Abraham ben Isaac of Narbonne

Abraham ben Isaac of Narbonne sat at the head of both the talmudic academy and the court in Narbonne, where he taught figures who would come to lead the next generation of Provençal talmudists. Abraham ben David of Posquières (ca. 1125–ca. 1198) was his son-in-law and among his most important students. Abraham ben Isaac wrote a legal code called the Book of the Cluster (Sefer ha-eshkol) and composed talmudic commentaries, the majority of which survive only in quotations by later scholars. He served as one of the primary vehicles for the transmission of the Spanish halakhic tradition into Provence, and his generation inaugurated talmudic learning in that region.
