Wall Drawing 957, first executed in 2000 at the Whitney Museum of American Art, presents two isometric forms derived from a cube. These forms are rendered isometrically, a method that Sol LeWitt first began to experiment with in the early 1980s. Angled toward the viewer, the irregular cubic forms imply volume but do not suggest any kind of spatial recession, maintaining the two-dimensionality of the wall’s flat surface plane. Drawn in black pencil, Wall Drawing 957 employs the four basic directions of line – horizontal, vertical, diagonal left, and diagonal right. The four absolute lines are superimposed sequentially, depicting their single, double, triple, and quadruple combinations, thus resulting in four degrees of density that delineate the planes of the cubic forms.
