One last info dump on Quetzalcoatl, from William H. Prescott's "History of the Conquest of Mexico":
>A far more interesting personage was Quetzalcoatl, god of the air, a divinity who, during his residence on earth, instructed the natives in the use of metals, in agriculture, and in the arts of government. He was one of those benefactors of their species, doubtless, who have been deified by the gratitude of posterity. Under him, the earth teemed with fruits and flowers, without the pains of culture [...] In short, these were the halcycon days....
>From some cause, not explained, Quetzalcoatl incurred the wrath of one of the principal gods, and was compelled to abandon the country. On his way he stopped at the city of Cholula, where a temple was dedicated to his worship [...] When he reached the shores of the Mexican Gulf, he took leave of his followers, promising that he and his descendants would revisit them hereafter, and then, entering his wizard skiff, made of serpent's skins, embarked on the great ocean for the fabled land of Tlapallan. He was said to be tall in stature, with a White skin, long, dark hair, and a flowing beard. The Mexicans looked confidently to the return of the benevolent deity; and this remarkable tradition, deeply cherished in their hearts, prepared the way, as we shall see hereafter, for the future success of the Spaniards.
Interesting stuff. I'm not sure what a "wizard skiff" is though. Some sort of magical boat, I guess. And Tlapallan is clearly Europe. My real question though is - what was Quetzalcoatl's end-game? We have many stories about benevolent White gods going around and spreading their knowledge, but did they not think that doing this would threaten the existence of their own Volk? Were things really just that different back then?
