In the traditions concerning Welsh stones, abundant personal attributes are accorded them, such as in nature belong only to animals. They were endowed with volition and with voice; they could travel from place to place without mortal aid; they would move uneasily when disturbed by human contact; they expanded and contracted at will; they clung to people who touched them with profane or guilty purpose; they possessed divers qualities which made them valuable to their possessors, such as the power of rendering them invisible, or of filling their pockets with gold.
