In 1971 Holt created her first Locators, simple constructions made from two industrial pipes resembling a telescope or a camera viewfinder. They developed from Holt’s interest in photography—a serial, circular, and visual medium that enabled, as she often said, “vision to be fixed.” Holt first installed the Locators in her New York studio. Some faced outward, focusing on overlooked details such as an exhaust pipe or a cracked window. Others, such as this work, Locator with Mirror, and Locators with Loci, focused on the “how” of seeing rather than the “what.” When looking through the Locator of Locator with Mirror, the viewer must choose whether to look at their own eye or at themselves looking.
