THE MEDIAEVAL MIND
BOOK I

of the Peloponnesian War, that masterpiece of reasoned statement, was not over-anxious as to accuracy of actual word and fact reported. He carefully inquired regarding the events, in some of which he had been an actor. Often he knew or ascertained what the chief speakers said in those dramatic situations which kept arising in this war of neighbours. Yet, instead of reporting actual words, he gives the sentiments which, according to the laws of rhetorical probability, they must have uttered. So he presents the psychology and turning-point of the matter.

This was true historical rhetoric; the historian's art of setting forth a situation veritably, by presenting its intrinsic necessities. Xenophon's Cyropaedia went a step farther; it was a historical romance, which neither followed fact nor proceeded according to the necessities of the actual situation. But it did proceed according to moral proprieties, and so was edifying and plausible.

The classical Latin practice accorded with the Greek. Cicero speaks of history as opus oratorium, that is, a work having rhetorical and literary qualities. It should set forth the events and situations according to their inherent necessities which constitute their rhetorical truth. Then it should possess the civic and social qualities of good oratory: morals and public utility. These are, in fact, the characteristics of the works of Sallust, Livy, and Tacitus. None of them troubled himself much over an accuracy of detail irrelevant to his larger purpose. Tacitus is interested in memorable facts; he would relate them in such form that they might carry their lesson, and bear their part in the education of the citizen, for whom it is salutary to study the past. He condemns, indeed, the historians of the Empire who, under an evil emperor, lie from fear, and, upon his death, lie from hate. But such condemnation of immoral lying does not forbid the shaping of a story according to artistic probability and moral ends. Some shaping and adorning of fact might be allowed the historian, acting with motives of public policy, or seeking to glorify or defend his country.[1] This quite accords with the view of Varro and Cicero, that good policy should sometimes outweigh truth:
