1911 Encyclopædia Britannica/Isserles, Moses Ben Israel
ISSERLES, MOSES BEN ISRAEL (c. 1520–1572), known as Remā, 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 Shulḥan Aruch of Joseph Qaro (Caro)(q.v.). His chief halakhic (legal) works were Darke Moshē and Mappāh. Qaro, a Sephardic (Spanish) Jew, in his Code neglected Ashkenazic (German) customs. These deficiencies Isserles supplied, and the notes of Remā are now included in all editions of Qaro’s Code.
