Read a Classic The First Six Books of the Elements of Euclid in Which Coloured Diagrams and Symbols are Used Instead of Letters for the Greater Ease of Learners by Oliver Byrne. London: William Pickering. 1847. "An unusual and attractive edition of Euclid was published in 1847 in England, edited by an otherwise unknown mathematician named Oliver Byrne. It covers the first 6 books of Euclid, which range through most of elementary plane geometry and the theory of proportions. ... we have had the entire edition photographed ... [and] have mounted all of Byrne's book, but in the organization of the site is by no means final. We are still experimenting with the images to improve their quality, and sooner or later the structure found for Book VI, which is much better than the rest, will be transported to the other books. If you have any suggestions we'll be pleased to hear from you."
