Ibn Sina (ابن سینا), commonly known as Avicenna in the West (/ˌævɪˈsɛnə, ˌɑːvɪ-/; c. 980 – June 1037), was a Persian[4][5][6][7] polymath who is regarded as one of the most significant physicians, astronomers, philosophers and writers of the Islamic Golden Age,[8] and the father of early modern medicine.[9][10][11] Sajjad H. Rizvi has called Avicenna "arguably the most influential philosopher of the pre-modern era".[12] He was a Muslim Peripatetic philosopher influenced by Greek Aristotelian philosophy. Of the 450 works he is believed to have written, around 240 have survived, including 150 on philosophy and 40 on medicine.[13]
His most famous works are The Book of Healing, a philosophical and scientific encyclopedia, and The Canon of Medicine, a medical encyclopedia[14][15][16] which became a standard medical text at many medieval universities[17] and remained in use as late as 1650.[18]
