According to Strabo, the northern part of Drangiana was bordered both on the north and the west by Aria, whereas most Drangian territory extended south of the Parapamisus and was bordered on the west by Carmania, on the south by Gedrosia, and on the east by Arachosia.
The most detailed description, though riddled with errors, is that of Ptolemy (6.19), according to whom Drangiana was bounded in the west and north by Aria, in the east by Arachosia, and in the south by Gedrosia; a river, supposedly a branch of the Arabis, flowed through it.
Barsaë´nte@s, satrap of Arachosia and Drangiana, was one of the accomplices of the usurper Bessos (q.v.) against the last Achaemenid king, Darius III (q.v.; Arrian 3.21.1; cf.
His authority was challenged by a great many other pretenders and Greek dynasts in Sogdiana, Aria (Herat), Drangiana.
According to Apollodorus of Artemita, the historian of the Parthians, he ruled over 1000 towns (Strabo xv.
686; transferred to Diodotus of Bactria in Justin 41, 4.6); and the extent of his kingdom over Bactria, Sogdiana (Bokhara), Drangiana (Sijistan), Kabul and the western Punjab is confirmed by numerous coins.
