systematically discouraged; judicial bribery was considered a crime of peculiar infamy; and the practice of holding the magistrate responsible for the maintenance of peace in his district was a most efficient check upon the violence and depredations of professional malefactors. In the statutes relating to the detection and punishment of heresy, the character of Frederick appears to singular and manifest disadvantage. His long wars with the Pope, his close intimacy with infidels, his oppression of ecclesiastics, the repeated acts of sacrilege of which he was guilty, the blasphemous speeches constantly upon his tongue, the profane and mysterious studies in which he delighted, his employment of and confidence in wizards and astrologers, demonstrate beyond contradiction the weakness of his faith or the profoundness of his hypocrisy. But the latitude of opinion and conduct which he allowed himself was in an inverse ratio to that which he vouchsafed to others. No familiar of the Inquisition ever pursued heretics with greater zeal or pertinacity than the famous monarch whose name is constantly associated with all that is liberal, enlightened, and profitable in the annals of human progress, an inconsistency all the more glaring in a prince whose favorite sentiment was, “The glory of a ruler is the safe and comfortable condition of the subject.” History has never been able to advance a satisfactory or even a plausible explanation of this anomaly; its cause, at this distance of time, must remain forever unknown, and may be ascribed, for want of a better solution, to the innate perversity of the human mind, which often by a single glaring defect obscures the brilliant lustre of a character eminently conspicuous for every princely quality, for every generous impulse, and for every literary and artistic excellence. His commercial regulations were among the principal sources of Frederick’s power and greatness. His genius perceived at a glance the vast advantages which must result from an interchange of commodities with maritime nations; and, in the application of this principle, every facility was afforded those bold spirits whose energy the expectation of gain or the love of adventure directed into the channels of trade. Treaties more liberal in their provisions and more profitable in their effects than any which had heretofore been adopted by the powers of the Mediterranean were concluded with the greatest mercantile communities of Europe,--Constantinople, Venice, Genoa,--as well as with Damascus and Alexandria and the Moorish principalities of Africa and Spain.
