Ibn Bajah (known to Europeans under the name of Avempace) was a philosoper and a poet of considerable celebrity, and a native of Saragossa, in Spain. He was attacked by some people for his religious opinions, and represented as an infidel and an atheist, professing the doctrines held by the ancient sages and philosophers. Ibn Khallikan defends Ibn Bajah, and says that these statements were much exaggerated, but adds: 'God, however, knows best what his principles were,' Abul Hassan Ali al-Imam, of Granada, was of opinion that Ibn Bajah was the greatest Arab philosopher after Al-Farabi, and places him higher than Ibn Sina and Al-Ghazali. He left numerous logical, grammatical and political works, and died at Fez in A.D. 1138. Averroes, whose full and correct name is Abul Walid Muhammad bin Rashid, was a celebrated Arab scholar, born at Cordova A.D. 1126, and the author of many writings. He taught in his native town philosophy and medicine, two sciences which appeared for a long time to be inseparable, and the vulgar considered those professing them to be of almost supernatural attainments. The period of Averroes is that of the decadence of Arab dominion in Spain, a period when this great nation also lost the taste for sciences which it had brought to Europe. Considering the prodigious number of works composed by Averroes, who filled at the same time the offices of Imam and Kadi, his entire life must have been one of labour and meditation. He is the author of an Arabic version of Aristotle, but it is not the first which existed in that language, as some of his biographers assert, because this work had been produced already at Baghdad during the brilliant Khalifate of Mamun. There are various manuscripts of Averroes extant treating on physics, pure mathematics, astronomy and astrology, from which it would appear that, in spite of their encyclopaedic attainments, the celebrated men of these times still believed in some popular errors. Science was at that time surrounded by a kind of superstitious halo of respect, to which Averroes, like so many others, is indebted for a good part of his renown. He died A.D. 1198, in the city of Morocco; his corpse was transferred to Cordova and there interred. Medical science had already, under the second Khalif of the house of Abbas (A.D. 754-775), enjoyed the highest honours, which it ever afterwards retained. Great physicians were brought from the Persian hospital of Jondshapur, and between the years A.D. 750 and 850 the number of physicians was considerable, but only the most celebrated will be noticed.
