Art nouveau, emerging at the end of the 19th century, is an influential artistic movement characterized by its organic aesthetics and sinuous lines. Drawing inspiration from nature, it manifests in architecture, decorative arts, and fine arts. Figures such as architect Hector Guimard and artist Alfons Mucha contributed to creating works adorned with floral motifs and elegant curves. The movement aims to merge art with everyday life, featuring patterns inspired by flora and flowing forms. Although its peak was relatively short-lived, its influence endures in iconic works such as the Parisian metro entrances and creations by the École de Nancy.
