When he arose next morning Fernando paid a visit to the great mosque of the city. It was the first time he had entered a Moorish place of worship, and he was struck by the circumstance that the atmosphere which prevailed within it closely resembled that to be found in a Christian cathedral. The same hushed silence was distinctly noticeable. Here and there stood a mullah, or teacher, instructing his disciples in Mohammedan law and ritual, and this Fernando was rather pleased than otherwise to notice, as direct instruction in the tenets of the Christian faith was but seldom to be procured in the churches of his own country. Another thing he could not but observe was the manifest learning and erudition of the speakers. This seemed to him far in advance of the monkish accomplishments of his own priestly subjects, whose learning was of the most slender description, and but few of whom were able to write, and he was deeply interested to find that in an annexe to the mosque, which was fitted as a scrivenry or writing-room, a number of mullahs, old and young, sat at desks writing swiftly in the Arabic script and engaged in the multiplication of copies of the Koran and other works of a religious nature. From the mosque Fernando speedily found his way to the university, and was soon lost in wonder at the rich intellectual life which flourished there. In one room a white-robed teacher was lecturing upon the practice of medicine with an acumen and ability he had never heard equalled. His knowledge of drugs and chemistry and of the properties of plants and herbs appeared to be both wide and exact, and when Fernando thought upon the wretched leeches to whom so many of the lives of his subjects annually paid forfeit he experienced a deep feeling of shame that these swarthy yet studious foreigners were so easily able to eclipse them in both theory and application. But he was acute enough to discern that the lecturer spoke of the medical art as a thing the principles of which were already fixed beyond the power of expansion. He spoke of experiment in the past tense, and all his references were to the great teachers of the old world, to Galen and Hippocrates, to Avicenna and to Rhazes. If he did chance to allude to the teachers of his own day, it was in rather an apologetic manner, and by no means in a complimentary sense. Antiquity was everything to him, and the tenets of the old masters of medicine appeared to him quite as sacred in their way as the words of the Prophet himself.
