This essay offers a new examination of medical knowledge in Merovingian Gaul (c. 500–c.750), the ways that it became part of non-specialized learning, and its continuities with Carolingian medicine. In most histories of medicine, the Merovingian world is portrayed as providing a hostile environment for medicine due to the Christianization of knowledge. A significant problem, however, is that there has been no study of what medicine was known or how it was treated since 1937, and even that study can now be seen to be built on false premises. The first part of the present paper offers a new conspectus of Merovingian medical knowledge based on the earliest manuscripts and argues that this new overview changes where we can see continuities in content and practice with Carolingian medicine. The second part builds on this to explore the intersections between religious and secular study, and how medicine fitted within a generalist rather than specialist education. The final section looks at how this learning complemented understandings of the miraculous and nature and in the process helped to deal with challenges from folk practice and the failures of medicine to offer effective aid during pandemics. It is concluded that medicine was in good health in the Merovingian period as it contributed useful ways to see natural order in Creation.
