The grand ideas with which he had entered upon the contest had consequently to be abandoned; and it had to be recognized that the struggle with Rome was one in which the two parties were very evenly matched, one in which it was not to be supposed that either side would very soon obtain any decided preponderance.

Under these circumstances the grand ideas were quietly dropped; the army which had been gathered together to enforce them was allowed to disperse, and was not required within any given time to reassemble; it is not unlikely that (as Niebuhr conjectures) a peace was made, though whether Rome ceded any of her territory by its terms is exceedingly doubtful.

Probably the general principle of the arrangement was a return to the _status quo ante bellum_, or, in other words, the acceptance by either side, as the true territorial limits between Rome and Persia, of those boundaries which had been previously held to divide the imperial possessions from the dominions of the Arsacidse.
The issue of the struggle was no doubt disappointing to Artaxerxes; but if, on the one hand, it dispelled some illusions and proved to him that the Roman State, though verging to its decline, nevertheless still possessed a vigor and a life which he had been far from anticipating, on the other hand it left him free to concentrate his efforts on the reduction of Armenia, which was really of more importance to him, from Armenia being the great stronghold of the Arsacid power, than the nominal attachment to the empire of half-a-dozen Roman provinces.

So long as Arsacidae maintained themselves in a position of independence and substantial power so near the Persian borders, and in a country of such extent and such vast natural strength as Armenia, there could not but be a danger of reaction, of the nations again reverting to the yoke whereto they had by long use become accustomed, and of the star of the Sasanidae paling before that of the former masters of Asia.

It was essential to the consolidation of the new Persian Empire that Armenia should be subjugated, or at any rate that Arsacidae should cease to govern it; and the fact that the peace which appears to have been made between Rome and Persia, A.D.232, set Artaxerxes at liberty to direct all his endeavors to the establishment of such relations between his own state and Armenia as he deemed required by public policy and necessary for the security of his own power, must be regarded as one of paramount importance, and as probably one of the causes mainly actuating him in the negotiations and inclining him to consent to peace on any fair and equitable terms.
