ISSERLES, MOSES BEN ISRAEL (c. known as REMA, was born at Cracow and died there in 1572. He wrote commentaries on the Zohar, the "Bible of the Kabbalists," but is best known as the critic and expander of the Shullian Aruch of Joseph Qaro (Caro) (q.v.). His chief halakhic (legal) works were Darke Moshe and Mappah. Qaro, a Sephardic (Spanish)
Jew, in his Code neglected Ashkenazic (German) customs. These deficiencies Isserles supplied, and the notes of Rema are now included in all editions of Qaro's Code.
