St Andrews has posted an edition of Euclid that is a richly saturated, tri-tone experiment in explaining the complexities of the foundations of geometry through shape and colour. This work, from the mid-19th century, conjures up Mondrian paintings, or Bauhaus and De Stijl schools of design. The following link offers a look at the work and some commentary: https://standrewsrarebooks.wordpress.com/2016/01/28/reading-the-collections-week-46-math-becomes-art-in-byrnes-1847-colourful-euclid/
