Mathematical Treasures - Oliver Byrne's Euclid

Frank J. Swetz and Victor J. Katz



This is the title page of Oliver Byrne’s 1847 edition of Euclid's Elements, the first six books. Using color and pictures, Byrne attempted to teach Euclid's geometry by minimizing textual discussion, including labels. This innovative approach stressed visualization. The picture on this page illustrates Euclid’s Proposition 47 of Book I, the Pythagorean Theorem. Oliver Byrne (1810-1880) was trained as a civil engineer but was also employed as a surveyor and a sometime professor of mathematics. Augustus DeMorgan described him as “eccentric and a minor mathematician.” However, his Elements of Euclid was proudly displayed at The Great Exhibition of 1851 and credited with being “one of the oddest and most beautiful books of the century.”
