Read the excerpt from A Short Walk Around the Pyramids and through the World of Art.

The Parthenon.

Parthenon, high on a hill, catches the first light of morning. The carvers wanted the sight of that golden light washing across the horse and a line of other gods to be unforgettable. And so they coaxed the images of their gods out of the marble with such tenderness that they gave the world an example of ideal beauty. Each figure is as calm and as refined as our minds can imagine. They are so noble and quiet that they do seem godly and perfect companions for the noble, quiet temple.
