An art movement is a tendency or style in art with a specific common philosophy or goal, followed by a group of artists during a specific period of time, (usually a few months, years or decades) or, at least, with the heyday of the movement defined within a number of years. Art movements were especially important in modern art, when each consecutive movement was considered a new avant-garde movement. Western art had been, from the Renaissance up to the middle of the 19th century, underpinned by the logic of perspective and an attempt to reproduce an illusion of visible reality (figurative art).
Post-Impressionism (also spelled Postimpressionism) was a predominantly French art movement that developed roughly between 1886 and 1905, from the last Impressionist exhibition to the birth of Fauvism. Post-Impressionism emerged as a reaction against Impressionists' concern for the naturalistic depiction of light and colour. Its broad emphasis on abstract qualities or symbolic content means Post-Impressionism encompasses Les Nabis, Neo-Impressionism, Symbolism, Cloisonnism, the Pont-Aven School, and Synthetism, along with some later Impressionists' work.
Neo-Impressionism is a term coined by French art critic Félix Fénéon in 1886 to describe an art movement founded by Georges Seurat. Seurat's most renowned masterpiece, A Sunday Afternoon on the Island of La Grande Jatte, marked the beginning of this movement when it first made its appearance at an exhibition of the Société des Artistes Indépendants (Salon des Indépendants) in Paris. Around this time, the peak of France's modern era emerged and many painters were in search of new methods.
Modern art includes artistic work produced during the period extending roughly from the 1860s to the 1970s, and denotes the styles and philosophies of the art produced during that era. The term is usually associated with art in which the traditions of the past have been thrown aside in a spirit of experimentation. Modern artists experimented with new ways of seeing and with fresh ideas about the nature of materials and functions of art. A tendency away from the narrative, which was characteristic of the traditional arts, toward abstraction is characteristic of much modern art.
An art exhibition is traditionally the space in which art objects (in the most general sense) meet an audience. The exhibit is universally understood to be for some temporary period unless, as is occasionally true, it is stated to be a "permanent exhibition". In American English, they may be called "exhibit", "exposition" (the French word) or "show". In UK English, they are always called "exhibitions" or "shows", and an individual item in the show is an "exhibit".
