We have underestimated the importance of 800 years of Islamic society and culture in Spain between the 8th and 15th centuries. The contribution of Muslim Spain to the preservation of classical learning during the Dark Ages, and to the first flowerings of the Renaissance, has long been recognised. But Islamic Spain was much more than a mere larder where Hellenistic knowledge was kept for later consumption by the emerging modern Western world. Not only did Muslim Spain gather and preserve the intellectual content of ancient Greek and Roman civilisation, it also interpreted and expanded upon that civilisation, and made a vital contribution of its own in so many fields of human endeavour - in science, astronomy, mathematics, algebra (itself an Arabic word), law, history, medicine, pharmacology, optics, agriculture, architecture, theology, music. Averroes and Avenzoor, like their counterparts Avicenna and Rhazes in the East, contributed to the study and practice of medicine in ways from which Europe benefited for centuries afterwards.
Islam nurtured and preserved the quest for learning. In the words of the tradition, 'the ink of the scholar is more sacred than the blood of the martyr'. Cordoba in the 10th century was by far the most civilised city of Europe. We know of lending libraries in Spain at the time King Alfred was making terrible blunders with the culinary arts in this country. It is said that the 400,000 volumes in its ruler's library amounted to more books than all the libraries of the rest of Europe put together. That was made possible because the Muslim world acquired from China the skill of making paper more than 400 years before the rest of non-Muslim Europe. Many of the traits on which modern Europe prides itself came to it from Muslim Spain. Diplomacy, free trade, open borders, the techniques of academic research, of anthropology, etiquette, fashion, various types of medicine, hospitals, all came from this great city of cities.
Medieval Islam was a religion of remarkable tolerance for its time, allowing Jews and Christians the right to practise their inherited beliefs, and setting an example which was not, unfortunately, copied for many centuries in the West. The surprise, ladies and gentlemen, is the extent to which Islam has been a part of Europe for so long, first in Spain, then in the Balkans, and the extent to which it has contributed so much towards the civilisation which we all too often think of, wrongly, as entirely Western. Islam is part of our past and our present, in all fields of human endeavour. It has helped to create modern Europe. It is part of our own inheritance, not a thing apart.
