Your post contains information of great interest and very well presented, @ladyrebecca.
When you started the series, one of the figures that came to me was precisely Gilgamesh (I assumed you would tackle it at some point). Although the subject is not the Poem by Gilgamesh, I would note that I read it many years ago in a translation by the great universal writer Jorge Luis Borges. In the prologue this one declares: "It would be said that everything is already in this Babylonian book. Its pages inspire the horror of what is very old and force us to feel the incalculable weight of Time".
On the deluge (which you treat very well in that kind of archaeological walk you offer us), I would add that its condition is so archetypal (collective unconscious) that we also find it in the myths of the Nahuatl and Mayan civilization (in Mesoamerica). For example, in the Nahua myths it is narrated that the first Sun or age (their vision of creation is cyclic, and it occurred in consecutive periods that they called suns; there were five), that "was called Sun of Water. / In him it happened / that everything was taken away by the water / People became fish".
Thanks again for your post and for such an attractive series, @ladyrebecca. Greetings.
