In "The Wave" the archaeological gaze of the viewer is set in motion: a mass grave from the Spanish Civil War (1936–39) opens and closes itself. In 2011 we placed a camera above the spot where nine victims were buried after their execution by Franco’s supporters in June 1939. On day one of the excavation, a digging crane gently loosened the top layer of soil, until the archaeologists came across a skull with a bullet hole. Then the archaeologists continued their work by hand. The skeletons appeared, then disappeared, as if a strong wind blew that removed the sand and uncovered death, a primal truth.
