Oliver Kahl and Henrietta Sharp Cockrell present a facsimile edition of a newly discovered medieval medical text attributed to the famous physician Abū Bakr Muḥammad ibn Zakariyyāʾ al-Rāzī (Rhazes, d. 925 CE). This unique Arabic manuscript comprises a work in the health regimen genre titled “Book of the Crown” (Kitāb al-Iklīl). Copied in 1220 CE and bound parallel to the text (flip-bound), it is highly unusual, both in terms of physical appearance and topical choices. The edition is accompanied by an annotated English translation en regard, a detailed introduction including a codicological study, and bilingual indices.
