He quotes a Mr. Cosworth of York re the Sun's shadow..."it is remarkable that the daily gauge of the shadows of both the Great Pyramid and Silbury is almost exactly four feet". What the hell does that mean?

Well just type gnomon/Silbury Hill, and you come up with H.G.Wells and The Secrets of the Heart..... I expect with egyptology at that time seeing Silbury as a gnomon was fashionable. As for the four feet would that be something to do with the sun overhead and post?
