Much of early medieval Celtic and Anglo-Saxon art is based on the display of motifs key, interlacing, spiral and zoomorphic in well-defined panels in simple and complex arrays. A study of the arrangement of the panels and the fine detail of the motifs indicates that the artists relied on geometric methods and principles first used by Egyptians and Greeks. This book reflects Derek Hull's life-long interest in interpreting the exciting and exotic patterns revealed by scientific studies using light and electron microscopes. His interest in Celtic and Anglo-Saxon art started with a casual observation of an interlacing pattern on an early medieval stone cross set in a churchyard. There followed many years of exploration of art in metal, stone and vellum from all parts of the British Isles and Ireland, resulting in some fascinating discoveries. "Celtic and Anglo-Saxon Art" reveals new and intriguing facets of these works that add to our appreciation of the beauty of the art and the skills of the artists.
