There are numerous saints to whom the ability to fly or levitate has been attributed. Most of these "flying saints" are mentioned as such in literature and sources associated with them.
The ability to levitate was attributed to figures in Early Christianity. The apocryphal Acts of Peter gives a legendary tale of Simon Magus' death. Simon is performing magic in the Roman Forum, and in order to prove himself to be a god, he flies up into the air. The apostle Peter prays to God to stop his flying, and he stops mid-air and falls, breaking his legs, whereupon the crowd, previously non-hostile, stones him to death.
The church of Santa Francesca Romana claims to have been built on the spot in question (thus accepting the claim that Simon Magus could indeed fly), claims that Saint Paul was also present, and that a dented slab of marble that it contains bears the imprints of the knees of Peter and Paul during their prayer.
Saint Francis of Assisi is recorded as having been "suspended above the earth, often to a height of three, and often to a height of four cubits" (around 1.3 to 1.8 m). St. Alphonsus Liguori, when preaching at Foggia, was lifted before the eyes of the whole congregation several feet from the ground. Liguori is also said to have had the power of bilocation.
Flying or levitation was also associated with witchcraft. When it came to female saints, there was a certain ambivalence expressed by theologians, canon lawyers, inquisitors, and hagiographers towards the powers that they were purported to have. By 1500, the image of the female saint in popular imagination had become similar to that of the witch. Both witches and female saints were suspected of flying through the air, whether in saintly levitation or bilocation, or in a Witches' Sabbath.
