"Tint and Form": The Geometric Philosophy Underlying Oliver Byrne's Elements

Abstract

Oliver Byrne published his ground-breaking and visually remarkable edition of Euclid’s Elements in 1847. The book is extraordinary: its pages are adorned with generous four-colour diagrams, illustrations and grids, and each proposition begins with an engraved decorative initial. Its aesthetic similarity to various stylistic themes of the Bauhaus and De Stijl movements has been noted, but little attention has been paid to the pedagogical and theoretical insights that shaped Byrne’s illustrative choices. In this article, the author explains some key philosophical ideas underlying the geometric illustrations and contextualises them amid Byrne’s wider mathematical preoccupations.
