Desiring to rescue men from this error, I have thought fit to note down with respect to all those books of Titus Livius which have escaped the malignity of Time, whatever seems to me essential to a right understanding of ancient and modern affairs; so that any who shall read these remarks of mine, may reap from them that profit for the sake of which a knowledge of History is to be sought. And although the task be arduous, still, with the help of those at whose instance I assumed the burthen, I hope to carry it forward so far, that another shall have no long way to go to bring it to its destination. CHAPTER I.—_Of the Beginnings of Cities in general, and in particular of that of Rome._ No one who reads how the city of Rome had its beginning, who were its founders, and what its ordinances and laws, will marvel that so much excellence was maintained in it through many ages, or that it grew afterwards to be so great an Empire. And, first, as touching its origin, I say, that all cities have been founded either by the people of the country in which they stand, or by strangers. Cities have their origins in the former of these two ways when the inhabitants of a country find that they cannot live securely if they live dispersed in many and small societies, each of them unable, whether from its situation or its slender numbers, to stand alone against the attacks of its enemies; on whose approach there is no time left to unite for defence without abandoning many strongholds, and thus becoming an easy prey to the invader. To escape which dangers, whether of their own motion or at the instance of some of greater authority among them, they restrict themselves to dwell together in certain places, which they think will be more convenient to live in and easier to defend. Among many cities taking their origin in this way were Athens and Venice; the former of which, for reasons like those just now mentioned, was built by a scattered population under the direction of Theseus. To escape the wars which, on the decay of the Roman Empire daily renewed in Italy by the arrival of fresh hordes of Barbarians, numerous refugees, sheltering in certain little islands in a corner of the Adriatic Sea, gave beginning to Venice; where, without any recognized leader to direct them, they agreed to live together under such laws as they thought best suited to maintain them. And by reason of the prolonged tranquility which their position secured, they being protected by the narrow sea and by the circumstance that the tribes who then harassed Italy had no ships wherewith to molest them, they were able from very small beginnings to attain to that greatness they now enjoy.
