The phrase "untutored genius who created a paradise" refers to Ferdinand Cheval, a French postman who single-handedly constructed Le Palais Idéal (The Ideal Palace) in Hauterives, France.

Nature of Contribution to Art:

• Outsider Art: Cheval's work is considered a prime example of Outsider Art (Tate), also known as Art Brut. This category encompasses art created by self-taught or visionary individuals who are outside the mainstream art world.
• Architectural Sculpture: Le Palais Idéal is a unique blend of architecture and sculpture. Cheval incorporated diverse styles inspired by postcards and illustrated magazines, creating a fantastical and elaborate structure.
• Persistence and Vision: Cheval's dedication is a significant part of his artistic contribution. He spent 33 years, from 1879 to 1912, collecting stones and building his palace. The official website (facteurcheval.com) notes he carried stones at night during his postal route.
• Inspiration to Others: Cheval's Palais Idéal has inspired artists and writers, influencing Surrealism and Naive art.

In summary, Ferdinand Cheval's contribution lies in his creation of a unique architectural marvel through unwavering personal vision and dedication, making him a notable figure in Outsider Art.
