This manuscript is written on Arabic paper. It was completed in Damascus in July 1184 by Ibrāhīm ibn Naṣr ibn Ibrāhīm ibn Muḥammad ibn al-Ḥasan ibn Munīr al-Kīlānī, who made the copy for his own personal use.
Some of Galen’s works were translated into Arabic by Ḥunayn ibn Isḥāq al-‘Ibādī, and this manuscript preserves three of them: On Crises, On Critical Days, and On the Differences of Fevers. Covering pathology, prognosis, and therapy, these texts mainly discuss the patterns of various diseases, sometimes with reference to astrology.
Medical works by or attributed to the physician Galen (129-c. 200 CE) were an important source of information throughout the Middle Ages both in Europe and in the Middle East.
