Just looking out some stories for the Math/Maths Podcast and, from Tony Mann’s Twitter stream, I came across a review in the New York Times of a facsimile of 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, from which is quoted:

The arts and sciences have become so extensive, that to facilitate their acquirement is of as much importance as to extend their boundaries.

Oliver Byrne, 1847
