I found excerpts from Richard L. Thompson’s book Alien Identities: Ancient Insights into Modern UFO Phenomena on the Watcher site. Interesting data on the 13th of the month, orbs, roses, and much more. In discussing the apparitions at Fatima, Thompson writes:
These phenomena included the appearance of a glowing, globe- shaped vehicle and the occurrence of a shower of rose petals that vanished upon touching the ground. Showers of flower petals are often mentioned in Vedic accounts of celestial visitations.[In other words, the rebel angels who pretended to be Vedic gods did the same things as the rebel angels who are now pretending to be Mary... perhaps they are the same rebellious entities? - ww] For example, here is an excerpt from the description of Krsna's rasa dance in the Bhagavata Purana:
The demigods and their wives were overwhelmed with eagerness to witness the rasa dance, and they soon crowded the sky with their hundreds of celestial airplanes. Kettledrums then resounded in the sky while flowers rained down and the chief Gandharvas and their wives sang Lord Krsna's spotless glories.
As for the aerial globe, one eyewitness, Mgr. J. Quaresma, described its appearance on September 13, 1917, as follows:
"To my surprise, I see clearly and distinctly a globe of light advancing from east to west, gliding slowly and majestically through the air...Suddenly the globe with its extraordinary light vanished, but near us a little girl of about ten con- tinues to cry joyfully: 'I still see it! I still see it! Now it is going down!'"
As many paranormal and UFO researchers have noted, “Mary” doesn't say she’s Mary; she appears as a being, an entity, interpreted as Mary. The children at Fatima saw an “angel” before Mary’s appearance:
Before their meetings with the lady, the three children also had encounters with an angel. At the time of the first encounter they were tending their sheep at a rocky knoll not far from their home. They saw across the valley a dazzling globe of light like a miniature sun, gliding slowly towards them. As it approached, the ball of light gradually resolved itself into a brilliantly shining young man, who seemed to be about fourteen years old
Thompson agrees that, like Vallee and others, Marian apparitions share a connection with UFO events. But Thompson takes a broader perspective; well worth reading. The following comment by Thompson is essential to approaching the UFO phenomena; one that researchers who think we should discard various elements because they’re embarrassing or kooky or just plain weird just heed:
Thus the UFO continuum might be seen as part of a larger mystical-humanoid continuum. Fatima would probably appear as a typical point in this larger assemblage.
I haven’t read the book, but plan to. The page I’m linking to, and where I got this material from, is from the Watcher site, which is a religious site dealing with UFOs.
