As Mithridates was now at leisure he subdued the
tribes of the Bosporus and appointed Machares, one of his sons, king over them. Then he fell upon the Achæans beyond Colchis (who are supposed to be descended from those who lost their way when returning from the Trojan war), but lost two divisions of his army, partly by open war, partly by the severity of the climate, and partly by stratagem. When he returned home he sent ambassadors to Rome to sign the agreements. At the same time Ariobarzanes, either of his own notion or at the prompting of others, sent thither to complain that Cappadocia had not been delivered up to him, but that a greater part of it was yet retained by Mithridates. Sulla commanded Mithridates to give up Cappadocia. He did so, and then sent another embassy to sign the agreements. But now Sulla had just
died, and as the Senate was otherwise occupied the prætors
did not admit them. So Mithridates persuaded his son-in-law, Tigranes, to make an incursion into Cappadocia as though it were on his own account. This artifice did not deceive the Romans. The Armenian king threw, as it were, a drag net around Cappadocia and made a haul of about 300,000 people, whom he carried off to his own country and settled them, with others, in a certain place where he had first assumed the diadem of Armenia and which he had called after himself, Tigranocerta, or the city of Tigranes.
