Post-impressionism is an art movement that emerged in the late 19th century, following the Impressionism movement. Artists sought to express their emotions and ideas through bold colors, distinct brush strokes, and innovative compositions. Unlike Impressionist artists, who focused on capturing light and everyday scenes, post-impressionists emphasized personal expression and symbolic content. Key figures of post-impressionism include Vincent van Gogh, Paul Cézanne, and Georges Seurat. Each artist developed unique styles, with van Gogh known for his swirling brushwork, Cézanne for his geometric forms, and Seurat for his pointillism technique. This movement laid the groundwork for modern art by encouraging individual interpretation and experimentation.
