"To summarize chapter one: man is more ancient than our minds would like to believe. The earth has experienced violent cataclysms, mainly due to axis shifts and falls of huge meteorites. In these geological upheavals great civilizations disappeared without a trace.
Bhagavata Purana, a sacred book of India, speaks of four ages which have passed, each destroyed by the fury of the elements. Our present cycle is the fifth.
Hesiod was an eighth century B.C., Greek poet, whose major epics ascribed to him are Works and Days, a valuable account of ancient rural life, and Theogony, a description of the gods and the beginning of the world. In his Theogony he writes about a similar belief.
There were four ages in the past.
Ancient Egyptians divided history into three principal eras.
Even in China the people of Yunnan have preserved the memory of such ages." - "The Home of the Gods" Andrew Thomas page 129.
"In India, the number of years assigned to an eon (A 'Great Cycle' Mahayuga of cosmic time) is 4,320,000; whereas in Icelandic Poetic Edda it is declared that in Othin's warrior hall, Valhall, there are 540 doors, through each of which, on the 'day of the war of the wolf,' 800 battle-ready warriors will pass to engage the antigods in combat. But 540 times 800 equals 432,000!"
In "Hamlet's Mill" by Giorgio de Santillana and Hertha von Dechend, Gambit Inc. 1969 it states on page 162, "Odin in Valhalla says the Grinmnismal (23): 'Five hundred gates and forty more - are in the mighty building of Valhalla - eight hundred 'Einherier' come out of each one gate - on the time they go out on defence against the Wolf."
It continues with, "That makes 432,000 in all, a number significance from old."
"This number must have very ancient meaning, for it is also the number of syllables in the Rigveda. But it goes back to the basic figure 10,800, the number of stanzas in the Rigveda (40 syllables to a stanza) which together with 108 occurs insistently in Indian tradition. 10,800 is also the number which has been given by Heraclitus for the duration of the Aion, according to Censorius (Dedienatali, 18), whereas Berossos made the Babylonian Great Year to last 432,000 years."
Moreover, a Chaldean priest, Berossos, writing in Greek ca. 289 B.C., reported that according to Mesopotamian belief 432,000 years elapsed between the crowning of the first earthly king and the coming of the deluge. [The early Sumerian king list names eight kings with a total of 241,200 years from the time when "the kingship was lowered from heaven" to the time when "the Flood swept" over the land once more "the kingship was lowered from heaven" (Thorkild Jacobsen, The Sumerian King List, 1939, pp. 71, 77).]
No one, I should think, would wish to argue that these figures could have arisen independently in India, Iceland, and Babylon.
To complete one cycle of the zodiac--or, as it is called, one 'Great' or 'Platonic Year'--requires 25,920 years; which sum, divided by 60, (One soss, the founding unit of the old Mesopotamia sexagenary scale, still used for the measurement of circles, whether of space or time), yields, once again the number 432. So that the mythological count of 432,000 years not only cannot have been the product of any psychological archetype or elementary idea, but must have been discovered only through centuries of controlled astronomical observation." - "The Mythic Image" Joseph Campbell page 72-74.
