As a scholar of the languages of early Christianity, including Ethiopic and Syriac, Johannes Flemming felt a debt to the learned scholar of the seventeenth century, Job Leutholf (also Hiob Ludolf). Still cited as one of the essential pieces of Leutholf’s biography, this article is required reading for those interested in the life of this remarkable scholar. After sketching an outline of Leutholf’s life, Flemming then moves on to focus on his Ethiopic studies. Flemming concludes his articles with the correspondence between Leutholf and the abbot Gregorius who initially taught him the Ethiopic language.
