Mondrian is another of my favourites and this piece in particular. It's so simple but has influenced generations of artists in all fields and there is something visually beautiful and captivating in its simplicity.
Piet Mondrian was a Dutch painter. His paintings are very famous all over the world. He contributed to the De Stijl art movement and he painted in a non-representational form which was called Neo-Plasticicm. This kind of art movement or form consisted of a white ground where a grid of vertical and horizontal black lines were painted and colored by the three primary colors.
