What do the Friedrich-paintings Das Große Gehege (The Great Enclosure) (1832), Hünengrab im Schnee (Dolmen in the Snow) (1807), Abtei im Eichwald (Abbey in the Oak Wood) (1818), Frau vor der untergehenden Sonne (Woman in Front oft the Setting Sun) (1818) and Nordische Landschaft/Frühling (Northern Landscape/Spring) (1825) have in common?

What declares itself to be nonsense declares itself to be harmless. Supposedly. Because the consequence of such self-determination is the famous jester's license, which a group of theater people in the GDR also claimed for themselves in the 1980s when they called themselves “Zinnober” and began making Punch and Judy shows for adults. Their play “Die Jäger des verlorenen Verstandes” (Raiders of the Lost Mind) can easily be read by the audience as a mockery of the GDR state system and its toleration is hard to believe in retrospect - but true.
