"This volume, both readable and handsomely produced, includes a detailed historical treatment of the controversy, as well as a critical edition based on five manuscripts and diplomatic editions of each reconstructed manuscript, letters and other polemical writings that circulated during 921–922, and later sources from the following centuries. (...) This new treatment of the controversy is long overdue and very welcome." - Melonie Schmierer-Lee, in: Genizah Fragments, October 2019
