The opening studies in this volume, on the revival of Galenic medicine in Continental Europe, provide the context for its focus - England in the 17th century. The author covers the discovery of the circulation of the blood, but it is the underlying components of health and medicine that form the subjects of this book. It deals, notably, with the strong link then perceived between health and the environment, perhaps even more present in people’s minds than today, with the relationship between medicine and religion, and with medical ethics. Further studies discuss the provision made for the sick poor, the popularisation of medicine, and the epistemological basis of learned or university based medicine. A theme throughout is the range of treatments available in the ’medical marketplace’ of the 17th century, from wise women to learned physicians.
