Sefer Mitzvot Gadol
Rav Moshe of Coucy lived in France in the early 13th century. This work, an acronym for Sefer Mitzvot Gadol, was a halachic text that defined and explained the 613 commandments and their halachic implications. It draws heavily on the Mishne Torah, and it is referenced in the Ein Mishpat, which appears on every page of the Talmud. He also wrote a commentary on the Chumash and had a hand in authoring some of the Tosafot on the Talmud. His teacher was Rav Yehuda HaChassid.
