Julian Cope presents Head Heritage

No, but one may argue that as there are now religous ceremonies taking place at Stonehenge - particularly at the four corners of the farming year - then these are the half-forgotten remnants of similar transactions in prehistory. Never mind that there is an unrecorded gap - it's just what's happening now. Yet there is very little evidence for contemporary flour milling at Stonehenge and, if it had been occurring in the manner you suggest (which is downright impossible because of the rough and ready stonework), then one might expect the grave goods from the surrounding burials to, in some way, reflect this. Sadly the Industrial Revolution began in the 18th C, or thereabouts (I know you can argue that Chinese potters were the first and Wedgewood just copied that model). What your theory imputes is that the Industrial Revolution started in the Neolithic and was then forgotten about - this is palpable nonsense and has no supporting evidence whatsoever.
