This book is a new survey of the Celtic and Roman traditions in Merovingian Gaul, Lombard Italy, and the British Isles from 590-768. In it Corning argues that the main areas of conflict between the two traditions during this period were the Easter controversy and by extension the style of tonsure. Corning?s work serves as a valuable case study of the ways in which the early medieval Church attempted to reach consensus on divisive issues.
