Personal fav is "Dürer" that demonstrates Albrecht Dürers method of projecting a spiral.

Google: Rafael Araujo artist formula. Ahhhh! https://www.rafael-araujo.com/calculation
Now we are getting somewhere... and another that shows the process a bit better: https://hazelhomeartandantiques.blogspot.com/2015/04/the-cal...
Now I am trawling github to see if I can find some processing or similar libraries that I can play around with. Golden Ratio sketches, defining physical objects and shapes from purely mathematical constructions... I love rabbit holes!

I recently heard the saying "a great artist knows when to stop" (it was Ben Afflek talking about AI art - I guess he was quoting someone?). I feel like in the case of these drawings, less detail would actually be better. More readable, perhaps.
Still, an impressive amount of effort for each one, given only straightedge and compass.

Yikes. The golden ratio has limited significance, nothing to do with spirituality, and little presence in nature [1]. Araujo's pictures look great, but in almost any of them you could replace the golden ratio with 1.6, 1.7, or 1.5, and get something no less beautiful.
The Wikipedia page is fairly good on this, especially the "Disputed observations" section: https://en.wikipedia.org/wiki/Golden_ratio#Disputed_observat...
As a mathematician, fetishisation of the golden ratio bugs me.
[1] The main place is spiral arrangements of leaves, petals, etc. Vi Hart explains why (watch all three parts): https://www.youtube.com/watch?v=ahXIMUkSXX0
