This article shows that the Gavinis chambered monument is built to have the midsummer sun just enter along its corridor whilst the moon at its maxumum standstill shines directly down it. Since the sun angle describes a 3-4-5 Pythagorean triangle, then a scheme of lunar squares emerges that 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.

Drawing on extactly similar Chinese silk hangings, the author presents a simple yet compelling scheme that highlights the simplicity achieved by the builders of the early Carnac monuments and the subtlety that has, so far, been overlooked. Their work appears to have preceeded the building of any part of Stonehenge.

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.

Evidence for a Neolithic National Grid and

IMPORTANT NEW EVIDENCE OF GEODETIC INTENT
IN THE LOCATION OF STONEHENGE by Robin Heath

This present work represents something of a breakthrough in understanding the megalithic culture, because it overcomes a previously encountered difficulty where forms that suggest a geodetic(man-made) form and intent contain defining sites that are a mixture of constructed and natural features. This report describes an example of prehistoric geodesy where all the sites that make up the employed geometry are both well known and built megalithic monuments.

The geometry employed will be seen to be familiar, and integrates geometrically and metrologically within the geometry and metrology of the previously revealed Stonehenge-Preseli-Lundy rectangle. In addition, the geometry replicates the commonest design structure that defines many megalithic rings, as originally discovered by professor Thom.

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.

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.

(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...."
