ABSTRACT
We know that stone circles, in Britain and elsewhere, were laid out some 4,000 years ago as instruments by which men could observe the heavens to predict eclipses and movements of sun, moon and stars. These circles were so sited that alignments between heavenly bodies and certain landmarks met within the perimeters of stone. There they formed geometrical patterns illustrating mathematical concepts so advanced as to be incompatible with stories of a primitive prehistoric society.
