This is a large medical compendium written in 782 AH/1380 CE in
Ephesus for ’Īsá ibn Muḥammad, the Sultan of Āyidīn. The
author was a Turkish physician who spent most of his working life
in Cairo where he became ra’is al-aṭibbā’ (Chief of
Physicians) and associated with the Bīmāristān Manṣūrī. In
this treatise he speaks of the knowledge he gained working in
hospitals and states that he herein reveals medical information
formerly kept secret, as well as acknowledging his debt to his
master, Jamāl al-Dīn known as Ibn al-Sūlkī. The copy was made
by Ismā’īl ibn Turkī al-Manshalīlī and is undated, but the
nature of the paper, ink, script and illumination suggests a date
of the late fifteenth-century.
