While a year is the length of time it takes the earth to circle the sun, a week is arbitrary, a concept constructed by mankind. In “Saturday, Tuesday,” the French artist Camille Henrot explores the societal associations and expectations attributed to each of these days. Saturday, a video, compiles footage from religious rituals at a Seventh Day Adventist Church, along with scenes of neurological testing, commercials, and political demonstrations. Henrot’s conception for Tuesday involves sculpture, watercolor drawings, and video, and grows out of the origin for the word Tuesday—Tyr—the Norse god of victory and war. —E.C.
