Line








" . . . . ne pas prendre par la ligne, mais par le milieu," Eugène Delacroix wrote in his journal [Take hold of objects by their center, not by the lines of their apparent edges].


Perceiving Boundaries
Is the ability to understand drawings learned? Humans almost always appear to understand lines that represent the edges of surfaces. We also have no problem with a single line used to depict the parallel edges of a narrow object, such as a rope. One thing that we do not easily recognize is lines showing color boundaries on the surface of an object.

To illustrate the last point, let's pay a brief visit to the Songe, a small tribe in Papua New Guinea. Before they were tested, the Songe had never made or seen line drawings--not even doodles scratched on the ground. As a test, the Songe were shown drawings of a hand and a parrot. They easily recognized the hand and the parrot from simple outlines, but lines showing color boundaries confused them. The half-moons on the fingernails, for example, made them think that the nails had been damaged and new ones were growing in. Similarly they thought that the parrot must have been cut repeatedly. They thought this even though the lines in the drawing match color markings of parrots found in Songe territory (Kennedy, 1983). [Coon, Dennis.
