but under Vespasian a Roman garrison was stationed beyond the Armenian frontier in the Iberian fortress Harmozika near Tiflis,[43] and accordingly at this time Armenia also must have been militarily in the Roman power. All these measures, however little they contained even a threat of war, were pointed against the eastern neighbour. Nevertheless Vologasus was after the fall of Jerusalem the first to offer to the Roman crown-prince his congratulations on the strengthening of the Roman rule in Syria, and he accepted without remonstrance the encampment of the legions in Commagene, Cappadocia, and Lesser Armenia. Nay, he even once more incited Vespasian to that Transcaucasian expedition, and besought the sending of a Roman army against the Alani under the leadership of one of the imperial princes; although Vespasian did not enter into this far-seeing plan, that Roman force can hardly have been sent into the region of Tiflis for any other object than for closing the pass of the Caucasus, and in so far it represented there also the interests of the Parthians. In spite of the strengthening of the military position of Rome on the Euphrates, or even perhaps in consequence of it--for to instil respect into a neighbour is a means of preserving the peace--the state of peace remained essentially undisturbed during the whole rule of the Flavians. If--as cannot be surprising, especially when we consider the constant change of the Parthian dynasts--collisions now and then occurred, and war-clouds even made their appearance, they disappeared again as quickly.[44] The emergence of a pseudo-Nero in the last years of Vespasian--he it was who gave the impulse to the Revelation of John--might almost have led to such a collision. The pretender, in reality a certain Terentius Maximus from Asia Minor, but strikingly resembling the poet-emperor in face, voice, and address, found not merely a conflux of adherents in the Roman region of the Euphrates, but also support among the Parthians. Among these at that time, as so often, several rulers seem to have been in conflict with each other, and one of them, Artabanus, because the emperor Titus declared against him, seems to have adopted the cause of the Roman pretender. This, however, had no consequences; on the contrary, soon afterwards the Parthian government delivered up the pretender to the emperor Domitian.[45] The commercial intercourse, advantageous for both parties between Syria and the lower Euphrates, where just then king Vologasus called into existence the new emporium Vologasias or Vologasocerta, not far from Ctesiphon, must have contributed its part towards promoting the state of peace.
