In re-opening the case of the authorship of the Hellenica of Oxyrhynchus I am afraid I must state at once that you will find that there is not much in it, at least nothing new. The few pages, recently published by Vittorio Bartoletti, from a papyrus book which evidently contained the same work as P. Oxy. 842 (whether they belong to the same papyrus is therefore a secondary question) have not changed the state of the problem. They confirm (which is important, though not surprising) the two primary facts known about the author in question: (1) that he is a continuator of Thucydides—a fact which was inferred at once from the very exceptional use of Thucydides' war-year, and which, incidentally, does not allow of the further inference that he intended merely to complement Thucydides, ending his work with the fall of Athens, as it is often assumed that Xenophon originally did; (2) that he was the main source of Ephoros for the period for which Thucydides was no longer available. But, unfortunately, they do not contain a title-page or subscription; and it does not help that in the remains of col. ii the anonymous author seems to quote Thucydides. Quotations of prose writers by name are extremely rare in the fifth and even in the fourth century, but they do occur: Herodotus quotes Hekataios for a special point, and Thucydides quotes Hellanikos for a special period, though it is worth while mentioning that both quotations are polemical.
