Lúcia dos Santos

Lúcia de Jesus Rosa dos Santos (March 28, 1907 – February 13, 2005), known as Sister Lúcia, was a Portuguese Carmelite nun and the eldest of the three child witnesses to the Fátima apparitions of 1917.
- Between May and October 1917, ten-year-old Lúcia, along with her cousins Francisco and Jacinta Marto, reported six encounters with a luminous entity near the town of Fátima, Portugal.
- Born to landowning peasants on the outskirts of Fátima.

The encounters culminated in the Miracle of the Sun on October 13, 1917, witnessed by an estimated 70,000 people.
- A luminous disc-shaped object was seen performing extraordinary aerial maneuvers.
- While the Catholic Church interpreted the events as Marian apparitions, some UAP researchers — notably Jacques Vallée and Portuguese researchers Joaquim Fernandes and Fina d'Armada — have analyzed the witness descriptions and concluded they more closely match UAP encounter patterns than traditional religious visions.

Lúcia entered religious life in 1925 and provided key documentation of the events.
- Wrote detailed memoirs of the Fátima events, including the famous Three Secrets of Fátima.
- Her testimony remains the primary source for the Fátima encounters.
- Beatified by Pope Francis in 2023.

Sister Lúcia's accounts continue to be studied extensively.
- Studied by both religious scholars and UAP researchers.
