White Island on the Ocean (cont.)Seven Landscape Mysteries of Bronze Age Britain, A Unified TheoryBy William Glyn-Jones

Now the long side is divided into two lengths, and the ratio of the shorter of these to the longer is the same as the ratio of the longer to the sum of the two. This is the Golden Ratio, in which, as with political systems where ma'at or eunomy is present - the effective running of the polis made up of individuals - as with such systems the relationship of the parts is found by factoring in the whole of which they are parts. It is a proportion that has repeatedly been found to be aesthetically pleasing, and it is still used widely today. Since it is this that makes the 2 by 1 rectangle so interesting to the Hermetic-Platonic artist and architect, I reasoned that I would expect to find something of significance at the Golden Section of the line in question. I had to now use a different name for the line. I couldn't call it the St Michael Line anymore; I wanted as far as possible to leave that line alone, allowing it its own existence whether as a new or old idea, and to treat this 2 by 1 line as a different entity. I toyed with long names like the Foundational Vitruvian Hypotenuse, but the Golden Diagonal will suffice. So I was after the Golden Section point along the Golden Diagonal.

Marking off the Golden Section of the long side of a 2 by 1 rectangle using the length of the diagonal minus the short side. Right: this same geometry in use in an Egyptian depiction of the Spirit Double of an Official standing in a 2 by 1 'False' Door, with the geometry superimposed. (Various researchers, such as, notably, Else Christie Evans in Geometry in Egyptian Art, have observed that the Golden Section is absolutely rife in Egyptian imagery.)

I had a map in front of me with the line marked along it. With a long ruler, I measured the full length, calculated the Golden Proportion of that, and then measured again to find that suitable spot for the Polis of Ma'at, for Eldorado, the City of Gold. Here was the first revelation. No matter how many times I measured it, the Golden Section of the 2 by 1 diagonal from West Point to East Point through Glastonbury Tor exactly pinpointed the most significant archaeological site in the whole of the Thames Valley, a complex of sites once including an enormous double henge with cursus. It was, of course, that Dorchester-on-Thames site that we have spoken of already.
