J. M. W. Turner captured the Romantic sublime in watercolors, oils, and prints, his manifestations of elemental power—sky, wind, water—reaching states of abstraction, modernity. “Light is therefore color,” he once said. He also said, enigmatically, “The sun is God.” This exhibition of Turners from the Tate features almost 90 paintings by the English artist, and was organized by the world-renowned Turner scholar David Blayney Brown. —Elena Clavarino
