the two 3-4-5 Pythagorean triangles formed by the diagonal have sides which are multiples of 10 megalithic yards. Thom (1967, 1968) has shown that megalithic man, when constructing stone circles and rings in Britain, often dealt in multiples of 2 2, 5, and 10 megalithic yards, and employed perfect Pythagorean triangles in the geometry of the construction of numerous stone rings. Thom and Thom (1972) have shown that the main Carnac alignments were set out with a unit of 2 2 megalithic yards, and…

It is becoming apparent that megalithic man possessed and used a considerable knowledge of geometry. As more of his constructions are unravelled, we obtain an increasing appreciation of his

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
