Each year, the Tate Britain, in London’s Westminster neighborhood, commissions a British artist to create a site-specific installation in its 1937 Duveen Galleries—a 300-foot-long Neoclassical hall designed by American architect John Russell Pope and English architects Gilbert H. Jenkins and W.H. Romaine-Walker. The latest piece, by conceptual artist and sculptor Cerith Wyn Evans, is composed of over a mile of white neon tubing—Wyn Evans’s signature medium— arranged in straight, curved, and spiraling forms, and suspended from the ceiling at over 1,500 points. Titled Forms in Space . . . by Light (in Time), the work echoes the repetitions and variations of musical notations as it unfolds across three sections of the hall. “It encourages visitors to orient themselves within an environment full of potential meanings and connections,” says assistant curator Elsa Coustou. “It could even be viewed as a celestial map.” The exhibition, which opened in March, will be on display until August 20.
