Our Lady of Fatima is the title given to the Blessed Virgin Mary after she appeared to three shepherd children at Fátima, Portugal on the 13th day of six consecutive months in 1917, starting on 13 May. The three children were Lucia dos Santos and siblings Blessed Francisco and Blessed Jacinta Marto. The title of Our Lady of the Rosary is also sometimes used in reference to the same apparition because the children related that the Lady in the apparition specifically identified Herself as "the Lady of the Rosary."
Lúcia described seeing the lady as "brighter than the sun, shedding rays of light clearer and stronger than a crystal glass filled with the most sparkling water and pierced by the burning rays of the sun." According to Lúcia's account, the lady confided to the children three secrets, known as the Three Secrets of Fatima. She exhorted the children to do penance and to make sacrifices to save sinners. The children wore tight cords around their waists to cause pain, abstained from drinking water on hot days, and performed other works of penance. Most important, Lúcia said that the lady asked them to say the Rosary every day, reiterating many times that the Rosary was the key to personal and world peace.
