Mary Magdalene was a woman who, according to the four canonical gospels (Matthew, Mark, Luke, and John), travelled with Jesus as one of his followers and was a witness to his crucifixion and resurrection. In Gnostic writings, Mary Magdalene is depicted as Jesus's closest disciple who uniquely understood his teachings, causing tension with Peter, and is honored as the "apostle to the apostles". In Patristic writings, Mary Magdalene became conflated with other Marys and unnamed women mentioned in the gospels, and developed a reputation in Western Christianity as a repentant prostitute. Many alleged relics of Mary Magdalene, including her skull, a piece of forehead flesh, a tibia, and her left hand, are preserved in Catholic sites in France and Mount Athos, with notable displays and annual processions honouring them.
