Najm al-Dīn Abū al-Futūḥ Aḥmad ibn Muḥammad ibn al-Sarī, called Ibn al-Ṣalāḥ (died 1154), was a scholar who wrote critical commentaries on logic and mathematics. In total at least 17 works by Ibn al-Ṣalāh are extant today.[1]
Ibn al-Ṣalāḥ was born either at Samsat or Hamadan. He trained as a physician.[2] He served as court physician to Ilghazi (r. 1107–1122), the Artuqid ruler of Mardin.[3] He ended his life in Damascus. He is known for his critique of errors in the transmission of Ptolemy's Almagest, for which he examined one Syriac and four Arabic manuscripts.[2] He wrote a Treatise on Projection, commentaries on Galen and eight tracts on Euclid's Elements.[3]
