Isaac Ben Samuel - Tosafot

Tosafot

Isaac's tosafot completed the commentary of Rashi on the Talmud (Romm included in his edition of the Talmud Isaac ben Samuel's tosafot on Ḳiddushin). He also compiled and edited with great erudition all the preceding explanations to Rashi's commentary. His first collection was entitled Tosefot Yeshanim, which, however, was afterward revised and developed. He is quoted on almost every page of the Tosafot, and in various works, especially in the Sefer ha-Terumah of his pupil Baruch ben Isaac of Worms, and in the Or Zaṙua of Isaac ben Moses.

Isaac is mentioned as a Biblical commentator by Judah ben Eliezer (Minḥat Yehudah, p. 8b), who quotes also a work of Isaac's entitled Yalḳuṭe Midrash (ib. p. 22a); by Isaac ha-Levi; by Hezekiah ben Manoah in his Ḥazzeḳuni; and in two other commentaries (see Kerem Ḥemed, vii. 68). Isaac b. Samuel is supposed to be the author also of several liturgical poems, of a piyyuṭ to the Hafṭarah (Landshuth, Ammude ha-'Abodah, p. 108), and of a piyyuṭ for Purim (Maḥzor Vitry, No. 255; comp. Luzzatto in Berliner's Magazin, v. 27, Hebr. part). The authorship of these piyyuṭim may, however, belong to the liturgical writer Isaac ben Samuel of Narbonne.
