615 Despite some textual uncertainties (see Niese and Reinach), the main point is clear (cf. Ant. 1.159). Josephus reminds his readers of this fact again at 1.205, 214. If the book had a title it was perhaps On the Judeans ( περὶ ?Ιουδαίων); see Bar-Kochva 1996a: 182-91. Josephus’ delight that a Greek should be so impressed as to write a whole book on the Judeans is mirrored in the space accorded to Hecataeus (over one third of the Greek segment). Although Josephus probably believed it authentic, and a number of scholars have followed him, it is almost certain that the work here cited was written by a Judean (see Appendix 2). It appears to have taken up and corrected many of the observations on the Judeans in the digression on the topic by the real Hecataeus (known to us in the excerpt of Diodorus 40.3). It may have been structured as an ethnography (Jacoby 1943: 66-74; Bar-Kochva 1996a: 187-219), although Josephus’ selections hardly allow us to trace its shape and purpose. Its form (a first-hand account by a figure in the Ptolemaic court), its adulatory tone, and many of its topics (e.g., the magnificence of the temple) parallel Letter of Aristeas.
