Impact

Although Les Demoiselles had an enormous and profound influence on modern art, its impact was not immediate, and the painting stayed in Picasso's studio for many years. At first, only Picasso's intimate circle of artists, dealers, collectors and friends were aware of the work. Soon after the late summer of 1907, Picasso and his long-time lover Fernande Olivier (1881–1966) separated. The re-painting of the two heads on the far right of Les Demoiselles fueled speculation that it was an indication of the split between Picasso and Olivier. Although they later reunited for a period, the relationship ended in 1912.

A photograph of the Les Demoiselles was first published in an article by Gelett Burgess entitled "The Wild Men of Paris, Matisse, Picasso and Les Fauves", The Architectural Record, May 1910.

Les Demoiselles would not be exhibited until 1916, and not widely recognized as a revolutionary achievement until the early 1920s, when André Breton (1896–1966) published the work. The painting was reproduced again in Cahiers d'art (1927), within an article dedicated to African art.

Richardson goes on to say that Matisse was irate upon seeing the Demoiselles at Picasso's studio. He let it be known that he regarded the painting as an attempt to ridicule the modern movement; he was outraged to find his sensational Blue Nude, not to speak of Bonheur de vivre, overtaken by Picasso's "hideous" whores. He vowed to get even and make Picasso beg for mercy. Just as the Bonheur de vivre had fueled Picasso's competitiveness, Les Demoiselles now fueled Matisse's.

Among Picasso's closed circle of friends and colleagues there was a mixture of opinions about Les Demoiselles. Georges Braque and André Derain were both initially troubled by it although they were supportive of Picasso. According to William Rubin, two of Picasso's friends, the art critic André Salmon and the painter Ardengo Soffici (1879–1964), were enthusiastic about it while Guillaume Apollinaire (1880–1918) was not. Both the art dealer-collector Wilhelm Uhde (1874–1947), and Kahnweiler were more enthusiastic about the painting however.

According to Kahnweiler Les Demoiselles was the beginning of Cubism. He writes:

Early in 1907 Picasso began a strange large painting depicting women, fruit and drapery, which he left unfinished. It cannot be called other than unfinished, even though it represents a long period of work. Begun in the spirit of the works of 1906, it contains in one section the endeavors of 1907 and thus never constitutes a unified whole.

The nudes, with large, quiet eyes, stand rigid, like mannequins. Their stiff, round bodies are flesh-colored, black and white. That is the style of 1906.

In the foreground, however, alien to the style of the rest of the painting, appear a crouching figure and a bowl of fruit. These forms are drawn angularly, not roundly modeled in chiaroscuro. The colors are luscious blue, strident yellow, next to pure black and white. This is the beginning of Cubism, the first upsurge, a desperate titanic clash with all of the problems at once.
