THE RESTORATION OF SCIENCE IN THE SOUTH.
By the influence of the Nestorians and Jews, the Arabians are turned to the cultivation of Science.—They modify their views as to the destiny of man, and obtain true conceptions respecting the structure of the world.—They ascertain the size of the earth, and determine its shape. —Their khalifs collect great libraries, patronize every department of science and literature, establish astronomical observatories.—They develop the mathematical sciences, invent algebra, and improve geometry and trigonometry.—They collect and translate the old Greek mathematical and astronomical works, and adopt the inductive method of Aristotle.—They establish many colleges, and, with the aid of the Nestorians, organize a public-school system.—They introduce the Arabic numerals and arithmetic, and catalogue and give names to the stars.—They lay the foundation of modern astronomy, chemistry, and physics, and introduce great improvements in agriculture and manufactures.
"IN the course of my long life," said the Khalif Ali, "I have often observed that men are more like the times they live in than they are like their fathers." This profoundly philosophical remark of the son-in-law of Mohammed is strictly true; for, though the personal, the bodily lineaments of a man may indicate his parentage, the constitution of his mind, and therefore the direction of his thoughts, is determined by the environment in which he lives.
When Amrou, the lieutenant of the Khalif Omar, conquered Egypt, and annexed it to the Saracenic Empire,
Although the fact has been denied, there can be little doubt that Omar gave this order. The khalif was an illiterate man; his environment was an environment of fanaticism and ignorance. Omar's act was an illustration of Ali's remark.
But it must not be supposed that the books which John the Labor-lover coveted were those which constituted the great library of the Ptolemies, and that of Eumenes, King of Pergamus. Nearly a thousand years had elapsed since Philadelphus began his collection. Julius Cæsar had burnt more than half; the Patriarchs of Alexandria had not only permitted but superintended the dispersion of almost all the rest. Orosius expressly states that he saw the empty cases or shelves of the library twenty years after Theophilus, the uncle of St. Cyril, had procured from the Emperor Theodosius a rescript for its destruction. Even had this once noble collection never endured such acts of violence, the mere wear and tear, and perhaps, I may add, the pilfering of a thousand years, would have diminished it sadly. Though John, as the surname he received indicates, might rejoice in
There can, then, be no more doubt that Omar did order the destruction of this library, under an impression of its uselessness or its irreligious tendency, than that the Crusaders burnt the library of Tripoli, fancifully said to have consisted of three million volumes. The first apartment entered being found to contain nothing but the Koran, all the other books were supposed to be the works of the Arabian impostor, and were consequently committed to the flames. In both cases the story contains some truth and much exaggeration. Bigotry, however, has often distinguished itself by such exploits. The Spaniards burnt in Mexico vast piles of American picture-writings, an irretrievable loss; and Cardinal Ximenes delivered to the flames, in the squares of Granada, eighty thousand Arabic manuscripts, many of them translations of classical authors.
We have seen how engineering talent, stimulated by Alexander's Persian campaign, led to a wonderful development of pure science under the Ptolemies; a similar
The friendship contracted by Amrou, the conqueror of Egypt, with John the Grammarian, indicates how much the Arabian mind was predisposed to liberal ideas. Its step from the idolatry of the Caaba to the monotheism of Mohammed prepared it to expatiate in the wide and pleasing fields of literature and philosophy. There were two influences to which it was continually exposed. They conspired in determining its path. These were—1. That of the Nestorians in Syria; 2. That of the Jews in Egypt.
In the last chapter I have briefly related the persecution of Nestor and his disciples. They bore testimony to the oneness of God, through many sufferings and martyrdoms. They utterly repudiated an Olympus filled with gods and goddesses. "Away from us a queen of heaven!"
Such being their special views, the Nestorians found no difficulty in affiliating with their Saracen conquerors, by whom they were treated not only with the highest respect, but intrusted with some of the most important offices of the state. Mohammed, in the strongest manner, prohibited his followers from committing any injuries against them. Jesuiabbas, their pontiff, concluded treaties both with the Prophet and with Omar, and subsequently the Khalif Haroun-al-Raschid placed all his public schools under the superintendence of John Masue, a Nestorian.
To the influence of the Nestorians that of the Jews was added. When Christianity displayed a tendency to unite itself with paganism, the conversion of the Jews was arrested; it totally ceased when Trinitarian ideas were introduced. The cities of Syria and Egypt were
Under these influences the ferocious fanaticism of the Saracens abated, their manners were polished, their thoughts elevated. They overran the realms of Philosophy and Science as quickly as they had overrun the provinces of the Roman Empire. They abandoned the fallacies of vulgar Mohammedanism, accepting in their stead scientific truth.
In a world devoted to idolatry, the sword of the Saracen had vindicated the majesty of God. The doctrine of fatalism, inculcated by the Koran, had powerfully contributed to that result. "No man can anticipate or postpone his predetermined end. Death will overtake us even in lofty towers. From the beginning God hath settled the place in which each man shall die." In his figurative language the Arab said: "No man can by flight escape his fate. The Destinies ride their horses by night. . . . Whether asleep in bed or in the storm of battle, the angel of death will find thee." "I am convinced," said Ali, to whose wisdom we have already referred—"I am convinced that the affairs of men go by divine decree, and not by our administration." The Mussulmen are those who submissively resign them
This dark doctrine prepared its devotees for the accomplishment of great things—things such as the Saracens did accomplish. It converted despair into resignation, and taught men to disdain hope. There was a proverb among them that "Despair is a freeman, Hope is a slave."
But many of the incidents of war showed plainly that medicines may assuage pain, that skill may close wounds, that those who are incontestably dying may be snatched from the grave. The Jewish physician became a living, an accepted protest against the fatalism of the Koran. By degrees the sternness of predestination was mitigated, and it was admitted that in individual life there is an effect due to free-will; that by his voluntary acts man may within certain limits determine his own course. But, so far as nations are concerned, since they can yield no personal accountability to God, they are placed under the control of immutable law.
In this respect the contrast between the Christian and the Mohammedan nations was very striking: The Christian was convinced of incessant providential interventions; he believed that there was no such thing as law in the government of the world. By prayers and entreaties he might prevail with God to change the current of affairs, or, if that failed, he might succeed with Christ, or perhaps with the Virgin Mary, or through the intercession of the saints, or by the influence of their relics or bones. If his own supplications were unavailing, he might obtain his desire through the intervention
Coincidently with this change of opinion as to the government of individual life, there came a change as respects the mechanical construction of the world. According to the Koran, the earth is a square plane, edged with vast mountains, which serve the double purpose of balancing it in its seat, and of sustaining the dome of the sky. Our devout admiration of the power and
These ideas, which indeed are not peculiar to Mohammedanism, but are entertained by all men in a certain stage of their intellectual development as religious revelations, were very quickly exchanged by the more advanced Mohammedans for others scientifically correct. Yet, as has been the case in Christian countries, the advance was not made without resistance on the part of the defenders of revealed truth. Thus when Al-Mamun, having become acquainted with the globular form of the earth, gave orders to his mathematicians and astronomers to measure a degree of a great circle upon it, Takyuddin, one of the most celebrated doctors of divinity of that time, denounced the wicked khalif, declaring that God would assuredly punish him for presumptuously interrupting the devotions of the faithful by encouraging and diffusing a false and atheistical philosophy among them. Al-Mamun, however, persisted. On the shores of the Red Sea, in the plains of Shinar, by the aid of an astrolabe, the elevation of the pole above the horizon was determined at two stations on the same meridian, exactly one degree apart. The distance between the two stations was then measured, and found to be two hundred thousand Hashemite cubits; this gave for the entire circumference of the earth about twenty-four thousand of our miles, a determination not far from the truth. But, since the spherical
It is remarkable how quickly the ferocious fanaticism of the Saracens was transformed into a passion for intellectual pursuits. At first the Koran was an obstacle to literature and science. Mohammed had extolled it as the grandest of all compositions, and had adduced its unapproachable excellence as a proof of his divine mission. But, in little more than twenty years after his death, the experience that had been acquired in Syria, Persia, Asia Minor, Egypt, had produced a striking effect, and Ali the khalif reigning at that time, avowedly encouraged all kinds of literary pursuits. Moawyah, the founder of the Ommiade dynasty, who followed in 661, revolutionized the government. It had been elective, he made it hereditary. He removed its seat from Medina to a more central position at Damascus, and entered on a career of luxury and magnificence. He broke the bonds of a stern fanaticism, and put himself forth as a cultivator and patron of letters. Thirty years had wrought a wonderful change. A Persian satrap who had occasion to pay homage to Omar, the second khalif, found him asleep among the beggars on the steps of the Mosque of Medina; but foreign envoys who had occasion to seek Moawyah, the sixth khalif, were presented to him
In less than a century after the death of Mohammed, translations of the chief Greek philosophical authors had been made into Arabic; poems such as the "Iliad" and the "Odyssey," being considered to have an irreligious tendency from their mythological allusions, were rendered into Syriac, to gratify the curiosity of the learned. Almansor, during his khalifate (A. D. 753-775), transferred the seat of government to Bagdad, which he converted into a splendid metropolis; he gave much of his time to the study and promotion of astronomy, and established schools of medicine and law. His grandson, Haroun-al-Raschid (A. D. 786), followed his example, and ordered that to every mosque in his dominions a school should be attached. But the Augustan age of Asiatic learning was during the khalifate of Al-Mamun (A. D. 813-832). He made Bagdad the centre of science, collected great libraries, and surrounded himself with learned men.
The elevated taste thus cultivated continued after the division of the Saracen Empire by internal dissensions into three parts. The Abasside dynasty in Asia, the Fatimite in Egypt, and the Ommiade in Spain, became rivals not merely in politics, but also in letters and science.
In letters the Saracens embraced every topic that can amuse or edify the mind. In later times, it was their boast that they had produced more poets than all other nations combined. In science their great merit consists in this, that they cultivated it after the manner of the Alexandrian Greeks, not after the manner of the European Greeks. They perceived that it can never be advanced by mere speculation; its only sure progress
For the establishment and extension of the public libraries, books were sedulously collected. Thus the khalif Al-Mamun is reported to have brought into Bagdad hundreds of camel-loads of manuscripts. In a treaty he made with the Greek emperor, Michael III., he stipulated that one of the Constantinople libraries should be given up to him. Among the treasures he thus acquired was the treatise of Ptolemy on the mathematical construction of the heavens. He had it forthwith translated into Arabic, under the title of "Al-magest." The collections thus acquired sometimes became very large; thus the Fatimite Library at Cairo contained one hundred thousand volumes, elegantly transcribed
There was in every great library a department for the copying or manufacture of translations. Such manufactures were also often an affair of private enterprise. Honian, a Nestorian physician, had an establishment of the kind at Bagdad (A. D. 850). He issued versions of Aristotle, Plato, Hippocrates, Galen, etc. As to original works, it was the custom of the authorities of colleges to require their professors to prepare treatises on prescribed topics. Every khalif had his own historian. Books of romances and tales, such as "The Thousand and One Arabian Nights' Entertainments," bear testimony to the creative fancy of the Saracens. Besides these, there were works on all kinds of subjects—history, jurisprudence, politics, philosophy, biographies not only of illustrious men, but also of celebrated horses and camels. These were issued without any censorship or restraint, though, in later times, works on theology required a license for publication. Books of reference abounded, geographical, statistical, medical, historical
The Saracen Empire was dotted all over with colleges. They were established in Mongolia, Tartary, Persia, Mesopotamia, Syria, Egypt, North Africa, Morocco, Fez, Spain. At one extremity of this vast region, which far exceeded the Roman Empire in geographical extent, were the college and astronomical observatory of Samarcand, at the other the Giralda in Spain. Gibbon, referring to this patronage of learning, says: "The same royal prerogative was claimed by the independent emirs of the provinces, and their emulation diffused the taste and the rewards of science from Samarcand and Bokhara to Fez and Cordova. The vizier of a sultan consecrated a sum of two hundred thousand pieces of gold to the foundation of a college at Bagdad, which he endowed with an annual revenue of fifteen thousand dinars. The fruits of instruction were communicated, perhaps, at different times, to six thousand disciples of every degree, from the son of the noble to that of the mechanic; a sufficient allowance was provided for the indigent scholars, and the merit or industry of the professors was repaid with adequate stipends. In every city the productions of Arabic literature were copied and collected, by the curiosity of the studious and the vanity of the rich." The superintendence of these schools was committed with noble liberality sometimes to Nestorians, sometimes to Jews. It mattered not in what country a man was born, nor what
After the example of the medical college of Cairo, other medical colleges required their students to pass a rigid examination. The candidate then received authority to enter on the practice of his profession. The first medical college established in Europe was that founded by the Saracens at Salerno, in Italy. The first astronomical observatory was that erected by them at Seville, in Spain.
It would far transcend the limits of this book to give an adequate statement of the results of this imposing scientific movement. The ancient sciences were greatly extended—new ones were brought into existence. The Indian method of arithmetic was introduced, a beautiful invention, which expresses all numbers by ten characters, giving them an absolute value, and a value by position, and furnishing simple rules for the easy performance of all kinds of calculations. Algebra, or universal arithmetic—the method of calculating indeterminate quantities, or investigating the relations that subsist among quantities of all kinds, whether arithmetical or geometrical—was developed from the germ that Diophantus had left. Mohammed Ben Musa furnished the solution of quadratic equations, Omar Ben Ibra him that of cubic equations. The Saracens also gave to trigonometry its modern form, substituting sines for chords, which had been previously used; they elevated
In astronomy, they not only made catalogues, but maps of the stars visible in their skies, giving to those of the larger magnitudes the Arabic names they still bear on our celestial globes. They ascertained, as we have seen, the size of the earth by the measurement of a degree on her surface, determined the obliquity of the ecliptic, published corrected tables of the sun and moon fixed the length of the year, verified the precession of the equinoxes. The treatise of Albategnius on "The Science of the Stars" is spoken of by Laplace with respect; he also draws attention to an important fragment of Ibn-Junis, the astronomer of Hakem, the Khalif of Egypt, A. D. 1000, as containing a long series of observations from the time of Almansor, of eclipses, equinoxes, solstices, conjunctions of planets, occultations of stars—observations which have cast much light on the great variations of the system of the world. The Arabian astronomers also devoted themselves to the construction and perfection of astronomical instruments, to the measurement of time by clocks of various kinds, by clepsydras and sun-dials. They were the first to introduce, for this purpose, the use of the pendulum.
In the experimental sciences, they originated chemistry; they discovered some of its most important reagents—sulphuric acid, nitric acid, alcohol. They applied that science in the practice of medicine, being the first to publish pharmacopœias or dispensatories, and to include in them mineral preparations. In mechanics, they had determined the laws of falling bodies, had
The effects of this scientific activity are plainly perceived in the great improvements that took place in many of the industrial arts. Agriculture shows it in better methods of irrigation, the skillful employment of manures, the raising of improved breeds of cattle, the enactment of wise codes of rural laws, the introduction of the culture of rice, and that of sugar and coffee. The manufactures show it in the great extension of the industries of silk, cotton, wool; in the fabrication of cordova and morocco leather, and paper; in mining, casting, and various metallurgic operations; in the making of Toledo blades.
Passionate lovers of poetry and music, they dedicated much of their leisure time to those elegant pursuits. They taught Europe the game of chess; they gave it its taste for works of fiction—romances and novels. In the graver domains of literature they took delight: they had many admirable compositions on such subjects as the instability of human greatness; the consequences of irreligion; the reverses of fortune; the origin, duration,
