Piette mondriaan (English: Piet Cornelies Mondrian,1872 march 7-1944 January1), a Dutch painter, is one of the behind-the-scenes artists of the German de stijl movement and one of the founders of non-figurative painting, which has had a great influence on the architecture and design of later generations.

Mondriaan is a pioneer of geometric abstract painting school. He took geometric figure as the basic element of painting, founded "de stijl" with Texaco and others, and advocated his own artistic "New Modelism". He also believes that art should be fundamentally divorced from the external form of nature, with the purpose of expressing abstract spirit and pursuing the absolute realm of the unity of man and God, which is now called "pure abstraction".
