Mithridates, the Iberian, was left in quiet possession of the Armenian kingdom, and Vitellius found himself unmolested on the Euphrates.

Tiberius, however, was anxious that the war with Parthia should be formally terminated, and, having failed in his attempts to fill the Parthian throne with a Roman nominee, was ready to acknowledge Artabanus, and eager to enter into a treaty with him.

He instructed Vitellius to this effect; and that officer (late in A.D.36 or early in A.D.

37), having invited Artabanus to an interview on the Euphrates, persuaded him to terms which were regarded by the Romans as highly honorable to themselves, though Artabanus probably did not feel them to be degrading to Parthia.

Peace and amity were re-established between the two nations.
