The First Six Books of the Elements of Euclid


Oliver Byrne - 1847
     Euclid in living color   Nearly a century before Mondrian made geometrical red, yellow, and blue lines famous, 19th century mathematician Oliver Byrne employed the color scheme for the figures and diagrams in his most unusual 1847 edition of Euclid's Elements. The author makes it clear in his subtitle that this is a didactic measure intended to distinguish his edition from all others: “The Elements of Euclid in which coloured diagrams and symbols are used instead of letters for the greater ease of learners.” As Surveyor of Her Majesty’s Settlements in the Falkland Islands, Byrne had already published mathematical and engineering works previous to 1847, but never anything like his edition on Euclid. This remarkable example of Victorian printing has been described as one of the oddest and most beautiful books of the 19th century. Each proposition is set in Caslon italic, with a four-line initial, while the rest of the page is a unique riot of red, yellow, and blue. On some pages, letters and numbers only are printed in color, sprinkled over the pages like tiny wild flowers and demanding the most meticulous alignment of the different color plates for printing. Elsewhere, solid squares, triangles, and circles are printed in bright colors, expressing a verve not seen again on the pages of a book until the era of Dufy, Matisse, and Derain.

The Mathematical Analysis of Logic


George Boole - 1847
    His Mathematical Analysis of Logic, first published in 1847, was the ground-breaking work that laid the foundations for what is known today as Boolean algebra and the propositional calculus. Written in response to the altercation between Sr. William Hamilton and Augustus de Morgan over the quantification of the predicate within syllogistic theory, its remarkable innovations led other logicians, among them William Stanley Jevons, John Venn, Charles Sanders Peirce, and Ernst Schroder, to refine and develop Boole's system. In turn, their efforts were incorporated by Alfred North Whitehead and Bertrand Russell into the monumental system of Principia Mathematica. In short, modern symbolic logic was founded in the pages of this book.
