A Dictionary of Greek and Roman biography and mythology

(Ἑρμότιμος), of Pedasa in Caria, fell, when a boy, into the hands of Panionius, a Chian, who made him a cunuch, and sold him to the Persians at Sardis. He was sent thence to Susa as a present to the king, and rose high in favour with Xerxes, whose sons he was commissioned to cunduct back to Asia after the battle of Salamis. Some time before this, when Xerxes was at Sardis, and preparing to invade Greece, Hermotimus went to Atarneus in Mysia, where Panionius was; and having decoyed both him and his sons into his power, took cruel vengeance on then for the injury he had received. (Hdt. 8.104_106.)
