Interesting to think that some of these stones may have stayed behind to represent the knowledge of the group that stayed behind. If the stones can be thought of as “books”, some of the extra empty ones were relocated with the knowledge of other books moved into them in new contexts.
Equally possible, the local Waun Mawn peoples may have knowledge that they traded to a larger site for maintenance and storage to be distributed to other sites?
Equally, Waun Mawn did not become the core of a monument complex of the kind known around other great stone circles, such as the Ring of Brodgar, Aveburyand Stonehenge. Its development as a major centre in the earlier Neolithic (see Figure 1)appears to have been curtailed by early dismantling. Although the region was probably not entirely evacuated—the four remaining stones at Waun Mawn possibly symbolise the identities of those groups who remained local—it may have been extensively depopulated. Only further research into settlement and land-use employing other lines of evidence, such as palynology, will provide answers. 1
