Al-Hasan ibn Musa al-Nawbakhti, Commentary on Aristotle "e;De generatione et corruptione"e;

This book contains a new edition and English translation of the oldest commentary on Aristotle written in Arabic and preserved to this day, together with an extensive commentary. It is a compendium on the treatise De generatione et corruptione, written by the Imamite theologian and heresiographer Hasan b. Musa al-Nawbakhti (fl. ca. 900). To this day, apart from the title of more than forty works and numerous fragments-taken mainly from his magnum opus, the Book of the Doctrines and Religions (Kitab al-ara' wa-al-diyanat)-only a single treatise of his, the Book of Shi'i Sects (Kitab firaq al-shi'a), was known to us. The text sheds new light in several ways: firstly, on the the Arabic philosophical tradition, since it was composed during the obscure period between al-Kindi and al-Farabi (roughly, the 2nd half of the 9th c.); secondly, on the Greek tradition, since the author makes extensive use of Alexander's lost commentary on De generatione; thirdly, on the formative period of shi'ism, since it helps us to reconstruct how the author borrowed from the Aristotelian tradition the tools necessary to build up a new anthropology compatible with the doctrine of the Occultation which he inaugurated at the time.
