MEANWHILE, the Parthian king, Vologeses, when he heard of Corbulo's achievements and of a foreign prince, Tigranes, having been set over Armenia, though he longed at the same time to avenge the majesty of the Arsacids, which had been insulted by the expulsion of his brother Tiridates, was, on the other hand, drawn to different thoughts as he reflected on the greatness of Rome, and felt reverence for a hitherto unbroken treaty.Naturally irresolute, he was now hampered by a revolt of the Hyrcanians, a powerful tribe, and by several wars arising out of it.Suddenly, as he was wavering, fresh and further tidings of disgrace goaded him to action.Tigranes, quitting Armenia, had ravaged the Adiabeni, a people on its border, too extensively and continuously for mere plundering raids.The chief men of the tribes were indignant at having fallen into such contempt that they were victims to the inroads, not indeed of a Roman general, but of a daring hostage, who for so many years had been numbered among slaves.Their anger was inflamed by Monobazus, who ruled the Adiabeni, and repeatedly asked what protection he was to seek and from what quarter- "Already," he said, "Armenia has been given up, and its borders are being wrested from us, and unless the Parthians help us, we shall find that subjection to Rome is lighter for those who surrender than for the conquered." Tiridates too, exile as he was from his kingdom, by his silence or very moderate complaints made the deeper impression."It is not," he urged, "by weak inaction that great empires are held together; there must be the struggle of brave men in arms; might is right with those who are at the summit of power.And though it is the glory of a private house to keep its own, it is the glory of a king to fight for the possessions of others."Moved by these considerations Vologeses called a council, placed Tiridates by his side, and began to speak as follows: "This man before you, born from the same father as myself, having waived in my favour, on the ground of age, the highest title of all, was established by me in the possession of Armenia, which is accounted the third grade of power.As for Media, Pacorus was already in possession of it.And I thought to myself that I had duly arranged our family and home so as to guard against the old feuds and rivalries of brothers.The Romans thwart me, and though they have never with success to themselves disturbed the peace between us, they are now again breaking it to their own destruction.I will not attempt to deny one thing.It was by just dealing rather than by bloodshed, by having a good cause rather than by arms, that I had wished to retain what my ancestors had won.If I have sinned through irresolution, my valour shall make amends for it.Assuredly your strength and renown are at their height, and you have in addition the repute of obedience, which the greatest of mortals must not despise, and which the gods highly esteem."As he spoke, he encircled Tiridates' brow with a diadem, and to Moneses, a noble, he entrusted a highly efficient body of cavalry, which was the king's customary escort, giving him also some auxiliaries from the Adiabeni, and orders that Tigranes was to be driven out of Armenia.He would himself abandon his feud with the Hyrcanians, and raise his own national force in all its warlike strength by way of menace to the Roman provinces.
When Corbulo had heard all this from messengers he could trust, he sent two legions under Verulanus Severus and Vettius Bolanus to the support of Tigranes, with secret instructions that they were to conduct all their operations with deliberation rather than despatch, as he would prefer to sustain rather than to make war.And indeed he had written to the emperor that a general was wanted specially for the defence of Armenia, and that Syria, threatened as it was by Vologeses, was in yet more imminent peril.Meanwhile he posted his remaining legions on the bank of the Euphrates, armed a hastily collected force of provincials, and occupied with troops the enemy's approaches.
And as the country was deficient in water, he established forts to guard the wells, and concealed some of the streams with heaps of sand.
While Corbulo was thus preparing for the defence of Syria, Moneses rapidly pushed on his forces to anticipate the rumour of his advance, but he did not any the more find Tigranes unaware of or unprepared for his movement.He had, in fact, occupied Tigranocerta, a city strong from the multitude of its defenders and the vastness of its fortifications.In addition, the river Nicephorius, the breadth of which is far from contemptible, circled a portion of its walls, and a wide fosse was drawn where they distrusted the protection of the stream.There were some soldiers too, and supplies previously provided.In the conveyance of these a few men had hurried on too eagerly, and, having been surprised by a sudden attack from the enemy, had inspired their comrades with rage rather than fear.But the Parthian has not the daring in close combat needed for a successful siege.His thin showers of arrows do not alarm men within walls, and only disappoint himself.The Adiabeni, when they began to advance their scaling ladders and engines, were easily driven back, and then cut down by a sally of our men.
