An Early Fragment of Ibn Jazlah's Tabulated Manual 'Taqwīm al-Abdān' from the Cairo Genizah

摘要

Ibn Jazlah was born and raised as a Christian in Karkh (Baghdad) and died in the year 1100. He acquired his medical education in Baghdad, worked at the 'Adudi hospital, and was appointed as a registrar and physician for the court at the 'Abbāsid capital and later became a court physician of Caliph al-Muqtadī. Ibn Jazlah wrote several books on various subjects, mainly on medicine. During the process of reconstructing the medical library of the medieval Jewish practitioners in Cairo, a Genizah fragment of a unique tabular medical book in Arabic was identified as Ibn Jazlah's tabulated manual 'Taqwīm al-abdān", which is most probably part of the earliest known copy of the text. A study of the T-S Ar.41.137 clearly shows that it was an uncompleted draft, and can therefore teach us how the medieval copier worked. The image of the fragment is presented here, as well as its transliteration, translation and analysis.
