Huns
In Christian hagiography

After the fall of the Hunnic Empire, various legends arose concerning the Huns. Among these are a number of Christian hagiographic legends in which the Huns play a role. In an anonymous medieval biography of Pope Leo I, Attila's march into Italy in 452 is stopped because, when he meets Leo outside Rome, the apostles Peter and Paul appear to him holding swords over his head and threatening to kill him unless he follows the pope's command to turn back. In other versions, Attila takes the pope hostage and is forced by the saints to release him. In the legend of Saint Ursula, Ursula and her 11,000 holy virgins arrive at Cologne on their way back from a pilgrimage just as the Huns, under an unnamed prince, are besieging the city. Ursula and her virgins are killed by the Huns with arrows after they refuse the Huns' sexual advances. Afterwards, the souls of the slaughtered virgins form a heavenly army that drives away the Huns and saves Cologne. Other cities with legends regarding the Huns and a saint include Orléans, Troyes, Dieuze, Metz, Modena, and Reims. In legends surrounding Saint Servatius of Tongeren dating to at least the eighth century, Servatius is said to have converted Attila and the Huns to Christianity, before they later became apostates and returned to their paganism.
