Book CoverJohn Neal by John Neal, Secret Academy: London, 2000


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. 

by Professor Fred Hoyle, Freeman: San Francisco, 1977

Hoyle OSThis well written and produced book is the result of Fred Hoyle being asked to investigate the possible astronomical uses of the different parts of Stonehenge, after Gerald Hawkins (an English astronomer based in the US) had brought out his own book Stonehenge Decoded, to wide popular interest if not acclaim. In it

  • Chapter one describes the monument and how and with what it was constructed, with excellent map diagrams of how the stones must have been transported to the site.
  • Chapter two discusses the types of possible alignment to be found within the monument.
  • Chapter three discusses some practicalities behind eclipse prediction.
  • This enables the reader to judge Hawkin's ideas and provides the base from which Hoyle extends them.
  • Chapter five is about making eclipse predictions using a clock-like use of the Aubrey Holes.
  • Chapter six explores the cultural connections behind eclipses and their prediction, and Hoyle proposes that the lunar nodes could be seen as an invisible god, in the context of a trinity of Sun, Moon and Nodes.
  • Hoyle gives a very good explanation of the astronomical situation behind the behaviour of the sun, moon and eclipses in the Appendix. 

by John Michell, Thames & Hudson: London, revised edition of 1989

Michell 1989This is a readable and well-laid out book about how the idea of an ancient astro-archaeology developed from gentleman-antiquarian roots. In fact I need to read it again right away!

Letter to Robin Heath from Aubrey Burl
endorsing this book in 3 October, 2007

Dear Robin,

Very many thanks for your excellent Alexander Thom: Cracking Stone Age. It arrived quite late and I instantly began rereading it. You have written an extremely useful biography of an exceptional man. Thanks also for the ANL.


For my part I am glad that I was able to help him archeologically when none of my colleagues seemed to offer little more than polite interest or complete disdain. Although Colin Renfrew did congratulate me in finding an outlet for Thom's outstanding plans of stone circles.


And it was fortuitous that when the Thoms were making arrangements to go to Carnac without good plans I was able to send him two from German colleagues that were extremely detailed.



Given all that that he achieved for megalithic studies, 'awakening sleepers from their slumbers', remarked Richard Atkinson in another context, it is sad, as you say, that no university seems interested in a degree course devoted to his attainments. So I trust that Cracking the Code will provide a counter-balance to that willful prejudice. I wish the book every success and hope that it in its turn may disturb some of the somnolent Rip van Winkles of prehistoric studies.

Yours most sincerely,

Aubrey Burl

MorelyRenfrew AoMSaburo SugiyamaThis was a fabulous book for me in its article on the sacred precinct of Teotihuachan where Saburo Sugiyama (pictured) gives detailed conclusions about a Teoti Measurement Unit equal to 83 cm, this meticulously deduced from the main steps on pyramids. Along the Road of the Dead, the centres of Sun and Quetzalcoatl pyramids yielded 1440 TMU (actually 1439.75). many other measures of interest to the Maya calendar inherited (from the Olmec) involve the Tzolkin of 260 days and eclipse half year, in TMUs. Unfortunately Sugiyama cannot recognise an old world measure of the megalithic yard as the TMU (83cm = 2.723 ft very close to Alexander Thom's estimate at Avebury of 2.723 ft, within one 76th of an inch), perhaps because the New World is not allowed, in the current archaeological model of history, to have gained its measures (or pyramids, astronomy, sacred geometry, myths, etc..) from the Old World. see Measures section especially .

There are many excellent papers on other matters which make this volume very attractive for further research.
