Post-Impressionism (1880-1910) marked a decisive turn away from Impressionism's focus on natural light and color. In its place, Post-Impressionist artists emphasized bold color, geometric forms, expressive distortion, and symbolic meaning. This course explores the movement through the work of Paul Cezanne, Vincent van Gogh, Paul Gauguin, Georges Seurat, and Henri Matisse. Although these artists did not form a unified group, they collectively redefined the artist's role and the function of art in society. By challenging industrial-era values, conventional artistic practices, and religious ideologies, Post-Impressionism laid the groundwork for the radical innovations of modern art.
