The connexion of these feuds with Dante's poem has given to the middle age history of Italy an interest of which it is not undeserving in itself, full as it is of curious exhibitions of character and contrivance, but to which politically it cannot lay claim, amid the social phenomena, so far grander in scale and purpose and more felicitous in issue, of the other western nations. It is remarkable for keeping up an antique phase, which, in spite of modern arrangements, it has not yet lost. It is a history of cities. In ancient history all that is most memorable and instructive gathers round cities; civilisation and empire were concentrated within walls; and it baffled the ancient mind to conceive how power should be possessed and wielded, by numbers larger than might be collected in a single market-place. The Roman Empire indeed aimed at being one in its administration and law; but it was not a nation, nor were its provinces nations. Yet everywhere but in Italy, it prepared them for becoming nations. And while everywhere else parts were uniting and union was becoming organisation--and neither geographical remoteness, nor unwieldiness of numbers, nor local interests and differences, were untractable obstacles to that spirit of fusion which was at once the ambition of the few and the instinct of the many; and cities, even where most powerful, had become the centres of the attracting and joining forces, knots in the political network--while this was going on more or less happily throughout the rest of Europe, in Italy the ancient classic idea lingered in its simplicity, its narrowness and jealousy, wherever there was any political activity. The history of Southern Italy indeed is mainly a foreign one, the history of modern Rome merges in that of the Papacy; but Northern Italy has a history of its own, and that is a history of separate and independent cities--points of reciprocal and indestructible repulsion, and within, theatres of action where the blind tendencies and traditions of classes and parties weighed little on the freedom of individual character, and citizens could watch and measure and study one another with the minuteness of private life.
