In order that the reader may thoroughly understand and properly appreciate the moral and intellectual supremacy of the Spanish Arabs and their prodigious advance in the domain of science and the arts, I have thought it advisable, by way of contrast, to present to him a short and superficial sketch of the religious, political, and domestic conditions which prevailed in the society of contemporaneous Europe. The extent of this vast and comprehensive subject--one which has exhausted the erudition of many great historians, whose works of themselves would constitute a considerable library--must, therefore, excuse the incomplete and cursory character of this chapter; while its importance as a standard of comparison will account for an apparent deviation from the general plan embraced by these volumes. The elegant luxury and refined civilization of the Romans had disappeared amidst the universal anarchy which followed the dissolution of their empire. The boundaries of great states and kingdoms had been obliterated. Provinces once famed for their fertility were now the haunts of prowling beasts and truculent barbarians. The despotic but generally salutary government of the Cæsars had everywhere, save in the immediate vicinity of Byzantium, been replaced by the capricious and irregular jurisdiction of petty chieftains, whose violent passions were restrained only by their weakness, and of marauding princes, ambitious to destroy every vestige of that architectural magnificence and mental culture whose monuments they despised, and whose example they had neither the desire nor the capacity to emulate. Instead of a smiling landscape, everywhere exhibiting the traces of agricultural skill and laborious and patient industry, a prospect of universal desolation met the eye of the anxious and hurrying wayfarer. Moss-grown heaps of rubbish alone marked the site of many a once flourishing and opulent city. The towering aqueducts,--those engineering marvels of the ancient world,--whose majestic ruins still excite the admiration of all mankind, were broken and fallen into decay. The peerless temples and altars of the gods had been desecrated by the hands of sacrilegious Goth, Hun, and Lombard. Bands of brigands, insensible to pity, swarmed upon the highways. In the cities the equitable decisions of the prætor had been supplanted by the extortions of ecclesiastical fraud and barbarian insolence. The vices prevalent during the most abandoned period of Roman licentiousness had survived, and had been aggravated by the unfeeling cruelty of the conquerors. No scruples of humanity or delicacy suggested the concealment of the most revolting orgies. The streets of the Eternal City exhibited enormities whose very mention the rules of modern propriety do not tolerate. Banquets where the brutal propensities of the turbulent and uncouth guests were indulged to the utmost constantly afforded provocation for bloodshed and murder.
