This book presents the hypothesis that the Bayeux tapestry, long believed to have been made in England, came from the Loire valley in France, from the abbey of St. Florent of Saumur. This is based on a number of different kinds of evidence, the most important of which is signs of a St. Florent/Breton influence in the portrayal of the Breton campaign in the tapestry, about a tenth of the whole.
