Contributed by David Carrier / Spencer Finch’s new and recent work at Hill Art Foundation in Chelsea are set in dialogue with The Creation and the Expulsion from Paradise, a magnificent 1533 stained-glass window by Renaissance master Valentin Bousch. “Lux and Lumen,” the exhibition’s title, comes from Abbot Suger of the cathedral at Saint-Denis, who praised the power of stained glass to transform natural light, or lux, into sacred light, or lumen. Inspired by that medieval idea, and by his visit to Claude Monet’s pond and garden at Giverny, Finch’s Painting Air, an immersive hanging-glass installation, is a dramatic visual essay on light.
