"The library of Alexandria was burnt by the Moslimin, because, according to the instructions of Omar, the Koran only was the book of books, and all knowledge not contained in it was vain and useless. The library at Tripoli was consumed by the Christians, because it contained, for the most part, nothing but the Koran, and the works written on it. At Alamut the Koran was preserved by Jowaini, and the philosophical works written against it, doomed to destruction; and at Fas, a century before, an auto da fe of theological books was held by Sultan Yakub. Had these two alone been lost, there would not be so much reason to complain; but with them, the conflagrations of Alexandria and Alamut swept away treasures of Grecian, Egyptian, Persian, and Indian philosophy."
