[482] Curtius, vii. 5, 19. The exactness of Quintus Curtius, in describing the general features of Baktria and Sogdiana, is attested in the strongest language by modern travellers. See Burnes’s Travels into Bokhara, vol. ii. ch. 8. p. 211, 2nd edit.; also Morier, Second Journey in Persia, p. 282. But in the geographical details of the country, we are at fault. We have not sufficient data to identify more than one or two of the localities mentioned, in the narrative of Alexander’s proceedings, either by Curtius or Arrian. That Marakanda is the modern Samarkand—the river Polytimetus, the modern Kohik—and Baktra or Zariaspa the modern Balkh—appears certain; but the attempts made by commentators to assign the site of other places are not such as to carry conviction. In fact, these countries, at the present moment, are known only superficially as to their general scenery; for purposes of measurement and geography, they are almost unknown; as may be seen by any one who reads the Introduction to Erskine’s translation of the Memoirs of Sultan Baber. [483] Arrian. iii. 30, 5-10. These details are peculiarly authentic, as coming from Ptolemy, the person chiefly concerned. Aristobulus agreed in the description of the guise in which Bessus was exhibited, but stated that he was brought up in this way by Spitamenes and Dataphernes. Curtius (vii. 24, 36) follows this version. Diodorus also gives an account very like it, mentioning nothing about Ptolemy (xvii. 83).
