Publisher Kronecker Wallis sells an expanded edition of Byrne's opus which includes all thirteen books of Euclid's Elements. It also appears to be reset in a modern typeface.
I have this book in print and that is my main complaint. It explains the typographical history and I get it…but it still makes it harder to read than necessary.
There used to be two forms of letter s, long s when medial and short s when final, similar to the two forms of sigma in later Greek. The integral sign derived from this. https://en.wikipedia.org/wiki/Long_s
Seems like a weird choice to make it colored, interactive etc. - presumably to maximize accessibility/digestibility by laymen - and then adopt an outdated typography choice for coherence with a 180 year old edition
The colors and the weird s were both from the 180 year old version. The interactivity is new. Here's the author's thoughts:
> Creating a faithful online reproduction of a book considered one of the most beautiful and unusual publications ever published is a daunting task. Byrne’s Euclid is my tribute to Oliver Byrne’s most celebrated publication from 1847 that illustrated the geometric principles established in Euclid’s original Elements from 300 BC.
> The long s (ſ) was common in older publications and is used throughout the book. Even though it’s commonly mistaken for the lowercase f, I felt reproducing it was also important to stay true to the original.
> I wanted to add interactivity to the diagrams to aid in understanding them because I had some trouble understanding some in the original book.
Oliver Byrne’s 1847 edition of the elements did have colored designs [0]. This website features a digitization of Byrne’s book and defaults to the text as it appears in the original.
