The encroachment of large proprietors upon small proprietors, by the aid of usury, farm-rent, and profits of all sorts, was common throughout the empire. The most honest citizens invested their money at high rates of interest. [53] Cato, Cicero, Brutus, all the stoics so noted for their frugality, _viri frugi_,--Seneca, the teacher of virtue,--levied enormous taxes in the provinces, under the name of usury; and it is something remarkable, that the last defenders of the republic, the proud Pompeys, were all usurious aristocrats, and oppressors of the poor. But the battle of Pharsalus, having killed men only, without touching institutions, the encroachments of the large domains became every day more active. Ever since the birth of Christianity, the Fathers have opposed this invasion with all their might. Their writings are filled with burning curses upon this crime of usury, of which Christians are not always innocent. St. Cyprian complains of certain bishops of his time, who, absorbed in disgraceful stock-jobbing operations, abandoned their churches, and went about the provinces appropriating lands by artifice and fraud, while lending money and piling up interests upon interests. [54] Why, in the midst of this passion for accumulation, did not the possession of the public land, like private property, become concentrated in a few hands? By law, the domain of the State was inalienable, and consequently possession was always revocable; but the edict of the praetor continued it indefinitely, so that finally the possessions of the patricians were transformed into absolute property, though the name, possessions, was still applied to them. This conversion, instigated by senatorial avarice; owed its accomplishment to the most deplorable and indiscreet policy. If, in the time of Tiberius Gracchus, who wished to limit each citizen's possession of the ager publicus to five hundred acres, the amount of this possession had been fixed at as much as one family could cultivate, and granted on the express condition that the possessor should cultivate it himself, and should lease it to no one, the empire never would have been desolated by large estates; and possession, instead of increasing property, would have absorbed it. On what, then, depended the establishment and maintenance of equality in conditions and fortunes? On a more equitable division of the ager publicus, a wiser distribution of the right of possession.
