The contents of this dense, multifaceted book, which spans the time period from Bede to the dawn of the Renaissance, cannot be summarized. It is a book that opens new avenues for adhering as closely as possible to the nature of medical treatment, the complexity of which is currently being rediscovered after decades of reductionistic physiological mechanicism that truncated the approach to ancient medicine. It is a book to be meditated upon more than simply read, almost a manifesto for a renewed history of medicine that desegments the field and opens it to the multiplicity that it always had but that historical dissection lost by anatomizing it according to sources, academic disciplines, and approaches.-Alain Touwaide, affiliated with the the Huntington Library, Art Collection, and Botanical Gardens in San Marino, California
