Art Deco vs Art Nouveau
アール・デコ / アール・ヌーヴォー
Both fill the frame with ornament and put stylized plants and female figures in the lead, as European decorative styles applied to everything.
How to tell them apart. Look at the outline of the ornament. Art Nouveau runs one asymmetric curve that never repeats, while Art Deco repeats straight edges and fans in mirror symmetry.
Art Deco
Stages urban luxury with repeating geometry and a metallic sheen.
Art Nouveau
Joins letters, figures and ornament into one flowing, plant-like line.
