The art of Ceija Stojka can look like it was painted in a rush, as if she had to catch the image before it disappeared from history. Stojka, who lived from 1933 to 2013, was Austrian-Romani (a minority often referred to as Gypsies), and the survivor of three Nazi death camps. She was a child during that horror, and her pastoral settings, invaded by German SS in black uniforms strapped with brown leather—swastikas and barbed wire spider-walking into the scene—have a shocked immediacy and color. Her vision is unblinking. More than 100 works are on view. —L.J.
