Celmins began experimenting with double-image prints following such double-image drawings as 'Untitled (Desert-Galaxy) 1974'. She combined images from photographs she had collected which were particularly significant to her. The 'Concentric Bearings' prints form an important series which were produced with the Gemini G. E. L. print workshop in Los Angeles. The series explores images of 'turning space'. The rotary device shown here is taken from Marcel Duchamp?s 'Rotary Glass Plates (Precision Optics) 1920'. Duchamp?s machine produced optical illusions by spinning an abstract design. Celmins drew Duchamp?s rotary device from a photograph and then transferred it to the plate using photogravure. It is placed next to Celmins's own image of stars turning in the night sky.
