During the opening of the exhibition ‘Retina’ a disused bar was repurposed to host several site-specific installations. A small fountain is installed in the glass display cabinet of the bar. At the base of the fountain is a photograph of an old sculpture by East German artist Margret Middell. Middell’s sculpture, titled ‘Sportler’ (English: ‘athlete’), has stood in front of the planetarium since 1996 with neither attributing text or inscription nor any lighting at night. The fountain bears the title ‘der Sportler’ in reference to Middel's original work and intends to direct the visitors' gaze to the adjacent Ernst-Thälmann-Park where the sculpture is situated.
The installation was inspired by artistic research initiated by the x-embassy collective in October 2019. The research involved questioning passers-by about specific works of art in public space in Berlin-Pankow. Middell’s sculpture was one of the subjects of the questionnaires. The wider project examines the work of female artists who were active in East Berlin before and after the fall of the Berlin wall, including many artists who are still active today.
