Publisher's Synopsis
What prehistoric artefact is found in every classroom? What is the oldest scientific instrument? Why does geometry mean 'earth measure'? What does perspective drawing have in common with the Great Pyramid? In this ground-breaking book, artist Adam Tetlow introduces the ancient harmonic number science of metrology, used since palaeolithic times to determine musical scales, and measure, design and build stone circles, earthworks, temples, churches and cities all over the world.
