Sha’arei Dura

Edited and corrected by R. Yitzchak b. Samuel Alchakim who added his own laws of Chalah and Candlelighting as well as an introduction and an index. This edition is different form both the previous and later editions. It was apparently published from a different manuscript and contains important variances both in the text, notes and in the names of the scholars cited. f. 47b states that the Author wrote the laws of menstruation at the request of his wife. This statement does not appear in other editions. R. Isaac of Duran (second half of 13th century) was a preeminent German halachic authority. His Sha'arei Dura is one of the most important Codes concerning dietary and menstrual laws. It is based upon the traditions of both Germany and France and became the basis for halacha in these particular areas
