“Cubism is no different from any other school of painting. The same principles and the same elements are common to all. The fact that for a long time cubism has not been understood and that even today there are people who cannot see anything in it, means nothing. I do not read English, and an English book is a blank to me. This does not mean that the English language does not exist, and why should I blame anyone but myself if I cannot understand what I know nothing about?” -- Picasso
"Negro" Period

In 1907, after numerous studies and variations Picasso painted his first Cubist picture - “Les demoiselles d’Avignon”. Impressed with African sculptures at an ethnographic museum he tried to combine the angular structures of the “primitive art” and his new ideas about cubism. The critics immediately dubbed this stage in his work the "Negro" Period, seeing in it only an imitation of African ethnic art. “In the Demoiselles d’Avignon I painted a profile nose into a frontal view of a face. I had to depict it sideways so that I could give it a name, so that I could call it ‘nose’. And so they started talking about Negro art. Have you ever seen a single African sculpture -- just one -- where a face mask has a profile nose in it?” Picasso wrote. Picasso’s new experiments were received very differently by his friends, some of whom were sincerely disappointed, and even horrified, while others were interested. The art dealer Kahnweiler loved the Demoiselles and took it for sale. Picasso’s new friend, the artist Georges Braque (1882-1963), was so enthusiastic about Picasso’s new works that the two painters came together to explore the possibilities of cubism over several of the following years. In the summer of 1908, the two began their experiments by going on holidays in the countryside. Afterwards, they found that they had painted very similar pictures completely independently of each other.
Analytical Cubism
Bread and Fruit Dish on a Table (1909) marks the beginning of Picasso’s “Analytical” Cubism: he gives up a central perspective and splits forms up into facet-like stereo-metric shapes. The famous portraits of Fernande, Woman with Pears, and of the art dealers Vollard and Kahnweiller are fulfilled in the analytical cubist style . By 1911, Picasso’s relationship with Fernande went through a crisis. He broke up with her and started a liaison with Eva Gouel (Marcelle Humbert), whom he called “Ma Jolie”.
Synthetic or Collage Cubism
By 1912 the possibilities of analytical cubism seemed to be exhausted. Picasso and Braque began new experiments. Within a year they were composing still lifes of cut-and-pasted scraps of material, with only a few lines added to complete the design, such as Still-Life with Chair Caning. These collages led to synthetic cubism -- paintings with large, schematic patterning, such as The Guitar. “Cubism has remained within the limits and limitations of painting, never pretending to go beyond. Drawing, design and color are understood and practiced in cubism in the spirit and manner that are understood and practiced in other schools. Our subjects might be different, because we have introduced into painting objects and forms that used to be ignored. We look at our surroundings with open eyes, and also open minds. We give each form and color its own significance, as we see it; in our subjects, we keep the joy of discovery, the pleasure of the unexpected; our subject itself must be a source of interest. But why tell you what we are doing when everybody can see it if they want to?” wrote Picasso. World War I (1914-18) changed the life, mood, state of mind, and, of course, art of Picasso. His fellow French artists, Braque and Derain, were called up into the army at the beginning of the war. The art dealer Kahnweiler, a German, had to go to Italy, and his gallery was confiscated. Picasso’s pictures became somber, showing realistic more often, for example Pierrot.

“When I paint a bowl, I want to show you that it is round, of course. But the general rhythm of the picture, its composition framework, may compel me to show the round shape as a square. When you come to think of it, I am probably a painter without style. ‘Style’ is often something that ties the artist down and makes him look at things in one particular way, the same technique, the same formulas, year after year, sometimes for a whole lifetime. You recognize him immediately, for he is always in the same suit, or a suit of the same cut. There are, of course, great painters who have a certain style. However, I always thrash about rather wildly. I am a bit of a tramp. You can see me at this moment, but I have already changed, I am already somewhere else. I can never be tied down, and that is why I have no style,” Picasso wrote.
In 1916, the young poet Jean Cocteau brought the Russian ballet impresario Diaghilev and the composer Erik Satie to meet Picasso in his studio. They asked him to design the décor for their ballet “Parade”, which was to be performed by Diaghilev's Ballet Russe. The meeting and Picasso’s affirmative answer would bring major changes to his life in the followng years. In 1917, he traveled to Rome with Cocteau and spent time with Diaghilev’s ballet company, working on décor for “Parade”. There, Picasso met Igor Stravinsky and fell in love with the dancer Olga Khokhlova. He accompanied the ballet group to Madrid and Barcelona because of Olga, and eventually persuaded her to stay with him.
