Best known for his mobiles, Alexander Calder conceived of sculptures as an experiment in space and motion. Over the course of his prolific career, Calder developed works ranging from large-scale, colorful, and dramatic standing sculptures to miniature, delicate, and more figurative objects that perched on tabletops. Untitled (1954) is a beautiful example of his preoccupation with elemental systems. Comprising of three balanced discs, the sculpture is extremely suggestive of movement. Arranged with wire bent into formation, the discs appear to levitate, evoking volume without the accompanying mass. As written by curator Cara Manes, "Uniting all of Calder's works is a dependence on a viewer's perception of their many elements to achieve their full expression: they contain infinite forms, none of them final."
