"The painter should paint not only what he has in front of him, but also what he sees inside himself. If he sees nothing within, then he should stop painting what is in front of him."
... and witnessing the state of the art today we shall add: If he sees really nothing in front of him, then he should also stop painting what is inside him
Caspar David Friedrich was born on 5 September 1774, in Greifswald, on the Baltic coast of Germany.
Happy Birthday!
