Al Tabari, (810 – 855) wrote a book known as ‘The Paradise of Wisdom,’ in 850, which was based largely upon the earlier works of Galen and Hippocrates, but it also included an appendix with translations from Indian sources.

Like many physicians of the time, his work involved providing better and more detailed encyclopedias, containing the medical knowledge available at that time. Sadly, it is believed that most of his works are lost and are only referred to as quoted in later texts.
Al Tabari’s work was made up of nine discourses, each divided into many chapters. These were:
I. General pathology, symptoms of internal disorders and general therapeutic principles II. Diseases and conditions affecting the head III. Diseases of the eyes, nose, face and mouth IV. Nervous diseases V. Diseases of the chest and throat
VI. Diseases of the stomach VII. Diseases of the liver VIII. Diseases of the heart and lungs IX. Diseases of the intestines, urinary tract and genitals
Al Hakm (Died 840) wrote the earliest known book in the medical sciences in the Islamic world and it drew heavily upon Greek sources, including information about physiology, surgery and general healthcare, amongst other sections.
Yuhanna Ibn Masawyh (777 – 857) was regarded as amongst the great translators of work from Greek into Arabic, but he also acted as a physician to the Caliphs and served at a hospital.
He is believed to have written the works ‘Disorders of the Eye’ and ‘Knowledge of the Oculist Examinations’ as well as Kita al Mushajjar al-Kabir, a short work including descriptions, diagnosis, symptoms and treatments of diseases.
Hunayan ibn Nishaq (808-873), known as Johannitus in the West, was one of the titans of Islamic medicine and was a prominent author of medical texts, covering a variety of disciplines.
As well as extensive translation work, he wrote a book called ‘The Book of Introduction to Medicine,’ which drew heavily upon Galen but also, included many unique and novel additions. His work was probably the first Islamic medical text translated into Latin.
