Parthenon Golden Ratio Math

So between disney s donald in mathmagic land and my articles listed above we find evidence that appears to substantiate the application of golden ratios in the following design elements of the parthenon.

Parthenon golden ratio math. The photo below illustrates how this section of the parthenon would have been constructed if other common ratios of 2 3 s or 3 5 s had been intended to be represented by its designers rather than the golden ratio. This number is represented by phi the 21st letter of the greek alphabet. A greek scholar named pythagoras who lived in the 5th century b c e has often been credited with discovering one of history s most enduring mathematical concepts. It s also been called the golden mean the golden section or the divine proportion depending on who is using the term.

As a quick background the golden ratio is defined by dividing a line at the one point at which the ratio of the larger segment a to the small segment b is equal to the ratio of the line a b to the larger segment a. Using that approach there is then another golden ratio from the bottom of the second step to the top of the columns to the top of the roof. This probably more than any other single feature of the parthenon provides rather compelling evidence that the greeks knew of and applied the golden ratio in the construction of the parthenon.
