The ceiling of the church is decorated in the center with a large canvas, certainly one of the largest in the province of Irpinia, depicting the episode of Simon Mago by the painter Scala from 1725. Next to it, four twentieth-century canvases portray the virtues.
Simon Mago is considered by Christian religions to be the first of the Samaritan heretics.
Further testimonies on his life do not have the official consent as they derive from apocryphal texts such as the Acts of Peter; according to these documents, Simon Mago resided in Rome during the reigns of the emperors Claudius and Nero. Here he gained fame and glory, but was challenged to a public confrontation by Peter and Paul of Tarsus. In this confrontation he died in two different ways, according to two different legends:
- He was buried so that he could rise again after three days, but he died in the tomb;
- During a levitation demonstration in the Roman Forum before the Emperor Nero, for the prayers of his opponents addressed to God, he fell, breaking his legs and then being stoned from the square, frightened by the event.
