Amaroth Tehoroth [Kabbalah]. With commentary “Yad Yehudah” by R. Judah Leib ben Shimon.

Part One of Amaroth Tehoroth, a compendium of five kabbalistic treatises by R. Menachem Azariah (RM”A) of Fano: Ma’amar Hikkur Din, Ma’amar Em Kol Hai, Ma’amar ha-Middoth, Ma’amar Olam Katan, and Ma’amar ha-Ittim. Today, this work is generally known by the title Asarah Ma’amaroth (“Ten Treatises” - although the other five treatises are missing). There are other commentaries on RM”A’s work, but Yad Yehudah remains the standard commentary. R. Menachem Azariah (1548-1620), of a well-to-do banking family in Bologna, Italy, was first a follower of the Cordoveran system of kabbalah but afterward, under the influence of an elusive figure, R. Israel Sarug, switched his allegiance to the Lurianic school. The propagation of Safedian kabbalah in Europe was largely due to his prolific efforts.
