A quintessential example of Jan Schoonhoven's systematic exploration of light and shadow, this 1969 relief work features a grid-like arrangement of precisely constructed geometric forms that create subtle gradations across its surface. The work exemplifies the Dutch artist's association with the Nul movement, emphasizing repetition, neutrality, and the quiet drama of light playing across uniform, repeated shapes. Schoonhoven's meticulous hand-crafted construction results in a meditative, almost monochromatic composition that challenges the boundary between painting and sculpture.
