Peter and Paul Window: Domine Quo Vadis
St. Peter sees a vision of Christ while trying to leave Rome unnoticed. Peter asks, "Lord, where are you going?" (Domine, Quo Vadis) and Christ replies he is going to be crucified again. This inspires Peter to turn around and face his own martyrdom. Detail of Peter and Paul Window in the ambulatory of Bourges Cathedral, dating from c.1215-25.
