VOLOGESES II., succeeded his father Chosroes, and reigned probably from about A. D. 122 to 149. In A. D. 133, Media, which was then subject to the Parthians, was overrun by a vast horde of Alani (called by Dio Cassius, Albani), who penetrated also into Armenia and Cappadocia, but were induced to retire, partly by the presents of Vologeses, and partly through fear of Arrian, the Roman governor of Cappadocia. (D. C. 69.15.) During the reign of Hadrian, Vologeses continued at peace with the Romans ; and on the accession of Antoninus Pius, A. D. 138, he sent an embassy to Rome, to present the new emperor with a golden crown, which event is commemorated on a coin of Antoninus. (Eckhel, vii. pp. 5, 10, 11.) These friendly relations, however, did not continue undisturbed. Vologeses solicited from Antoninus the restoration of the royal throne of Parthia, which had been taken by Trajan, but did not obtain his request. He made preparations to invade Armenia, but was deterred from doing so by time representations of Antoninus. (Capitol. Anton. Pins, 100.9.)
