The geographical position of the tribes is as follows: along the Indus are the Paropamisadae, above whom lies the Paropamisus mountain; then, towards the south, the Arachoti; then next, towards the south, the Gedroseni, with the other tribes that occupy the seabord; and the Indus lies, latitudinally, alongside these places; and of these places, in part, some that lie along the Indus are held by Indians, although they formerly belonged to the Persians. Alexander took these away from the Arians and established settlements of his own, but Seleucus I Nicator gave them to Sandrocottus, upon terms of intermarriage and of receiving in exchange 500 elephants.
