The Deutsch-Russisches Museum Berlin-Karlshorst, the German-Russian Museum in Berlin, was initially only made open to members of the Soviet army. It was later opened to the public until the reunification of Germany on October 3, 1990. The reunification of the territories of the Deutsch Republic with the rest of Germany created new questions about the future of the museum, which remained closed until 1995, when it was reopened with a new project coordinated by a Russian-German scientific group. It is in this place, where rare historical documents are kept, which inspired Roberto Paci Dalò for Schwarzes Licht.

Schwarzes Licht, like Greuelmärchen, also reflects on the work of Heiner Müller Leben Gundlings Friedrich von Preussen Lessings Schlaf Traum Schrei: ein Greuelmärchen. The performance is presented at the conference Dichter und Künstler in Preussen a literary symposium organized by Wolfgang Storch and Hans-Christian von Herrmann, curators of the project Heiner Müller. Werkstatt.
