Note 4 — Chapter I

The Euphrates, which Diodorus mentions 2, 3 and also 2, 27, is not to be put down to a mistake of Ctesias, since Nicolaus (Frag. 9, ed. Müller) describes Nineveh as situated on the Tigris in a passage undoubtedly borrowed from Ctesias. The error belongs, as Carl Jacoby ("Rhein. Museum," 30, 575 ff.) has proved, to the historians of the time of Alexander and the earliest Diadochi, who had in their thoughts the city of Mabog (Hierapolis), on the Euphrates, which was also called Nineveh. The mistake has passed from Clitarchus to the narrative of Diodorus.
