This article shows that Les Table des Marchands chambered monument (at Locmariaquer, by Carnac, southern Brittany) is built to have the midsummer sun just enter along its corridor whilst the moon at its maxumum standstill shines directly down it. Crowhurst points out that the solstitial sun angle runs along the five side of a 3-4-5 Pythagorean triangle relative to east-west, at Carnac, and how a scheme of lunar squares was employed in the greater Carnac site, a scheme that (a) notes the maximum and minimum lunar sunrise and sunset angles over many kilometers using a simplified geometrical construction and (b) allows the metrological scheme of the builders to be revealed, a scheme that employed megalithic yards and a unit very close to the modern metre.
Drawing on extactly similar Chinese silk hangings, the author develops a simple yet compelling scheme that highlights the original presentation of spiritual archetypes by the builders of the early Carnac monuments. These have resonances throughout later human development of spiritual places including Cathedrals, indicating their fundamental importance to later human development. The work at Carnac appears to have preceeded the building of any part of Stonehenge.

By Richard Heath
This article reports on the insights derived from a visit during 2007 summer solstice at the Carnac megalithic complex in Brittany. Following on from the author's recognition of the metrology of the well-known 3,4,5 triangle, documented in his Sacred Number book, local researcher Howard Crowhurst had identified a continuous grid of near squares and double squares that define a grid for observation of many different sightlines to the Moon's Maximum and Minimum phenomena. When Crowhurst's work is digested, the nature of the grid has rational metrological tangent lengths that would have facilitated the many sightlines achieved and could have formed the original discovery methodology that made the work itself possible.

(A Brief Introduction)
"The history of archaeoastronomy began with the gradual recognition of the existence and importance of prehistoric sites in the country. Once recognised as man-made engineering projects, gradually the records and plans were made of the sites which now enable people to calculate their relationship with the sky...."

The stadia mentioned in the title of this work are not the principle subject; they have been selected as an excellent example of the values of length exemplified in ancient metrology. Firstly, the lengths of the running tracks of ancient Greece from whence comes the term “stadium” will be investigated. Then other recorded values of the “stade” that are not associated with the race tracks will be specified and their metrology explained. Corroboration of the foot measures will be given in the appendices ....
... The proof of the system as outlined is the fact that measures from the field so often conform to extreme degrees of accuracy with those that are proposed by the simple arithmetic of ancient metrology.

The Astronomical Significance of Llech y Drybedd |

By Robin Heath
Llech y Drybedd holds a duplex astronomical significance. As a solar backsight, it appears to have been located where it is in order for the midsummer sunset around 2700 BC to occur directly behind Lugnaquilla mountain, in Wicklow, Ireland, some 93 miles away. As a lunar foresight for the major standstill moonset an inevitable consequence is that observations must have been made back from Llech y Drybedd along the alignment marked by the three (constructed) sites.
