CATALOGUE NOTE Mahmud al-Jaghmini (died circa 618 AH/1221AD) composed multiple scientific works in Arabic in the late 12th and early 13th centuries under the auspices of the Khwarazmshahs in Central Asia. Two of his compositions became popular textbooks: an introduction to Ptolemaic theoretical astronomy (al-Mulakhkha f? ilm al-hay’ah al-basita) and his medical treatise al-Qanunca, an abridgement of Ibn Sina’s compendium al-Q?n?n f? al-tibb. The impact and longevity of their influence is evidenced by the plethora of extant copies of the originals and their many commentaries and translations, which continued to be studied extensively for centuries and disseminated widely throughout the Islamic world and South Asia.
