Byrne's Euclid

This is a digital reproduction of Oliver Byrne's 1847 illustrated edition of Euclid's Elements, featuring the first six books covering plane geometry, geometric algebra, circles, polygons, ratios, and proportions. The project includes interactive diagrams, cross-references, and supplementary materials like posters and puzzles designed by Nicholas Rougeux. The site provides both educational access to Byrne's original colorful geometric diagrams and information about how the modern digital version was created.
