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.In the second case, namely of a city being founded by strangers, the settlers are either wholly independent, or they are controlled by others, as where colonies are sent forth either by a prince or by a republic, to relieve their countries of an excessive population, or to defend newly acquired territories which it is sought to secure at small cost. Of this sort many cities were settled by the Romans, and in all parts of their dominions. It may also happen that such cities are founded by a prince merely to add to his renown, without any intention on his part to dwell there, as Alexandria was built by Alexander the Great. Cities like these, not having had their beginning in freedom, seldom make such progress as to rank among the chief towns of kingdoms.The city of Florence belongs to that class of towns which has not been independent from the first; for whether we ascribe its origin to the soldiers of Sylla, or, as some have conjectured, to the mountaineers of Fiesole (who, emboldened by the long peace which prevailed throughout the world during the reign of Octavianus, came down to occupy the plain on the banks of the Arno), in either case, it was founded under the auspices of Rome nor could, at first, make other progress than was permitted by the grace of the sovereign State.The origin of cities may be said to be independent when a people, either by themselves or under some prince, are constrained by famine, pestilence, or war to leave their native land and seek a new habitation. Settlers of this sort either establish themselves in cities which they find ready to their hand in the countries of which they take possession, as did Moses; or they build new ones, as did Æneas. It is in this last case that the merits of a founder and the good fortune of the city founded are best seen; and this good fortune will be more or less remarkable according to the greater or less capacity of him who gives the city its beginning.
