Born under a southern sky, accustomed from childhood to daily intercourse with the most intellectual society of the age, Frederick II. retained to the last a decided predilection for Sicily, the land of his birth. The classic memories and romantic history of that famous island exerted over his active mind a most potent and lasting influence. He had no sympathy with, and less inclination for, the rude and barbarous customs, the coarse festivities, the ferocity, drunkenness, and bestiality of that country which was the original seat of his royal House, the realm whence he derived the proudest and most grandiloquent of his numerous titles. Educated by two Moorish preceptors, under the superintendence of a cardinal,--a curious circumstance which indicates that infidel learning had not yet entirely succumbed to ecclesiastical prejudice,--he in time became proficient in all the arts and accomplishments possessed by that remarkable people whose erudition and industry were admired and feared by the dominant race whose members the fortune of arms had made the depositaries of power and the interpreters of orthodoxy. This early, intimate, and constant association with Mohammedans and Greeks, in each of whose systems of government the temporal and spiritual functions were vested in one individual, undoubtedly suggested to the mind of the Emperor the stupendous project of merging the Papal office in the imperial dignity,--a combination of two despotisms under a single head, whose powers, of uncertain and indefinable extent, could not be questioned without incurring the penalties of both treason and sacrilege, and whose jurisdiction would eventually embrace the habitable world. The political and judicial systems instituted and perfected by Frederick II., remarkable in themselves, become almost marvellous when considered in relation to the era of their establishment, the difficulties encountered in their application, and the antagonism of the privileged classes whose designs they interfered with and whose abuses they were intended to correct and restrain. Two questions of paramount importance engaged the attention of this enlightened prince, questions containing in themselves the solution of every administrative and every social problem,--the promulgation of law and implicit obedience to its mandates, and the adoption of measures which might secure the greatest attainable happiness of the people. To the accomplishment of these noble and praiseworthy ends the talents and energy of the great ruler were constantly devoted,--in hours of triumph and in hours of humiliation; when engrossed with the cares of a vast and seditious empire; in the deserts of Syria; in the very face of death; in the bitterness of spirit induced by shattered dreams of long-nourished ambition.
