**Golden Ratio in Architecture**

**1. The Great
Pyramid**

The Ahmes papyrus of Egypt gives an account of the building of the
Great Pyramid of Giaz in 4700 B.C. with proportions according to a “sacred
ratio.”

If we take a cross-section through a pyramid we get a triangle. The
Great Pyramid is called Egyptian Triangle, the Triangle of Price, or the
Kepler triangle. This triangle supposedly contains the golden
ratio. In particular, the ratio of the slant height to half the base is
said to be the golden ratio. If we compute the value for the sides of the
Egyptian triangle, their ratio is 1 : sqrt(Phi) : Phi

But, it is hard to know that the golden ratio was intentionally built
into the Great Pyramid or other architecture.

**2. Parthenon**

The Greek sculptor Phidias sculpted many things including the bands
of sculpture that run above the columns of the Parthenon.

Even from the time of the Greeks, a rectangle whose sides are in the
"golden proportion" has been known since it occurs naturally in some of
the proportions of the Five Platonic. This rectangle is supposed to appear
in many of the proportions of that famous ancient Greek temple in the Acropolis
in Athens, Greece.

**3. Porch
of Maidens, Acropolis, Athens**

**4.Chartres
Catehdralo**

The Medieval builders of churches and cathedrals approached the design
of their buildings in much the same way as the Greeks. They tried to connect
geometry and art.

Inside and out, their building were intricate construction based on
the golden section.

**5. Le
Corbussier**

In 1950, the architect Le Corbussier published a book entitled "Le modulator.
Essai

sur une mesure harmonique a l'echelle humaine applicable universalement
a l'architecture et a la mecanique ". He invented the word "modulator"
by combining "modul" (ratio) and "or" (gold); another expression for the
well-known golden ratio.
