# THE GOLDEN SECTION

Astonishing golden section, φ, which is found in the conceptual field of the Euclidian geometry, the proportions of the human body, and in Fibonacci’s study on rabbit’s population (1).

It also appears in the geometry of plants through the pentagon and the number of petals of numerous flowers. He is integrally part of the logarithmic spiral which forms the shell observed in nautiloïds (2).In the human body, the golden section is observed in the ratio between the height of the individual and the distance from navel to ground.

Fibonacci has found the golden section in the number of individuals in rabbit populations growing as

terms of the series of the same name, the ratio of a term to its preceding one tending towards φ.

The golden section is therefore intrinsic to a vast number of natural forms and events. Thus is φ part

of the human feeling of proportion, as being naturally inscribed in the environment, in the geometric harmony and, in the balance of the internal living forces.

All those observations determine the size of most my canvases.

The series of “Spirals” paintings is based on the geometry of the golden rectangle in which the ratio width-length is equal to the golden section φ.The link with Fibonacci series is in all serial paintings.
