This Watts' publication on the Chapel by Mark Bills presents for the first time a comprehensive guide to the symbolism of the glorious Arts and Crafts patterns that cover its interior and exterior. Profusely illustrated with all the decorative details, the book reveals the richness of meaning that infuses the Chapel's imagery - imagery that is, according to Mary's own book on the subject, both 'exoteric and esoteric in its character, being in some instances so plain and simple... and in others so hidden and intricate'. To Mary, a symbol was a 'magic key' that 'unlocks a door into a world of an enchantment'. It is hoped that this guide will enhance both the understanding and enjoyment of this wonderful building.
