AVICENNA (IBNU SINA)

Abū ‘Alī al-Ḥusayn ibn ‘Abd Allāh ibn Sīnā, known as Abū Alī Sīnā^[1][2] (Persian: ابوعلی سینا، پورسینا) or, more commonly, Ibn Sīnā^[3] (Arabic: ابن سینا‎) or Pour Sina, but most commonly known in English by his Latinized name Avicenna (Greek: Aβιτζιανός, Avitzianós),^[4] (c. 980 - 1037) was a polymath of Persian^[5] origin and the foremost physician and philosopher of his time.^[6] He was also an astronomer, chemist, geologist, Hafiz, Islamic psychologist, Islamic scholar, Islamic theologian, logician, paleontologist, mathematician, Maktab teacher, physicist, poet, and scientist.^[7].

Ibn Sīnā studied medicine under a physician named Koushyar. He wrote almost 450 treatises on a wide range of subjects, of which around 240 have survived. In particular, 150 of his surviving treatises concentrate on philosophy and 40 of them concentrate on medicine.^[1][8] His most famous works are The Book of Healing, a vast philosophical and scientific encyclopaedia, and The Canon of Medicine,^[9] which was a standard medical text at many medieval universities.^[10] The Canon of Medicine was used as a text-book in the universities of Montpellier and Louvain as late as 1650.^[11]

Ibn Sīnā's Canon of Medicine provides a complete system of medicine according to the principles of Galen (and Hippocrates).^[12][13]

George Sarton, an early author of the history of science, wrote in the Introduction to the History of Science:

One of the most famous exponents of Muslim universalism and an eminent figure in Islamic learning was Ibn Sina, known in the West as Avicenna (981-1037). For a thousand years he has retained his original renown as one of the greatest thinkers and medical scholars in history. His most important medical works are the Qanun (Canon) and a treatise on Cardiac drugs^[14][15]. The 'Qanun fi-l-Tibb' is an immense encyclopedia of medicine. It contains some of the most illuminating thoughts pertaining to distinction of mediastinitis from pleurisy; contagious nature of phthisis; distribution of diseases by water and soil; careful description of skin troubles; of sexual diseases and perversions; of nervous ailments.
