Aria and Margiana are the most powerful districts in this part of Asia, these districts in part being enclosed by the mountains and in part having their habitations in the plains. Now the mountains are occupied by Tent-dwellers, and the plains are intersected by rivers that irrigate them, partly by the Arius and partly by the Margus. Aria borders on Margiana and . . . Bactriana;1
it is about six thousand stadia distant from Hyrcania. And Drangiana, as far as Carmania, was joined with Aria in the payment of tribute—Dragiana, for the most part, lying below the southern parts of the mountains, though some parts of it approach the northern region opposite Aria. But Arachosia, also, is not far away, this country too lying below the southern parts of the mountains and extending as far as the Indus River, being a part of Ariana. The length of Aria is about two thousand stadia, and the breadth of the plain about three hundred. Its cities are Artacaëna and Alexandreia and Achaïa, all named after their founders. The land is exceedingly productive of wine, which keeps good for three generations in vessels not smeared with pitch.
