De l’achat des esclaves : entre examen médical et physiognomie. Le chapitre 46 du Kitāb ad- dalā’il d’Ibn Bahlūl (Xe s.)

The use of physiognomy for the purchase of slaves is attested in several treatises from the classical and post-classical periods of the Arab-Islamic world. This article presents how medicine and physiognomy are related to the purchase of slaves and the perception of this relationship in the work of the Nestorian Ibn Bahlūl (10th c.). An annotated translation of the 46th chapter of the Kitāb al-dalāʾil is provided at the end of the article.
