Among the hospitals of Bagdad was a palatial structure with many rooms and wards, which were furnished in elaborate style. Here the patients were gratuitously provided with food and medicine and regularly visited by the physicians of the city. It was here that Rhazes, the most celebrated Mussulman physician of his time, gave his lectures and founded the great medical school which drew students from all parts of Western Asia. Rhazes is famous not only for his eminence as a physician but also as a voluminous writer on medicine and for having described smallpox nearly nine hundred years before Jenner began his noted investigations on this dread disease. It was, however, the colleges, of which there were more than thirty--“each more magnificent than a palace”--that gave Bagdad its greatest fame in the mediæval world. One of these, called the Nizamiyah, founded by an eminent vizier who was the friend of the poet Omar Khayyám, was, on account of its architectural splendor, and the celebrity of its professional staff, known as the “Mother of the colleges of Bagdad.” Among its most illustrious lecturers were Ghazzali, celebrated as a philosopher and a theologian, and Bohadin, who achieved eminence as a historian, as a statesman, and as the biographer of the Sultan Saladin. The endowment of the Nizamiyah was so princely that it sufficed not only to pay the salaries of the professors but also to pay for the board and tuition of indigent students. Completely eclipsing the Nizamiyah College in its architectural grandeur, sumptuous equipment, and wealth of endowment was the College of the Mustansiriyah--the ruins of which still exist--which was founded by the Caliph Mustansir, the father of Mustasim, who was put to death by Hulago after the destruction of Bagdad. So great was the splendor of this college that it is said to have surpassed any similar institution in Islam. It was not only the most notable seat of learning in Bagdad, but was also its most beautiful and imposing edifice. When one recalls the many gorgeous palaces of the city--many of them costing fabulous sums--one can realize what munificent patrons were Bagdad’s Caliph and men of wealth and how well this fairy capital deserved its reputation as the Orient’s most famous center of science and letters. It had only one rival and that was the famous Ommaied metropolis in Spain, so celebrated for its riches and attractions, its schools and libraries and scholars--a city which Hroswitha, the gifted nun of Gandersheim, has so beautifully described in a single distich: _Corduba famosa, locuples de nomine dicta,_ _Inclyta deliciis, rebus quoque splendida cunctis._
