The superficial similarity in form of prehistoric standing stones and early medieval western British inscribed stones has sometimes led to the suggestion that the medieval stones were reusing the earlier monuments. In this paper this suggestion is cr... Read More about The Reuse of Prehistoric Standing Stones in Western Britain? A Critical Consideration of an Aspect of Early Medieval Monument Reuse.
