This is an extract from a new exhibition at the Tate modern entitled Forms of Life. It features two artists - Hilma AF Klint (1862-1944) and Piet Mondrian (1872-1944). They both began as academically trained landscape artists and then developed a more radical approach to painting in the 20th cent. I had come to the exhibition to see Mondrian's work and his development. I have seen versions of his abstract paintings used many times in design from fabrics to architecture. I have posted some of his work here in chronological order.
