Sculpting Time explores time as a medium in Calder’s work: both as an integral part of his kinetic sculpture and as an external factor vis-à-vis the grand developments of the 20th century. This is best exemplified in his earliest sphériques as well as the Constellations (a term coined by Marcel Duchamp and James Johnson Sweeney in 1943) he created out of wood and wire during World War II, when sheet metal was not available. By introducing motion into a static art form, Calder implies the passage of time; thus, time also sculpts. This handsome clothbound volume, printed on Tatami paper, is filled with contemporary images of works from the 1930s to the 1970s, as well as archival photographs of Calder’s studio.
