Something I have been curious about: The relationship of my photography and the Golden Ratio or Fibonacci Spiral. I have never studied about this and just decided to overlay the Spiral on some of my images…surprising the result!

Artists:
Salvador Dalí explicitly used the golden ratio in his masterpiece, The Sacrament of the Last Supper. The dimensions of the canvas are a golden rectangle. A huge dodecahedron, with edges in golden ratio to one another, is suspended above and behind Jesus and dominates the composition.

Mondrian used the golden section extensively in his geometrical paintings.

History:
The modern history of the golden ratio starts with Luca Pacioli’s Divina Proportione of 1509, which captured the imagination of artists, architects, scientists, and mystics with the properties, mathematical and otherwise, of the golden ratio. Beginning in the Renaissance, a body of literature on the aesthetics of the golden ratio has developed. As a result, architects, artists, book designers, and others have been encouraged to use the golden ratio in the dimensional relationships of their works.

The first and most influential of these was De Divina Proportione by Luca Pacioli, a three-volume work published in 1509. Pacioli, a Franciscan friar, was known mostly as a mathematician, but he was also trained and keenly interested in art. De Divina Proportione explored the mathematics of the golden ratio. Though it is often said that Pacioli advocated the golden ratio’s application to yield pleasing, harmonious proportions, Livio points out that that interpretation has been traced to an error in 1799, and that Pacioli actually advocated the Vitruvian system of rational proportions. Pacioli also saw Catholic religious significance in the ratio, which led to his work’s title. Containing illustrations of regular solids by Leonardo Da Vinci, Pacioli’s longtime friend and collaborator, De Divina Proportione was a major influence on generations of artists and architects alike.

In geometry, a golden spiral is a logarithmic spiral whose growth factor b is related to ?, the golden ratio.[1] Specifically, a golden spiral gets wider (or further from its origin) by a factor of ? for every quarter turn it makes.
