Yoel ben Shmuel Sirkes

Yoel Sirkes was a Polish rabbi, halachic scholar and Talmudic annotator. His best-known work, Bait Chadash, is one of the basic commentaries (together with R Yosef Karo's Beit Yosef) on R. Yaakov ben Asher's halachic code, the Arba'ah Turim. Hagahot Habach are his indispensable glosses on the text of the Talmud. The Taz was his son-in-law.
