The armies of the two chiefs were drawn up on the opposite banks of the river, facing one another; and the chiefs themselves, accompanied by an equal number of attendants, proceeded to deliberate in the sight of both hosts.
Satisfactory pledges having been given by the Parthian monarch, the prince and king in turn entertained each other on the borders of their respective dominions; and Caius returned into Syria, having obtained an engagement from the Parthians to abstain from any further interference with Armenian affairs.

The engagement appears to have been honorably kept; for when, shortly afterward, fresh complications occurred, and Caius in endeavoring to settle them received his death-wound before the walls of an Armenian tower, we do not hear of Parthia as in any way involved in the unfortunate occurrence.

The Romans and their partisans in the country were left to settle the Armenian succession as they pleased; and Parthia kept herself wholly aloof from the matters transacted upon her borders.
One cause--perhaps the main cause of this abstinence, and of the engagement to abstain entered into by Phraataces, was doubtless the unsettled state of things in Parthia itself.

The circumstances under which that prince had made himself king, though not unparalleled in the Parthian annals, were such as naturally tended towards civil strife, and as were apt to produce in Parthia internal difficulties, if not disorders or commotions.

Phraataces soon found that he would have a hard task to establish his rule.
