What about the sign of “a night illuminated by an unknown light” before the outbreak of war? According to Fatima Prophecies, “on January 25, 1938, a remarkable display of aurora borealis was visible across Europe, the year before World War II began.” The Secrets of Fatima elaborates: “This aurora appeared as far south as Galicia, Spain, where Sister Lucy was then cloistered, and she, the only survivor of the three Fatima shepherds, recognized it immediately as the sign. Visible even to Pius XI in Rome, the unprecedented aurora was accompanied by a ‘crackling’ sound, possibly attributable to discharges of atmospheric energy. Indeed, in many areas of Europe, panic broke out, as the populace concluded that the world was on fire and that the End had come.” This display of northern lights might have illuminated the night in some spectacular fashion, but even in 1917 the aurora borealis was hardly an “unknown light.” Also, again, Lucia revealed this prophecy after the fact.
