Abu Bakr Muhammad ibn Zakariya' al-Razi (Rhazes)

• A physician learned in philosophy as well as music and alchemy.
• The most sought after of all his compositions was The Comprehensive Book on Medicine (Kitab al-Hawi fi al-tibb) -- a large private notebook or commonplace book into which he placed extracts from earlier authors regarding diseases and therapy and also recorded clinical cases of his own experience.
• Arranged by disease
• Meticulous about citing his sources
• The clinical cases, while not unique, are the most numerous and varied in the Islamic medieval medical literature.
• Known as Rhazes in Europe
• The Comprehensive Book on Medicine was translated to Latin in 1279
• It became one of the most widely read medieval medical manuals in Europe, and the ninth chapter, on therapeutics, frequently circulated by itself under the title Liber nonus ad Almansorem. In the Renaissance many editions of it were printed with commentaries by the prominent physicians of the day, such as Andreas Vesalius.
• Book on Smallpox and Measles - Kitab fi al-jadari wa-al-hasbah – was translated in the 18^th Century
• Among al-Razi's smaller medical tracts were treatises on colic, on stones in the kidney and bladder, diabetes, and a cornucopia of other things.
• Al-Razi displayed a primary interest in therapeutics, lacking the concern of later writers for refining the classification of symptoms. He was not in such awe of Galen that he refrained from correcting him, but his criticism was in the areas of logic and clinical applications.
