The history of Italian freedom, from the Middle Ages to the new series of foreign invasions, dating from the descent of Charles VIII. in 1494, mainly consists of the history of our communes. But this history is as yet unwritten, and, worse still, can never be written until the material required for the task shall have been brought to light, sifted, and illustrated. What were the most ancient political statutes, what those of the guilds of art and commerce, what the penal and civil laws, the individual conditions, revenue, expenditure, trade, and industry of those republics? To all these questions we can give but imperfect replies at the best, and some are left altogether unsolved. Yet until all are decided the civil history of our communes remains involved in obscurity. Through Machiavelli and Giannone Italy gave the world the first essays in constitutional history, and by Muratori's gigantic labours inaugurated the great school of learning that is the only settled basis of modern and, more especially, of constitutional history. But we soon allowed the sceptre we had won to be snatched from our grasp. It is true that we have never experienced any dearth of great scholars or historians, but the complete national history of a people is a task exceeding the powers of one or of several individuals. Such history must be produced, as it were, by the nation itself. Only the combined efforts of many scholars and of many generations can succeed in co-ordinating and investigating the vast mass of material that has to be ransacked in order to trace through the vicissitudes of numerous municipalities, all differing from, and at war with one another, the history of the Italian people. It has been long the custom with us for every one to work independently: hence we lack the spirit of agreement and co-operation required to enable individual efforts to carry forward the work of the whole country at the same pace. Certainly, however, I must not forget to note the example of our various national historical societies, subsidised by the Government, and composed of most learned and deserving men. But these associations and commissions have as yet no general nor united plan of work; and, in fact, some of their members are apt to devote their energies to labours which, however important, are disconnected from the main object. Thus there will be much delay before our learned men complete the investigation of any one period of our history. Yet the rules which should be followed are not far to seek, since Italians were the first to discover them, and we still bear them in mind. Nor has the issue of highly important collections of documents been relegated exclusively to our societies and commissions. None can have forgotten the untiring labours of the worthy Vieusseux and his friends in their management of the "Archivio Storico Italiano"! To show what excellent results may be achieved by the publication of a single series of State papers, it is sufficient to
