Note 411 — Chapter XCIII · SECOND AND THIRD ASIATIC CAMPAIGNS OF ALEXANDER — BATTLE OF ISSUS — SIEGE OF TYRE. (continued 2)
Reading edition
Arrian, iii. 17, 1. Ἄρας δὲ ἐκ Σούσων, καὶ διαβὰς τὸν Πασιτίγρην ποταμὸν, ἐμβάλλει εἰς τὴν Οὐξίων γῆν.
The Persian Susa was situated between two rivers; the Choaspes (now Kherkha) on the west; the Eulæus or Pasitigris, now Karun, on the east; both rivers distinguished for excellent water. The Eulæus appears to have been called Pasitigris in the lower part of its course—Pliny, H. N. xxxi. 21. “Parthorum reges ex Choaspe et Eulæo tantum bibunt.”
Ritter has given an elaborate exposition respecting these two rivers and the site of the Persian Susa (Erdkunde, part ix. book iii. West-Asien, p. 291-320).
