A leading figure in American minimalism, Donald Judd established an essential vocabulary of forms and remained faithful to it. Judd constructed “specific objects”, as he called them, using simple and often repeated forms as a way of exploring space and its uses. Untitled, from 1984, it is one of these constructions. Made from steel, it is an exploration of simple geometric advancing progressively into space. As in some of his other primary structures, Judd eschews illusionism and the representation of space found in the European artistic tradition, rather allowing scale, materials and the evolution of the line to become an end in themselves. The artist refuses to call his works “sculptures”, insisting on their industrial, radically depersonalised fabrication.
