This is Neal's extrapolation into the structure underlying Historical Metrology. John Michell wrote the first book on what came to be called Ancient Metrology (1981), a slim volume in which two of the key ratios found within the ancient model of the earth (440:441 & 175:176, deducable from monuments such as Stonehenge) were not yet integrated. It fell to Neal to realise that a two dimensional grid of these ratios explained the majority of historical measures as belonging to a set of rational modules each rationally related to the English foot, chosen to represent one or unity for the ancient system of measure. All manner of Berriman's and other insights connecting historical measures fell into place. Much of my own work on monuments reported here and in my later books derives from this system which then gives insight into the numerical sciences so as to reveal an intellectual life of either unrecorded cultures, such as the megalithic, or where the ancient world failed to write down secrets or writings have failed to survive.
There is a project underway to collect and publish John Neal's other essays upon metrology into what looks like being a set of three volumes, the first of which called Ancient Metrology Vol I: A Numerical Code - Metrological Continuity in Neolithic, Bronze and Iron Age Europe (2016) is now available.
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.
