Revisiting the Megalithic Yard

Abstract

A long-standing question in British archaeology is whether a standard unit of linear measure was used by Neolithic architects and engineers in the construction of megalithic circles. Well-developed trade networks were established throughout the Near East into northern Europe by 4000 BC and commerce required standardized measure of trade goods. Well before this time, standardized linear measure was in use for surveying in the Tigris, Euphrates, and Nile agricultural regions. Growing evidence, such as the Folkton and Lavant chalk drums, suggest that Neolithic construction included standard measurements. We suggest that measurement standards were introduced in Britain with the immigration of Neolithic people about 4000 BC.
