His works had reached Europe in a somewhat roundabout way. They had gone from Greece to Alexandria. They had then been translated from the Greek into the Arabic language by the Mohammedans who conquered Egypt in the seventh century. They had followed the Moslem armies into Spain and the philosophy of the great Stagirite (Aristotle was a native of Stagira in Macedonia) was taught in the Moorish universities of Cordova. The Arabic text was then translated into Latin by the Christian students who had crossed the Pyrenees to get a liberal education and this much travelled version of the famous books was at last taught at the different schools of northwestern Europe. It was not very clear, but that made it all the more interesting.
