''Maharil's
best known work is Minhagei Maharil, also known as Sefer ha-Maharil
or simply the Minhagim (customs)
. It contains a detailed description of religious observances and rites, at home and in the synagogue, and thus provides an authoritative outline of the minhagim'' of the
German Jews. It also contains sermons and textual comments. It was compiled by Moelin's student,
Zalman of St. Goar, and was first published - with various additions - at
Sabbioneta, in 1556 and frequently thereafter. It had a great influence on the Jews of
Central Europe and was largely responsible for the importance attached to
minhag in these communities. This book is frequently quoted in the
codes and commentaries - including
Moshe Isserles who cites
Maharil frequently in the
Shulkhan Arukh - and has become a valuable source for
later scholars (Achronim). Another pupil of Moelin, Eleazer b. Jacob, collected some of Moelin's
responsa; these were published in
Venice in 1549. Many more of Moelin's
responsa remained in manuscript. These were collected and edited by Rabbi Yitzhak Satz, and, published in 1977 under the title
SHuT Maharil heChadashot ("New Responsa of Yaakov Molin"). Recently, the German
esoteric scholar Georg Dehn has argued that the MaHaRIL was also the author of
The Book of Abramelin, which he wrote under the pseudonym of Abraham von Worms. However, this is disputed.
Text of Minhagei Maharil Unlike traditional books, the text of
Minhagei Maharil was never fixed. In his critical edition of Minhagei Maharil, Shlomo Shpitzer surveyed 22 manuscripts of the work and noted that "The only thing common between them was that no one text was like the other." As such, there is great importance to every early version of the work. In 1989,
Machon Yerushalayim published a critical edition of the work, edited by Shlomo Shpitzer. In 2024,
Wieder Press published a facsimile edition of the RSL Ginzburg 979 manuscript which wasn't available to Shpitzer when he did his work. ==Notes==
