Note 153 — Chapter LXX · RETREAT OF THE TEN THOUSAND GREEKS.

Xen. Anab. ii, 5, 1. Ainsworth. Travels and Researches in Asia Minor, etc. vol. ii, ch. 44, p. 327; also his Travels in the Track of the Ten Thousand, p. 119-134.

Professor Koch, who speaks with personal knowledge both of Armenia and of the region east of the Tigris, observes truly that the Great Zab is the only point (east of the Tigris) which Xenophon assigns in such a manner as to be capable of distinct local identification. He also observes, here as elsewhere, that the number of parasangs specified by Xenophon is essentially delusive as a measure of distance (Zug der Zehn Tausend, p. 64).
