Successive Golden Rectangles dividing a Golden Rectangle into squares (logarithmic spiral known as the golden spiral)


The Battle of San Romano c. 1435–1455), Galleria degli Uffizi, Florence
The Battle of San Romano is a set of three paintings by the Florentine painter Paolo Uccello depicting events that took place at the Battle of San Romano between Florentine and Sienese forces in 1432. They are significant as revealing the development of linear perspective in early Italian Renaissance painting, and are unusual as a major secular commission.

They are now divided between three collections, the National Gallery, the Galleria degli Uffizi, Florence, and the Musée du Louvre, Paris. Source: Wikipedia: The Battle of San Romano.

Paolo Uccello
Paolo Uccello (1397 – 1475) was an Italian painter and a mathematician who was notable for his pioneering work on visual perspective in art. Read more.

Golden rectangle
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.

Droste Effect
The Droste effect is a specific kind of recursive picture, one that in heraldry is termed mise en abyme. An image exhibiting the Droste effect depicts a smaller version of itself in a place where a similar picture would realistically be expected to appear. This smaller version then depicts an even smaller version of itself in the same place, and so on. Only in theory could this go on forever; practically, it continues only as long as the resolution of the picture allows, which is relatively short, since each iteration geometrically reduces the picture's size. It is a visual example of a strange loop, a self-referential system of instancing which is the cornerstone of fractal geometry. Source: Wikipedia, Droste Effect.
