De Imperio Cn. Pompei Ad Quirites

In this alarm and flight of his, Tigranes, the king of Armenia, received him, encouraged him while despairing of his fortunes, gave him new spirit in his depression, and recruited with new strength his powerless condition. And after Lucius Lucullus arrived in his kingdom, very many tribes were excited to hostilities against our general. For those nations which the Roman people never had thought either of attacking in war or tampering with, had been inspired with fear. There was, besides, a general opinion which had taken deep root, and had spread over all the barbarian tribes in those districts, that our army had been led into those countries with the object of plundering a very wealthy and most religiously worshipped temple. And so, many powerful nations were roused against us by a fresh dread and alarm. But our army although it had taken a city of Tigranes's kingdom, and had fought some successful battles, still was out of spirits at its immense distance from Rome, and its separation from its friends.
