Abu'l Qasim al-Zahrawi's 11th century medical encyclopedia: Kitab al-Tasrif
The Kitab at-Tasrif (Arabic: كتاب التصريف لمن عجز عن التأليف) (The Method of Medicine) was 30-volume Arabic encyclopedia on medicine and surgery, written near the year 1000 by Abu al-Qasim al-Zahrawi (Abulcasis). It is available in translation.
The Kitab al-Tasrif took Al-Zahrawi over 50 years to complete. It contains information about a wide variety of illnesses, injuries, medical conditions, treatments, and surgical procedures. It describes over 200 different surgical instruments, and it has been said that almost 90% of surgical instruments being used today were demonstrated by Abulcasis. Surgeons continued to rely on the Kitab al-Tasrif well into the 1700s; some of Al-Zahrawi’s surgical procedures are still being used to this very day. This book was read by medical students at major universities in Europe until the late 1800s.
