On 13 October 1917 the children surrounded by a crowd of 70.000 persons under a torrential rain, Lucy asked again of the Lady:"What do you want from me?" she answered: "I am the Lady of the Rosary, I desire here a chapel in my honor to be built, that people continue to recite the Rosary every day. Will the war finish. The war is going to end, and the soldiers will soon return to their homes." Then Lucy asked: "may I ask you for cures and conversions, will you grant them?". "Some yes, others no. It is necessary that they ask pardon for their sins, that they don't offend God our Lord,and that he is already too much offended." "Do you Want anything else from me?" Lucy asked. "I do not want anything more."
Then She opened her hands again and She launched a ray of light in the direction of the sun as Lucy shouted that they should look at the sun. At this point the promised sign happened, Lucy shouted to look at the sun, the rain stopped suddenly and there appeared an exceptionaly bright sun but not dazzling. The sun began to turn as if projecting in each direction bands of light of each color that lit and colored the clouds, the sky, the trees, and the crowd. It stayed for some moments then it went back to its normal position, it stayed still for a small while and then it happened again. Suddenly it looked as if it stood out from the sky to fall headlong on the crowd, that was looking terrorized, they fell to their knees and begged mercy. Meanwhile the children saw a Lady dressed like the white of the sun with a blue cope, St. Joseph with the Child Jesus that blessed the world.Then after this vision they saw The Lord bless the world, standing next to Our Lady of Sorrows. After these visions the Lady of Mt Carmel finished the miracle. The people then became aware that there clothes were completely dried.
One of the principal anti-clerical publications of the day was O Dia, a major Lisbon newspaper. On October 17th, O Dia reported the following: At one o'clock in the afternoon, midday by the sun, the rain stopped. The sky, pearly gray in color, illuminated the vast arid landscape with a strange light. The sun had a transparent gauzy veil so that eyes could easily be fixed upon it. The gray mother-of-pearl tone turned into a sheet of silver which broke up as the clouds were torn apart and the silver sun, enveloped in the same gauzy gray light, was seen to whirl and turn in the circle of broken clouds. A cry went up from every mouth and people fell on their knees on the muddy ground. The light turned a beautiful blue as if it had come through the stained-glass windows of a cathedral and spread itself over the people who knelt with outstretched hands. The blue faded slowly and then the light seemed to pass through yellow glass. Yellow stains fell against white handkerchiefs, against the dark skirts of women. They were reported on the trees, on the stones and on the serra. People wept and prayed with uncovered heads in the presence of the miracle they had awaited.
