Ali ibn Sahl Rabban al-Tabari

Ali ibn Sahl Rabban al-Tabari (c. 838 – c. 870 CE; also given as 810–855 or 808–864 also 783–858 ), was a Persian Muslim scholar, physician and psychologist, who produced one of the first Islamic encyclopedia of medicine titled Firdaws al-Hikmah ("Paradise of Wisdom"). Ali ibn Sahl spoke Syriac and Greek, the two sources of the medical tradition of Antiquity which had been lost by medieval Europe, and transcribed in meticulous calligraphy. His most famous student was the physician and alchemist Abu Bakr al-Razi (c. 865–925). Al-Tabari wrote the first encyclopedic work on medicine. He lived for over 70 years and interacted with important figures of the time, such as Muslim caliphs, governors, and eminent scholars. Because of his family's religious history, as well as his religious work, al-Tabarī was one of the most controversial scholars. He first discovered that pulmonary tuberculosis is contagious.

Outside the rational sciences, as a convert from Christianity to Islam he was also involved in interreligious polemics, writing two works critical of his former religion, al-Radd ´alā l-Nasārā (The Refutation of the Christians) and Kitāb al-dīn wa-l-dawla (The Book of Religion and Empire), both of which having been published by Brill in 2016 in a single book, The Polemical Works of ʿAlī al-Ṭabarī.

Life
Ali came from a Persian or Syriac family of Tabaristan Amol (hence al-Tabari – "from Tabaristan"). Hossein Nasr states that he was a convert to Islam from Zoroastrianism, however Sami K. Hamarneh and Franz Rosenthal state he was a convert from Christianity. His father Sahl ibn Bishr was a state official, highly educated and well respected member of the Syriac community. Rabbān received his educational bases in the medical field, natural sciences, calligraphy, mathematics, philosophy and literature from his father Sahl.

The Abbasid caliph al-Mu'tasim (833–842) took him into the service of the court, which he continued under al-Mutawakkil (847–861). Ali ibn Sahl was fluent in Syriac and Greek, the two sources for the medical tradition of antiquity, and versed in fine calligraphy.

Works
Although few of them are still found today, al-Tabarī left 12 books to mankind. Most of them were about medicine. In addition to medicine, he was known as a scholar of philosophy, mathematics and astronomy.
 * 1) His Firdaws al-Hikmah ("Paradise of Wisdom"), which he wrote in Arabic called also al-Kunnash was a system of medicine in seven parts. He also translated it into Syriac, to give it wider usefulness. The information in Firdaws al-Hikmah has never entered common circulation in the West because it was not edited until the 20th century, when Mohammed Zubair Siddiqui assembled an edition using the five surviving partial manuscripts. There is still no English translation.  A German translation by Alfred Siggel of the chapters on Indian medicine was published in 1951.
