After this narrative of the expeditions of the Latins to Palestine and Constantinople, I cannot dismiss the subject without revolving the general consequences on the countries that were the scene, and on the nations that were the actors, of these memorable crusades. Ref. 084 As soon as the arms of the Franks were withdrawn, the impression, though not the memory, was erased in the Mahometan realms of Egypt and Syria. The faithful disciples of the prophet were never tempted by a profane desire to study the laws or language of the idolaters; nor did the simplicity of their primitive manners receive the slightest alteration from their intercourse in peace and war with the unknown strangers of the West. The Greeks, who thought themselves proud, but who were only vain, shewed a disposition somewhat less inflexible. In the efforts for the recovery of their empire they emulated the valour, discipline, and tactics of their antagonists. The modern literature of the West they might justly despise; but its free spirit would instruct them in the rights of man; and some institutions of public and private life were adopted from the French. The correspondence of Constantinople and Italy diffused the knowledge of the Latin tongue; and several of the fathers and classics were at length honoured with a Greek version. Ref. 085 But the national and religious prejudices of the Orientals were inflamed by persecution; and the reign of the Latins confirmed the separation of the two churches.
If we compare, at the era of the crusades, the Latins of Europe with the Greeks and Arabians, their respective degrees of knowledge, industry, and art, our rude ancestors must be content with the third rank in the scale of nations. Their successive improvement and present superiority may be ascribed to a peculiar energy of character, to an active and imitative spirit, unknown to their more polished rivals, who at that time were in a stationary or retrograde state. With such a disposition, the Latins should have derived the most early and essential benefits from a series of events which opened to their eyes the prospect of the world, and introduced them to a long and frequent intercourse with the more cultivated regions of the East. The first and most obvious progress was in trade and manufactures, in the arts which are strongly prompted by the thirst of wealth, the calls of necessity, and the gratification of the sense or vanity. Among the crowd of unthinking fanatics, a captive or a pilgrim might sometimes observe the superior refinements of Cairo and Constantinople: the first importer of windmills Ref. 086 was the benefactor of nations; and, if such blessings are enjoyed without any grateful remembrance, history has condescended to notice the more apparent luxuries of silk and sugar, which were transported into Italy from Greece and Egypt. But the intellectual wants of the Latins were more slowly felt and supplied; the ardour of studious curiosity was awakened in Europe by different causes and more recent events; and, in the age of the crusades, they viewed with careless indifference the literature of the Greeks and Arabians. Some rudiments of mathematical and medicinal knowledge might be imparted in practice and in figures; necessity might produce some interpreters for the grosser business of merchants and soldiers; but the commerce of the Orientals had not diffused the study and knowledge of their languages in the schools of Europe. Ref. 087 If a similar principle of religion repulsed the idiom of the Koran, it should have excited their patience and curiosity to understand the original text of the gospel; and the same grammar would have unfolded the sense of Plato and the beauties of Homer. Yet in a reign of sixty years, the Latins of Constantinople disdained the speech and learning of their subjects; and the manuscripts were the only treasures which the natives might enjoy without rapine or envy. Aristotle was indeed the oracle of the Western universities; but it was a Barbarous Aristotle; and, instead of ascending to the fountain-head, his Latin votaries humbly accepted a corrupt and remote version from the Jews and Moors of Andalusia. The principle of the crusades was a savage fanaticism; and the most important effects were analogous to the cause. Each pilgrim was ambitious to return with his sacred spoils, the relics of Greece and Palestine; Ref. 088 and each relic was preceded and followed by a train of miracles and visions. The belief of the Catholics was corrupted by new legends, their practice by new superstitions; and the establishment of the inquisition, the mendicant orders of monks and friars, the last abuse of indulgences, and the final progress of idolatry flowed from the baleful fountain of the holy war. The active spirit of the Latins preyed on the vitals of their reason and religion; and, if the ninth and tenth centuries were the times of darkness, the thirteenth and fourteenth were the age of absurdity and fable.
In the profession of Christianity, in the cultivation of a fertile land, the Northern conquerors of the Roman empire insensibly mingled with the provincials and rekindled the embers of the arts of antiquity. Their settlements about the age of Charlemagne had acquired some degree of order and stability, when they were overwhelmed by new swarms of invaders, the Normans, Saracens, Ref. 089 and Hungarians, who replunged the Western countries of Europe into their former state of anarchy and barbarism. About the eleventh century, the second tempest had subsided by the expulsion or conversion of the enemies of Christendom: the tide of civilisation, which had so long ebbed, began to flow with a steady and accelerated course; and a fairer prospect was opened to the hopes and efforts of the rising generations. Great was the success, and rapid the progress, during the two hundred years of the crusades; and some philosophers have applauded the propitious influence of these holy wars, which appear to me to have checked, rather than forwarded, the maturity of Europe. Ref. 090 The lives and labours of millions, which were buried in the East, would have been more profitably employed in the improvement of their native country: the accumulated stock of industry and wealth would have overflowed in navigation and trade; and the Latins would have been enriched and enlightened by a pure and friendly correspondence with the climates of the East. In one respect I can
