Ian Courtenay Johnston, An introduction to the work of Alfons Mucha and Art Nouveau (2014)
“ Even though the Art Nouveau style in architecture and painting points the way to the twentieth century, this is not where it belongs. Nor does it belong to the nineteenth century. Art Nouveau is an independent transitional phenomenon, a separate style which had deep roots in the nineteenth century as far as theory of art, art history, and the history of style are concerned, but whose entire aim was to shake off its stylistic heritage and create something completely new. Just as certainly as it had its roots in Historicism, so Art Nouveau foreshadowed the Modern Movement. ”
