Najīb al-Dīn al-Samarqandīʼs (d. 619 A.H. / 1222 C.E.) Book on Foods and Drinks (Kitāb al-Aghdhiya wa-l-ashriba) is a comprehensive encyclopedia on nutritional medicine containing information on more than 500 different food items, drinks and aromatic substances. With regard to 53 known manuscripts of the work, it is likely that it is among the most widespread pre-modern Arabic books on the science of nutrition. In Nahrungsmittel in der arabischen Medizin, Juliane Müller presents a critical edition of the Kitāb al-Aghdhiya wa-l-ashriba by taking into consideration almost all of its known manuscripts, along with a German translation of the text. Chapters on the textual and cultural history of this work compare al-Samarqandīʼs food encyclopedia to other Arabic texts on nutritional science and discover the sources and reception history of the Kitāb al-Aghdhiya wa-l-ashriba. Al-Samarqandīʼs food encyclopedia can be considered as the last major Arabic monograph on nutrition in the Islamic East.
