What have been generally the principles of all Cities, and particularly of Rome
THose who shall read the Original of the City of Rome, by what Legislators advanced and by what Government ordered, will not wonder it shall remain firm and entire for so many ages, afterwards so vast an Empire spring out of it as that Common∣wealth arrived to. Being to discourse first of its Original, it is convenient to premise, that all Cities are built either by natives born in the Country where they were erected, or by stran∣gers. The first happens when, to the Inhabitants dispersed in many and little parties, it appears their habitation is insecure, not being able apart (by reason of their distance, or smalness of their numbers) to resist an invasion, (if any Enemy should fall upon them) or to unite suddenly for their defence, without leaving their Houses and Families exposed, which by consequence would be certain prey to the enemy. Whereupon, to evade those dangers, moved either by their own impulse, or the suggestions of some person among them of more than ordinary authority, they oblige themselves to live together in some place to be chosen by them for convenience of provision, and easiness of defence. Of this sort, among many others, Athens and Venice were two: the first that built under the autho∣rity of Theseus, upon occasion of the like distance and dispersion of the natives. The other (there being many people driven together into certain little Islands in that point of the Adriatick Sea, to avoid the War which every day, by the access and irruption of new Armies of Barbarians after the declension of the Roman Empire grew intolerable in Italy) began by degrees among themselves, without the assistance or encouragement of any Prince, to treat and submit to such Laws as appeared most likely to preserve them: and it succeeded to their desire by the long respite and tranquillity their situation afforded them; that Sea having no passage at that end, and the Barbarians no ships to disturb them; so that the least beginning imaginable was sufficient to exalt them to their present authority and gran∣deur.
The second case, when a City is raised by strangers, it is done by people that are free, or depending (as Colonies) or else by some Prince or Republick to ease and disburthen themselves of their exuberance, or to defend some Territory, which being newly acquir'd, they desire with more safety and less expence to maintain (of which sort several were by the people of Rome all over their Empire) otherwise they are sometimes erected by some Prince, not for his residence so much as for his glory and renown (as Alexandria by Alexander the great). But these Cities not being free in their Original, do seldom arise to any extraordinary height more than to be reckoned the heads or chief of some Kingdom. Of this sort was Florence, for (whether built by the Souldiers of Silla, or perchance by the
