Nahmanides (nähmänˈĭdēz) [key], 1194–c.1270, Jewish scholar, exegete, and kabbalist, b. Spain. He wrote commentaries on the Hebrew Bible and the Talmud. A mystic, he rejected part of Maimonides' philosophy but recognized his greatness. He wrote an account of his disputation with the anti-Jewish agitator Pablo Christiani, which took place in the presence of King James I of Aragón. In 1267, Nahmanides settled in Palestine. He is also called Rabbi Moses Ben Nahman (abbreviated to Ramban).
