The Diagram: Harmonic Geometry

by Adam Tetlow Author

In this installment in the Wooden Books Series, philosopher Adam Tetlow explores the ancient Helicon — not the brass instrument kind. This Helicon is an iconic diagram of antiquity; a reference used to output harmonic equations and fractions. Here, Tetlow will dive into this master diagram’s history and its different functions throughout. In line with other books of the series, this volume contains over 100 photographs to illustrate the functions and past of the Helicon.
