Grazia Varisco loves to puzzle our minds and senses. “Art is a question mark,” she explains. “It’s a game.” The Milanese abstract artist, born in 1937, distorts geometric shapes to confound the viewer’s sense of where the piece actually ends. Her art is simple and delicate yet sharp. Palazzo Reale showcases over 150 of Varisco’s works—explorations of chaos, balance, and form. —Thalia Bonas
