Ibn al-Nafis
ʿAlāʾ al-Dīn Abū al-Ḥasan ʿAlī ibn Abī Ḥazm al-Qarashī (Arabic: علاء الدين أبو الحسن عليّ بن أبي حزم القرشي ), known as Ibn al-Nafīs (Arabic: ابن النفيس), was an Arab polymath whose areas of work included medicine, surgery, physiology, anatomy, biology, Islamic studies, jurisprudence, and philosophy. He is known for being the first to describe the pulmonary circulation of the blood. The work of Ibn al-Nafis regarding the right sided (pulmonary) circulation pre-dates the later work (1628) of William Harvey's De motu cordis. Both theories attempt to explain circulation. The 2nd century Greek physician Galen's theory about the physiology of the circulatory system remained unchallenged until the works of Ibn al-Nafis, who has therefore been described as "the father of circulatory physiology".
As an early anatomist, Ibn al-Nafis also performed several human dissections during the course of his work, making several important discoveries in the fields of physiology and anatomy. Besides his famous discovery of the pulmonary circulation, he also gave an early insight of the coronary and capillary circulations. He was also appointed as the chief physician at al-Naseri Hospital founded by Sultan Saladin. Due to his discoveries, he has been described by some as “the second Avicenna”.
Apart from medicine, Ibn al-Nafis studied jurisprudence, literature and theology. He was an expert on the Shafi'i school of jurisprudence and an expert physician. The number of medical textbooks written by Ibn al-Nafis is estimated at more than 110 volumes.
Ibn al-Nafis was born between 1210 and 1213 to an Arab family probably at a village near Damascus named Karashia, after which his Nisba might be derived. He was said to have descended from the Quraysh tribe. Early in his life, he studied theology, philosophy and literature. Then, at the age of 16, he started studying medicine for more than ten years at the Nuri Hospital in Damascus, which was founded by the Turkoman emir of Aleppo and Damascus, Nur-al Din Muhmud ibn Zanki, in the 12th century. He was contemporary with the famous Damascene physician Ibn Abi Usaibia and they both were taught by the founder of a medical school in Damascus, Al-Dakhwar. Ibn Abi Usaibia does not mention Ibn al-Nafis at all in his biographical dictionary "Lives of the Physicians". The seemingly intentional omission could be due to personal animosity or maybe rivalry between the two physicians.
In 1236, Ibn al-Nafis, along with some of his colleagues, moved to Egypt under the request of the Ayyubid sultan al-Kamil. Ibn al-Nafis was appointed as the chief physician at al-Naseri hospital which was founded by Saladin, where he taught and practiced medicine for several years. One of his most notable students was the famous Christian physician Ibn al-Quff. Ibn al-Nafis also taught jurisprudence at al-Masruriyya Madrassa (Arabic: المدرسة المسرورية). His name is found among those of other scholars, which gives insight into how well he was regarded in the study and practice of religious law.
Ibn al-Nafis lived most of his life in Egypt, and witnessed several pivotal events like the fall of Baghdad and the rise of Mamluks. He even became the personal physician of the sultan Baibars and other prominent political leaders, thus showcasing himself as an authority among practitioners of medicine. Later in his life, when he was 74 years old, Ibn al-Nafis was appointed as the chief physician of the newly founded al-Mansori hospital where he worked for the rest of his life.
Ibn al-Nafis died in Cairo after some days of sickness. His student Safi Abu al-Fat'h composed a poem about him. Prior to his death, he donated his house and library to Qalawun Hospital or, as it was also known, the House of Recovery.
The most voluminous of his books is Al-Shamil fi al-Tibb (The Comprehensive Book on Medicine), which was planned to be an encyclopedia comprising 300 volumes. However, Ibn al-Nafis managed to publish only 80 before his death, and the work was left incomplete. Despite this fact, the work is considered one of the largest medical encyclopedias ever written by one person, and it gave a complete summary of the medical knowledge in the Islamic world at the time. Ibn al-Nafis bequeathed his encyclopedia along with all of his library to the Mansoory hospital where he had worked before his death.
