# Is Parthenon golden ratio?

## Is Parthenon golden ratio?

The Greek mathematician and sculptor Phidias used the golden ratio when designing the Parthenon, which still stands on the Athenian Acropolis in Greece [source: Horn]. For example, the Parthenon is 30.8 meters wide and 69.51 meters long (101 and 228 feet, respectively). This equals a 4:9 ratio.

What is the Greek golden ratio?

Two numbers are in the golden ratio if the ratio of the sum of the numbers (a+b) divided by the larger number (a) is equal to the ratio of the larger number divided by the smaller number (a/b). The golden ratio is about 1.618, and represented by the Greek letter phi, Φ.

### Did the Greeks know about the golden ratio?

As far as I am aware, there is actually no evidence that the Greeks even knew about the Golden Ratio at the time when the Parthenon was constructed at all. The Golden Ratio first began to be mythologized by the Italian Renaissance mathematician Luca Pacioli (lived c. 1447 – 1517), a friend of Leonardo da Vinci.

Where is the golden ratio in the Parthenon?

The height of the Parthenon, from the base of the second step to the top of its roof peak (projected lines), is a golden ratio to its width at the end of the entablature.

#### How is golden ratio used in architecture?

Ancient Greek architecture used the Golden Ratio to determine pleasing dimensional relationships between the width of a building and its height, the size of the portico and even the position of the columns supporting the structure. The final result is a building that feels entirely in proportion.

Who proved the golden ratio?

18th-century mathematicians Abraham de Moivre, Daniel Bernoulli, and Leonhard Euler used a golden ratio-based formula which finds the value of a Fibonacci number based on its placement in the sequence; in 1843, this was rediscovered by Jacques Philippe Marie Binet, for whom it was named “Binet’s formula”.

## How was the Parthenon an example of the golden section in architecture?

The Parthenon in Athens, built by the ancient Greeks from 447 to 438 BC, is regarded by many to illustrate the application of the Golden Ratio in design. The Parthenon was constructed using few straight or parallel lines to make it appear more visually pleasing, a brilliant feat of engineering.

Where does the golden ratio exist in architecture art?

The Acropolis of Athens (468–430 BC), including the Parthenon, according to some studies, has many proportions that approximate the golden ratio. Other scholars question whether the golden ratio was known to or used by Greek artists and architects as a principle of aesthetic proportion.

#### When was the Parthenon and Phi, the golden ratio built?

Original article follows: The Parthenon in Athens, built by the ancient Greeks from 447 to 438 BC, is regarded by many to illustrate the application of the Golden Ratio in design. Others, however, debate this and say that the Golden Ratio was not used in its design.

When was the golden ratio used in the pyramids?

Believed to have been constructed around 4,600 years ago, these pyramids were built around the golden ratio, long before the Greeks and the Parthenon. The largest of the pyramids in Giza contains the use of phi and the golden ratio.
