Nicholas Herman, Curator of Manuscripts at the University of Pennsylvania Library, offers a video orientation to Penn Library’s LJS 392, Taḥrīr al-majisti, by Ṭūsī, Naṣīr al-Dīn Muḥammad ibn Muḥammad (1201-1274). This manuscript was written around A.H. 813 (1411), in Arabic, and it is a 13th-century recension of Ptolemy’s Almagest with the early 14th-century commentary of the Iranian scholar and astronomer Niẓām al-Dīn al-Nīsābūrī.
