Hepworth wrote in 1952 that she became "absorbed in the relationships in space, in size and texture and weight, as well as the tensions between forms".
The work consists of three rounded elements positioned on a flat rectangular base, all in polished Seravezza marble (largely white, but small brown marks, grey flecks, and pale grey graining are visible on close inspection).
The original base has been replaced, but the spatial arrangement of each element remains the same, with a spherical element placed at a distance from two larger and elongated oval forms, the smaller of which lies flat and the larger of which rests on its long edge, both aligned with the longer edge of the rectangular base.
Hepworth later accepted criticism from physicist John Desmond Bernal that the elements are all positively curved, and suggested that the work could have been improved by the sphere being replaced by a cylinder.
It was bought from Hepworth by Mr and Mrs JR Marcus Brumwell in late 1935, and they donated it to the Tate Gallery in 1964.
