7. TIRIDATES II., king of Armenia, was the son of the Armenian king Vologeses. He was in the power of the Romans, from whom he escaped, and fled for refuge to Vologeses V. (Arsaces XXX.), king of Parthia. The Parthians, however, surrendered him to Caracalla, when the latter demanded him in A. D. 215, and backed his demand with an army. Tiridates must, however, have again escaped from captivity, for we find him at a later time on the Armenian throne. Macrinus, who was unwilling to prosecute the war against him, which had been commenced by Caracalla, concluded a peace with him, and sent him the diadem. (D. C. 77.19, 21, 78.27, with the notes of Reimarus.)
