Attila
Legends about Attila and his meeting with Pope Leo I

An anonymous chronicler of the medieval period represented the meeting of Pope Leo and Atilla as attended also by Saint Peter and Saint Paul, "a miraculous tale calculated to meet the taste of the time" This apotheosis was later portrayed artistically by the Renaissance artist Raphael and sculptor Algardi, whom eighteenth-century historian Edward Gibbon praised for establishing "one of the noblest legends of ecclesiastical tradition".

According to a version of this narrative related in the Chronicon Pictum, a mediaeval Hungarian chronicle, the Pope promised Attila that if he left Rome in peace, one of his successors would receive a holy crown (which has been understood as referring to the Holy Crown of Hungary).
