While P's identity has been debated extensively by modern scholars, a consensus has not been achieved. Among the authors suggested at early stages have been prominent historians such as Ephorus and Theopompus,[5] although most of these have been strongly objected to on grounds of style, presentation, or subject matter. The most likely candidate seems to be Cratippus, an Athenian historian of the 4th century BCE.[6] The style, biases, and coverage (Cratippus's work is known to have been a continuation of Thucydides) support the identification, although issues have been raised.[3] Bruno Bleckmann, an expert on ancient historiography, has pleaded again for Theopompus as the author of the Hellenica.[7]
