This monumental, richly illustrated volume from ZKM | Karlsruhe approaches modern sculpture from a spatial perspective, interpreting it though contour, emptiness, and levitation rather than the conventional categories of unbroken volume, mass, and gravity. It examines works by dozens of twentieth- and twenty-first-century artists, including Hans Arp, Marcel Duchamp, Henry Moore, Barbara Hepworth, Lygia Clark, Anish Kapoor, Olafur Eliasson, Ana Mendieta, Fujiko Nakaya, Tomas Saraceno, and Alicja Kwade. The large-scale book contains over 800 color images.
