Axis
Any symmetrical or near-symmetrical volume has one or more axes which can be roughly described as
imaginary centre lines to which all parts of the volume may be related. Each volume of a sculptural
composition enters into axial relations with the others, and the direction of the axis of each volume
determines the direction of the volume. The concept of an axis applies not only to single volumes but
also to symmetrical or near-symmetrical groups of volumes. The movements of the volumes of the figure
in relation to the verticals may tilt out of the vertical in any direction or they may rotate around
the axis.
