"You stated gaining knowledge about Silbury, & it has been customary to regard the turf stack seperate. It becomes even more important to keep the two apart when considering what happens next as <b>the information at the centre of Silbury isn't about the hill itself but the period in which it was built.</b> "
Are these not one and the same? how can the neolithic ground surface not be about Silbury? It was covered when Silbury was built and can tell us what was going on then - which surely relates to its original construction?
