The paper focuses on the enigmatic thirteenth-century figure of R. Isaac of Rus’. A case study in the reconstruction of early East European Jewish history, it tests an integrative approach that brings together different types of evidence and disciplinary methods, while involving some new or neglected sources. Also examined are connections between Rabbi Isaac’s esoteric teachings and those of Ḥasidei Ashkenaz and related themes in contemporary and subsequent rabbinic literature.
