In Figure I of our previous paper,' a key plan is given showing the arrangement of the Carnac alignments and some of the nearby large menhirs. It is shown there that solar and lunar backsights and foresights are to be found among these menhirs, and that the converging rows of stones at Petit Menec and at St Pierre probably form extrapolating sectors for use in making lunar observations with Er Grah (Le Grand Menhir Brise), It seems possible that the main alignments were intended for the…

The Kerlescan Cromlechs
It is known! that for setting out long lengths the builders of Megalithic sites in Britain normally used a unit of 2t Megalithic yards (my) and that their closed rings had perimeters integral in this

The Ring The Orkney Islands are rich in archaeological sites of many kinds and periods, but perhaps the most impressive is the Ring of Brogar (see Figure 2). It stands in a commanding position on the

An astronomical interpretation of the British standing stone sites has been developed in great detail by A. Thom using methods and data which have hitherto rarely, if ever, been used by
Ludovic McLellan Mann's place in the history of prehistoric metrology
Megalithic metrology, the notion that Neolithic monument builders employed a standard unit of measurement when setting out stone circles, has a long history. William Stukeley was the first to sugge...
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.
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 accuracy of megalithic man’s linear measurements is shown by recent work in Orkney and Brittany. Everywhere his geometry is based on integral right-angled triangles. The Sun was observed at the


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
