Firdous al-Hikmah is one of the oldest encyclopedias of Islamic medicine, based on Syriac translations of Greek sources (Hippocrates, Galen Dioscorides, and others). It is divided into 7 sections and 30 parts, with 360 chapters in total. The work was eclipsed by those of Rabban al-Tabari's more famous pupil, Muhammad ibn ZakarÄ«a Rāzi (Rhazes). After writing the work in Arabic Rabban a-Tabari also translated it into Syriac, to give it wider usefulness. However, the information in Firdous al-Hikmah 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.
