The Fall of Simon Magus
12th century
Fresco
Left apse, Church of St. John, Müstair, Switzerland
The building on the right is the tower from which Simon took flight with the aid of his invisible demons. As in the Golden Legend and in other images of this episode, Paul kneels to pray while Peter commands the demons to let Simon fall to the earth. (The figure of Simon has crumbled away.)
