The ancient Greeks, Romans, Egyptians, and many other civilizations knew about the golden ratio. They called it by different names, but they all saw this particular ratio as very pleasing and designed architecture that utilized it. The Parthenon, which the Greeks constructed, has the golden ratio present in many different places. The ratioof the width to the height of the building and the ratioof the height of the building to the height of the roof are both golden. Plus, the pillars in the front are placed so that the width of the building is split into a golden segment. The Egyptians used the golden ratio to construct the Pyramids of Giza. The ratioof the side length of the pyramid to half the length of the base is, you guessed it, the golden ratio.
