The golden ratio: an ancient harmony at the heart of creation
The golden ratio has always intrigued us: this mathematical proportion, symbolized by the Greek letter Phi (φ), equals 1.618. Behind this value lies an omnipresence in nature, sacred architecture and art.
An ancient and sacred origin
The origins of the golden ratio date back to ancient Greece. The mathematician Euclid wrote about it in his Elements around 300 BC, describing it as a division "in extreme and medium reason", a perfect proportion between two lengths.
But long before the Greeks, the Egyptians would have used it, in the proportions of the Cheops pyramid.
A universal balancing formula
Mathematically, the golden ratio is the positive solution to the equation :
x² - x - 1 = 0or x = (1 + √5) / 2 ≈ 1,6180339887...
This proportion gives rise to a well-known sequence: the Fibonacci sequence, in which each term is the sum of the two preceding ones.
The further along you go, the more the ratio between two successive terms tends towards φ.
From the spiral of a shell to distant galaxies, from the veins of a leaf to human faces, the golden ratio is found everywhere. It seems to be a silent language of nature.
From the Renaissance to the present day: a timeless aesthetic
During the Renaissance, artists such as Leonardo da Vinci rediscovered the golden ratio. In Vitruvian Man, he explored the ideal proportions of the human body, directly related to φ. At Phi 1.618, we place the golden ratio at the heart of our creations.
Mystery or secret?
The golden ratio remains a subject of fascination and debate. Its presence in nature and its use by artists over the centuries lend it an aura of mystery and secrecy.
