Death of Ibn Zuhr (Avenzoar)

# Death of Ibn Zuhr (Avenzoar)

Abu Marwan Abd al-Malik ibn Abi al-Ala ibn Zuhr al-Iyadi (484-557 AH / 1091-1162 CE), known in the Latin West as Avenzoar, was the greatest physician of al-Andalus and one of the most important medical figures of the Islamic world. A member of a distinguished Andalusian medical dynasty, he combined extensive clinical practice with significant medical scholarship and stood as the practical complement to Ibn Rushd's philosophical approach to medicine.

Medical Dynasty

The Banu Zuhr family produced physicians for several generations. Abu Marwan's father, grandfather, and several of his children were also accomplished physicians. His daughter and granddaughter are among the few medieval Muslim women recorded as practicing surgery and obstetrics.

Abu Marwan served as court physician to the Almoravid rulers of al-Andalus and later to the early Almohad dynasty, though his relationship with the Almohads was troubled: he reportedly spent time imprisoned under the Almohad ruler Ibn Tumart.

Al-Taysir fil-Mudawat wal-Tadbir

Ibn Zuhr's most influential work is al-Taysir fil-Mudawat wal-Tadbir (The Book of Simplification Concerning Therapeutics and Diet). It was written at the request of Ibn Rushd (Averroes), who planned to write a comprehensive medical encyclopedia and asked Ibn Zuhr to handle the practical therapeutic section while he handled the theoretical. The two books were intended as complements: Ibn Rushd's Kulliyyat (Generalities, known in Latin as Colliget) covered medical theory, while al-Taysir covered practical treatment.

Al-Taysir is notable for its detailed clinical descriptions based on actual patient observation. Ibn Zuhr described the symptoms and treatments for numerous conditions with a precision that went beyond what the Greek medical authorities had provided.

Significant contributions include:

• A detailed description of mediastinal tumors — the first accurate clinical description in medical history
• Description of pericarditis (inflammation of the sac surrounding the heart)
• The first clear description of the mange mite (Sarcoptes scabiei) as a causative agent of scabies, centuries before its rediscovery in Europe
• Clinical descriptions of pharyngeal paralysis
• Experimental work: he reportedly performed experimental feeding through a tube inserted into the esophagus of a goat to study the possibility of artificial nutrition

Emphasis on Clinical Experience

Ibn Zuhr placed great emphasis on clinical observation over pure theory, in contrast to the more theoretically inclined philosophical physicians. He was known for his willingness to experiment and to base his conclusions on direct patient observation rather than solely on the authority of Galen or Ibn Sina.

He wrote: "The physician must see the patient, and if the patient cannot come to him, he must go to the patient."

Other Works

Al-Iqtisad fil-Islah al-Anfus wal-Ajsad (The Book of the Middle Course Concerning the Reformation of Souls and Bodies) — a shorter medical work covering hygiene, diet, and the maintenance of health in healthy individuals.

Kitab al-Aghdhiya (Book of Foodstuffs) — a pharmacological work on the properties of foods and their medical applications.

Death and Legacy

Ibn Zuhr died in Seville in 557 AH (1162 CE) at approximately 71 years of age. He was buried in Seville.

Al-Taysir was translated into Hebrew in 1280 CE and into Latin by Paravicius in 1280 CE under the title Theisir. Together with Ibn Rushd's Colliget, it was a standard medical text in European universities throughout the medieval period, printed in Venice in 1490 and 1491 CE.

Ibn Zuhr represents the empirical-clinical strand of Islamic medicine at its finest — a complement to the great theoretical synthesizers, and in some respects a forerunner of the clinical observation that would characterize the best of European Renaissance medicine.
