Post-Impressionism is an art movement that emerged in the late 19th century, following Impressionism. Artists in this movement sought to express their emotions and ideas through bold colors, distinct brush strokes, and symbolic content, moving beyond the naturalistic depictions of their predecessors. Key figures of Post-Impressionism include Vincent van Gogh, Paul Cézanne, and Georges Seurat. Each artist brought a unique perspective, with van Gogh focusing on emotional intensity, Cézanne emphasizing geometric forms, and Seurat developing the technique of pointillism. This movement laid the groundwork for modern art by prioritizing personal expression over realistic representation.
