In the glass and mirror objects conceived as series, Adolf Luther thematizes immaterial light as an energetic reality in space. This insight precedes his painterly work: early impressionist paintings culminated in the "Black Matter Works," in which he overcomes illusionist categories.
In the 1980s, the hanging lenses were located on Hoeschplatz in front of the museum. Here they were brought to life by the weather and reflected the light into the surrounding space in ever-changing scenarios.
Today, the lenses are permanently installed in front of the Schoeller Hall in the atrium of the LHM and impress with ever-changing light effects.
