Henri Rousseau in the context of "Aviation in the pioneer era"

The Musée de l'Orangerie (English: Orangery Museum) is an art gallery of Impressionist and Post-Impressionist paintings located in the west corner of the Tuileries Garden next to the Place de la Concorde in Paris. The museum is most famous as the permanent home of eight large Water Lilies murals by Claude Monet, and also contains works by Paul Cézanne, Henri Matisse, Amedeo Modigliani, Pablo Picasso, Pierre-Auguste Renoir, Henri Rousseau, Alfred Sisley, Chaïm Soutine, Maurice Utrillo, and others.

Naïve art is usually defined as visual art that is created by a person who lacks the formal education and training that a professional artist undergoes (in anatomy, art history, technique, perspective, ways of seeing). When this aesthetic is emulated by a trained artist, the result is sometimes called primitivism, pseudo-naïve art, or faux naïve art.

Unlike folk art, naïve art does not necessarily derive from a distinct popular cultural context or tradition; indeed, at least in the advanced economies and since the Printing Revolution, awareness of the local fine art tradition has been inescapable, as it diffused through popular prints and other media. Naïve artists are aware of "fine art" conventions such as graphical perspective and compositional conventions, but are unable to fully use them, or choose not to. By contrast, outsider art (art brut) denotes works from a similar context but which have only minimal contact with the mainstream art world.

291 is the commonly known name for an internationally famous art gallery that was located in Midtown Manhattan at 291 Fifth Avenue in New York City from 1905 to 1917. Originally called the "Little Galleries of the Photo-Secession", the gallery was established and managed by photographer Alfred Stieglitz.

The gallery is recognized for two achievements: First, its exhibitions helped bring art photography to the same stature in America as painting and sculpture. Pioneering artistic photographers such as Stieglitz, Edward Steichen, Alvin Langdon Coburn, Gertrude Käsebier and Clarence H. White all gained critical recognition through exhibitions at 291. Equally important, Stieglitz used this space to introduce to the United States some of the most avant-garde European artists of the time, including Henri Matisse, Auguste Rodin, Henri Rousseau, Paul Cézanne, Pablo Picasso, Constantin Brâncuși, Marcel Duchamp, and the Dadaist Francis Picabia.

In the arts of the Western world, Primitivism is a mode of aesthetic idealization that means to recreate the experience of the primitive time, place, and person, either by emulation or by re-creation. In Western philosophy, Primitivism proposes that the people of a primitive society possess a morality and an ethics that are superior to the urban value system of civilized people.

In European art, the aesthetics of primitivism included techniques, motifs, and styles copied from the arts of Asian, African, and Australasian peoples perceived as primitive in relation to the urban civilization of Western Europe. In that light, the painter Paul Gauguin's inclusion of Tahitian imagery to his oil paintings was a characteristic borrowing of technique, motif, and style that was important for the development of Modern art (1860s–1970s) in the late 19th century. As a genre of Western art, Primitivism reproduced and perpetuated racist stereotypes, such as the "noble savage", with which colonialists justified white colonial rule over the non-white other in Asia, Africa, and Australasia.

The Repast of the Lion is an early 20th century painting by French Post-Impressionist Henri Rousseau. Done in oil on canvas, the work depicts a feeding lion in a jungle setting. The painting expands upon some of Rousseau's late 19th century work, and the foliage depicted in the painting was inspired by the artist's studying of Paris' botanical gardens. The work is currently on display at the Metropolitan Museum of Art.
