The traditions of what happened prior to the foundation of the City or whilst it was being built, are more fitted to adorn the creations of the poet than the authentic records of the historian, and I have no intention of establishing either their truth or their falsehood. This much licence is conceded to the ancients, that by intermingling human actions with divine they may confer a more august dignity on the origins of states. Now, if any nation ought to be allowed to claim a sacred origin and point back to a divine paternity that nation is Rome. For such is her renown in war that when she chooses to represent Mars as her own and her founder's father, the nations of the world accept the statement with the same equanimity with which they accept her dominion. But whatever opinions may be formed or criticisms passed upon these and similar traditions, I regard them as of small importance. The subjects to which I would ask each of my readers to devote his earnest attention are these-the life and morals of the community; the men and the qualities by which through domestic policy and foreign war dominion was won and extended. Then as the standard of morality gradually lowers, let him follow the decay of the national character, observing how at first it slowly sinks, then slips downward more and more rapidly, and finally begins to plunge into headlong ruin, until he reaches these days, in which we can bear neither our diseases nor their remedies.
There is this exceptionally beneficial and fruitful advantage to be derived from the study of the past, that you see, set in the clear light of historical truth, examples of every possible type. From these you may select for yourself and your country what to imitate, and also what, as being mischievous in its inception and disastrous in its issues, you are to avoid. Unless, however, I am misled by affection for my undertaking, there has never existed any commonwealth greater in power, with a purer morality, or more fertile in good examples; or any state in which avarice and luxury have been so late in making their inroads, or poverty and frugality so highly and continuously honoured, showing so clearly that the less wealth men possessed the less they coveted. In these latter years wealth has brought avarice in its train, and the unlimited command of pleasure has created in men a passion for ruining themselves and everything else through self-indulgence and licentiousness. But criticisms which will be unwelcome, even when perhaps necessary, must not appear in the commencement at all events of this extensive work. We should much prefer to start with favourable omens, and if we could have adopted the poets' custom, it would have been much pleasanter to commence with prayers and supplications to gods and goddesses that they would grant a favourable and successful issue to the great task before us.
Whether the task I have undertaken of writing a complete history of the Roman people from the very commencement of its existence will reward me for the labour spent on it, I neither know for certain, nor if I did know would I venture to say. For I see that this is an old-established and a common practice, each fresh writer being invariably persuaded that he will either attain greater certainty in the materials of his narrative, or surpass the rudeness of antiquity in the excellence of his style. However this may be, it will still be a great satisfaction to me to have taken my part, too, in investing, to the utmost of my abilities, the annals of the foremost nation in the world with a deeper interest; and if in such a crowd of writers my own reputation is thrown into the shade, I would console myself with the renown and greatness of those who eclipse my fame. The subject, moreover, is one that demands immense labour. It goes back beyond 700 years and, after starting from small and humble beginnings, has grown to such dimensions that it begins to be overburdened by its greatness. I have very little doubt, too, that for the majority of my readers the earliest times and those immediately succeeding, will possess little attraction; they will hurry on to these modern days in which the might of a long paramount nation is wasting by internal decay. I, on the other hand, shall look for a further reward of my labours in being able to close my eyes to the evils which our generation has witnessed for so many years; so long, at least, as I am devoting all my thoughts to retracing those pristine records, free from all the anxiety which can disturb the historian of his own times even if it cannot warp him from the truth.
