Sir John Malcolm observes—“There can hardly be said to be any roads in Persia; nor are they much required, for the use of wheel carriages has not yet been introduced into that kingdom. Nothing can be more rugged and difficult than the paths which have been cut over the mountains by which it is bounded and intersected” (ch. xxiv. vol. ii. p. 525).

In this respect, indeed, as in others, the modern state of Persia must be inferior to the ancient; witness the description given by Herodotus of the road between Sardis and Susa.

[433] Arrian, iii. 19, 14; Diodor. xvii. 80. Diodorus had before stated (xvii. 66, 71) the treasure in Susa as being 49,000 talents, and that in Persepolis as 120,000. Arrian announces the treasure in Susa as 50,000 talents—Curtius gives the uncoined gold and silver alone as 50,000 talents (v. 8, 11). The treasure of both places was transported to Ekbatana.

See the remarks of Rüstow and Köchly upon the change made by Alexander in his military organization about this period, as soon as he found that there was no farther chance of a large collected Persian force, able to meet him in the field (Geschichte des Griech. Kriegswesens, p. 252 seq.).
