It has been hypothesized and exhaustively documented that the ancients were adept at the art of proportion and harmony and reflected this knowledge in their everyday life including their architecture.
The extensive surveying and documentation of the Temple of Luxor in Egypt by Schwaller de Lubicz merely scratched the surface of the exhibition of this science with a decade and a half of tireless archaeological work.
The basic important principle is that architecture is music. Whether an off key doghouse or a full blown Chartres Cathedral messianic requiem the medium is the same. Architectural music differs only in that it is heard with our eyes and sensed with our body.
There are certain rules that musicians follow to allow them to compose harmonious pieces of music such as octaves and harmonic fifths. In fact if someone was familiar with these rules they could compose music without the ability to hear as was proven with Beethoven. These same rules of harmony and geometric ratio governed ancient architecture.
By using harmonic ratios and balanced proportions we compose what is known as frozen music in form.
