Viviene Gray examinesthe Hellenika not as an account of historical events, but as piece of historical writing. In it, she attempts to discover the mentality of the writer.

This book involves a new historiographical study of the Hellenica Oxyrhynchia that defines its relationship with fifth- and fourth-century historical works as well as its role as a source of Diodorus’ Bibliotheke. The traditional and common approach taken by those who studied the HO is primarily historical: scholars have focused on particular, often isolated, topics such as the question of the authorship, the historical perspective of the HO against other Hellenica from the 4th century BC. This book is unconventional in that it offers a study of the HO and fifth- and fourth-century historical works supported by papyrological enquiries and literary strategies, such as intertextuality and narratology, which will undoubtedly contribute to the progress of research in ancient historiography.

Here is a new edition of Xenophon's Hellenika, the primary source for the events of the final seven years and aftermath of the Peloponnesian War. --from publisher description.

The advances in Xenophontic studies of the last generation have still not resulted in a definitive literary treatment of the Hellenica 1-2, so Xenophon’s description of the Peloponnesian War deserves closer examination. This book aims to show that Xenophon has crafted his narrative in such a way as to reinforce the opinion of Thucydides, whose work he continued, that the development of the Peloponnesian War depended to a great extent on Persian money, but the factors that ultimately determined its outcome were the moral virtues and the skills of the military leaders of Athens and Sparta. Regarding Athens, Xenophon wants to show that despite Persia’s support of Sparta, Athens lost the war because of its troubled relationship with Alcibiades; the moral disintegration of the Athenians who condemned illegally the Arginousai generals and the appointment of generals who were greatly inferior. Concerning Sparta, Xenophon leads his readers to believe that in spite of- not because of- the interference of Persia in the Peloponnesian War the moral and military qualities of Lysander and Callicratidas were what turned the course of the war either in favor of or against Sparta in each phase of the war.
