As one goes from Citharizon[59] towards Theodosiopolis and Greater Armenia is the country of Corzane, which extends for a distance of about three days’ journey, without any lake, river or mountain to divide it from the country of the Persians, whose frontier is confused with it; so that the inhabitants of this region, whether they be Roman or Persian subjects, have no fear of one another, and never expect any attack, but intermarry with one another, have common markets for their produce, and cultivate the country together. When the rulers of either nation make an expedition against the other at the command of their prince, they always find their neighbours unprotected; for each of them has extremely populous places close to one another, while in former times there was no fortification whatever; so that it was possible for the King of Persia to invade the Roman territory in this quarter more easily than anywhere else, until the Emperor Justinian prevented his doing so, in the following manner. In the midst of this country there was a place named Artaleson, which he surrounded with a very strong wall, and made into an impregnable fortress; he placed a garrison of regular soldiers in it, and appointed a general over them, whom the Romans in the Latin language style ‘a Duke.’ Thus did he fortify the whole of that frontier. IV. These were the works of the Emperor Justinian in that quarter. I now come to what he did in the rest of Armenia. The city of Satala was formerly in a perilous position, because it is not far distant from the enemy’s country, and is built upon low ground, surrounded by many hills, so that it ought in consequence of its position to possess impregnable fortifications. However, its defences were even more untrustworthy than its position, the works having been badly and carelessly constructed, and by lapse of time having fallen into ruin. The whole of these were demolished by the Emperor, who built a new wall round it of sufficient height to appear to overtop the neighbouring hills, and of sufficient thickness to support such an unusual height with safety. He built round it an outwork of an admirable character, and struck despair into the heart of the enemy. He also built a very strong fort not far from Satala, in the province of Osrhoene.
