Sagrada Famila (Brazil) — August 28, 1963 (1915)
Two brothers, F. and R. Eustagio, II and 9, saw a luminous sphere at treetop level. Through an opening they observed “several rows of people inside” and a thin, 3 m tall being, who glided down to the ground along two vertical beams of light. He walked with a strange, swinging motion, then sat down. He wore a transparent helmet, had one eye in the middle of his forehead, wore high boots that left a triangular imprint, and carried a box emit- ting flashes. He made a threatening gesture and flew up to the sphere, which left. The children somehow became convinced that the being was “good” and would return. (Humanoids 37; Magonia)
