TL;DR

I had my mind blown discovering the beautiful digitization of Euclidâ€™s Elements.

The First Six Books of The Elements of Euclid With Coloured Diagrams and Symbols

The site has it:

A reproduction of Oliver Byrneâ€™s celebrated work from 1847 plus interactive diagrams, cross references, and posters designed by Nicholas Rougeux

# Is it easy?

Wellâ€¦ yes and no. If youâ€™re used to math symbolism (as I assume to be), youâ€™ll have to re-learn it in favor of shapes and colors.

One thing that puzzled me a bit was the Pythagoraâ€™s Theorem demonstration (i.e. Proposition XLVII), when it says that the area of the red square is twice the area of a specific triangle - the following picture shows it:

After sweating a bit, and looking in Google, it was clear that the square and the triangle share both the same base and the same height, hence their areasâ€™s ratio must be two.

# So long!

What to say more? Go take a look, itâ€™s amazing! Be sure to click on the pictures in the demonstrations, they will highlight stuff in the pictures on the side (where it makes sense), making it awesomely comfortable to follow.
