Some Marian apparitions have only one purported seer, such as that of Our Lady of Lourdes. Other apparitions have multiple seers; in the case of Our Lady of Fatima, there were only three seers of the apparition itself, but miraculous phenomena was reported by a crowd of approximately 70,000 people, and even by others located miles away. In other cases, the entirety of a large group of people claims to see Mary, as in the case of Our Lady of La Vang. Some modern mass apparitions, witnessed by hundreds of thousands, have also been photographed, such as Our Lady of Zeitoun.
