John Neal is Britain's great metrologer who, alongside John Michell, brought about a resolution of the ancient system underlying Historical Metrology, a subject plagued by misunderstood irregularies and peculiar interrelationships between different historical feet, the latter often involving the low numerical ratios, such five to six. Neal saw that the northern and southern variations of the same historical measures of 176/175 was part of a larger grid employing also the lesser ratio of 441/440 (the ratio of the polar radius to the mean earth radius), which creates an array of microvariation many of which being historically attested and each having multiple uses as geometrical and geodetic ratios such as in quadrature and the length of latitudinal degrees, for example. His first book in 2000 (All Done With Mirrors) was massive in scope and challenging to digest: as John says, he reads metrology with a calculator in his hand - suggesting one has to do calculations to verify and hence understand. John's work includes many essays and pamphlets and these and some new work is currently being published in three volumes (Ancient Metrology Series) of which two are now available. Here is an impromptu conversation with John taken at Stonehenge at Solstice:
This book builds a narrative for a prehistoric megalithic science whose achievements are now largely forgotten. Starting in the 5th millennium BC, at Carnac (Brittany, France), it is clear that an original metrology and type of geometry was developed in order to understand astronomical time periods in a way quite unfamiliar to present day science. After astronomical works, interpreted as leading to the form of monuments, megalithic science moved to understanding the shape and size of the earth using the same techniques and in order to complete this work, some of its best astronomers moved to Egypt so that by 2500-2600 BC, two distinct yet different monuments were constructed, one the Great Pyramid in Egypt and the other Stonehenge in southern England, each recording a simple but effective model for the earth using the same metrological knowhow. see book page
Dear Friends: I have just finished this finest book I have ever encountered on the subject. Richard Heath has written with masterful confidence and great verbal elegance to bring this ancient “Pythagorean” science up to our moment in history—fully integrating contemporary developments in projective geometry and spiritual efforts to explicate meaning. Here is the “see and tell” method of the ancients employed to illuminate what we hide from ourselves.
Dear Richard, Many thanks for sending me 'Sacred Number'. I've been reading it and am very impressed by the way you approach this difficult subject to write about. Your grasp of it is quite admirable and so is your expression of it. I've talked about it with John Neal and we're both delighted with what you've done.
