Strabo, Geography

Such, indeed, is the size and such the character of Italy. And while I have already mentioned many things which have caused the Romans at the present time to be exalted to so great a height, I shall now indicate the most important things. One is, that, like an island, Italy is securely guarded by the seas on all sides, except in a few regions, and even these are fortified by mountains that are hardly passable. A second is that along most of its coast it is harborless and that the harbors it does have are large and admirable. The former is useful in meeting attacks from the outside, while the latter is helpful in making counter-attacks and in promoting an abundant commerce. A third is that it is characterized by many differences of air and temperature, on which depend the greater variation, whether for better or for worse, in animals, plants, and, in short, everything that is useful for the support of life.¹ Its length extends from north to south, generally speaking, and Sicily counts as an addition to its length, already so great. Now mild temperature and harsh temperature of the air are judged by heat, cold, and their intermediates;² and so from this it necessarily follows that what is now Italy, situated as it is between the two extremes and extending to such a length, shares very largely in the temperate zone and in a very large number of ways. And the following is still another advantage which has fallen to the lot of Italy; since the Apennine Mountains extend through the whole of its length and leave on both sides plains and hills which bear fine fruits, there is no part of it which does not enjoy the blessings of both mountain and plain. And add also to this the size and number of its rivers and its lakes, and, besides these, the fountains of water, both hot and cold, which in many places nature has provided as an aid to health, and then again its good supply of mines of all sorts. Neither can one worthily describe Italy's abundant supply of fuel, and of food both for men and beast, and the excellence of its fruits. Further, since it lies intermediate between the largest races³ on the one hand, and Greece and the best parts of Libya on the other, it not only is naturally well-suited to hegemony, because it surpasses the countries that surround it both in the valor of its people and in size, but also can easily avail itself of their services, because it is close to them.
