The exact nature of these terms is not recorded; but they contained at least one unusual condition.

The Romans and Persians agreed that neither party should construct any new fortified post in the vicinity of the other's territory--a loose phrase which was likely to be variously interpreted, and might easily lead to serious complications.
It is difficult to understand this sudden conclusion of peace by a young prince, evidently anxious to reap laurels, who in the first year of his reign had, at the head of a large army, invaded the dominions of a neighbor.

The Roman account, that he invaded, that he was practically unopposed, and that then, out of politeness towards the prefect of the East, he voluntarily retired within his own frontier, "having done nothing disagreeable," is as improbable a narrative as we often meet with, even in the pages of the Byzantine historians.

Something has evidently been kept back.

If Isdigerd returned, as Procopius declares, without effecting anything, he must have been recalled by the occurrence of troubles in some other part of his empire.
