But the restlessness you can feel in Art Nouveau design - its famous "whiplash" line and proliferating tendrils - was not just a response to the sanguine energies of nature. It was also an outgrowth of the weird, unsettling riptides convulsing fin de siècle Europe. Drug use, morbidity, an intensely rarefied aestheticism, and highly charged, violently contradictory conceptions of women were all part of the mix.
Women, in the world of Art Nouveau, were either dreamy and pliant or sexually malevolent. They were never a civilizing force or agents of their own fate as they came to be conceived of by the designers of Art Deco. (Art Deco, of course, is usually seen as "masculine" and streamlined in opposition to Art Nouveau's softer, more "feminine" aesthetic; but in truth, it was the Art Deco period, after the slaughter of millions of young men in the Great War, that allowed women to come into their own.)
