Dynamic Symmetry

It is believed, and many have thought to have proven that in nature there exists a set of correlating principals which are the bases for all design in nature and in art. 

The basic principals manifest themselves in nature in many ways, including the well known nautilus shell and also leaf patterns distributed on plants.

There is evidence these  principal was discovered by the Egyptians and refined by the Greeks. They evolved the principles to near perfection, and  converted them to law, requiring approvals for all building and sculpture.
