Fibonacci’s Hidden Code: Uncovering the Mathematics Behind Classical Art | The Fusioneer (2024)

Posted on November 27, 2023 in Art History

In the realm of art, beauty often hides a secret, and the world of mathematics can be an unassuming yet powerful accomplice. If you’re a regular follower of Paul Kirby & robot painter Dulcinea’s art, the fusion of art and science is something you’re well aware of — but did you know that the classical artistic masters were just as concerned with blending disciplines?

Classical art, with its captivating compositions and harmonious proportions, frequently conceals the heavy influence of mathematical principles on its design. One of the most ubiquitous and intriguing connections is that of the Fibonacci sequence, a numerical pattern that has woven itself into the fabric of many renowned artworks.

What is the Fibonacci Sequence?

The Fibonacci sequence, or Fibonacci Series, is a series of numbers where each number is the sum of the two preceding ones: 0, 1, 1, 2, 3, 5, 8, 13, 21, and so on. This sequence has an uncanny ability to appear in various aspects of nature, from the arrangement of leaves on a stem to the spirals of a seashell. Its prevalence extends to the world of art, where its mathematical elegance infuses compositions with an inherent sense of harmony.

When Was It Discovered?

The Fibonacci numbers were known as early as 200 BC and were described in Indian mathematics by Acharya Pingala, an ancient Indian poet and mathematician. The numbers are now known by the name Fibonacci, an alias of Italian mathematician Leonardo of Pisa, the man who introduced the sequence to the Western world in 1202.

The Golden Ratio: Aesthetic Perfection

The Fibonacci sequence’s most famous offspring is the “golden ratio,” also known as the divine proportion or phi (Φ). This ratio (approximately 1.61803398875) is derived by dividing any number in the Fibonacci sequence by the number that precedes it. The resulting ratio is an aesthetically pleasing proportion that, for some reason — perhaps its prevalence in nature — looks ideal to the human eye.

The golden ratio would go on to become one of the most widely-used and important mathematical concepts of all time, being employed in disciplines from mathematics, physics, painting, architecture, music, and so much more. The golden ratio has even more benefits beyond visual allure, as when it is used in architecture it actually plays a role in the stability of a structure.

Fibonacci Spirals

One of the most visually captivating manifestations of the Fibonacci sequence is the Fibonacci spiral, also known as a golden spiral in geometry. This spiral is created by drawing arcs inside squares whose side lengths correspond to Fibonacci numbers. The result is a gracefully expanding spiral that can be observed in nautilus shells, hurricanes, and even galaxies. In classical art, this spiral’s proportions are often used to guide the placement of elements within a composition, leading the viewer’s gaze along an aesthetically pleasing path.

The Fibonacci Sequence in Art

Artists throughout history, knowingly or unknowingly, have integrated the Fibonacci sequence into their works. Paintings, sculptures, and even musical compositions exhibit elements of this sequence, enriching the creative process with a hidden mathematical symphony. The orchestration of Fibonacci-related proportions in art resonates with the innate mathematical inclinations of human perception, captivating audiences on a subconscious level.

Here are but a few of the myriad examples of the Fibonacci sequence and the golden ratio being utilized by artists:

• Leonardo da Vinci
  Leonardo’s Vitruvian Man famously demonstrates the golden ratio’s influence on human proportions.
• Michelangelo
  The proportions of the Sistine Chapel’s ceiling are believed to be influenced by the golden ratio.
• Salvador Dali
  Dali’s The Sacrament of the Last Supper features a dodecahedron (a shape related to the golden ratio) suspended above Jesus.
• Georges Seurat
  Seurat’s A Sunday on La Grande Jette is thought to incorporate golden ratio proportions in its composition.
• The Parthenon (Ancient Greek Architecture)
  The Parthenon’s columns and overall structure exhibit the golden ratio’s influence.
• The Great Pyramid of Giza (Ancient Egyptian Architecture)
  The dimensions of the Great Pyramid are believed to relate to the golden ratio.
• Spiral Staircases
  Some spiral staircases, like those in the Vatican Museums, incorporate Fibonacci spirals.

Search for the Hidden Code Yourself

As we discover the power of the Fibonacci sequence, its uses, and its prevalence, we come to appreciate the symphony of numbers that elevates art beyond the canvas, into a realm where aesthetics and mathematics harmonize in exquisite brilliance. If you weren’t aware of the Fibonacci sequence or the golden ratio in art before, it will now feel as though you’ve been initiated into a new level of awareness. You’ll start seeing it everywhere, both in the natural world and in the human-made designs all around you.
