The breadth of the country is the length of the Indus, reckoned from the Paropamisus as far as the mouths of that river, and amounts to 12,000, or according to others to 13,000, stadia. The length, beginning from the Caspian Gates, as it is laid down in Asiatic Stathmi,[423] is estimated in two different ways. From the Caspian Gates to Alexandreia among the Arii[424] through Parthia is one and the same road. Then a road leads in a straight line through Bactriana, and over the pass of the mountain to Ortospana,[425] to the meeting of the three roads from Bactra, which is among the Paropamisadæ. The other branch turns off a little from Aria towards the south to Prophthasia in Drangiana; then the remainder leads as far as the confines of India and of the Indus; so that the road through the Drangæ and the Arachoti is longer, the whole amounting to 15,300 stadia. But if we deduct 1300 stadia, we shall have the remainder as the length of the country in a straight line, namely, 14,000 stadia; for the length of the coast is not much less, although some persons increase this sum by adding to the 10,000 stadia Carmania, which is reckoned at 6000 stadia. For they seem to reckon it either together with the gulfs, or together with the Carmanian coast within the Persian Gulf. The name also of Ariana is extended so as to include some part of Persia, Media, and the north of Bactria and Sogdiana; for these nations speak nearly the same language.[426] 9. The order in which these nations are disposed is as follows. Along the Indus are the Paropamisadæ, above whom lies the mountain Paropamisus; then towards the south are the Arachoti; then next to these towards the south, the Gedroseni, together with other tribes who occupy the sea-coast; the Indus runs parallel along the breadth of these tracts. The Indians occupy [in part][427] some of the countries situated along the Indus, which formerly belonged to the Persians: Alexander deprived the Ariani of them, and established there settlements of his own. But Seleucus Nicator gave them to Sandrocottus in consequence of a marriage contract, and received in return five hundred elephants. The Arii are situated on the west, by the side of the Paropamisadæ and the Drangæ[428] by the Arachoti and Gedrosii. The Arii are situated by the side of the Drangæ both on the north and west, and nearly encompass them. Bactriana adjoins Aria on the north, and the Paropamisadæ, through whose territory Alexander passed when he crossed the Caucasus on his way to Bactra. Towards the west, next to the Arii, are the Parthians, and the parts about the Caspian Gates. Towards the south of Parthia is the desert of Carmania; then follows the remainder of Carmania and Gedrosia.
