Symbolism and Art Nouveau emerged in the late 19th century as reactions against prevailing artistic movements. Symbolism rejected realism, focusing on emotions and hidden meanings through symbols and metaphors. Art Nouveau sought to create a modern style integrating art and craftsmanship, drawing inspiration from nature. Both movements emphasized personal expression and imagination, exploring themes of mystery and fantasy. Symbolist artists like Gustave Moreau and Odilon Redon created dreamlike works, while Art Nouveau pioneers such as Gustav Klimt and Alphonse Mucha produced ornate, flowing designs across various media.
