The early islamic physicians were familiar with the life of Hippocrates, and were aware of the fact that his biography was in part a legend. Also they knew that several persons lived who were called Hippocrates, and their works were compiled under one single name: Ibn an-Nadīm has conveyed a short treatise by Tabit ben-Qurra on "al-Buqratun" ("the (various persons called) Hippokrates"). Translations of some of Hippocrates's works must have existed before Hunayn ibn Ishaq started his translations, because the historian Al-Yaʾqūbī compiled a list of the works known to him in 872. Fortunately, his list also supplies a summary of the content, quotations, or even the entire text of the single works. The philosopher Al-Kindi wrote a book with the title "at-Tibb al-Buqrati" (The Medicine of Hippocrates), and his contemporary Hunayn ibn Ishāq then translated Galens commentary on Hippocrates. Rhazes is the first Arabic-writing physician who makes thorough use of Hippocrates's writings in order to set up his own medical system. Al-Tabari maintained that his compilation of hippocratic teachings ("al-Muʾālaḡāt al-buqrāṭīya") was a more appropriate summary. The work of Hippocrates was cited and commented on during the entire period of medieval islamic medicine.
