a Spanish rabbi, a native of the province of Aragon, lived in the early half of the 15th century. He was one of the sixteen Jews who took part in the controversy in the presence of pope Benedict XIII. He wrote and spoke Latin with elegance. A part of his argumentation is found in the Historia Judceorum of Gentius (p. 231). We also have from him a book entitled Message (Constantinople, 1517). See Hoefer, Nouv. Biog. Generale, s.v.
