who, to relieve their states from an excessive population, or to defend a newly acquired territory which they wish to preserve without expense, send colonies there. The Romans founded many cities in this way within their empire. Sometimes cities are built by a prince, not for the purpose of living there, but merely as monuments to his glory; such was Alexandria, built by Alexander the Great. But as all these cities are at their very origin deprived of liberty, they rarely succeed in making great progress, or in being counted amongst the great powers. Such was the origin of Florence; for it was built either by the soldiers of Sylla, or perhaps by the inhabitants of Mount Fiesole, who, trusting to the long peace that prevailed in the reign of Octavian, were attracted to the plains along the Arno. Florence, thus built under the Roman Empire, could in the beginning have no growth except what depended on the will of its master.
The founders of cities are independent when they are people who, under the leadership of some prince, or by themselves, have been obliged to fly from pestilence, war, or famine, that was desolating their native country, and are seeking a new home. These either inhabit the cities of the country of which they take possession, as Moses did; or they build new ones, as was done by Æneas. In such case we are able to appreciate the talents of the founder and the success of his work, which is more or less remarkable according as he, in founding the city, displays more or less wisdom and skill. Both the one and the other are recognized by the selection of the place where he has located the city, and by the nature of the laws which he establishes in it. And as men work either from necessity or from choice, and as it has been observed that virtue has more sway where labor is the result of necessity rather than of choice, it is a matter of consideration whether it might not be better to select for the establishment of a city a sterile region, where the people, compelled by necessity to be industrious, and therefore less given to idleness, would be more united, and less exposed by the poverty of the country to occasions for discord; as was the case with Ragusa, and several other cities that were built upon an ungrateful soil. Such a selection of site would doubtless be more useful and wise if men were content with what they possess, and did not desire to exercise command over others.
