Life
Ali ibn Ridwan was born the son of a baker in Giza. Even before he was 15 years old he began to study medicine and was a practicing physician. He also studied philosophy.
He hired himself out as an astrologer in order to continue his philosophical and medical studies. Also he is known for his observation of the Supernova 1006.
Later he was in the service of the Caliph al -Hakim, and was the captain of the Egyptian doctors of the time. Ali ibn Ridwan wrote several important books on Arabic medicine. To 1051 he wrote Dafe ' Madaar al Abdaan Be Ard Misr - Avoiding damage to the body in the land of Egypt. This work was translated into Latin and later used in the Christian Franks. The second book Al- Oussool fi al Tibb - The principles of medicine was later translated into Hebrew.
He also wrote several short treatises on various medical topics, including about leprosy, elephantiasis, epidemics, dyspnea. He is known for his commentaries on the medical works of Hippocrates, Claudius Ptolemy and Galen '. His comment to Galen ' Ars Parva was translated into Hebrew by Samuel ibn Tibbon. Ali ibn Ridwan changed with the Baghdad physician Ibn Butlan several and partly polemical, controversial writings.
After Alistair Cameron Crombie, he also contributed to the theory of induction.
In the Middle Ages Ali was often depicted as one of the four philosophers.
