"The things that are endowed correct proportions delight the senses. "
Saint Thomas Aquinas (1225-1274)

Natural phenomena as different as the arrangement of a sunflower, the spiral of the shell of the nautilus or the arms of the Milky Way have in common a geometric rule of harmony. Known since antiquity, it is found in architecture as the Parthenon or the Great Pyramid. She is also present in the work of great artists such as Leonardo da Vinci.


This geometric rule of harmony is defined by a number, the "golden number", of a value of 1. 6180339887. It defines the "divine proportion" or " gold proportion ".


The use of the golden ratio has made it possible to map the human face. Plus the proportions of the face approach the ratio of the golden ratio, 1.618 and more they are perfect, which makes a person pleasant and pleasant to the eye that looks at it.

We analyze the face from 12 points including the eyes, the nose, the chin, the mouth, the eyebrows, the jaw and the shape of the face.


A face will be considered beautiful "mathematically" if the different ratios of its face respect the golden ratio .
A harmony compass is used as a tool to check the presence of the golden ratio.

The usefulness of these measures is to harmoniously correct a face to improve its beauty and attractiveness thanks to the golden ratio. This helps to respect the overall balance of the face. Thus, areas that need to be corrected by avoiding any form of standardization are precisely defined.
