The Parthians, who are now in possession of the empire of the East, having, as it were, divided the world with the Romans, came originally from Scythian exiles. This too is evident from their name: for in the Scythian language the word _Parthi_ signifies exiles. This nation, in the times both of the Assyrians and Medes, was the obscurest in the East. Afterwards too, when the empire of the East was transferred from the Medes to the Persians, they were an easy prey to the conquerors, like a vulgar herd without a name. At last, they came under the Macedonian yoke, when they carried their triumphant arms into these parts of the world; so that it is really strange that they should have arrived to such power as to rule over those nations, whose slaves they had formerly been. Being thrice attacked by the Romans, under the conduct of their greatest generals, in the most flourishing times of the republic, they alone of all nations were not only a match for them, but came off victorious; yet perhaps it was still a greater glory for them to be able to rise, amidst the Assyrian, Median, and Persian kingdoms, so famous of old, and the most opulent empire of Bactria, consisting of a thousand cities, than that they defeated a people that came from so remote a part of the world; especially when at that time they were incessantly alarmed by the Scythians and their other neighbours, and exposed to so many uncertainties of war. They being forced to leave Scythia by seditions at home did, by stealth, possess themselves of the deserts between Hyrcania, the Dahæ, the Arians, the Spartans, and Margians. After which, their neighbours not resisting at first, they at last, in spite of their opposition, when they came too late to hinder them, so far extended their frontiers that they not only took possession of vast plains, but also of craggy hills and steep mountains. And hence it comes that the heat and cold are excessive in several provinces of Parthia; for the snow is troublesome in the mountainous parts, and the heat in the plains.
