The two Antonines fix an era in the imperial history; for they were both eminent models of wise and good rulers; and some would say, that they fixed a crisis; for with their successor commenced, in the popular belief, the decline of the empire. That at least is the doctrine of Gibbon; but perhaps it would not be found altogether able to sustain itself against a closer and philosophic examination of the true elements involved in the idea of declension as applied to political bodies. Be that as it may, however, and waiving any interest which might happen to invest the Antonines as the last princes who kept up the empire to its original level, both of them had enough of merit to challenge a separate notice in their personal characters, and apart from the accidents of their position. The elder of the two, who is usually distinguished by the title of _Pius_, is thus described by one of his biographers:--"He was externally of remarkable beauty; eminent for his moral character, full of benign dispositions, noble, with a countenance of a most gentle expression, intellectually of singular endowments, possessing an elegant style of eloquence, distinguished for his literature, generally temperate, an earnest lover of agricultural pursuits, mild in his deportment, bountiful in the use of his own, but a stern respecter of the rights of others; and, finally, he was all this without ostentation, and with a constant regard to the proportions of cases, and to the demands of time and place." His bounty displayed itself in a way, which may be worth mentioning, as at once illustrating the age, and the prudence with which he controlled the most generous of his impulses:--"_Finus trientarium_," says the historian, "_hoc est minimis usuris exercuit, ut patrimonio suo plurimos adjuvaret_." The meaning of which is this:--in Rome, the customary interest for money was what was called _centesimæ usuræ_; that is, the hundredth part, or one per cent. But, as this expressed not the annual, but the _monthly_ interest, the true rate was, in fact, twelve per cent.; and that is the meaning of _centesimæ usuræ_. Nor could money be obtained any where on better terms than these; and, moreover, this one per cent, was exacted rigorously as the monthly day came round, no arrears being suffered to lie over. Under these circumstances, it was a prodigious service to lend money at a diminished rate, and one which furnished many men with the means of saving themselves from ruin. Pius then, by way of extending his aid as far as possible, reduced the monthly rate of his loans to one-third per cent., which made the annual interest the very moderate one of four per cent. The channels, which public spirit had as yet opened to the beneficence of the opulent, were few indeed: charity and munificence languished, or they were abused, or they were inefficiently directed, simply through defects in the structure of society. Social organization, for its large development,
