In the evening of February 11, 1858, a young Roman Catholic girl,. Bernadette, went to fetch some firewood with her sister and another companion when a Lady who was indescribably beautiful appeared to her at the Massabielle grotto. Although the Lady did not tell Bernadette her name when asked at first, she told her to return to the grotto. On subsequent visits, the Lady revealed herself to be the "Immaculate Conception". This was a reference to the dogma of the Immaculate Conception which had been defined only four years earlier in 1854 by Pope Pius IX, stating that the Virgin Mary herself had been conceived without sin. Bernadette, having only a rudimentary knowledge of the Catholic faith, did not understand what this meant but she reported it to her parish priest, Father Peyremale. He, though initially very skeptical of Bernadette's claims, became convinced when he heard this because he knew the young girl had no knowledge of the doctrine. The Lady also told Bernadette to dig in the ground at a certain spot and to drink from the small spring of water that began to bubble up. Almost immediately cures were reported from drinking the water. And yet the water has been shown through repeated testing not to have any special curative properties. Today thousands of gallons of water gush from the source of the spring, and pilgrims are able to bathe in it. Countless purported miracle cures have been documented there, from the healing of nervous disorders and cancers to cases of paralysis and even of blindness. During the Apparitions, Bernadette Soubirous prayed the Rosary. Pope John Paul II wrote: "The Rosary of the Virgin Mary [is] a prayer of great significance, destined to bring forth a harvest of holiness".
