Not only had the Arabians laid the foundations of culture and learning through their own evolution, but they had borrowed much from other Oriental countries. Their contact with learning of the Far East, of Palestine, of Egypt, of the Greeks, and of the Italians, had given them an opportunity to absorb most of the elements of ancient culture. Having borrowed these products, they were able to combine them and use them in building an empire of learning in Spain. If their own subtle genius was not wanting in the combination of the knowledge of the ancients, and in its use in building up a system, neither lacked they in original conception, and on the early foundation they built up a superstructure of original knowledge. They advanced learning in various forms, and furnished means for the advancement of civilization in the west. _The Foundations of Science and Art_.--In the old caliphates of Bagdad and Damascus there had developed great interest in learning. The foundation of this knowledge, as has been related, was derived from the Greeks and the Orientals. It is true that the Koran, which had been accepted by them as gospel and law, had aroused and inspired the Arabian mind to greater desires for knowledge. Their knowledge, however, could not be set by the limitations of the Koran, and the desire {308} for achievement in learning was so great that scarcely a century had passed after the burning of the libraries of Alexandria before all branches of knowledge were eagerly cultivated by the Arabians. They ran a rapid course from the predominance of physical strength and courage, through blind adherence to faith, to the position of superior learning. The time soon came when the scholar was as much revered as the warrior. In every conquered country the first duty of the conquerors was to build a mosque in which Allah might be worshipped and his prophet honored. Attached to this mosque was a school, where people were first taught to read and write and study the Koran. From this initial point they enlarged the study of science, literature, and art, which they pursued with great eagerness. Through the appreciation of these things they collected the treasures of art and learning wherever they could be found, and, dwelling upon these, they obtained the results of the culture of other nations and other generations. From imitation they passed to the field of creation, and advances were made in the contributions to the sum of human knowledge. In Spain schools were founded, great universities established, and libraries built which laid the permanent foundation of knowledge and art and enabled the Arab-Moors to advance in science, art, invention, and discovery.
