Art Nouveau - French for "The New Art." An art movement and style of decoration and architecture of the late nineteenth and early twentieth centuries, characterized particularly by the depiction of leaves and flowers in undulating lines, often flowing vines. Gustav Klimt (Austrian, 1862-1918), Alphonse Mucha (Czechoslovakian, 1860-1939), Henri de Toulouse-Lautrec (French, 1861-1901), Aubrey Beardsley (English, 1872-1898), Antonio Gaudí (Spanish, 1852-1926), and Hector Guimard (French, 1867-1942) were among the most prominent artists associated with this style. The roots of Art Nouveau go back to Romanticism, Symbolism, the English Arts and Crafts Movement and William Morris (English, 1834-1896). Art Nouveau is also known as Jugenstil and Yellow Book Style, epitomizing what is sometimes called fin de siècle style.

Stained Glass - The art of cutting colored glass into different shapes and fitting them into channeled lead strips, which are also called came. These are then soldered together, and usually installed in an iron framework to create a window.

Begun in Eastern Asia and among Muslim designers, the art of stained glass reached its height in the Middle Ages, particularly 1150-1250. As the solid Romanesque wall was eliminated, the use of glass could be and was expanded. Integrated with the lofty verticals of Gothic cathedrals, large windows afforded greater illumination that was regarded as symbolic of divine grace. These glaziers followed a cartoon to cut the glass, and fired the painted pieces in a kiln. Oxides fused with the molten glass to produce the intense colors of small pieces whose irregular surfaces created sparkling refractions of light. Outstanding examples of twelfth century stained glass can be found in the windows of such churches as Saint-Denis, in Paris, and Canterbury, in England. Among the finest thirteenth century works are the windows at Chartes and the Sainte-Chapelle in Paris.
