It was on May 13 1917, while they were tending a flock of sheep and goats, that three children aged ten, nine, and seven, saw a lady above an oak tree. The lady, they said, was clothed in light brighter than the sun, yet whose rays did not dazzle, but were rather soothing to the eyes and imparted a sort of serenity. It was difficult to describe because they had never experienced anything like it before. These three little sheepherders were named Lucia, Francisco, and Jacinta.
