The Roman History · Amm. 17.14.1

About this time Prosper and Spectatus and Eustathius, who, as has been mentioned above, had been sent as ambassadors to the Persians, found the Persian king at Ctesiphon, on his return from his campaign, and they delivered the emperor's letters and presents, and requested peace while affairs were still in their existing state. And mindful of what had been enjoined them, they never forgot the interests nor the dignity of the Roman empire, maintaining that the peace ought to be made on the condition that no alteration should be made in the state of Armenia or Mesopotamia.
