The failure of Nachoragan, following closely upon the decision of the Lazi to maintain their alliance with Rome in spite of the murder of Gubazes, seems to have convinced the Persian monarch that, in endeavoring to annex Lazica, he had engaged in a hopeless enterprise, and that it would be the most prudent and judicious course to yield to the inevitable, and gradually withdraw from a position which was untenable.  Having meted out to Nachoragan the punishment usually assigned to unsuccessful commanders in Persia, he sent an ambassador to Byzantium in the spring of A.D. 556, and commenced negotiations which he intended to be serious.  Diplomacy seems to have been as averse in the days of Chosroes as in our own to an undignified rapidity of proceeding.  Hence, though there could be little to debate where both parties were substantially at one, the negotiations begun in May A.D. 556 were not concluded till after the commencement of the following year.  A complete suspension of hostilities was then agreed upon, to extend to Lazica no less than to the other dominions of the two monarchs.  In Lazica each party was to keep what it possessed, territory, cities, and castles.  As this joint occupation was scarcely suitable for a permanent arrangement, it was provided that the two belligerents should, during the continuance of the truce, proceed to settle the terms on which a lasting peace might be established.

An interval of five years elapsed before the happy result, for which both parties had expressed themselves anxious, was accomplished.  It is uncertain how Chosroes was occupied during this period; but there are some grounds for believing that he was engaged in the series of Oriental wars whereof we shall have to speak presently.  Success appears to have crowned his arms wherever he directed them; but he remained undazzled by his victories, and still retained the spirit of moderation which had led him in A.D. 557 to conclude the general truce.  He was even prepared, after five years of consideration, to go further in the line of pacific policy on which he had then entered, and, in order to secure the continuance of his good relations with Rome, was willing to relinquish all claim to the sovereignty of Lazica.  Under these circumstances, ambassadors of the highest rank, representing the two powers, met on the frontier between Daras and Nisibis, proclaimed the power and explained the motives of their respective sovereigns, and after a lengthy conference formulated a treaty of peace.  The terms, which are given at length by a writer of the succeeding generation, may be briefly expressed as follows:  (1) the Persians were to withdraw from Lazica, to give up all claim to it, and to hand over its possession to the Romans; (2) they were in return to receive from Rome an annual sum of 30,000 pieces of gold, the amount due for the first seven years being paid in advance; (3) the Christians in Persia were guaranteed the full and free exercise of their religion, but were forbidden to make converts
