# THE GOLDEN SECTION

Astonishing golden section, φ, which can be observed in the conceptual field of the Euclidian geometry, in the proportions of the human body, as well as in Fibonacci’s study on rabbits population (1).

It is also to be found in the geometry of plants, namely in the pentagon and in the number of petals of numerous flowers. The golden section is inherent to 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 even found it in the number of individuals present 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.

Therefore, the golden section is intrinsic to a vast number of natural forms and events. So is φ part of what human beeings feel as beeing proportionate, as it is naturally present in the environment, in the geometric harmony and, in the balance of the internal living forces.

For these reasons, the size of most my canvases is determined according to the golden section.

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.
