Cassius Dio (155 – 235 AD). “[Resolving matters in Armenia], he [Pompey] overwintered in the Anahitida district (in Akilisen) and near the Kournas River, dividing the troops into three [parts] and receiving from Tigran many different [supplies] and money, much more than the set [amount]. However, he did not manage to spend the winter quietly because Oroz, the king of the Albanians who lived above Kournas, went against them at the very beginning of [holiday] Cronius.”
Cassius Dio, XXXVI, 53, 5; 54, 1.
Pavstos Buzand (5th century AD) “On the robber raid of the Maskut King on the land subject to the Armenian King, on the great war that took place, and on how he died together with his army.
At that time, the Maskut king Sanesan was filled with enmity towards his brother, Armenian King Khosrov. And he gathered all the troops – the Huns, Pokhs, Tavaspars, Hechmataks, Izhmahs, Gatovs, Gluars, Gugars, Shichbians, Chilbs, Balasiches, Yegersvans, and a great many other disparate nomadic tribes, all the multitude of troops that he commanded. He crossed his frontier, the great Kur River, and overran the Armenian country.”
Book III, Chapter VII
“On how the Armenian kingdom collapsed, on how many of the Armenian Nakharars rebelled and sided with the Persian king Shapur, and on how the Armenian kingdom soon dispersed in different directions and thinned.
For thirty-four years, our Armenian country has fought against the Persian king. Then, both sides got exhausted, suffered defeat, and lost heart. Decomposition began in the camp of the Armenian king – people began to leave their king Arshak, and this decomposition began with the great nobles. First were the bdeshkh [province ruler] of Aghdznik and bdeshkh of Noshirakan…
After this, the bdeshkh of Gugark and after him the ruler of the Dzor district, the ruler of the Kolb district, with them also the ruler of Gardmanadzor, and all those who were in these lands around them rebelled against the Armenian King Arshak and went and appeared before the Persian King Shapur. The fortified Artsakh district, the fortified Tmorik district, and the fortified Kordik district also rose against the Armenian King Arshak…
After that, the Armenian domain of the Armenian royal house in the country of Atrapatakan also separated from the Armenian King… And the [Armenian] kingdom was greatly shaken…”

Then, when the war against the Persians ended and [Armenians] were secured from this side, the Armenian Sparapet Mushegh began to smash those who had rebelled against the Arshakuni Kingdom. First, he conquered the possessions of the Armenian King in Atrapatakan…”

“On the Iberians.
Then, Sparapet Mushegh went to the Iberian king… And seizing the territory up until the old border, which had been between Armenia and Iberia, that is, had been the great Kur River, he returned.”
