Title: Cubism
Content: art. Artists such as Paul Gauguin, Henri Matisse, and Pablo Picasso were intrigued and inspired by the stark power and simplicity of styles of those foreign cultures. Around 1906, Picasso met Matisse through Gertrude Stein, at a time when both artists had recently acquired an interest in primitivism, Iberian sculpture, African art and African tribal masks. They became friendly rivals and competed with each other throughout their careers, perhaps leading to Picasso entering a new period in his work by 1907, marked by the influence of Greek, Iberian and African art. Picasso's paintings of 1907 have been characterized as Protocubism,

Title: Jean Metzinger
Content: see the cubist works in Room 7 and 8. While Pablo Picasso and Georges Braque are generally acknowledged as the founders of the twentieth-century movement that became known as Cubism, it was Jean Metzinger, together with Albert Gleizes, that created the first major treatise on the new art-form, "Du "Cubisme"", in preparation for the Salon de la Section d'Or held in October 1912.

As art historian Peter Brooke points out, Gris started painting persistently in 1911 and first exhibited at the 1912 Salon des Indépendants (a painting entitled "Hommage à Pablo Picasso").

Art historian Christopher Green writes that the "deformations of lines" allowed by mobile perspective in the

Title: Pablo Picasso
Content: the premier French art dealers of the 20th century. He was among the first champions of Pablo Picasso, Georges Braque and the Cubism that they jointly developed. Kahnweiler promoted burgeoning artists such as André Derain, Kees van Dongen, Fernand Léger, Juan Gris, Maurice de Vlaminck and several others who had come from all over the globe to live and work in Montparnasse at the time. Picasso's African-influenced Period (1907–1909) begins with his painting "Les Demoiselles d'Avignon".

Several major artistic movements flourished in Paris at this time, including Cubism, Surrealism, and Art Deco. The American art patron Gertrude Stein, resident in Paris, played an important role in encouraging and buying works of Picasso and other artists of the period.
