Impressionism is a 19th-century art movement characterized by relatively small, thin, yet visible brush strokes, open composition, emphasis on accurate depiction of light in its changing qualities (often accentuating the effects of the passage of time), ordinary subject matter, inclusion of movement as a crucial element of human perception and experience, and unusual visual angles. Impressionism originated with a group of Paris-based artists whose independent exhibitions brought them to prominence during the 1870s and 1880s.
The Impressionists faced harsh opposition from the conventional art community in France. The name of the style derives from the title of a Claude Monet work, Impression, soleil levant (Impression, Sunrise), which provoked the critic Louis Leroy to coin the term in a satirical review published in the Parisian newspaper Le Charivari.
The development of Impressionism in the visual arts was soon followed by analogous styles in other media that became known as impressionist music and impressionist literature.
Post-Impressionism (also spelled Postimpressionism) is 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. Due to its broad emphasis on abstract qualities or symbolic content, Post-Impressionism encompasses Les Nabis Neo-Impressionism, Symbolism, Cloisonnism, Pont-Aven School, and Synthetism, along with some later Impressionists' work. The movement was led by Paul Cézanne (known as father of Post-impressionism), Paul Gauguin, Vincent van Gogh, and Georges Seurat.
The term Post-Impressionism was first used by art critic Roger Fry in 1906.Critic Frank Rutter in a review of the Salon d'Automne published in Art News, 15 October 1910, described Othon Friesz as a "post-impressionist leader"; there was also an advert for the show The Post-Impressionists of France. Three weeks later, Roger Fry used the term again when he organized the 1910 exhibition, Manet and the Post-Impressionists, defining it as the development of French art since Manet.
Post-Impressionists extended Impressionism while rejecting its limitations: they continued using vivid colours, often thick application of paint, and real-life subject matter, but were more inclined to emphasize geometric forms, distort form for expressive effect, and use unnatural or arbitrary colour.
