son of Ariobarzanes (probably of the first prince of that name), is mentioned by Xenophon (Cyr.
8.8.4) as having betrayed his father, aud the same circumstance is alluded to by Aristotle (Aristot. Pol. 5.10
). Eckhel supposes him to be the same with the Mithridates who accompanied the younger Cyrus, but there is certainly no proof of this.
He may, however, be the same with the Mithridates mentioned by Xenophon (Xen. Anab. 7.8.25
) as satrap of Cappadocia and Lycaonia.
It appears that he was dead before B. C. 363, when Ariobarzanes II. made himself master of the countries which had been subject to his rule. (Diod. 15.90
