 This is certainly what happens in Mycenaean art. The concentric circles of 

 later patterns are quite clearly derived from the spirals of earlier patterns, 

 and there are some interesting- transitional forms: this is a commonplace of 

 Aegean art-history, and need not here be enlarged upon or illustrated. But 

 can we now be sure that i lie spirals of New Grange are necessarily connected 

 genealogically with the circles 1' wth? The former may. as has been
