PORTLAND, Maine -- In the German artist Käthe Kollwitz's 1903 print "Outbreak," the revolutionary leader Black Anna waves a motley mob of peasants with pitchforks on to battle in a 14th-century uprising against wealthy landowners. "Käthe once told me that she had portrayed herself in this woman," Otto Nagel wrote in his biography of Kollwitz. "She wanted the signal to attack to come from her."
Kollwitz, one of the great German political artists of the first half of the 20th century, said her father "introduced me to socialism, socialism understood as the much-desired Brotherhood of Man." As a child she imagined herself righteously storming the barricades, leading the revolution. In the Portland Museum of Art's exhibit "Käthe Kollwitz Prints: Defending the Downtrodden," a modest survey of 23 prints, you see her radical devotion to this ideal as well as her despair at the tragedies that befell her and her country during her life (1867-1945).
