What goes up must come down / Soil archive (Light boxes)

Ongoing wall work covering all floors of the building in the form of a text and image collage, presented in ceiling-high light boxes on each floor. Eight soil samples are taken from the various layers of the excavation pit at the Postblock Areal Süd site, corresponding to the number of floors in the building, and analysed under a microscope using soil science methods. We focus on the solid components in the soil. The samples are photographed under the microscope and greatly enlarged so that, for example, a grain of sand from the excavation pit appears in the light box to be about the size of a fist-sized boulder. Due to the transfer of tiny particles into the macro range and transmitted light photography, which gives the image radiance and a distant effect, the photographs initially appear as abstract image compositions. Only when viewed up close, when reading the title, brief information about the background and particle identification, does the context become clear and provide information about the extent of human influence on the soil and ‘what else is there’ beyond anthropocentric penetration, following the image of the soil as a store of information and memories.
