It may be his interpretation based on archaeological evidence George but it is nevertheless pure speculation that there was no set plan. Prof Atkinson viewed exactly the same thing but interpreted it differently. He claimed it was built in three main stages whilst JL claims 15 at least. That's fine and I'm easy with that, but the conclusion isn't IMO and nothing to do with thinking but the sheer undertaking of the task for it to be random. In the CH4 programme, Silbury: The Heart of the Hill that JL featured in, the claim was made that the hill took between 100 to 400 years to complete depending on how the evidence stacked up. It now comes down to 100 years but the building principles were still the same so the suggestion that it was continually built upon for what could have been up to 400 years as just a 'storytelling ritual' I find hard to swallow. But of course I'm speculating as well but feel more comfortable with my belief even though I may be just as way of the mark as I feel he is. We're not there yet I feel with the hill still keeping hold of its secrets and waiting for the next idea to come along. Love it!!
