Final answer:
Gauguin's primitivism was inspired by 'primitive' cultures and aimed to convey an essential truth through his technique. It functioned as a critique of modernity by challenging Western artistic conventions.
Step-by-step explanation:
Gauguin's primitivism stemmed from his fascination with the simplicity and power of styles found in 'primitive' cultures. He was inspired by the indigenous art of Tahiti and the French Polynesian islands, where he painted scenes with concepts influenced by both Western and Eastern sources. Through his technique, Gauguin aimed to convey an essential or spiritual truth in his subjects by using color, distorted form, and perspective.
Gauguin's primitivism functioned as a critique of modernity by challenging the dominance of Western artistic conventions and Eurocentric viewpoints. By exploring the visual forms and symbolism of non-Western or prehistoric cultures, Gauguin offered an alternative to the mainstream art of his time, which often focused on realism and naturalism.
