Well, to start out, we've discussed this passage from Joseph Campbell in the past which shows how precession is inter-related through different mythologies, including the Iclandic Eddas:
The Inner Reaches of Outer Space: Metaphor as Myth and as Religion
"For example, in the Hindu sacred epics...the number of years reckoned to the present cycle of time, the so-called Kali Yuga, is 432,000; the number reckoned to the "great cycle", within this Yuga falls is 4,320,000. But then reading one day in the Icelandic Eddas, I discovered that in Othin's warrior hall, there were 540 doors, through each of which, on the "Day of The Wolf" (that is to say at the end of the present cycle of time), there would pass 800 divine warriors to engage the antigods in a mutual battle of annihilation. 800 x 540 = 432,000.
...In Babylon, I then recalled, there had been a Chaldean priest, Berossos, who c. 280 BCE., had rendered into Greek an account of the history and mythology of Babylonia, wherein it was told that between the rise of the first city, Kish, and the coming of the Babylonian mythological flood (from which that of the bible is taken), there elapsed 432,000 years, during which antediluvian era, ten kings reigned. Very long lives! Longer even than Methuselah's (Genesis 5:27), which had been of 969.
So I turned to the Old Testament (Genesis 5) and counting the number of antediluvian patriarchs, Adam to Noah, discovered, of course, that they were ten. How many years? Adam was 130 years old when he begat Seth, who was 105 when he begat Enosh, and so on, to Noah, who was 600 years old when the flood came: to a grand total, from the first day of Adams creation to the first drop of rain of Noah's flood, of 1,656 years. Any relation to 432,000? ...it was shown that in 1,656 years there are 86,400 seven-day weeks. 86,400 divided by 2 equals 43,200.
And so it appears that in the book of Genesis there are two contrary theologies represented in relation to the deluge. One is the old tribal, popular tale of a willful, personal creator god, who saw that "the wickedness of man was great in the earth..." (Genesis 5:6-7). The other idea, which is in fundamental contrast, is that of the disguised number, 86,400, which is a deeply hidden reference to the Gentile, Sumero-Babylonian, mathmatical cosmology of ever-revolving cycles of impersonal time, with whole universes and their populations coming into being, flowering for a season of 43,200 (432,000 or 4,320,000) years, dissolving back into the cosmic mother-sea to rest for an equal amount of years before returning, and so again, and again, and again.
It is to be noticed, by the way, that 1+6+5+6=18, which is twice 9, while 4+3+2=9: 9 being associated with the goddess mother of the world and it's gods. In India the number of recited names in a litany of this goddess is 108. 1+0+8= 9, while 108 X 4 = 432. ...It is strange that in our history books the discovery of the precession of the equinoxes should be attributed to Hipparchus, second century BC., when the magic number 432 (which when multiplied by 60 produces 25,920) was already employed in the reckoning of major cycles of time before that century.]
It does seem worth while to check into how Norse mythology viewed the effects of precession on the circumpolar stars as well.
64. More fair than the sun, | a hall I see,
Roofed with gold, | on Gimle it stands;
There shall the righteous | rulers dwell,
And happiness ever | there shall they have.
66. From below the dragon | dark comes forth,
Nithhogg flying | from Nithafjoll;
The bodies of men on | his wings he bears,
The serpent bright: | but now must I sink.
This seems to point at something in the way of the descending Yuga cycle, which, when the Eddas are understood as mirroring the Vedic Yugas in the way that Campbell uncovered through the mathematical astrotheology, it makes sense to the see the Dragon associated with darkness and with sinking as relating the descending half of the Vedic Yuga. It sort of stands out. The poem is going from the Golden Age to the Descent. And this involves the Dragon of the circumpolar stars being dominant going into the descending Yuga cycle. Then eventually the Dragon gives way to the Bear as precession moves forward and the descent continues.
Ursa Major (Bear) was also called "Odin's Wagon" in ancient northern Europe. His son riding his wagon, and his feud with the world serpent is better known.
Yes, well that does seem to relate what's happening with the circumpolar stars as precession moves forward into the descending Yuga cycle. And as "Odin's warrior hall" gives a strong clue to precession by using the 432 method, "Odin's wagon" certainly comes off as doing the very same by showing a feud between Draco and Ursa Major according to the circumpolar stars moving through the Great Year. That was a nice addition to the topic.
