The Art Nouveau style occurred during the last quarter of the 19th century and evolved from Aestheticism followed by the Art and Crafts Movement.
The revolution occurred because many artists and designers were disenchanted and bored with the fussiness of Victorian art, design, style and fashion.
New design and style ideas appeared in many different areas of Victorian life, and designers continued to search for ways to reflect the changing world of the late 19th century. In Britain, in the last quarter of the century, international trade was more important than it had ever been. At the same time, there was a consciousness, particularly among artists and designers, that this was a new, modern age which should be reflected in their work; they needed a 'new art' or, as the French say, "Art Nouveau."
This was not a purely British movement but was seen worldwide in Europe, Australia, the USA, Canada and Japan.
Art Nouveau was a conscious attempt at modernism and a departure from traditional Victorian forms of design, most of which looked back to the past for inspiration.
Designers rejected the inspiration of classical European art and instead looked to Japanese, Celtic and other folk art as a basis for their work. This can be seen in works by artists such as Gustav Klimt. Typical motifs come from nature: flowers, insects and birds. Lines curve and wind, straight lines were scorned by Art Nouveau designers.
Symbolism is important in the designs. For example a leaf may be just a leaf or perhaps it is part of the female body. Designers used forms from the natural world in ways that suggested they might represent human limbs. They used traditional materials like wood, glass, and pewter.
I love the organic shapes and design features.
I admire these artists and architects for the way they shook up the established order and forged ahead with something so different
