exhibiting them in her informal Salon at her home in Paris. At one of her gatherings in 1905 he met Henri Matisse (1869–1954), who was to become in those days his chief rival, although in later years a close friend. The Steins introduced Picasso to Claribel Cone (1864–1929), and her sister Etta Cone (1870–1949), also American art collectors, who began to acquire Picasso and Matisse's paintings. Eventually Leo Stein moved to Italy, and Michael and Sarah Stein became important patrons of Matisse, while Gertrude Stein continued to collect Picasso. Rivalry with Matisse The Salon d'Automne of 1905 brought notoriety and attention to the works of Henri Matisse and the Les Fauves group. The latter gained their name after critic Louis Vauxcelles described their work with the phrase "Donatello chez les fauves" ("Donatello among the wild beasts"), contrasting the paintings with a Renaissance-type sculpture that shared the room with them. Henri Rousseau (1844–1910), an artist whom Picasso knew and admired and who was not a Fauve, had his large jungle scene The Hungry Lion Throws Itself on the Antelope also hanging near the works by Matisse and which may have had an influence on the particular sarcastic term used in the press. Vauxcelles' comment was printed on 17 October 1905 in the daily newspaper Gil Blas, and passed into popular usage. Although the pictures were widely derided—"A pot of paint has been flung in the face of the public", declared the critic Camille Mauclair (1872–1945)—they also attracted some favorable attention. The painting that was singled out for the most attacks was Matisse's Woman with a Hat; the purchase of this work by Gertrude and Leo Stein had a very positive effect on Matisse, who was suffering demoralization from the bad reception of his work. Matisse's notoriety and preeminence as the leader of the new movement in modern painting continued to build throughout 1906 and 1907, and Matisse attracted a following of artists including Georges Braque (1880–1963), André Derain (1880–1954), Maurice de Vlaminck (1876–1958). Picasso's work had passed through his Blue period and his Rose period and while he had a considerable following his reputation was tame in comparison to his rival Matisse. The larger theme of Matisse's influential Le bonheur de vivre, an exploration of "The Golden Age", evokes the historic "Ages of Man" theme and the potentials of a provocative new age that the twentieth century era offered.
