Section D'or

The Section d'Or ("Golden Section" in French), also known as Groupe de Puteaux or Puteaux Group, was a collective of painters and critics associated with an offshoot of Cubism known as Orphism.
 Many of these painters retained only the superficial appearance of Cubism, the geometrical fragmentation of the painted surface, and later turned in opposite directions, some going back to traditional formulae, while others were borne away by abstract currents or Dada experiments, but the unity of their search was based on a common admiration for Cézanne and his constructive lesson. The initiative and the title of this exhibition, which created a considerable stir, were due to the painter and engraver Jacques Villon. In his studio at Puteaux, near Paris, a number of artists passionately interested in problems of rhythm and proportion met on Sunday afternoons, among them the two theoreticians of Cubism, Gleizes and Metzinger, Picabia, Léger La Fresnaye, as well as the poets Paul Fort, Ribemont-Dessaignes, Jean Cocteau and Joachim Gasquet. Villon developed his theory of vision by pyramids, taken from Leonardo da Vinci, and suggested during these meetings the title of 'Section d'Or', borrowed from the treatise of the Bolognese monk Luca Pacioli, The Divine Proportion, published in Venice in 1509 and illustrated by Leonardo himself. 


Formulated by Vitruvius and taken up again during the Renaissance, the golden section or divine proportion (or gate of harmony) is the ideal relation between two magnitudes, expressed numerically as and demonstrated in many masterpieces of different arts, applied consciously or, more often, by instinct. 'There is,' Voltaire said, 'a hidden geometry in all the arts that the hand produces.' Although the golden section was not the only constant to which the Cubists referred for the mathematical organization of their canvas, it reflected the profound need for order and measure that they felt more through sensibility and reason than as a result of calculation. Distorted by the incomprehension or bad faith of critics, the 'Section d'Or' exhibition met with immense avant-garde success in France and abroad, and constituted a general rally under the sign of Cézannian architecture and geometrical discipline.

Artist ==> Albert Gleizes (Paris, 8 December 1881 – Avignon, 23 June 1953), was a French artist, theoretician, philosopher, a founder of Cubism and an influence on the School of Paris. Albert Gleizes and Jean Metzinger wrote the first major treatise on Cubism, Du "Cubisme", 1912. Gleizes was a founding member of the Section d'Or group of artists. He was also a member of Der Sturm, and his many theoretical writings were originally most appreciated in Germany, where especially at the Bauhaus his ideas were given thoughtful consideration. Gleizes spent four crucial years in New York, and played an important role in making America aware of modern art.
