BOOK DESCRIPTIONAn interesting and unusual work on a little-explored field of study. By means of the iconographic evidence, the author aims to provide a counterbalance to the traditional studies of medieval welsh piety with their heavy emphasis on poetic material. Thereare interesting and suggestive divergences between the ideas communicated by literary evidence and those suggested by the surviving visual culture. In considering the importance of visual imagery as evidence for religious beliefs, the part played by imagery in the formation and reinforcement of a distinctive spirituality is not ignored. The work concentrates on surviving images from the 'golden century', but patterns of destruction and preservation are identified, including rare works lost through poverty and neglect.
