The more timid counsel had the support of Abdageses, whom Tiridates had made his vizier, and therefore naturally prevailed, the prince himself being moreover of an unwarlike temper. It had, in appearance, much to recommend it; and if its execution had been in the hands of Occidentals might have succeeded. But, in the East, the first movement in retreat is taken as a confession of weakness and almost as an act of despair: an order to “retire” is regarded as a direction to fly. No sooner was the Tigris crossed and the march through Mesopotamia began, than the host of Tiridates melted away like an iceberg in the Gulf Stream. The tribes of the Desert set the example of flight; and in a little time almost the whole army had dispersed, drawing off either to the camp of the enemy or to their homes. Tiridates reached the Euphrates with a mere handful of followers, and crossing into Syria found himself once more safe under the protection of the Romans. The flight of Tiridates gave Parthia back into the hands of its former ruler. Artabanus reoccupied the throne, apparently without having to fight a battle. He seems, however, not to have felt himself strong enough either to resume his designs upon Armenia, or to retaliate in any way upon the Romans for their support of Tiridates. Mithridates, the Iberian, was left in quiet possession of the Armenian kingdom, and Vitellius found himself unmolested on the Euphrates. Tiberius, however, was anxious that the war with Parthia should be formally terminated, and, having failed in his attempts to fill the Parthian throne with a Roman nominee, was ready to acknowledge Artabanus, and eager to enter into a treaty with him. He instructed Vitellius to this effect; and that officer (late in A.D. 36 or early in A.D. 37), having invited Artabanus to an interview on the Euphrates, persuaded him to terms which were regarded by the Romans as highly honorable to themselves, though Artabanus probably did not feel them to be degrading to Parthia. Peace and amity were re-established between the two nations. Rome, it may be assumed, undertook to withhold her countenance from all pretenders to the Parthian throne, and Parthia withdrew her claims upon Armenia. Artabanus was persuaded to send his son, Darius, with some other Parthians of rank, to Rome, and was thus regarded by the Romans as having given hostages for his good behavior. He was also induced to throw a few grains of frankincense on the sacrificial fire which burnt in front of the Roman standards and the Imperial images, an act which was accepted at Rome as one of submission and homage. The terms and circumstances of the peace did not become known in Italy till Tiberius had been succeeded by Caligula (March, A.D. 37). When known, they gave great satisfaction, and were regarded as glorious alike to the negotiator, Vitellius, and to the prince whom he represented. The false report was spread that the Parthian monarch had granted to the new
