I'm hoping to get some feedback here on the
4:9 ratio,
not necessarily this image...

The Pythagorean ideas of ratios of small numbers were used
in the construction of the Temple of Athena Parthenos.
The ratio 2 : 3 and its square 4 : 9
were fundamental to the construction.
A basic rectangle of sides 4 : 9 was constructed from
three rectangles of sides 3 and 4 with diagonal 5.
This form of construction also meant that the 3 : 4 : 5
Pythagorean triangle could be used to good effect to ensure
that right angles in the building were accurately determined.

To a fairly high degree of accuracy this means
that the ratio width : length = 4 : 9 while
also the ratio height : width = 4 : 9.
