In this extensive study of the Christian mythology that animated Europe in the Middle Ages, author Philippe Walter reveals how these stories are based on ancient pagan rituals and myths with little or no connection to the Bible. Walter, a French Professor of medieval literature, concentrates mainly on his area of expertise, primarily Celtic and Gallic material, with many allusions to earlier Indo-European themes.
With a highly academic approach, it makes rather heavy reading at times, although it does undoubtedly provide a very well researched, accurate and convincing historical argument for its basic premise. The book conclusively explains how and why certain ancient pagan festivals that were related to the changing seasons, i.e. solar and lunar cycles, were transposed into a Christian context. Obvious examples are Easter and Christmas, which need no explanation for readers of this review.
