Gotarzes died of a sickness, not before June, 51 A.D., and was followed by Vonones II, who had been king in Atropatene, and was probably a brother of Artabanus III. According to the coins his short reign began before September, 51 A.D., and did not end before October, 54 A.D. He was succeeded by his eldest son, Volagases I, the brothers acquiescing in his advancement, although his mother was only a concubine from Miletus; and receiving their compensation by being nominated to kingdoms which gave them the second and third places after the king of kings—Pacorus to Media or Atropatene, and Tiridates to Armenia. The Armenians now offered no resistance to the Parthians, but the Romans were not content to lose their influence in the land. Open war with Rome, however, was still delayed by negotiations. Finally Rome refused to confirm a treaty, and war was declared. The first year of the war (62 A.D.) was unfortunate for the Romans. Next year the war was resumed, and Corbulo, crossing the Euphrates at Melitene, had penetrated into Sophene when the Parthians earnestly sought peace. It was agreed that Tiridates should lay down his diadem and go to Rome in person to receive it again from the emperor, which was done accordingly in 66 A.D. The real advantage of the war lay more with Parthia than with Rome; for if the Roman suzerainty over Armenia was admitted, the Parthians had succeeded, after a contest which had lasted a generation, in placing an Arsacid on the Armenian throne. After Nero’s death Volagases (Vologeses) formed very friendly relations with Vespasian, which endured till 75 A.D.
Volagases I died soon after the Alan wars, leaving a just reputation by his friendly relation to his brothers (a relation so long unknown), his patient steadfastness in foreign war and home troubles, and his foundation of a new capital. Perhaps also he has the merit of collecting from fragments or oral tradition all that remained of the Avesta. From June, 78 A.D., we find two kings coining and reigning together, Volagases II and Pacorus II, probably brothers. From 79 A.D. there is a long break in the coins of the former, and Artabanus IV takes his place with a coin struck in July, 81 A.D. This Artabanus appears as the protector of a certain Terentius Maximus, who pretended to be Nero; he threatened to restore him and displace Titus by force, and though the pretender was at length given up, the farce, which was kept up till 88 A.D., might have ended in earnest but for the disorders of the times—indicated by a break in the Parthian coinage between 84 and 93 A.D., in which latter year Pacorus appears as sole king.
[88-116 A.D.]
At this time the political horizon of Parthia was very wide, and its intercourse with the farthest East was livelier than at any other date. In 90 A.D. the Yue-chi had come to war with the governor of Chinese Tatary and been reduced to vassalship: in 94 A.D. a Chinese expedition slew their king, and advancing to the “North Sea” (Lake Aral) subdued fifty kingdoms. The Tochari, one sees, like the Greeks before them, had neglected the lands north of the Hindu-Kush in their designs on India; even of Ooemo-Kadphises no coins are found north of that range. In 97 A.D. Chinese envoys directed to Rome actually reached the Mediterranean, but were dissuaded from going further from Parthian accounts of the terrors of the sea voyage; and in 101 A.D. Muon-kiu, king of An-si (Parthians), sent lions and gazelles to the emperor of China. Muon-kiu reigned in Ho-to—
But at any rate the representative of the Parthian power in the West was still Pacorus II, who in 110 A.D. sold the crown of Edessa to Abgar VII, bar Izat, and died soon after, making way for his brother Osroes, who had to reckon with two rivals—Volagases II from 112 A.D. onwards, and Meherdates (Mithridates) VI. The latter was a brother of Osroes, and so probably was the former. None of the three was strong enough to conquer the others, and continual war went on between them till Osroes was foolish enough to provoke Roman intervention by taking Armenia from Exedares, son of Pacorus, to whose appointment Rome had not objected, and transferring it to another son of Pacorus called Parthamasiris.
