Piet Mondrian (1872–1944) was a Dutch painter and co-founder of De Stijl, whose iconic grid paintings of black lines and primary colours represent his theory of Neo-Plasticism — the search for universal harmony through pure formal elements. Beginning as a landscape painter, he progressively stripped his work of representation, arriving at the radical geometrical abstractions for which he is celebrated. His austere, rigorous works are among the most influential in the history of abstract art, shaping graphic design, architecture, and modernist aesthetics worldwide. Mondrian's prints work beautifully in minimalist, modern interiors seeking clarity and intellectual elegance.
