What is the main characteristic of Art Nouveau?

Art Nouveau is primarily distinguished by its distinctive aesthetic that features flowing lines, flat shapes, and motifs inspired by the natural world. This artistic movement emerged in the late 19th and early 20th centuries, characterized by its organic forms and decorative elegance. Artists and designers sought to break away from traditional styles and instead adopted a more free-form approach that embraced the beauty found in nature, incorporating elements like flowers, leaves, and other natural shapes into their work.

The flowing lines often mimic the curves and shapes found in plants and flowers, creating a sense of harmony with the surrounding environment. The use of flat shapes also contributes to the overall decorative quality of Art Nouveau, as it blends functionality with art in a way that remains cohesive and visually appealing. This combination of characteristics is what defines the essence of Art Nouveau and sets it apart from other movements that may focus more on realism, classical influence, or abstract simplicity.
