This book is a survey of the relationship between the two Celtic and Roman traditions in Merovingian Gaul, Lombard Italy, and the British Isles during the period of the Easter controversy. It looks at baptismal liturgy, the style of tonsure, and the correct dating of Easter.
An in depth exploration of the similarities and differences between Celtic and Roman Church practices focusing primarily on the conflicts over the formulations and the resulting tables for the dating of Easter. At times my eyes glazed over while in the nitty gritty detail. However! I am glad to know I have such details accessible to me on my bookshelf!
