It was to have been expected that Rome would have punished severely the guilt of Pharasmanes in exposing the Empire and its allies to horrors such as always accompany the inroads of a barbarous people. But though the Iberian monarch was compelled to travel to Rome and make his appearance before the Emperor’s tribunal, yet Hadrian, so far from punishing him, was induced to load him with benefits and honors. He permitted him to sacrifice in the Capitol, placed his equestrian statue in the temple of Bellona, and granted him an augmentation of territory. Volagases can scarcely have been pleased at these results of his complaints; he bore them, however, without murmuring, and, when (in A.D. 138) Hadrian died and was succeeded by his adopted son, T. Aurelius, better known as Antoninus Pius, Volagases sent to Rome an embassy of congratulation, and presented the new monarch with a crown of gold.
It was probably at this same time that he ventured to make an unpleasant demand. Hadrian had promised that the golden throne which Trajan had captured, in his expedition, and by which the Parthians set so much store, should be surrendered to them; but this promise he had failed to perform. Volagases appears to have thought that his successor might be more facile, and accordingly instructed his envoys to re-open the subject, to remind Antoninus of the pledged faith of his adopted father, and to make a formal request for the delivery of the valued relic. Antoninus, however, proved as obdurate as Hadrian. He was not to be persuaded by any argument to give back the trophy; and the envoys had to return with the report that their representations upon the point had been in vain, and had wholly failed to move the new Emperor.
