As an example of how a style goes out of fashion, similar to the process ideas go through when they wear themselves out and need to be put to rest for awhile, look at these two works in glass. Both were produced soon after World War I and both were produced by Laliques - father and daughter. This perfume bottle (Flacon Fraicheur) that Rene Lalique designed in 1919 is of a familiar graceful example of his work in the style L'Art Nouveau, but it is overwrought. Pleasing to the eye perhaps, but it would be a pain in the neck to handle if it held your favorite perfume. The style has become the meaning, in this case trumping its ostensible purpose.
Now look at Tourbillon, (Whirlwind) by his daughter Suzanne Lalique-Haviland. A work created in the then ascendant style that had yet to be named - Art Deco. She shows a mastery of design elements that are abstract and self-consciously modern, conveying a sense of the chaotic movement suggested by the object's name, while respecting the integrity of the jar itself.
