Spain owed much to the Moor, however, from other causes. The Arabs were a learned and refined race. They built cities, palaces, and mosques; they founded universities, they encouraged learning. The most eminent scholars came from the East to grace their schools, and introduced a spirit of inquiry and a love of knowledge which survived their power. Abdorrhaman III. founded the university at Cordova. He established schools and collected a library, it is said, to the extent of six hundred thousand volumes. The blessings of civilisation was fostered by the Omajad dynasty. Mahometanism never flourished with such true glory as under the Spanish caliphs. One of the most remarkable circumstances of this era is, the prosperity and learning of the Jews settled in Spain. Persecuted by the Goths[4], this hapless nation doubtless welcomed the Moors gladly; and finding toleration under their rule, and their schools open to them, they flocked to the universities of Cordova and Toledo in such numbers, that one Jewish writer tells us that there were twelve thousand Israelitish students at Toledo; and they gave evidence of the perseverance, sagacity, and talent which belong to that people, and which, fostered by the blessed spirit of toleration, bore worthy fruit. A succession of Hebrew scholars may be traced from the tenth to the fifteenth centuries. De Castro gives an account of seven hundred different works. Every Jew could read. The higher classes flourished in glory and prosperity, so that many of the noblest Spanish families include Jewish sprouts in the tree of their genealogy. Even to this day the Jews' sons of those driven from Spain to this country remember their Spanish renown, and have preserved a recollection of its language.
