AstronomyandMeasurement Harris cover 160pxA work within the genre of megalithic science with its own thesis. Much data to consider.

This booklet was strongly influenced by Barnett (1978) and Thom, and proposes a new unit called a megalithic foot (MF) which seems to divide into integral dimensions measured using the megalithic yard so as to obtain astronomical time periods, notably the eclipse year of 346.62 days, yet often times other multiples. Just as Thom was criticised by Neal for documenting sites using a rather variable averaged megalithic yard of 2.72 feet (+/- 0.02), this book gives results in the newly declared MF so that without resort to sources, one cannot verify rather than simply accept what is proposed. 

Back Matter

The great monuments of prehistoric Britain have been a constant source of curiosity and theory since their construction principles were first forgotten, millennia ago.

It has long been argued that the megalith builders used a standard measurement which naturally enough is not the same as any we use today. A number of proposed measurements have been put forward, the best known of which is the Megalithic Yard of Alexander Thom.

Thom 's measure has come under critical study in recent decades. Here the authors suggest a new measurement, a refinement not so far different from Thom's Megalithic Yard, that more satisfactorily accounts for the lay-out of a greater number of our ancient sites

A selection of sites, from stone circles to Ilkley's Swastika Stone, drawn from across the British Isles and Brittany, are presented to illustrate this new hypothesis.
