Set of [3] parts, responsa and novellae on the Ramba”m and novellae on Talmudic topics by Rabbi Shlomo ben Rabbi Avraham HaKohen – Maharasha”ch – who was among the leading adjudicators of his generation. Important work printed by the author in his lifetime. (Y. Mehlman, Genuzot Sefarim, Perakim B’Toldot HaDefus B’Saloniki no. 40, 43). The first part was printed in Salonika 1586-1587, without a title page. Instead of a title page, the author wrote something of an introduction at the top of the first leaf, in which he writes about the progression of the book’s printing, and he even mentions the benefactors from the ‘Midrash Garush Castila’ (communities of exiles from Spain in Salonika) who assisted him. The year of print appears at the end of the introduction. The second part was printed in 1592, part in Venice and part in Salonika. The title page indicates that it was printed in Venice, but the author added another 29-page part, which he printed in Salonika. At the beginning of this additional part the author writes that he sent it to be printed in Venice, but in the meantime he continued to write responsa, despite his weakness, and those he is printing in his own city, Salonika. He adds: “and these two books … will be joined together.” The third part, printed in Salonika 1594-1595, again without a title page, and with an introduction in place of a title page with the year and place of printing at its conclusion. The author writes in the introduction about the earlier part he had printed and about its supplement, because he thought that due to his weakness he would not print any more. However, despite his illness, he did continue writing responsa, and is now printing them before passing away. After about 150 years, another part was printed, but not by the author. Ancient owners’ signatures and glosses in Oriental writing: “Yosef Nowey,” “Yitzchak Dayan,” “Avraham Levitan”? Rabbi Shlomo HaKohen of Salonika [c. 1520-1602], known by his initials: Maharasha”ch, was among the leading Spanish sages from the generation after Rabbi Yosef Karo, and one of the leading adjudicators of his generation. He served in the rabbinate of the Monastir community in the Macedonia region, and then as rabbi of the community of exiles of Castile in Salonika. He was friends with the Mahariva”l and Maharashda”m who were considered together to be the leading adjudicators of their generation, such that one of the sages in their generation expressed his opinion that the three adjudicators: Rabbi Shlomo HaKohen, Mahar”i ben Lev and Rabbi Shmuel di Modena are considered the pillars of instruction like the Ri”f, the Ro”sh and the Ramba”m in their generation. One of his famous rulings is with regards to not linking debt to changes in the the value of the currency. This ruling of his opposed that of his elder colleague, the Maharashda”m.
