Mithridates (in Greek Mιθριδατης; lived 4th century BC), son of Ariobarzanes prince of Cius, is mentioned by Xenophon¹ as having betrayed his father, and the same circumstance is alluded to by Aristotle². It is possible that he is the same Mithridates who accom­panied the younger Cyrus, but there is no proof of this; also, he may be the same with the Mithridates mentioned by Xenophon³ as satrap of Cappadocia and Lycaonia. It appears that he was dead before 363 BC, when Ariobarzanes II made himself master of the family fiefdom of Cius in Mysia.⁴
