A man stone deaf can enjoy watching a dance. He has never heard a sound in his life, but his sense of sight is stirred to pleasure by the spectacle of measured repetition of the movements. Similarly, the measured repetitions of stationary objects gives us pleasure,--the measured repetition, for example, presented by the West Point cadets, as they suddenly halt, either in close formation or in open ranks. “How beautiful!” we exclaim. And it is because the Athenians realized the beauty of measured repetition and the pleasure that it gives to the sense of sight, that they surrounded their great temple, the _Parthenon_, with ranks of columns, arranged at equal distance from one another. For, though they may have learned the beauty of repetition from studying the tree stems in the woods, yet, when they built their work of art, they avoided the haphazard of nature, and introduced order and arrangement by making the repetitions measured.
