Isaac al-Kanzī

Isaac ben Samuel ha-Sephardi al-Kanzī was a leading rabbinic scholar in twelfth-century Fustāt (Old Cairo). Isaac wrote responsa, a short talmudic commentary, a commentary on the Prophets, and liturgical poetry. Several court documents preserve his name as well, as he was an active member of the local rabbinic court. Isaac apparently sided with David ben Daniel in a bitter battle over Jewish leadership in the late eleventh century, and he later held appointments from the eleventh-century nagid Mevorakh ben Se‘adya and his son Moses.
