Final answer:
While the 'Ant Chair' and 'Tulip Chair' represent modern design principles, they do not directly relate to Surrealism or De Stijl. Instead, these chairs illustrate the evolution of design from organic Art Nouveau forms to the sleek, minimalistic features of mid-century modern designs.
Step-by-step explanation:
The Art Nouveau style is exemplified by the chair designed by Henry van de Velde in 1895, which showcases organic, stylized lines and a curvilinear form similar to that of Tiffany glass. On the other hand, the 'Ant Chair' created in 1952 by Arne Jacobsen illustrates a modern design, with its functional form, tubular steel legs, and laminated wood veneer shaped like an ant. These two pieces do not point to either De Stijl or Surrealism but to different artistic movements that emphasize organic forms and modernism.
Furthermore, Eero Saarinen's 'Tulip Chair' is iconic for its space age design, utilizing curved lines and artificial materials to simplify form. Comparatively, a staircase made in the Shaker style, with an organic spiral taking on the 'golden ratio', reflects a different aesthetic that also emphasizes simplicity and functionality. It's important to note that while Surrealism drew on Freudian theory, De Stijl looked more towards minimalist and abstract expressions away from psychological symbolism.
In the context of design, the 'Ant Chair' and the 'Tulip Chair' are more emblematic of Scandinavian modernism and mid-century modern design, respectively, rather than Surrealism or De Stijl.
