5040/1280, Rabbeinu Yitzchak of Coeurville, mechaber of the SeMak (Sefer Mitzvos Hakatan)
Rabbeinu Yitzchak was the son of Rabbeinu Yosef. He was among the last of Baalei Tosafos. He was the talmid and later the son-in-law of Rabbeinu Yechiel of Paris, and a brother-in-law of Rabbeinu Mordechai.
He also learned under Rabbeinu Shmuel of Aubra, one of the French Baalei Tosafos and a close associate of Rabbeinu Peretz and Rabbeinu Yonah of Girondi.
Rabbeinu Yitzchak is best known for his work Sefer Mitzvos Katan, also known by its acronym SeMaK, a compilation and concise listing of the 613 mitzvos. It is based on the concept of the Sefer Mitzvos Gadol, SeMaG, of Rabbeinu Moshe of Coucy, but does not delve into the discussions behind the decisions.
The sefer is divided into seven “pillars” for the days of the week, which he calls Amudei Golah. In it he explains which mitzvos are applicable in these days, hence the name Golah (meaning applicable even in galus).
He dispatched the Sefer Mitzvos Katan at his own expense to Jewish communities in Western Europe so that they might copy its contents as a record of the mitzvos they were obligated to fulfill.
Many of the Rishonim, and later the Acharonim, wrote notes on the SeMak.
Rabbeinu Yitzchak was niftar on 28 Iyar, 5040/1280.
