No period of European history is more astonishing than the records of the triumphant progress of the Arab power under the influence of the faith of Islam. From the earliest times this grand Semitic race was distinguished for learning of a certain character, for gravity, piety, superstition, a poetic imagination, and eloquence. Centuries of independence, jealously guarded, and innumerable local feuds made the material of perfect soldiers, and when Mohammed had grafted on the native religious character his own faith and missionary zeal the Arab army, the Saracens, as they came to be called, filled with fanatic fervour, and utterly indifferent to death, or, rather, eager for it as the introduction to the Paradise which their prophet had seen and told them of, formed such an irresistible force as on a small scale has only been reproduced by Cromwell in our nation. But the rapidity of the conquests of Mohammedanism was perhaps less remarkable than the extraordinary assimilation of ancient learning and the development of new science among these hitherto unlettered Arabs. Mohammed was born in the year 569 of our era. The Koran was the first substantial piece of Arabic literature. Alexandria was taken and Egypt conquered by the Moslems under Amrou in A.D. 640, Persia and Syria having been previously subdued. Amrou was himself disposed to yield to the solicitations of some Greek grammarians, who implored him to spare the great Library of the city, the depository of the learning of the ancient world. But he considered it necessary to refer the request to the Caliph Omar. The reply of the Commander of the Faithful is one of the most familiar of the stories in Gibbon’s fascinating history. “If the writings support the Koran they are superfluous; if they oppose it they are pernicious; burn them.” It is declared that the papers and manuscripts served as fuel for the baths of the city for six months. The destruction of the Alexandrian Library is often alluded to as a signal triumph of barbarism over civilisation. Gibbon cynically remarks that “if the ponderous mass of Arian and Monophysite controversy were indeed consumed in the public baths a philosopher may allow with a smile that it was ultimately devoted to the benefit of mankind.” But at least the spirit which animated Omar in 640 may be noted for comparison with the encouragement of learning which was soon to characterise the Arab rulers. Only a lifetime later, in A.D. 711, the sons of the Alexandrian conquerors invaded Spain, and within the same century made their western capital, Cordova, the greatest centre of learning, civilisation, and luxury in Europe. The following quotation from Dr. Draper’s “History of the Intellectual Development of Europe” will give an idea of this achievement:
