Doubling Down: Nancy Holt’s Stone Enclosure: Rock Rings
Circles everywhere! Upon entering Nancy Holt’s 2018 solo exhibition at Dia Art Foundation in Chelsea, New York City the observer is engulfed by a network of flat circular line drawings, round cast shadows, and orbicular light pools. Circles also appear dimensionally: as dark voids cut into walls and as mirrored surfaces shaped into orbs. Very tangibly Holt’s circles telescope out, forming lens-less viewfinders. As one stoops to look through cast-iron spyholes, for example in Dual Locators (1972), a tunneling effect occurs: circles become layered onto circles.
