RT Article T1 “Abominable Mixtures”: The Liber vaccae in the Medieval West, or The Dangers and Attractions of Natural Magic JF Traditio VO 64 SP 229 OP 277 A1 Lugt, Maaike Van Der LA English YR 2009 UL https://ixtheo.de/Record/1798040468 AB In his magnum opus on the history of magic, Lynn Thorndike devoted a few pioneering pages to the Liber vaccae or Book of the Cow. He identified and described several of the manuscripts of this singular Arabic compilation of magical experiments, pointed out the many different titles under which it was known in the medieval West, and discussed its false attribution to Plato, Galen, and Hunayn ibn Ishâq. By contrast, given his habit of paraphrasing the texts he examined at great length, Thorndike's account of the content of the work is uncharacteristically patchy. He hastily referred to “elaborate experiments in unseemly generation and obstetrics,” the aim of which was “to make a rational animal from a cow or ape or other beast, or to make bees.” In his opinion, the experiments of the Liber vaccae were, in fact, “unmentionable,” and “hardly such as can be described in detail in English translation.” DO 10.1017/S0362152900002312
