The Golden Mean (also called The Golden Ratio, Phi, The Divine Proportion) is a simple ratio: 1 : 1.618 that is considered aesthetically beautiful, and which has been used in art and architecture for thousands of years. It is a bit like Pi – in that it is a difficult number to represent in numbers, but it arises naturally out of simple geometry… and like Pi, it is everywhere. Phi’s symbol is: phi
Phi frequently turns up in nature and in the horses body, particularly the feet and lower limb.
