The few grains of truth that we are able to sift from the mass of legend which has accumulated round the early history of Rome seem to indicate that at a very early period--which the generally received date of 753 B.C. may be taken to fix as nearly as is now possible--a small band of outcasts and marauders settled themselves on the Palatine Hill and commenced to carry on depredations against the various cities of the tribes whose territories were in the immediate neighbourhood, such as the Umbrians, Sabines, Samnites, Latins, and Etruscans. A walled city was built, which from its admirable situation succeeded in attracting inhabitants in considerable numbers, and speedily began to exercise supremacy over its neighbours. The most important of the neighbouring nations were the Etruscans, who called themselves Rasena, and who must have settled on the west coast of Italy, between the rivers Arno and Tiber, at a very early period. Their origin is, however, very obscure, some authorities believing, upon apparently good grounds, that they came from Asia Minor, while others assert that they descended from the north over the Rhætian Alps. But whatever that origin may have been, they had at the time of the founding of Rome as a city attained a high degree of civilisation, and showed a considerable amount of architectural skill; and their arts exercised a very great influence upon Roman art. Considerable remains of the city walls of several Etruscan towns still exist. These show that the masonry was of what has been termed a Cyclopean character,--that is to say, the separate stones were of an enormous size; in the majority of examples these stones were of a polygonal shape, though in a few instances they were rectangular, while in all cases they were fitted together with the most consummate accuracy of workmanship, which, together with their great massiveness, has enabled much of this masonry to endure to the present day. Cortona, Volterra, Fiesole, and other towns exhibit instances of this walling. The temples, palaces, or dwelling-houses which went to make up the cities so fortified have all disappeared, and the only existing structural remains of Etruscan buildings are tombs. These are found in large numbers, and consist--as in the earlier instances which have already been described--both of rock-cut and detached erections. Of the former, the best known group is at Castel d'Asso, where we find not only chambers cut into the rock, each resembling an ordinary room with an entrance in the face of the rock, but also monuments cut completely out and standing clear all round; and we cannot fail to detect in the forms into which the rock has been cut, especially those of the roof, imitations of wooden buildings, heavy square piers being left at intervals supporting longitudinal beams which hold up the roof. Fig. 122 is an illustration of the interior of a chamber in the rock. Occasionally there were a cornice and pediment over the entrance.
