Hello, @ladyrebecca. Your post is of great interest. It's a little uncomfortable for me to comment on him, as one of the areas of my academic dedication has been that of Mesoamerican civilizations. It is not in my interest to discuss it. I would simply like to briefly indicate that it is known that the Aztecs are the last autochthonous people that inhabited Ancient Mexico, it has even been indicated that they would be a kind of usurpers; in truth, the original civilization is the Nahuatl, which had several moments (Olmecs, Teotihuacans, Toltecs). This has been well-founded in the work of anthropologist Christian Duverger, Mesoamerica. Which, of course, does not deny the mythical or chronic stories to which you allude.
Miguel León-Portilla, one of the most renowned researchers-translators of Nahuatl literature, in one of his texts which he identifies with the title "Los soles que han existido", reads that in the second Sol (Sol de Tigre):
Said the old ones
that giants like that greeted each other:
"Don't you fall", because whoever fell,
fell forever.
Thank you for your post and greetings.
I find it tragic, the brutal fall of Mesoamerican civilizations and espexially the mindless destruction of precious artifacts, as well as myths and legends the Christians wanted forgotten - they would have been invaluable today.
