At any rate a king of Pontus, the Mithridates surnamed Euergetes (the Benefactor), who was the first of them inscribed as a friend of the Roman people, and who even sent some ships and a small force of auxiliaries to aid them against the Carthaginians, invaded Cappadocia as though it were a foreign country. He was succeeded by his son, Mithridates, surnamed Dionysus, and also Eupator. The
Romans ordered him to restore Cappadocia to Ariobarzanes,
who had fled to them and who seemed to have a better title to the government of that country than Mithridates; or perhaps they distrusted the growing power of that great monarchy and thought it would be better to have it divided into several parts. Mithridates obeyed the order, but he put an army at the service of Socrates, surnamed Chrestus, the brother of Nicomedes, king of Bithynia, who overthrew the latter and usurped the government. This Nicomedes
was the son of Nicomedes the son of Prusias, who had received
the kingdom of Bithynia as his patrimony at the hands of the Romans. Simultaneously Mithraas and Bagoas drove out Ariobarzanes, whom the Romans had confirmed as king of Cappadocia, and installed Ariarthes in his place.
