~~last~~ second to last essay,
“Undergraduation”
contains as a footnote a link to Byrne’s
Euclid,

[a]n unusual and attractive edition of Euclid […] published in 1847 in England, edited by an otherwise unknown mathematician named Oliver Byrne. It covers the first 6 books of Euclid’s Elements of Geometry, which range through most of elementary plane geometry and the theory of proportions. What distinguishes Byrne’s edition is that he attempts to present Euclid’s proofs in terms of pictures, using as little text - and in particular as few labels - as possible. What makes the book especially striking is his use of colour. […]

It really looks like an excellent book, especially if you are easily
confused by short identifiers (that is, *one char*), possibly indexed
by another char. (I get reminded of Knuth’s “The Art Of Computer
Programming”…)

Still, the use of *no identifiers at all*, but graphics everywhere
can get pretty confusing,
too.
