Wouldn't say that eveything Michael Dames writes "Must be right..." nor would I say that everything he writes is not right.
I've a lot of respect for Dames; I've head him speak on seveal occasions and have read, with the exception of his latest book (Merlin and Wales) practically everything he's written. He actually reminds me a little of Stukeley - a free spirit, endearingly eccentric, and not giving too much of a damn what others think; I like that, in fact I'll take that every time over the witless witteres who are very good at quoting others but don't have a single original idea in their head.
To the point, BigSweetie asks whether Silbury has (or had) a spiral path leading to the top. I'm pretty sure Dames mentions this somewhere but haven't had time to check out the book/page reference yet. Bigsweetie also mentions in his last post the Greek ledgend surrounding the Hyperboreans. Not sure if I want to get drawn into that one but for further info please see Ledgendary Landscapes by J D Wakefield (ISBN 09536301-0-2).
Guess the whole idea of a winding path to the top of Silbury rests on one question - was the top of Silbury originally conceived as a flat area? If it was it was conceived so for a reason, and getting to the top for that reason would have necessitated a winding path (you could of course have gone straight up one of the sides but I imagine that's hard work and not very dignified ;-).
