Think 'John Michell' -ish.
"John Frederick Carden Michell (9 February 1933 – 24 April 2009)[1][2] was an English writer whose key sources of inspiration were Plato and Charles Fort. His 1969 volume The View Over Atlantis has been described as probably the most influential book in the history of the hippy/underground movement and one that had far-reaching effects on the study of strange phenomena: it "put ley lines on the map, re-enchanted the British landscape and made Glastonbury the capital of the New Age." [3]

In some 40-odd titles over five decades he examined, often in pioneering style, such topics as sacred geometry, earth mysteries, geomancy, gematria, archaeoastronomy, metrology, euphonics, simulacra and sacred sites, as well as Fortean phenomena."


I don't think I'm going to like your theory. ;)

I've had a look at the pictures of Trevethy Quoit, closely, and this isn't the best example to illustrate my theory with. The aperture, in the capstone, is so irregular as to make deriving a consistent measurement, for the length and breadth, very difficult. There are other holed stones which are better examples but they are not securely dated. They often get identified as some kind of gatepost.

The theory is that the 4:3 ratio of viewing a scene was invented/discovered by prehistoric people. We think of sun or moon light coming through the stone, illuminating whatever is beneath, but it must also be possible, with the correct posture and monument accoutrements, to use the aperture to watch the sky, or a segment of it, go by. Which is what we do with windows, in walls and on our desktops.
