Above is a clip from the 1952 movie, Miracle of Our Lady of Fatima. Below are two eyewitness accounts of the miracle of Oct 13, 1917
O Seculo, October, 1917 (a pro-government, anti-clerical, Lisbon paper):
From the road, where the vehicles were parked and where hundreds of people who had not dared to brave the mud were congregated, one could see the immense multitude turn toward the sun, which appeared free from clouds and in its zenith. It looked like a plaque of dull silver, and it was possible to look at it without the least discomfort. It might have been an eclipse which was taking place. But at that moment a great shout went up, and one could hear the spectators nearest at hand shouting: "A miracle! A miracle!
Before the astonished eyes of the crowd, whose aspect was biblical as they stood bareheaded, eagerly searching the sky, the sun trembled, made sudden incredible movements outside all cosmic laws---the sun "danced" according to the typical expression of the people.
Standing at the step of an omnibus was an old man. With his face turned to the sun, he recited the Credo in a loud voice. I asked who he was and was told Senhor Joao da Cunha Vasconcelos. I saw him afterwards going up to those around him who still had their hats on, and vehemently imploring them to uncover before such an extraordinary demonstration of the existence of God.
Identical scenes were repeated elsewhere, and in one place a woman cried out: "How terrible! There are even men who do not uncover before such a stupendous miracle!"
People then began to ask each other what they had seen. The great majority admitted to having seen the trembling and the dancing of the sun; others affirmed that they saw the face of the Blessed Virgin; others, again, swore that the sun whirled on itself like a giant Catherine wheel and that it lowered itself to the earth as if to burn it in its rays. Some said they saw it change colors successively.
Fr. Ignacio Lorenco (Alburitel, 11 miles away):
I was only nine years old at this time, and I went to the local village school. At about midday we were surprised by the shouts and cries of some men and women who were passing in the street in front of the school. The teacher, a good, pious woman, though nervous and impressionable, was the first to run into the road, with the children after her.
Outside, the people were shouting and weeping and pointing to the sun, ignoring the agitated questions of the schoolmistress. It was the great Miracle, which one could see quite distinctly from the top of the hill where my village was situated---the Miracle of the sun, accompanied by all its extraordinary phenomena.
I feel incapable of describing what I saw and felt. I looked fixedly at the sun, which seemed pale and did not hurt the eyes. Looking like a ball of snow revolving on itself, it suddenly seemed to come down in a zigzag, menacing the earth. Terrified, I ran and hid myself among the people, who were weeping and expecting the end of the world at any moment.
Near us was an unbeliever who had spent the morning mocking at the simpletons who had gone off to Fátima just to see an ordinary girl. He now seemed to be paralyzed, his eyes fixed on the sun. Afterwards he trembled from head to foot and lifting up his arms fell on his knees in the mud, crying out to our Lady.
Meanwhile the people continued to cry out and to weep, asking God to pardon their sins. We all ran to the two chapels in the village, which were soon filled to overflowing. During those long moments of the solar prodigy, objects around us turned all the colors of the rainbow. We saw ourselves blue, yellow, red, etc. All these strange phenomena increased the fears of the people. After about ten minutes the sun, now dull and pallid, returned to its place. When the people realized that the danger was over, there was an explosion of joy, and everyone joined in thanksgiving and praise to our Lady.
