In his artistic efforts to visualize the invisible and to grasp a reality that eludes a pictorial representation Adolf Luther is one of the main representatives of Kinetic and Optical Art. Mirrors and glass are key materials in his quest for a visualization ofenergy in form of light. In the1960s he made light traps, works with"optic media", as well as works with concave mirrors and first "spherical objects", which he contributed to "Zero" exhibitions in Berlin, Frankfurt, Gelsenkirchen and Philadelphia. In our mirror object from 1986 some 196 small concave mirrors are arranged in a strictly linear serial order and form, owed to their exact order and alignment, a large concave mirror surface. Depending on light incidence and the observer‘s perspective, a varying, artistically manipulated image of our reality is created. This way our conventional habits of seeing and perceptions of reality are challenged. Luther, the master of light art who had dedicated his artistic oeuvre to the interrelationship of light matter since the 1960s, attains the disengagement of visual sensation and matter in this work.
