The History of Rome

Here accordingly, along the narrow plateau above Palazzuola, between the Alban lake (Lago di Castello) and the Alban mount (Monte Cavo), extended the town of Alba, which was universally regarded as the primitive seat of the Latin stock, and the mother-city of Rome as well as of all the other Old Latin communities; here, too, on the slopes lay the very ancient Latin canton-centres of Lanuvium, Aricia, and Tusculum.  Here are found some of those primitive works of masonry, which usually mark the beginnings of civilization and seem to stand as a witness to posterity that in reality Pallas Athena when she does appear, comes into the world full grown. Such is the escarpment of the wall of rock below Alba in the direction of Palazzuola, whereby the place, which is rendered naturally inaccessible by the steep declivities of Monte Cavo on the south, is rendered equally unapproachable on the north, and only the two narrow approaches on the east and west, which are capable of being easily defended, are left open for traffic. Such, above all, is the large subterranean tunnel cut - so that a man can stand upright within it - through the hard wall of lava, 6000 feet thick, by which the waters of the lake formed in the old crater of the Alban Mount were reduced to their present level and a considerable space was gained for tillage on the mountain itself.

The summits of the last offshoots of the Sabine range form natural fastnesses of the Latin plain; and the canton-strongholds there gave rise at a later period to the considerable towns of Tibur and Praeneste. Labici too, Gabii, and Nomentum in the plain between the Alban and Sabine hills and the Tiber, Rome on the Tiber, Laurentum and Lavinium on the coast, were all more or less ancient centres of Latin colonization, not to speak of many others less famous and in some cases almost forgotten.
