues: he warns Darius not to attack the Scythians (iv. 83; cf. also iv. 143), and predicts to Xerxes his defeat by the Greeks (vii. 10 ff., 46 ff.); Xerxes sent him home to govern the empire during the campaign (vii. 52, 53).
