 Julian was killed by the enemy in a skirmish during his retreat back to Roman territory.His successor Jovian (363–364) made an ignominious peace in which the districts beyond the Tigris which had been acquired in 298 were given to the Persians along with Nisibis and Singara, and the Romans promised to interfere no more in Armenia.The great success is represented in the rock-sculptures near the town Bishapur in Pars (Stolze, "Persepolis", p. 141); under the hooves of the king's horse lies the body of an enemy, probably Julian, and a supplicant Roman, the Emperor Jovian, asks for peace.
