In 1972 and 1973 we made two further expeditions to Carnac.! Much new and useful information was obtained, but the most important task which we completed was a survey of the Kermario alignments from end to end, to a scale of 1: 500. In 1973 the survey was checked on the ground and carried further east into the woods where we found a number of fallen stones, and still further on we found an upright six-foot menhir E (see Figure 1) which probably belongs to the alignments. 'This is on the field… 
The Two Megalithic Lunar Observatories at Carnac
In a previous paper! we showed that it is probable that there were two large Megalithic lunar observatories in the Carnac area. One was centred in the large menhir on the hilltop at Le Manio and the

Paleolithic and Neolithic Cultures
For most of the Paleolithic period [or Old Stone Age, beginning more than ~21/2 million years before present (b.p.)], there are few materials that could be interpreted as relevant to human
A Bayesian Analysis of the Megalithic Yard
A new analysisis presented of Thorn's data on the megalithic stone circles in Britain and the stone rows in the Carnac region of France. The approach is Bayesian and is aimed at examining plausible

A statistical approach to latitude measurements: Ptolemy's and Riccioli's geographical works as case studies
Abstract. The aim of this work is to analyze latitude measurements typically used in historical geographical works through a statistical approach. We use two sets of different age as case studies:
The Megalithic Yard
A brief account is given of the reason for our belief in the existence of the megalithic yard. The statistical background is explained. It is shown that megalithic surveyors could attain an accuracy
Median spheres: theory, algorithms, applications
The present results show that for each finite data set there exists at least one weighted median generalized hypersphere, and lend credence to a variant of a method used by archaeologists, and explain some findings from operations research.


The Astronomical Significance of the Large Carnac Menhirs
We find in Britain many indications that in Megalithic times the Sun, Moon and stars were carefully observed at rising or setting. Probably no great accuracy was needed for stellar observations where
