Ancient history divides itself into the history anterior to the rule of Rome, which has many centres, and into the history of Roman rule, wherein there is but one centre, Rome, the action of which extends on all sides. Other nations, like the Egyptians, have acted by their intellectual power upon the foreigner, but were deficient in mind; others, as the barbarian nations of the Celts and other races, became important merely by the mightiness of their conquests; Greece, by her mind; but Rome combines every thing, the greatest political perfection, might, and mind. Here is an influence which has become still more lasting and ineffaceable than that of Greece: it continues to the latest centuries, even to this very day. The Roman history has to exhibit the greatest characters, achievements, and events; it is the development of the whole life of a people, the like of which is unknown in all the rest of history. Of the history of the East, as far as regards the stages of its progress, we know nothing whatever. The Egyptians we find already in castes, consequently in fixed forms, in which they abide throughout every century; they exist unalterable, of which their mummies are the emblem, and all the changes which we remark in them are a mere dying away. The Romans we see almost growing under our eyes; indeed, they also are early moulded into fixed forms, but their origin is no riddle to us. The other nations are as buds still folded up in their petals; they grow, but before they expand, they die away or only open imperfectly, as it also ever occurs with individuals, that among many thousands few only are not checked in their development. In modern history the English alone have had a career like that of the Romans. In a cosmopolitical point of view therefore, these two histories must ever remain the most important ones. Here now the whole history of the twelve ages, which in the legend of Romulus have also been foretold as the duration of Rome, is to be set forth;--in the beginning the history of the nation and the town, then that of the empire and the aggregate of people who bore the name of Romans. But first of all, let us make ourselves acquainted with the sources. SOURCES OF ROMAN HISTORY.
