In 1944, the mystic, author, and 33° Mason Manly P. Hall published a book
The article below (which alternatively interprets these beings as extraterrestrial) proposes a relationship between such entities and the South American revolutionary General Bolivar.
It must seem very strange to our readers to see me state that the Liberator had contact with aliens and received information from them. In saying this, I am basing myself upon the very important historical research of Don Luis Beltrán Reyes, which are rather well documented and therefore worthy of trust. At no point does he suggest that the three strange men that mysteriously interviewed the Liberator were aliens, but the characteristics of these beings, as described, are sufficient for me to sustain, as I do now, that they were in fact aliens without question. During the course of his famous military campaigns, Bolivar would meet with three mysterious men, very strange in their appearance, and whose arrival and departure, or no man knew the means through which this was achieved. According to the description given by Luis Beltrán Reyes, these three men were tall and distinguished in their manner. They wore white uniforms with white dress coats and golden cuffs, with the extraordinary detail that [the uniforms] were emblazoned with golden spikes that gave off a strange luminescence. They also wore Wellington-style boots, but the strangest feature was that their footsteps could not be heard as they walked. Moreover, some witnesses say that they were endowed with magical powers, such as the ability to become invisible whenever they deemed it necessary.
Aliens or immortals, one thing that cannot be denied is that they were snappy dressers.
