Nidaros Cathedral in the Norwegian city of Trondheim is the northernmost medieval cathedral in the world, and it has an enduring history of destruction and restoration. This centuries-long perseverance is reexamined by the filmmaker Ismael Sanz-Pena in his short animation Persistence of Vision III. By playfully reorganising parts of a single image of the cathedral’s façade, Sanz-Pena transforms the building’s solemn religious imagery into a flipbook-style sequence that has saints, bishops and other holy people dancing.
