Their principal neighljor on one side was Etruria, a Pelasgian nation. On the other hand was Magna Graecia, which had been colonized in very early ages by Hellenic settlers of kindred origin. It was therefore impossible that the archi- tecture of the Romans should not be in fact a mixture of the styles of these two people. As a transition order, it was only a mechanical juxtaposition of both styles, the real fusion taking place many long centuries afterwards. Throughotit the Roman period the two styles remain distinct, and there is no great difficulty in referring almost every feature in Roman architecture to its origin. From the Greeks were borrowed the rectangular ])eristylar temple, with its columns and horizontal architraves, though they seldom if ever used it in its perfect purity, the cella of the Greek tem])les not being sufficiently large for their purposes. The principal Etruscan temples, as we have already shown, were square in plan, and the inner half occupied by one or more cells, to the sides and back of which the portico never extended. The Roman rectangular temple is a mixture of these two : it is generally, like the Greek exam])les, longer than its breadth, but the colonnade never seems to have entirely surrounded the building. Sometimes it extends to the two sides as well as the front,
