Two days after his election to the papacy, Robert Prevost — not yet fully Pope Leo XIV in the world's eyes — made his way to a medieval sanctuary south of Rome where Augustinian friars have kept watch for six centuries. Now, sixteen months later, he has returned to fix his own likeness in fresco upon its walls, joining a lineage of papal portraits stretching back to 1630. The gesture speaks to something older than ceremony: the human need to mark the places that held us before history claimed us.
