The History of Nero

After Nero's suicide there was a great deal of speculation, especially in the east, that Nero had not really died and was poised to make a dramatic comeback at any time. Fearful of Roman reprisals for speaking against the Caesars, but still wishing to warn their brethren about the threat that Nero posed, the early Christians used numerology to code in a reference for those with the wisdom to see. St. Peter's Basilica is allegedly built upon the spot where he was buried.
