gardens, he arrived at the statue of Our Lady of Lourdes and began to see the miracle. He described himself in handwritten notes as "awestruck." He saw the same miracle on 31 October, again on 1 November (the date of the definition of the dogma) and then again on 8 November. He wrote that on other days at about the same time he tried to see if he could observe the Miracle of the Sun, but was unable to. He confided this information to a number of Vatican cardinals, to Sr. Pascalina Lehnert (the nun in charge of the papal apartments and his secretary) and finally to handwritten notes (discovered in 2008) that were later placed on display at the Vatican. In 2017, Pope Francis approved the recognition of a miracle involving two of the children involved in the Fátima event, Francisco and Jacinta Marto, which paved the way for their canonization. Believers' explanations Within Catholicism, the event is seen as the fulfillment of a promise by Mary, mother of Jesus, to the shepherd children who said she appeared to them several times before 13 October 1917. According to the children's accounts, Mary, referred to as the “Lady of Fátima”, promised them she would perform a miracle to show people they were telling the truth, and so caused the crowds to see the Sun make "incredible" movements in the sky. Catholics have regarded Mary as a powerful "miracle worker" for centuries, and this view has continued into the present. Various theologians and apologetic scientists have discussed the limits of scientific explanations for the event and proposed possible mechanisms through which divine intervention caused the solar phenomenon. Fr Andrew Pinsent, research director of the Ian Ramsey Centre for Science and Religion at Oxford University, states that "a scientific perspective does not rule out miracles, and the event at Fatima is, in the view of many, particularly credible." He states that a usual prejudice involves a lack of understanding of the scope of scientific laws, which merely describe how natural systems behave isolated from free agents. Concluding that the event is "a public miracle of the most extraordinary kind and credibility", he sees the year of the event, as connected to significant historical milestones that call for Fátima's message of repentance: Protestantism in 1517, Freemasonry in 1717 and atheistic communism in 1917. Theologian, physicist, and priest Stanley L. Jaki, concurs, concluding that
