there are lines in the picture, which do not define physical, concrete
objects. Curved lines around arms and legs are free form. Their shapes are
spontaneous. These are expressive lines, the second style of line. Rather
than defining objects, they express movement, elation, and air currents. Lines
around the human arms and legs suggest movement. Lines in front of the dog’s
mouth suggest noise. Such lines are not bound by the naturalistic rules of disegno
esterno. They are neither analytic nor do they define physical objects.
