The relief frieze is one of the most sophisticated and formally most perfected arrangement of the Passion of Christ among the preserved sculptural ensembles from the 13th century throughout Europe. It shows the last supper, the payment of the pieces of silver, the capture, Peter's denial, two guards, the reading of Christ's sentence, the flagellation and the carrying of the cross. An important theme of the cycle is the juxtaposition of Judas and Peter; Judas, the sinner who was desperate and damned; Peter, the sinner who believed in forgiveness and became a saint.
