Abraham Ibn Ezra Latinus on nativities: a parallel Latin-English critical edition of 'Liber Nativitatum' and 'Liber Abraham Iudei de Nativitatibus'

Abraham Ibn Ezra was “reborn” in the Latin West in the last decades of the thirteenth century thanks to a plethora of authored and anonymous Latin translations of his astrological writings. The present volume offers the first critical edition, accompanied by an English translation, a commentary, and an introductory study, of Liber nativitatum (Book of Nativities) and Liber Abraham Iudei de nativitatibus (Book on Nativities by Abraham the Jew), two astrological treatises in Latin that were written by Abraham Ibn Ezra or attributed to him, and whose Hebrew source-text or archetype has not survived. The first is undoubtedly an anonymous Latin translation of the second version of Ibn Ezra’s Sefer ha-moladot (Book of Nativities), whose Hebrew source text is otherwise lost. The second is the most mysterious specimen among the Latin works attributed to Ibn Ezra that have no extant Hebrew counterpart. The present volume shows not only that the Liber Abraham Iudei de nativitatibus underwent a significant metamorphosis over time and was transmitted in four significantly different versions, but also that its date of composition is not that previously accepted by modern scholarship.
