A key member of the Light and Space movement in Los Angeles during the 1960s and 1970s, De Wain Valentine (born 1936) is distinguished by his in-depth understanding of synthetic materials and his ability to transform industrial products into artworks that investigate the seductive power of light, transparency, reflection and surface. Published for his critically lauded 2015 exhibition at David Zwirner, New York, Works from the 1960s and 1970s focuses on the artist's pioneering achievements in polyester resin and features new scholarship by Robin Clark. It includes color plates of Valentine's Columns, corporeally scaled sculptures cast in colored polyester resins that recede from a wider base up to a narrow tip; his Circles, six-foot discs that display his mastery of geometrical form and his command of color; and a selection of his smaller forms--rings, discs and double pyramids. The catalogue also features extensive documentation of Double Column Gray (1975-76), two massive, identical 12-foot columns.
