The apparition known as Our Lady of Fatima came to three shepherd children
six times between May and October 1917. During these apparitions, Mary asked the
children to keep 3 secrets from the world, and to pray for peace and repentance.
She told them of a heavenly sign that would be seen by many, and on October 13, 1917
(her final apparition) the sun danced in the sky above over 70,000 witnesses. This
spectacular solar event - unexplainable by natural means - fulfilled her earlier
prediction proving the prior apparitions were authentic.
