The proposed paper will examine two fragments of Ashkenazi provenance: one discovered in Cheb, Czech Republic, and the second one in the Augustinian monastery of St. Florian, Austria. The paper will argue that the two fragments represent two stages of Ashkenazi appropriation of medical lore: the Cheb fragment is close in terminology and intellectual approach to the early medieval texts included in the “Book of Remedies” attributed to Asaf, whereas the second text is a fragement from an Arabic-to-Hebrew translation of Isaac Israeli’s Book of Urines.
