[-24-] During the remainder of winter, when Gallus and Nerva were holding office, Publius Canidius Crassus made a campaign against the Iberians that inhabit this portion of the world, conquered in battle their king Pharnabazus and brought them into alliance; with this king he invaded Albanis, the adjoining country, and, after overcoming the dwellers there and their king Zober, conciliated them likewise. Antony was elated at this and furthermore based great hopes upon Monaeses, who had promised him to lead his army and bring over to him most of Parthia without conflict. Hence the Roman took up the war against the Parthians in earnest and besides making various presents to Monaeses gave him three Roman cities to govern until he should finish the war, and promised him in addition the Parthian kingdom. While they were so occupied Phraates became terrified, especially because the Parthians took the flight of Monaeses very much amiss, and he opened negotiations with him, offering him anything whatever, and so persuaded him to return. When Antony found this out, he was naturally angry, but did not kill Monaeses although the latter was still in his power; for he felt sure he could not win the confidence of any other of the barbarians, in case he should do such a thing, and he wanted to try a little trick against them. He accordingly released Monaeses, apparently supposing the latter was going to bring the Parthian affairs under his control, and sent envoys with him to Phraates. Nominally he was arranging for peace on the condition of getting back the standards and the prisoners captured in the disaster of Crassus, intending to take the king off his guard while the latter was expecting a pacific settlement; but in fact he was putting everything in readiness for war. [-25-] And he went as far as the Euphrates, thinking it was free of guards. When, however, he found that whole region carefully guarded, he turned aside from it, but led a campaign against Artavasdes, the king of the Medes, persuaded thereto by the king of Greater Armenia, who had the same name and was an enemy of the aforementioned. Just as he was he at once advanced toward Armenia, and learning there that the Mede had gone a considerable distance from his own land in the discharge of his duties as an ally of the Parthian king, he left behind the beasts of burden and a portion of the army with Oppius Statianus, giving orders for them to follow, and himself taking the cavalry and the strongest of the infantry hurried on in the confidence of seizing all his opponent's strongholds at one blow; he assailed Praaspa, the royal residence, heaped up mounds and made constant attacks. When the Parthian and the Medan kings ascertained this, they left him to continue his idle toil,--for the walls were strong and many were defending them,--but assailed Statianus off his guard and wearied on the march and slew the whole detachment except Polemon, king of Pontus, who was then accompanying the expedition.
