Note 1 — Chapter I

Cf. Hogarth, "The Nearer East," pp. 212 ff., and Ramsay, "The Historical Geography of Asia Minor," pp. 27 ff. Herodotus (V, 52-54) describes the "Royal Road" of the Persian period as passing from Ephesus by the Cilician Gates to Susa, and it obtained its name from the fact that all government business of the Persian Court passed along it; the distances, given by Herodotus in parasangs and stages, may well be derived from some official Persian document (cf. How and Wells, "Commentary on Herodotus," II, p. 21). But it followed the track of a still earlier Royal Road, by which Khatti, the capital of the old Hittite Empire, maintained its communications westward and with the Euphrates valley.
