Leaving the esoteric level aside for the moment, The Sun behind the Sun is also a reference to a galactic alignment which takes place when the Galactic Centre lines up directly behind the Sun. The accounts of earlier suns, which we have previously discussed, occur at regular intervals and their advent is accompanied by catastrophes. Perhaps, the Sumerian King Lists also are a record of cosmic chaos. It may not be a precessional event because different planets/suns would align at different times.
After a deluge the world always "awakens to a new Earth." Quite possibly, also, to a new Sun. As previously discussed, records of these events, other than oral, are probably non existent - and all we have are the myths which most ignore.
The record of Enoch [sacred-texts.com] is most interesting in that, it tells of the human race as being just about ignorant of everything. It's the watchers who virtually "civilize" mankind. However, their progeny have genetic defects which lead to extremes of behaviour including cannbalism.
"They all reply'd, and said; "We will bind ourselves with an Oath to perform our Purpose, and invoke dreadful Imprecations upon our Heads, if we depart from our Enterprize before it be accomplished."
So they oblig’d themselves with an Oath; and implored an Arrest of Vengeance upon one another.
They were two Hundred, who in the Days of Jared came down upon the Top of Mount Hermon. The Mountain receiv’d that Name from the Oath by which they bound themselves, and the Imprecations they wilfully submitted themselves under."
What were they doing on Mt Hermon? How did they get there? What exactly was the oath?
We are also told that there were three different types of progeny - Giants, Nephilim and Eliudæans. The bible combines the first two into one, and doesn't even mention the third. However, the biblical account mentions that some Giants survived the deluge. Therefore, perhaps some Nephilim and Eliudaeans did as well.
The Comte De Gabalis suggests a method by which lost knowledge may possibly be gained.
