The first, wooden, version of this sculpture was lost during the Second World War. Moore made a modified version in plaster in 1960 and cast it in bronze. In his use of strings in this and other sculptures of 1937-9 Moore was influenced by Naum Gabo's interest in articulating space. However, this practice is also an extension of Moore's interest in the intersection of space and solid as exemplified by pierced forms. Writing in 'Circle' the scientist J. D. Bernal stated that 'Negative curvature ... is characteristic of much modern work, as are subtle inflections and the use of nodal points.' This sculpture suggests, in an abstract way, a reclining female figure.
