I think everyone knows about the golden ratio or the divine proportion (I got to know more about it after reading the wikipedia article on it). It's present everywhere in nature and also in the human body.
When I googled for golden ratio, I found links to a lot of myths behind it. I would like to know how important it was historically. Also are there any religious references?
How did people know about the golden ratio in ancient times? Some of the articles I read were about how important it was to ancient Greeks and other civilizations but none of them talked about how they found it and why they thought its important to use it in everyday life.
