There is wonderful relation and correspondence in this universal government of the works of nature, which very well makes it appear that it is neither accidental nor carried on by divers masters. The diseases and conditions of our bodies are, in like manner, manifest in states and governments; kingdoms and republics are founded, flourish, and decay with age as we do. We are subject to a repletion of humours, useless and dangerous: whether of those that are good (for even those the physicians are afraid of; and seeing we have nothing in us that is stable, they say that a too brisk and vigorous perfection of health must be abated by art, lest our nature, unable to rest in any certain condition, and not having whither to rise to mend itself, make too sudden and too disorderly a retreat; and therefore prescribe wrestlers to purge and bleed, to qualify that superabundant health), or else a repletion of evil humours, which is the ordinary cause of sickness. States are very often sick of the like repletion, and various sorts of purgations have commonly been applied. Some times a great multitude of families are turned out to clear the country, who seek out new abodes elsewhere and encroach upon others. After this manner our ancient Franks came from the remotest part of Germany to seize upon Gaul, and to drive thence the first inhabitants; so was that infinite deluge of men made up who came into Italy under the conduct of Brennus and others; so the Goths and Vandals, and also the people who now possess Greece, left their native country to go settle elsewhere, where they might have more room; and there are scarce two or three little corners in the world that have not felt the effect of such removals. The Romans by this means erected their colonies; for, perceiving their city to grow immeasurably populous, they eased it of the most unnecessary people, and sent them to inhabit and cultivate the lands conquered by them; sometimes also they purposely maintained wars with some of their enemies, not only to keep their own men in action, for fear lest idleness, the mother of corruption, should bring upon them some worse inconvenience: "Et patimur longae pacis mala; saevior armis Luxuria incumbit." ["And we suffer the ills of a long peace; luxury is more pernicious than war."--Juvenal, vi. 291.] but also to serve for a blood-letting to their Republic, and a little to evaporate the too vehement heat of their youth, to prune and clear the branches from the stock too luxuriant in wood; and to this end it was that they maintained so long a war with Carthage.
