PERAḤYAH BEN NISSIM

PERAḤYAH BEN NISSIM (13th century), talmudist. No biographical details are known of him. In a document dated 1240 he is mentioned as being in Fostat, Egypt. In 1247 he wrote a commentary on the halakhot of Isaac *Alfasi and a manuscript of it in the tractate Shabbat, written in 1304, is preserved in the Bodleian Library.

Extracts from the work are cited in the novellae on Maimonides' Mishneh Torah, which are published at the beginning of the Ma'aseh Roke'ah of Mas'ud Roke'ah, and additional fragments were published by Assaf in Kirjath Sepher. Many of the quotations from Maimonides given by M.L. Sachs in his Ḥiddushei ha-Rambam la-Talmud (1963) were taken from this work. A section of the work on chapters five and six was published at the end of the Siyya'ta di-Shemayya (1970).
