During 1962 and 1963, the American artist Robert Morris made an object called Location (Fig. 1). This is a wooden panel, featuring two tones of lavender-grey paint – a paler background shade overlayed with text and arrows in a slightly darker hue.1 The word ‘LOCATION’ appears across its centre and the arrows point towards its four edges. Each side bears the word ‘CEILING’, ‘FLOOR’, or ‘WALL’, emphasising its architectural environment. An alterable, numerical meter is also embedded into its surface at each edge, accompanied by the word ‘FEET’. These meters are all adjusted whenever Location is displayed to show the distance between the panel's edges and the limits of the room.
