Piet Mondrian, Lozenge Composition with Red, Black, Blue, and Yellow 1925 and Golden Rectangles

Piet Mondrian (March 7, 1872 - February 1, 1944) was a Dutch painter, pioneer of Geometric abstraction. He was an important contributor to the De Stijl art movement and group, which was founded by Theo van Doesburg. He evolved a non-representational form which he termed Neo-Plasticism. This consisted of a grid of vertical and horizontal black lines and the use of the three primary colors.

A golden rectangle is a rectangle whose side lengths are in the golden ratio, one-to-phi, that is, approximately 1:1.618. A distinctive feature of this shape is that when a square section is removed, the remainder is another golden rectangle, that is, with the same proportions as the first. Square removal can be repeated infinitely, which leads to an approximation of the golden or Fibonacci spiral. Post a comment.
