Throughout history, the ratio for length to width of rectangles of 1.61803 398874989484820 has been considered the most pleasing to the eye. This ratio was named the golden ratio by the Greeks. In the world of mathematics, the numeric value is called “phi”, named for the Greek sculptor Phidias. The space between the columns form golden rectangles. There are golden rectangles throughout this structure which is found in Athens, Greece.

The human face is based on Phi and Golden Ratio proportions.
The human face abounds with examples of the Golden Ratio, also known as the Golden Section or Divine Proportion. Golden Ratio is a mathematical ratio that seems to appear recurrently in beautiful things in nature as well as in other things that are seen as “Beautiful”.
The “Golden Ratio” is a mathematical ratio of 1.618:1, and the number 1.618 is called “Phi“.
It has long been said that beauty is in the eye of the beholder and thought that beauty varies by race, culture or era. The evidence, however, shows that our perception of physical beauty is hard wired into our being and based on how closely the features of one’s face reflect phi in their proportions.
