tion, but on argument, have retarded the progress of rea knowledge. The metaphysics of infinite, or finite, spirit have too often been enlisted in the service of superstition. But the human faculties are fortified by the art and practice of dialectics; the ten predicaments of Aristotle collect and methodize our ideas, and his syllogism is the keenest weapon of dispute. It was dexterously wielded in the schools of the Saracens, but as it is more effectual for the detection of error han for the investigation of truth, it is not surprising that new generations of masters and disciples should still revolve in the same circle of logical argument. The mathematics are distinguished by a peculiar privilege, that, in the course of ages, they may always advance, and can never recede. But the ancient geometry, if I am not misinformed, was resumed in the same state by the Italians of the fifteenth century; and whatever may be the origin of the name, the science of ge bra is ascribed to the Grecian Diophantus by the modest testimony of the Arabs themselves. They cultivated with more success the sublime science of astronomy, which elevates the mind of man to disdain his diminutive planet and momentary existence. The costly instruments of observation were supplied by the caliph Almamon, and the land of the Chaldæans still afforded the same spacious level, the same unclouded horizon. In the plains of Sinaar, and a second time in those of Cufa, his mathematicians accurately measured a degree of the great circle of the earth, and determined at twenty-four thousand miles the entire circumference of our globe.

the reign of the Abbassides to that of the grandchildren of Tamerlane, the stars, without the aid of glasses, were diligently observed; and the astronomical tables of Bagdad, Spain, and Samarcand, correct some minute errors, without daring to renounce the hypothesis of Ptolemy, without advancing a step towards the discovery of the solar system. In the Eastern courts, the truths of science could be recommended only by ignorance and folly, and the astronomer would have been disregarded, had he not debased his wisdom er honesty by the vain predictions of astrology." But in the science of medicine, the Arabians have been deservedly applauded. The names of Mesua and Geber, of Razis and Avicenna, are ranked with the Grecian masters; in the city of Bagdad, eight hundred and sixty physicians were licensed to exercise their lucrative profession: in Spain, the life of the Catholic princes was intrusted to the skill of the Saracens, and the school of Salerno, their legitimate offspring, revived in Italy and Europe the precepts of the healing art. The success of each professor must have been influenced by personal and accidental causes; but we may form a less fanciful estimate of their general knowledge of anatomy," botany, and chemistry," the threefold basis of their theory and

practice. A superstitious reverence for the dead confined both the Greeks and the Arabians to the dissection of apes and quadrupeds; the more solid and visible parts were known in the time of Galen, and the finer scrutiny of the human frame was reserved for the microscope and the injections of modern artists. Botany is an active science, and the discoveries of the torrid zone might enrich the herbal of Dioscorides with two thousand plants. Some traditionary knowledge might be se creted in the temples and monasteries of Egypt; much useful experience had been acquired in the practice of arts and manufactures; but the science of chemistry owes its origin and improvement to the industry of the Saracens. They first invented and named the alembic for the purposes of distillation, analyzed the substances of the three kingdoms of nature, tried the distinction and affinities of alcalis and acids, and converted the poisonous minerals into soft and salutary medicines. But the most eager search of Arabian chemistry was the transmutation of metals, and the elixir of immortal health: the reason and the fortunes of thousands were evaporated in the crucibles of alchemy, and the consummation of the great work was promoted by the worthy aid of mystery, fable, and superstition.

But the Moslems deprived themselves of the principal benefits of a familiar intercourse with Greece and Rome, the. knowledge of antiquity, the purity of taste, and the freedom of thought. Confident in the riches of their native tongue, the Arabians disdained the study of any foreign idiom. The Greek interpreters were chosen among their Christian subjects; they formed their translations, sometimes on the origi

the original merit of the Arabians. Yet he quotes the modest confes sion of the famous Geber of the ixth century, (D'Herbelot, p. 387,) that he had drawn most of his science, perhaps the transmutation of metals, from the ancient sages. Whatever might be the origin or extent of their knowledge, the arts of chemistry and alchemy appear to have been known in Egypt at least three hundred years before Mahomet, (Wotton's Reflections, p. 121–133. Pauw, Recherches sur les Egypt iens et les Chinois, tom. i. p. 376-429.)*

nal text, more frequently perhaps on a Syriac version and in the crowd of astronomers and physicians, there is no example of a poet, an orator, or even an historian, being taught to speak the language of the Saracens. The mythology of Homer would have provoked the abhorrence of those stern fanatics they possessed in lazy ignorance the colonies of the Macedonians, and the provinces of Carthage and Rome: the heroes of Plutarch and Livy were buried in oblivion; and the history of the world before Mahomet was reduced to a short legend of the patriarchs, the prophets, and the Persian kings. Our education in the Greek and Latin schools may have fixed in our minds a standard of exclusive taste; and I am not forward to condemn the literature and judgment of nations, of whose language I am ignorant. Yet I know that the classics have much to teach, and I believe that the Orientals have much to learn; the temperate dignity of style, the graceful proportions of art, the forms of visible and intellectual beauty, the just delineation of character and passion, the rhetoric of narrative and argument, the regular fabric of epic and dramatic poetry." The influence of truth and reason is of a less ambiguous complexion. The philosophers of Athens and Rome enjoyed the blessings, and asserted the rights, of civil and religious freedom. Their moral and political writings might have gradually unlocked the fetters of Eastern despotism, diffused a liberal spirit of inquiry and toleration, and encouraged the Arabian sages to suspect that their caliph was a tyrant, and their prophet an impostor. impostor." The instinct of superstitition was alarmed by the introduction even of the abstract

70 Abulpharagius (Dynast. p. 26, 148) mentions a Syriac version of Homer's two poems, by Theophilus, a Christian Maronite of Mount Libanus, who professed astronomy at Roha or Edessa towards the end of the viiith century. His work would be a literary curiosity. I have read somewhere, but I do not believe, that Piutarch's Lives were translated into Turkish for the use of Mahomet the Second.

"I have perused, with much pleasure, Sir William Jones's Latin Commentary on Asiatic Poetry, (London, 1774, in octavo,) which was composed in the youth of that wonderful linguist. At present, in the maturity of his taste and judgment, he would perhaps abate of the fervent, and even partial, praise which he has bestowed on the Orientals.

sciences; and the more rigid doctors of the law condemned the rash and pernicious curiosity of Almamon." To the thirst of martyrdom, the vision of paradise, and the belief of predestination, we must ascribe the invincible enthusiasm of the prince and people. And the sword of the Saracens became less formidable when their youth was drawn away from the camp to the college, when the armies of the faithful presumed to read and to reflect. Yet the foolish vanity of the Greeks was jealous of their studies, and reluctantly imparted the sacred fire to the Barbarians of the East."

In the bloody conflict of the Ommiades and Abbassides, the Greeks had stolen the opportunity of avenging their wrongs and enlarging their limits. But a severe retribution was exacted by Mohadi, the third caliph of the new dynasty, who seized, in his turn, the favorable opportunity, while a woman and a child, Irene and Constantine, were seated on the Byzantine throne. An army of ninety-five thousand Persians and Arabs was sent from the Tigris to the Thracian Bosphorus, under the command of Harun," or Aaron, the second son of the commander of the faithful. His encampment on the opposite heights of Chrysopolis, or Scutari, informed Irene, in her palace of Constantinople, of the loss of her troops and provinces. With the consent or connivance of their sovereign, her ministers subscribed an ignominious peace; and the exchange of some royal gifts could not disguise the annual tribute of seventy thousand dinars of gold, which was imposed on the Roman empire. The Saracens had too rashly advanced into the midst of a distant and hostile land: their retreat was solicited by the promise of faithful guides and plentiful markets; and not a Greek had courage to whisper, that their weary forces might be surrounded and destroyed in their necessary passage between a slippery
