While the girls were happily biting the fruit of their innocent petty thieving, a thunderclap and a lightning flash zigzagged across an otherwise perfectly clear sky. . . . It was 8:30 p.m. Frightened, the children began to be sorry for their mischief when suddenly an Angel appeared . . . Conchita was the first to see him, hardly a minute before the others all cried out at the same time: "Aye! The Angel!" Then falling into an ecstasy, they contemplated him in silence. The Angel appeared to the children, wearing a blue tunic, with dark eyes and hair, a mat complexion, and "wings that looked as if they were made of fire," according to Conchita. "A very beautiful person, surrounded by a very strong light that did not hurt the eyes," the visionary again pointed out. According to Jacinta, "the Angel appeared to be nine years old, but 'very strong.' He looked like a young boy, but before him we felt great respect."
We are almost certain now that the angel who appeared at Fatima was also St Michael. At Garabandal, we are sure of that, since on the following 2nd of July the girls learned his identity from Our Lady herself.
