On 4 July 925, twelve-year-old Shabbethai Donnolo was taken prisoner by Arab forces commanded by the Fatimid amir Abu Ahmad Ja'far ibn 'Ubaid. While his relatives were transported to Palermo and North Africa, Donnolo was ransomed by family members in Otranto. This childhood trauma preceded his development into an influential physician and scholar in southern Italy.
Medical Practice and Scholarship
Donnolo established a reputation as a physician and pharmacologist, training under a teacher from Baghdad. His approach combined knowledge from Greek, Arab, Babylonian, and Indian scientific traditions. Records indicate he practiced medicine in Rossano, as noted in the biography of the abbot Nilus the Younger, and eventually served as a physician at the Byzantine court. His surviving medical work, the Sefer ha-Yaqar, functions as an antidotarium containing practical instructions for preparing medicinal roots.
