Adolf Luther * (Uerdingen 1912–1990 Krefeld) Concave mirror object, 1985, signed, dated on the reverse Luther 85 and stamped in red ENERGETISCHE PLASTIK, 36 x 2 rectangular concave mirrors on spacer mounted on black wooden board, 220 x 26.5 x 8 cm, in original plexiglass box Provenance: Private Collection, North Rhine-Westphalia Exhibited: Galerie Neher, Essen (gallery label) “Every concave mirror object is first and foremost an instrument. It faces the room in front of it, which it both reflects and optically dynamises. The function of the many identical concave mirrors is indeed twofold. On the one hand, they optically multiply a given reality into a multitude of distorted and abstract ornamental appearances, likely to irritate the viewer. On the other, they create a kind of pure phenomenality within the space, thereby transforming the space itself into an otherwise invisible, light-flooded realm of energy.” (Max Imdahl, Erläuterungen zur Modernen Kunst, Düsseldorf 1992, p. 155)
