Pope Francis on Saturday canonized two siblings from Fatima, Portugal, who reported seeing visions of the Virgin Mary in 1917.
Francisco and Jacinta Marto were shepherd children aged 9 and 7 who said Mary repeatedly appeared and prophesied to them while they were grazing their sheep. As recorded by an older cousin, Lucia, who is also on track to become a saint, the children saw a vision of hell, the violent death of a pope, and Mary's prediction of the end of World War I and start of World War II.
Both Marto children died two years after their visionary experience in the Spanish flu epidemic. They are now the youngest saints in the Catholic canon who were not martyred. Their shrine in Portugal draws more than 5 million visitors annually, and their ceremony in Fatima on Saturday was expected to attract a million worshippers.
