Arachosia bordered Drangiana to the west, Paropamisadae (i.e. Gandahara) to the north (a part of ancient India (present day Pakistan) to the east), and Gedrosia (or Dexendrusi) to the south. Isidore and Ptolemy (6.20.4-5) each provide a list of cities in Arachosia, among them (yet another) Alexandria, which lay on the river Arachotus. This city is frequently mis-identified with present-day Kandahar in Afghanistan, the name of which was thought to be derived (via "Iskanderiya") from "Alexandria", reflecting a connection to Alexander the Great's visit to the city on his campaign towards India. But a recent discovery of an inscription on a clay tablet has provided proof that 'Kandahar' was already a city that traded actively with Persia well before Alexander's time. Isidore, Strabo (11.8.9) and Pliny (6.61) also refer to the city as "metropolis of Arachosia."
