This chapter focuses on the results for headstone shape as the first geometric
property examined. Headstone shape varies according to location, but the pattern of
diffusion becomes more difficult to identify at a larger scale. The results indicate that
the expected decline in the variation of headstone shapes is not apparent within all
sites. Despite this, there are more popular shapes used in England and Scotland across
time.
