The Roman legions, defeated and humiliated, were forced to pass under the yoke of Armenian spears, a deeply symbolic and degrading punishment for any soldier.

The agreement also marked a significant diplomatic compromise, as Tiridates I agreed to receive his crown from the Roman emperor Nero, symbolizing a fragile balance of power between Rome and Parthia in the region.

[7] Paetus nonetheless appeared confident of victory, and followed the Parthian declaration of war and capture of Tigranocerta with his own invasion of Armenia,[8] while Corbulo remained at Syria, further strengthening the fortifications in the Euphrates frontier.

[8] Corbulo in the meantime had been aware of the danger faced by his colleague, and put part of his forces on standby, but he did not march to join Paetus, and some accused him of delaying in order to reap more glory from rescuing him.

[8] The subsequent treaty was humiliating: not only would the Romans leave Armenia and surrender all forts they held, but they also agreed to build a bridge over the nearby Arsanias river over which Vologases could pass in triumph, sitting atop an elephant.

[12][13] The two Roman forces met on the banks of the Euphrates near Melitene, amidst scenes of mutual grief;[14] while Corbulo lamented the undoing of his achievements, Paetus tried to convince him to attempt to reverse the situation by invading Armenia.
