Sometimes known by the acronym Ri Migash, Joseph ben Meir HaLevi Ibn Migash (sometimes, Megas) was a rabbi, legal decisor, and rosh yeshiva (head of the academy) in Lucena. He studied under the renowned talmudist Isaac Alfasi (Rif) before being appointed rosh yeshiva after the latter’s death. His most famous pupil was Maimon, the father of Rambam. Although Rambam in his writings seems to indicate that he was himself a pupil of Ri, this is unlikely given that he was all of six years old when Ibn Migash died. It is more likely that Rambam meant that he learned Ibn Migash's teachings from his own father. Ibn Migash wrote over 200 responsa in Judeo-Arabic that were later translated into Hebrew, and a commentary on the Babylonian Talmud, of which only his writings on tractates Bava Batra and Shevuot are extant.
