The book contains the critical edition and the study of an early medieval recipe book in which elements of quadruped animals are used for both pharmacological and magical purposes. Its main source is the Liber medicine ex animalibus by Sextus Placitus, although a third of the recipes come from other sources. In addiction to being of considerable linguistic, philological and anthropological interest, the work also demonstrates the transmission and the reception of ancient and late-antiquarian medical knowledge during the Middle Ages.
