In an aside to his audience after narrating the revolt of the Theruingi and the slaughter of the Roman army under Lupicinus in AD 376, the ’lonely’ historian Ammianus Marcellinus asks the indulgence of his readers on a particularly difficult matter ... The rather poignant parenthesis is consistent with the view that Ammianus presents elsewhere in his history of a public at Rome concerned only with the trivial biographies of emperors and caring more for the details of the private lives of the imperial household than with the grand sweep of res gestae. The last antique historian is indeed a great one, and he may even have been as isolated as is sometimes suggested.

Up to this point our concern has been how the ancient historian justifies himself before his audience and attempts to portray himself as the proper person for the writing of history, that is, with his role as narrator rerum. The present chapter examines how he approaches his task when a participant in the deeds he records, and how he reconciles the dual role of actor and auctor rerum. For many historians of the ancient world had the opportunity to be both participant and rememberer. The historian’s formal method of presenting himself has received comparatively little attention, yet it is of interest not only because it tells us something of the way that men who wrote history in the ancient world approached the writing of their own deeds, but also what their concerns were in doing so. It is usually assumed that in order to give authority to his account, an historian who narrated his own deeds used the third person and maintained a show of formal impartiality. But a study of the surviving (and partially surviving) historians reveals a variety of approaches and methods, changing with time, the specific type of history written, and the individual intention of the historian himself.

The historian’s task is to narrate, but he must also win credibility for that narrative: his task is therefore also to persuade his audience that he is the proper person to tell the story and, moreover, that his account is one that should be believed. In his capacity as persuader, the historian will often try to shape the audience’s perception of his character and to use this as an additional claim to authority; indeed, among the Roman historians, where explicit professions of research are rarer than with the Greeks, the shaping of the narrator’s character takes on a correspondingly larger role. But most of the historians, Greek and Roman, try to shape their audience’s perception of their character. Nor is this surprising when we consider the teachings of rhetoric.

At the court of the Phaeacians, Demodocus sings of the quarrel between Odysseus and Achilles and delights his listeners, all except the still unrevealed Odysseus who covers his head and weeps. During the feast that follows, Odysseus, despite his grief, sends the singer a rich portion of meat and salutes him, praising how well he sang ’all that the Achaeans did and suffered and toiled, as if you were present yourself, or heard it from one who was’. In this simile, Odysseus anticipates the twin methods of validation for contemporary historians: eyewitness (autopsy) and inquiry of the participants in events. In ancient historiography, professions of autopsy and inquiry are found from Herodotus to Ammianus, and they serve as one of the most prominent means of claiming the authority to narrate contemporary and non-contemporary history. In this chapter, we shall survey some of the issues revolving around inquiry for ancient historians, treating the theoretical observations of the historians on the difficulties and problems raised by inquiry, as well as the explicit claims made by historians in the course of their narratives.

Although I have regularly cited Authority and Tradition in Ancient Historiography in the twenty-five years or so since it appeared, it is only with the current reissue of the work that I have gone back and read it through from beginning to end. About ten years after it was published, I gave serious thought to writing a revised version, both to incorporate much material that I had left out of the original and also (naturally) to update it in the light of more recent scholarship. In the end, I decided not to do so, mostly from the belief that scholarship is an ongoing conversation, and that a work, once published, becomes part of that conversation, dependent on its time and context. Authority and Tradition appeared at a particular point in the discussion of the nature of Greco-Roman historiography, when the linguistic and literary turn was becoming more and more prominent, and the book reflects that moment.

Our study has concentrated on the explicit attempts by the ancient historians to convince the reader of their authority to narrate deeds, and to portray themselves as believable narrators of those deeds. We have seen how the dictates of ancient literary criticism enjoined authors to work within a tradition, and to show their innovation within that tradition. As certain historians became accepted models for imitation, their concerns and approach dictated for those who followed the proper way to write history. As the earlier historians were ’authoritative’, so their followers sought to imitate the manner by which those predecessors had constructed their own authority. It was in this way that authority and tradition were closely related, and so long as the belief in imitation held sway, there could be no authority outside of tradition.

This book is a study of the explicit attempts by the ancient Greek and Roman historians to claim the authority to narrate the deeds encompassed in their works. The term ’authority’ has many meanings over a range of disciplines, but in this book it is used to refer to literary authority, the rhetorical means by which the ancient historian claims the competence to narrate and explain the past, and simultaneously constructs a persona that the audience will find persuasive and believable. The work is thus a study of certain forms and conventions of persuasion employed by the historians. No attempt is made to evaluate the truth or falsity of historians’ claims; rather, I try to set out the various claims which are part of the construction of the author’s historiographical persona; to see how and why these claims are made; to explain how the tradition of such claims developed; and to show how the tradition moulded the way in which writers claimed historiographical authority.

Most of the ancient historians give some indication to their audience why they embarked upon writing their history. These remarks sometimes concern themselves with the unique nature of the historian’s subject matter; in addition to the greatness of the deeds, historians will frequently explain other circumstances that led them to the composition of their histories. There is, in general, a tendency as time goes on for authors, while not abandoning the magnification of their theme, to present a more ’personal’ call to history, that is, to say something of themselves and the personal experiences that underlay their writing of history.
