like many of LeWitt's later works, makes use of a wider variety of forms and colors. Perhaps influenced by his move to Italy, the colored washes lend #439 a frescoed effect. LeWitt's skillful use of the rich, variegated colors arranged in a fan-like cluster of cascading triangles provides the illusion of three-dimensionality. In a sense, LeWitt returned to the point in the development of artistic production when the artist's (and viewer's) eye was the only tool required to promote the illusion of depth and wholeness on a flat plane.
