The ancient republics derived their chief or only security from the numbers of their citizens. The Trachinians having lost great numbers of their people, the remainder, instead of enriching themselves by the inheritance of their fellow-citizens, applied to Sparta, their metropolis, for a new stock of inhabitants. The Spartans immediately collected ten thousand men, among whom the old citizens divided the lands of which the former proprietors had perished.
After Timoleon had banished Dionysius from Syracuse {p127} and had settled the affairs of Sicily, finding the cities of Syracuse and Sellinuntium extremely depopulated by tyranny, war, and faction, he invited over from Greece some new inhabitants to repeople them. Immediately forty thousand men (Plutarch says sixty thousand) offered themselves, and he distributed so many lots of land among them, to the great satisfaction of the ancient inhabitants; a proof at once of the maxims of ancient policy, which affected populousness more than riches, and of the good effects of these maxims in the extreme populousness of that small country Greece, which could at once supply so large a colony. The case was not much different with the Romans in early times. “He is a pernicious citizen,” said M. Curius, “who cannot be contented with seven acres.”56 Such ideas of equality could not fail of producing great numbers of people.
We must now consider what disadvantages the ancients lay under with regard to populousness, and what checks they received from their political maxims and institutions. There are commonly compensations in every human condition, and though these compensations be not always perfectly equal, yet they serve, at least, to restrain the prevailing principle. To compare them and estimate their influence is indeed very difficult, even where they take place in the same age, and in neighbouring countries; but where several ages have intervened, and only scattered lights are afforded us by ancient authors, what can we do but amuse ourselves by talking, pro and con, on an interesting subject, and thereby correcting all hasty and violent determinations? {p128}
