Emphasizing geometry and repetitive patterns in his work, Sol LeWitt brought recognition to the Conceptual Art movement in the 1960s. Over the following years his art became both increasingly complex and increasingly playful, and around 1980 he began to incorporate bright colors in his wall drawings. As is typical of LeWitt’s work, a group of assistants executed this piece, guided by precise written instructions and diagrams from LeWitt, who wrote that the artist’s idea “becomes a machine that makes the art.” Although conceptual artists generally deemphasize the appearance of a work of art, instead highlighting the ideas that determine its form, LeWitt’s wall drawings are both conceptually drivenand visually appealing, even decorative. © 2009 The LeWitt Estate / Artists Rights Society (ARS), New York
