Abu al-Qasim Khalaf ibn al-Abbas al-Zahrawi, known in the West as Albucasis, was the greatest surgeon of the medieval world. He lived and practiced in Córdoba during the height of Islamic civilization in Spain. His 30-volume medical encyclopedia, Kitab al-Tasrif (The Method of Medicine), devoted its final volume entirely to surgery and surgical instruments — including detailed illustrations of over 200 instruments he designed. Many of these instruments (such as the surgical hook, bone saw, and forceps) are still used in modified forms today. Al-Zahrawi described surgical procedures for cataracts, tonsillectomies, and cauterization. His work was translated into Latin and remained the primary surgical reference in European universities for five centuries.
