The civilized world is dotted over with theological seminaries, the teachers in which are considered to be men well educated in the learning of ancient and modern times. The avowed purpose of these institutions is to teach the facts, philosophy and history of the so-called Christian religion, yet not a teacher in these institutions can be found who dares to assert the stupendous fact that from the time of the apostles to the ninth century science, literature and philosophy were well nigh extinct. During all this time, with the exception of Jewish and Saracen writers, scarcely a work can be found of sufficient merit to rescue the name of the author from oblivion. Let the skeptic answer this question: Why was it that when the voice of inspiration was hushed and the gospel and its ordinances taken from the earth, there fell upon it an intellectual stagnation, an invisible atmosphere of oppression, ready to crash down morally and physically whatever provoked its weight? Thus the dreary and weary centuries rolled on, until a nation, hitherto considered barbarous, yet of the seed of Abraham, and heirs of the promises made to Ishmael and Esau, aroused society from the hideous fanaticism, ignorance and superstition into which apostasy had plunged it.
If it be true that the Saracens burned the Alexandrian library, it must be considered that this was the act of an uneducated general and the vengeance of the soldiery after a terrible siege, rather than the deliberate policy of the government. Within twenty-five years from the death of Mahomet the Caliphs had become famous for their patronage of learning. Ali, the fourth Caliph and son-in-law of Mahomet, used to say, "The world is sustained by four things only: the prayers of the good, the learning of the wise, the justice of the great, and the valor of the brave." This sentiment was echoed and re-echoed until it became an honored maxim in the minds of millions.
Under the influence of Jewish, Nestorian and Saracen teachers the manners of the Saracens became more polished and their thoughts more elevated. They made conquests in the realms of science, literature and the arts as quickly as in the provinces of the Roman empire.
For example, Almansor, who reigned as Caliph from A. D. 753 to 775, established the University of Bagdad, and endowed it with two hundred thousand pieces of gold, and an annual revenue of fifteen thousand dinars, equal in commercial value to one hundred and twenty thousand dollars of our money. He invited thither learned men from every land, irrespective of their religious opinions. By these men were founded celebrated schools of mathematics, astronomy, chemistry, medicine, law and languages.
His grand-son, Haroun-al-Raschid, ordered in A. D. 786, that a public school should be attached to every mosque in his dominions. This was more than seven hundred years before the establishment of the famous parish schools of Scotland.
The Caliph-al-Mamun, in A. D. 813, founded the great medical college of Cairo, which required students to pass a rigid examination before receiving authority to enter on the practice of their profession. At this college we have the first account of dissecting human bodies for the purpose of ascertaining the nature and locality of diseases, and the first circulating library for students. These books were bound according to the modern form, which then began to be used among the Saracens in place of the ancient form of the scroll.
By the means just mentioned, the ancient sciences were greatly extended and new ones introduced. To the Saracens we are indebted for our present system of arithmetical notation. If, for example, we wish to multiply 1882 by 125 and then attempt it by the ancient method MDCCCLXXXII., multiplied by CXXV., we shall soon perceive the vast superiority of the Arabic system over that formerly in use. No wonder, then that under the ancient system those who were engaged in solving difficult mathematical problems were frequently styled "sweating calculators."
In this case as in many others the Arab has left his impress on this science. For instance, our word cipher, and kindred words, such as decipher, ciphering, etc., are derived from the word tsaphara, or ciphra, the name for the 0 in the Arabic language.
In experimental sciences, they originated chemistry and discovered the nature and properties of sulphuric acid, nitric acid, alcohol and many other chemical agents. From their schools of medicine may be traced such words as julep, syrup, elixir, alchemy, etc. To them we are indebted for algebra, or universal arithmetic, and in astronomy they made such advances that many constellations and stars of the first magnitude still retain the Arabic names.
In geography, the Saracens made important discoveries. Hitherto mankind had been taught that the earth was a vast plain, surmounted by an immense vault commonly called the sky. They were the first to prove that the earth is a vast globe, or ball; and in order to determine its size, they first ascertained on the level shore of the Red sea the exact position of the North Star. Then traveling directly north until it had attained another degree of elevation, they measured the distance between these points, and multiplying the result by three hundred and sixty (the number of degrees in a circle), they found the earth to be nearly twenty-five thousand miles in circumference. So accurate were their observations and measurements that the best calculators of recent times differ from them less than one-third of a mile.
Five hundred years later the Roman pontiffs were excommunicating and torturing those who taught the rotundity of the earth. While Catholic monks were teaching, in all its absurdity, the flatness of the earth, and how it rested on a vast rock, and that rock on another and so on all the way down to the bottom(?), the Saracens were teaching geography from globes in their common schools. It cost a long struggle through several centuries, "with spiritual wickedness in high places," before the truth finally triumphed.
European historians have generally given great credit to Pope Gregory for the invention and adoption of the Gregorian calendar and a more accurate method of measuring the exact length of the civil year. Yet, Gregory only adopted what had been discovered and taught by Thebit-Ben-Corrah, the Saracen astronomer, more than five hundred years before, and what Gregory himself had learned in youth while attending a Saracen university.
The mariner's compass was well known to the Arabs, who probably brought it from China and introduced it to the nations of Europe. From this we may correctly infer that they were a maritime people. In fact, long before the time of Mahomet, Arabian merchants were acquainted with the Indies, and even China and the eastern coast of Africa as far south as Madagascar.
Alhazin, who wrote about A. D. 1080, made the great discovery of atmospheric refraction—that a ray of light when it touches the atmosphere is bent from a straight line; and consequently we see the sun before it rises and after it sets, in the same manner that an object lying at the bottom of a bucket filled with water appears in quite a different position from that in which it really is. He was the first to give that beautiful and scientific explanation of twilight, viz., the refraction of light, which is still regarded by modern scientists as the true one. He even attempted to ascertain the height of the atmosphere, which he estimated to be about fifty-eight and a half miles. This philosopher also wrote a treatise on weights and measures, and introduced that excellent system of weighing by means of a small, movable weight attached to the longer arm of a lever, as in our modern scales or steelyards. The Arabian astronomer, Ebn-Junis, was the first who made use of the pendulum in the machinery of clocks for the accurate measurement of the hours.
In the golden age of the Saracen empire, there were colleges in every part of its vast dominions. So numerous were these institutions, that more than six thousand students received instructions in them annually. In the far east were the college and astronomical observatory of Samercand; while in the western province of Andalusia were the famous school and observatory of Giralda.
The first medical college established in Europe was that founded by the Saracens at Salerno, in Italy; the first famous school of mathematics and astronomy was that established by them at Seville, in Spain.
Among them, learning was not confined to the rich, but every class received its benefits. The teachers of their colleges were paid liberal salaries for their services, and an allowance was made for indigent scholars, so that the son of the mechanic could graduate from the same class as the heirs of the Caliphs.
At first glance it seems remarkable
