Ali ibn Abbas al-Majusi Ahvazi Arjani

Ali ibn Abbas al-Majusi Ahvazi Arjani, known in Europe by his latinized name, Haly Abbas or Ali Abas, was born in Ahvaz or Arjan (Behbahan), located in the Southwestern Iran, in 930 AD. Al-Majusi is best known for his Kitab Kamil as-Sinaa at-Tibbiyya (“Complete Book of the Medical Art”, in Latin “Liber Regius”). The book was not only entirely based on the work of others, but also al-Majusi included his own observations. He dedicated this book to King Adhud al-Dawlah Dilami (died in 983 AD). Al-Majusi served as court physician and worked in the Adhudi hospital in Baghdad. The Maliki is divided into 20 discourses, of which the first ten deal with theory and the second ten with the practice of medicine, such as surgery. It also contains many ethical parameters. Accordingly, it was the textbook on medicine for several centuries after the book was translated into Latin, and it was widely used not only in Persia and Arabic countries, but also in many parts of Europe. He died in Baghadad or Shiraz in 994 AD.
