Composing Arugat ha-Bosem: How Piyyut Commentary Became Associated with Ḥasidei Ashkenaz

Abstract

AbstractBased on Ivan Marcus’s concept of “open book” and considerations on medieval Ashkenazic concepts of authorship, the present article inquires into the circumstances surrounding the production of SeferArugat ha-Bosem, a collection of piyyut commentaries written or compiled by the thirteenth-century scholar Abraham b. Azriel. Unlike all other piyyut commentators, Abraham ben Azriel inscribed his name into his commentary and claims to supersede previous commentaries, asserting authorship and authority. Based on the two different versions preserved in MS Vatican 301 and MS Merzbacher 95 (Frankfurt fol. 16), already in 1939 Ephraim E. Urbach suggested that Abraham b. Azriel might have written more than one edition of his piyyut commentaries. The present reevaluation considers recent scholarship on concepts of authorship and “open genre” as well as new research into piyyut commentary. To facilitate a comparison with Marcus’s definition of “open book,” this article also explores the arrangement and rearrangement of small blocks of texts within a work.
