The artist Christo, who died in 2020, made his mark on the world figuratively and literally. Born Christo Vladimirov Javacheff in 1935, in Bulgaria, he studied art in Sofia under the Communist Regime, but fled West to escape oppression. Known for his interventions in public spaces, Christo worked on a monumental scale, seeking the artistic freedom he didn’t have in his early life. He and Jeanne-Claude, his wife and artistic partner, wrapped in fabric such landmarks as Paris’s Pont Neuf and Berlin’s Reichstag, simultaneously concealing and revealing them. “They exist in their time, impossible to repeat,” Christo said of his projects. “That is their power, because they cannot be bought, they cannot be possessed.” This exhibition at Gagosian brings to life a 1968 project that was never realized, an installation that explores themes of air and ephemerality. Though small scale, the work foregrounds his grander projects, revealing how his creative practice came to be. —Maggie Turner
