In this case the balance-center is indicated by a circle, which, being a curve, is in harmony of character with the inclosed line, which is also a curve. I shall call this Occult Balance to distinguish it from the unmistakable Balance of Symmetry and other comparatively obvious forms of Balance, including the balance of double inversions. As I have said, on [page 24], the symmetrical framing must be sufficiently attractive to hold the eye steadily at the center, otherwise it does not serve its purpose.
THE ORDER OF RHYTHM
IN LINES
76. The eye, not being held on a vertical axis or on a balance-center, readily follows any suggestion of movement.
Fig. 97
In this case there is no intimation of any vertical axis or balance-center. The figure is consequently unstable. There is a sense of movement to the right. This is due, not only to the inclinations to the right, but to the convergences in that direction.
Fig. 98
In this case the movement is unmistakably to the left. In such cases we have movement, but no Rhythm.
77. Rhythm requires, not only movement, but the order of regular and marked intervals.
