Asās al-maqālāt fī qamʿ al-jahālāt: A Hitherto Unknown Zaydī Heresiography from Northern Iran

This paper revolves around a hitherto unknown heresiography from northern Iran, Asās al-maqālāt fī qamʿ al-jahālāt, which is preserved in a unique manuscript contained in a majmūʿa (Ms. Tehran, Majlis 10727). In the introduction, we describe the multitext codex, one of the few extant codices testifying to the continuous presence of Zaydism in northern Iran beyond the sixth/twelfth century. Additionally, we discuss two alternative tentative identifications of the author of Asās al-maqālāt, Abū Muḍar Shurayḥ b. al-Muʾayyad al-Muʾayyadī al-Shurayḥī and Muḥammad b. al-Ḥasan al-Shurayḥī al-Muʾayyadī. While the latter is entirely unknown, Abū Muḍar is renowned for his Asrār al-Ziyādāt, and we attempt to situate him more precisely in the chronology of Zaydī scholarship. Finally, we provide an editio princeps of Asās al-maqālāt fī qamʿ al-jahālāt.
