The late 1960s and early 70s marked a career turning point for the late Rosemary Mayer. At that time her mostly conceptual works—drawings and abstract studies of color—mutated into sculpture. Experimenting with fabric, rods, and cords, Mayer creating flowing, delicate forms. “Like liquids and natural phenomenons,” Mayer wrote in 1973, “fabric too is subject to gravity and natural forces. . . . Like waves in water or leaves on trees.” The first Mayer retrospective in Europe includes the drawings and sketches that led to her creations. —E.C.
