I will also assume that those who have begun to read this book are provided with some knowledge of that Mediterranean basin which is the scene of Græco-Roman history; such as can be gained by frequent contemplation of a good map. They will be familiar with Sicily and south Italy, which were teeming with Greek settlements when Roman history really begins. They will probably have realised how short a step it is from Italy to Africa, whether or no Sicily be taken as a stepping-stone; Cato could show fresh figs in the Roman senate which had been grown in Carthaginian territory. They will have realised that you can pass from the “heel” of Italy to the Hellenic peninsula in a single night, as Cæsar did when he embarked his army at Brindisi to attack his rival; such geographical facts are of immense importance in explaining not only the foreign policy of Rome, but also the development of her culture. And thus furnished, they will begin to be curious about the destiny of the Italian peninsula, of which Greek history has had little to tell them. Leaving that question for the present, they will wish to know why the Greeks did not colonise the centre and north of Italy as they did the south and south-west, but left room enough for a new type of civilisation to grow up there. And above all, they will wish to know how and why a single city on the western coast should have succeeded in building up a great power in Italy quite independent of Greece, and destined eventually to supersede her, which may be reckoned as a factor almost as important in the making of our modern civilisation as Hellas herself. This last question is the one which I must try to answer in the earlier part of this book; in the later chapters I shall have to deal with another one—how this single city-state contrived to weld together the whole Mediterranean civilisation, strongly enough to give it several centuries of security against uncivilised enemies in the north, and half-civilised enemies in the east. But for the moment let us see why the Greeks did not permeate Italy with their own civilisation as they did Sicily: how it was that they left room for a new power, capable eventually of shielding them and their work from destruction. To answer this question we must consider the nature of the Italian peninsula, and the character of the races then living in it.
