Ibn Sina (Avicenna)

Abu Ali al-Husayn ibn Sina, known in the West as Avicenna, was one of the most significant polymaths of the Islamic Golden Age. Born in Bukhara (modern Uzbekistan), he authored approximately 450 works, of which around 240 survive. His most influential work, the Canon of Medicine (Al-Qanun fi al-Tibb), organized and systematized Greek, Roman, and Islamic medical knowledge into a five-volume encyclopedia. It was used as the primary medical textbook at European universities from the 12th through the 17th century. Ibn Sina recognized the contagious nature of tuberculosis, identified that diseases could spread through water and soil, and described hundreds of medications with their properties. Beyond medicine, he contributed profoundly to philosophy, writing The Book of Healing, a vast philosophical and scientific encyclopedia that covered logic, mathematics, physics, and metaphysics.
