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