The code was concealed in symbols, hidden in the art, artefacts and architecture of the medieval world. Although this “hidden symbolism” can be deciphered with the help of certain keys, there will always be an intuitive element to the understanding of the coded messages. This book is an inspiration to examine the artefacts, paintings and architecture, looking for the hidden codes – to experience the mystical sensation of discovering the secret messages meant for us and our descendants as much as for the artists’ contemporaries.
