It is as well to be quite clear at once that the acquisition of this supremacy was not the work of one only of these peoples, the Latins, or of one city only of the Latins, _i.e._ Rome. It was the work of all these stocks which I have called native Italian. Roman is a convenient word, and Rome was all along the leader in action and the organising power; but the material, and in a great part as time went on the brain-power also, was contributed by all these peoples taken together. They had first to submit to the great leader and organiser, Rome, a fate against which, as we shall see, they struggled long; but no sooner had they submitted than they were added to the account of Italian development, and with few exceptions played their new part with a good courage. So much, then, for the Italian peoples who were to supersede the Greeks in the world’s history. But let us now return for a moment to the Tiber, and fix our eyes on the last five-and-twenty miles of its course, where it separates the plain of Latium from the Etruscan people to the north. The Latin-speaking stock were far more in danger from these Etruscans than the Umbrian and Samnite mountaineers; nothing but the river was between them and their enemies, for enemies they undoubtedly were, bent on pushing farther south, like the Danes in England in the ninth century of our era. The Latins had, indeed, a magnificent natural fortress in the middle of their plain, in the extinct volcano of the Alban mountain, some 3000 feet above sea-level; and here, according to a sure tradition, was their original chief city, Alba Longa. But this was of no avail against an invader from the north; it was the river that was the vital concern of Latium when once the Etruscans had become established to the north of it. Now at one point, some twenty miles by water from the river’s mouth, was a group of small hills, rising to a height of about 160 feet, three of them almost isolated and abutting on the stream, and the others in reality a part of the plain to the south, with their northern sides falling somewhat steeply towards the Tiber. Here, too, was an island in the river, which might give an enemy an easy chance of crossing. On this position there arose at some uncertain date, but beyond doubt as a fortress against the Etruscan power, a city called _Roma_; and there a city has been ever since, known by the same name. It is likely enough that it was an outpost founded by the city of Alba Longa, which eventually itself vanished out of history; and this was the tradition of later days. If we can accept the motive of the foundation—the defence of Latium against her foe, we need not trouble about the many legends of it.
