A theory of pure design

by Denman Waldo Ross

Fig. 187

Here, for example, the movement of [Fig. 184] is facilitated and increased by a change of shape in the lines, lines with movement being substituted for lines which have no movement, beyond the movement of the convergence.

Fig. 188

In [Fig. 188] all the shapes have a downward movement which contradicts the upward movement of convergence. The movement down almost prevents the movement up.

112. The movement of any convergence may be straight, angular, or curved.

Fig. 189

In this case the movement of the convergence is angular. It should be observed that the movement is distributed in the measures of an arithmetical progression, so that we have, not only movement, but rhythm.
