Isaac ben Judah of Mainz

ISAAC BEN JUDAH OF MAINZ

ISAAC BEN JUDAH OF MAINZ (11th century), German scholar; teacher of *Rashi. Practically no biographical details are known of him or his family. The description given by J.N. Epstein (see bibliography) of the characteristics of the yeshivah of Mainz during the period that Isaac was its head, and the manner in which it differed from the contemporary yeshivah of Worms, has been rejected by Aptowitzer (see bibliography). Isaac was head of the famous yeshivah in Mainz founded by his teacher *Gershom b. Judah, to whom he was apparently related, as he was to Rashi. He seems to have come from France (Zedekiah b. Abraham ha-Rofe, Shibbolei ha-Leket ed. by Buber (1886). 66 no. 93). He was also a pupil of *Eliezer ha-Gadol of Metz who was also one of the heads of the Mainz yeshivah. In addition to Rashi, he numbered Eliakim b. Meshullam among his distinguished pupils. Eliakim refers to him as Moreh Ẓedek ("the righteous teacher") whenever he mentions him in his commentary to Yoma and Rashi uses the same title on Yoma 16b and in his responsa. According to Abraham Epstein, the commentary attributed to Rabbenu Gershom in the Romm (Vilna) editions of the Talmud to the tractates Menaḥot, Bekhorot, Arakhin, Temurah, Keritot, Me'ilah, Tamid, Ḥullin, Ta'anit, and Bava Batra was compiled in Isaac's bet midrash. Eight of his responsa are included in the Teshuvot Ḥakhmei Ẓarefat ve-Loter (1881), and in the introduction to this work J. Mueller gives a list of 17 of his responsa and novellae which are scattered throughout the literature. I. Elfenbein's edition of Rashi's responsa (1943) contains 38 of Isaac's, mainly directed to Rashi.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
