On Sunday May 13th 1917 the children were pasturing their flock as usual at the Cova da Iria, which was about a mile from their homes. They were playing when suddenly a bright shaft of light pierced the air. They described it as a flash of lightning. It was not really lightning, but rather the reflection of a light that approached little by little.
In spring in 1916 Lucia Dos Santos age 9, and her cousins, Francisco and Jacinta Marto, ages 8 and 6 respectively, were at a meadow with their sheep in (hamlet of Fatima). It started raining, and they hid in a small cave to escape the rain.
In August the children were prevented by the civil authorities to go to the meeting of the 13th in which had gathered an immense crowd. The children for two days were confined and threatened with many torments to make them deny, but they did not surrender, they were ready to offer their lives not to betray the promises made to the Lady.
It Occured in summer, when the seers were playing near the well of Lucia's house. The Angel said to them: "What are you doing? Pray! Pray a great deal. The Hearts of Jesus and Mary have merciful designs on you. Offer prayers and sacrifices continually to the Most High."
