The Cathedral at Monreale in Sicily has an interesting mosaic made in the Byzantine manner sometime between the 12th and 13th centuries.

The Latin inscription tells us what is on the left side:
HIC PETRUS ET PAULUS IN ROMA ANTE NERONEM DISPUTAVERUNT CUM SYMONE MAGO
“HERE PETER AND PAUL IN ROME BEFORE NERO DISPUTED WITH SIMON MAGUS.”
At left are Paul and Peter, and between them and Nero is Simon Magus.

All that is told of Simon Magus in the New Testament is found in the book of Acts, where Simon is said to have practiced sorcery and influenced many people in Samaria. Simon was converted to Christianity by the preaching of the apostle Philip. Then Peter and John came to Samaria, and began to give people the Holy Spirit by laying hands on them. When Simon Magus saw this, he offered the two apostles money if they would give him the ability to transmit the Holy Spirit by the laying on of hands. The Apostles told him scornfully that the gift could not be purchased with money, and advised Simon to repent of his request. Simon then says, “Pray to the Lord for me, that none of these things you have spoken come upon me” — apparently repenting.
That means, of course, that the Monreale mosaic depicts an event not told of in the New Testament. So where did it come from?
As depicted in the mosaic, the tale used appears to be that found in The Acts of Peter and Paul, a tale written in the 5th century — so not biblical at all in the customary sense. But people in early times were very heavily influenced by fictional religious works not included in the Bible.
According to the Acts of Peter and Paul, both apostles appeared before Nero, arguing with Simon Magus:
“And on the following day Simon the Magian, and Peter and Paul the apostles of Christ, having come in to Nero, Simon said: These are the disciples of the Nazarene, and it is not at all well that they should be of the people of the Jews. Nero said: What is a Nazarene? Simon said: There is a city of Judah which has always been opposed to us, called Nazareth, and to it the teacher of these men belonged. Nero said: God commands us to love every man; why, then, do you persecute them? Simon said: This is a race of men who have turned aside all Judea from believing in me. Nero said to Peter: Why are you thus unbelieving, according to your race? Then Peter said to Simon: You have been able to impose upon all, but upon me never; and those who have been deceived, God has through me recalled from their error. And since you have learned by experience that you can not get the better of me, I wonder with what face you boast yourself before the emperor, and suppose that through your magic art you shall overcome the disciples of Christ. Nero said: Who is Christ? Peter said: He is what this Simon the Magician affirms himself to be; but this is a most wicked man, and his works are of the devil. But if you wish to know, O good emperor, the things that have been done in Judæa about Christ, take the writings of Pontius Pilate sent to Claudius, and thus you will know all. And Nero ordered them to be brought, and to be read in their presence ….”
On the right side is another scene derived from the Acts of Peter and Paul. The Latin inscription describes what is shown:
HIC PRECEPTO PETRI & ORATIONE PAULI SYMON MAGUS CECIDIT IN TERRAM.
“HERE AT THE COMMAND OF PETER AND PRAYER OF PAUL, SIMON MAGUS FELL TO THE EARTH.”

It is the account of Simon Magus flying:
“Then Simon went up upon the tower in the face of all, and, crowned with laurels, he stretched forth his hands, and began to fly. And when Nero saw him flying, he said to Peter: This Simon is true; but you and Paul are deceivers. To whom Peter said: Immediately shall you know that we are true disciples of Christ; but that he is not Christ, but a magician, and a malefactor. Nero said: Do you still persist? Behold, you see him going up into heaven. Then Peter, looking steadfastly upon Paul, said: Paul, look up and see. And Paul, having looked up, full of tears, and seeing Simon flying, said: Peter, why are you idle? Finish what you have begun; for already our Lord Jesus Christ is calling us. And Nero hearing them, smiled a little, and said: These men see themselves worsted already, and are gone mad. Peter said: Now you shall know that we are not mad.
Paul said to Peter: Do at once what you do.And Peter, looking steadfastly against Simon, said: I adjure you, you angels of Satan, who are carrying him into the air, to deceive the hearts of the unbelievers, by the God that created all things, and by Jesus Christ, whom on the third day He raised from the dead, no longer from this hour to keep him up, but to let him go. And immediately, being let go, he fell into a place called Sacra Via, that is, Holy Way, and was divided into four parts, having perished by an evil fate.”
That is what we see in the mosaic. In the background is the tower framework from which Simon rose into the air, and we see him above, suddenly dropped by the (supposedly invisible) devilish angels, and falling to earth.
So there you have it. The Simon Magus who apparently repented in the book of Acts is turned into an unrepentant deceiver by the writer of this bit of early Christian “fan fiction.” It is interesting and often surprising to see the great extent to which Christian art was influenced by apocryphal and pseudepigraphical writings outside the New Testament.
