Charming old site!

It would be neat to see it updated to something along the lines of:

https://507movements.com/

That said, most folks would be better served by:

https://www.goodreads.com/book/show/16086997-why-knot-how-to...

or some other text with clear illustrations and instructions, or if one wants something comprehensive:

(note that in the literature, knots are referred to by their ABOK#)

Agree with the other commenter - this is very charming! I find it a wonderfully romantic idea to contemplate that, at some point in human past, studying and developing new knots (or even stumbling upon new knots and sharing that idea) would have been a realistic endeavour that expanded the boundary of human knowledge and gave us newer or safer ways of building and achieving things.

Animated Knots by Grog[1] and 3D Knots[2] are oft-cited places to learn knots on the internet, but OP's is such a nice throwback. Don't miss the "requested entries" page with 28 more knots![3]
