She worked without reference to the fiery proto-Cubism of those years, the representational, classical past as dead as the Second Reich itself, dead, dead!—as dead as the Tsarist officers who’d now sunk beneath their own weedy mucky parade grounds so that the Party of Lenin and Stalin could march across their moldering faces. Since 1912 she had kept a room on Siegmund-shof for her plastic arts. That was where she would create the mourning woman out of stone. Mostly she carved, etched, and painted in that flat on Weissenbürgerstrasse. Those were the years when the figures in other people’s paintings began to go ever flatter, more garish, more distorted, the colors hurtful to her although she liked some of the galloping calligraphic riders in Kandinsky. Grosz’s desperately angry caricatures, the X-ray bitterness of Otto Dix, not to mention abstract constructivism; she didn’t swim with that tide. Käthe Kollwitz kept painting poor people, starving people (white figures in dark fields, dark chalk on brown Ingres paper), raped women, mothers with dying children, mothers with dead children. In the end she depicted mainly herself, her stricken, simian face thinking and grieving. She too was a mother with a dead child.
