Abraham ben David Caslari was a Catalan-Jewish physician. He lived at Besalú, Catalonia, in the first half of the fourteenth century. Caslari was considered one of the most skillful physicians of his time. He was the teacher of Moses Narboni of Perpignan, and one of the ten notables to whom, in 1323, Kalonymus ben Kalonymus of Arles addressed his treatise on morals, entitled, Eben Bochan (Touchstone).

Works

Abraham was the author of the following medical works, still extant in manuscript: He is also said to have translated into Latin the Antidotarium of Razi. The Book of Foods, written by Isaac Israeli the Elder, is falsely ascribed to Caslari. Profiat Duran Efodi of Perpignan, called in Hebrew "Isaac b. Moses ha-Levi," borrowed from Caslari the astronomic note which he cites in his commentary on the Moreh Nebukim of Maimonides. Caslari is also mentioned by Nissim Gerondi (Responsa, No. 33).
