Note 395 — LIFE OF LUCULLUS.
George Long translation
Lucullus appears to have crossed the Euphrates at a more northern point than Zeugma, where the river was crossed by Crassus. Sophene is a district on the east side of the river between the mountain range called Masius and the range called Antitaurus: the capital or royal residence was Carcathiocerta. (Strabo, p. 527.)
