One of the Spanish Muslim authors that could not be identified until now is Muḥammad b. Aḥmad b. Abī l-‛Āṣ al-Andalusī, to whom two short medical treatises are attributed. A study of the preserved manuscripts of both works, as well as the revision of some sources and recently published studies, will allow us to identify this author as the Granadan Morisco Muḥammad b. Abī l-‛Āṣī, a physician that in the first half of the 17th century left the Iberian Peninsula to (...) reside in Istanbul, and afterwards in Cairo, where his trace is lost in the year 1637. In this article, we will expose all the available biographical data about this person, and we will make a brief analysis of his two treatises. (shrink)
