Milankovitch Cycle in Myth

[Robert Tulip]

Looking at the question of the Great Year as a natural cycle, I have extracted this diagram of insolation over 50,000 years from public information on the rate of solar insolation on the summer solstice at 65 degrees north latitude. We see here that the precession of the equinox combines with the ellipticity and obliquity of the earth to generate a curve of light that closely tracks the Great Year, with high points 11000 years ago and 8000 years in the future and low points 23000 years ago and now. We see here a natural analog for the day of Brahma. The Great Year causes a cycle of the amount of light reaching the earth.

While the match between this natural pattern, known as the Milankovitch Cycle, and the Great Year is out by about ten percent due to the contribution of obliquity and ellipticity, it provides a natural empirical match and explanation for the equation between the Yuga and the Great Year, ideas at the basis of Indo-European mythology.

Seeing this as a model for the Golden and Iron Ages of Vedic myth, we see northern summer days got more light over ten thousand years until nine thousand years ago. The Zep Tepi Golden Age theory is that the Age of Leo was while northern summer days were getting more light each year, for 2150 years from 12500 before present, at the time of highest northern summer insolation. The silver age, around Gemini, began after northern summer days had begun to get less light. The Bronze Age, Aries, and the Iron Age, Pisces, were during periods when insolation in the northern summer was declining. Northern summer insolation will begin to increase again at the Age of Aquarius, heading for the next peak in ten thousand years time.

When we add the resonance between the earth and the solar system barycenter to this diagram, we can see and hear the singing of the earth to the tune of the Great Year, the song of the earth.

Hi Tat. The Milankovitch material is pure science, and provides an enframing story for Bauval's argument about Egypt. Here is some more material about how the cycle of the earth produces the cycle of light that is found in eastern and western theories of time.

Great Year appears clearly in this map, from jrscience.wcp.muohio.edu/studentresearc ... /data.html.

The peak of northern summer light is at 9000 BC, 11000 years before the present. The actual change of light is a product of the Great Year cycle of precession of the equinox.



Joining the two data sources gives this diagram. Mapping the insolation chart against data from http://jrscience.wcp.muohio.edu/stud.../web/data.html gives this result showing the variance of light at the northern summer solstice. The point with most light, 11,000 years ago, is at the top of the chart while the last ice age, 20,000 years ago, was in a period of low summer insolation.

http://www.ncdc.noaa.gov/paleo/pubs/...bers2006b.html says the intensity of summer insolation is primarily controlled by 20,000-year cycles in the precession of the equinoxes.

And here we see a Holocene Temperature Chart,* the interglacial period since the last ice age ended 12,000 years ago.

The trend line for the last eight thousand years matches the downward direction of insolation. However, from this chart it appears temperature was rising for four thousand years before that while insolation was falling.

Does the data from 12-8 thousand years ago just show that temperature change lagged light change, or could it actually have been warmer than shown in this chart when the ice age ended?

Can anyone explain the discrepancy between temperature change and insolation change for the period 12-8 thousand years before present?

The ice age continued while summer days got lighter, until 12,000 years ago. Does this show that the ice age was deepest when the summer days were darkest, and then continued until nearly the lightest point at 12,000 years ago which marked a phase change to the holocene interglacial?

Here is a clear depiction of how astronomy and climate fit together at the scientific level. The Milankovitch cycles of precession, obliquity and eccentricity of earth's orbit are combined in the yellow line showing solar forcing at 65 degrees north latitude in summer. The solar forcing line tracks glaciation, as you would expect, with the amount of light from the sun in summer the main factor in determining temperature.

Linking this planetary cycle to mythology, we see in India and Egypt and Mesopotamia that the rapid change in temperature at the end of the last ice age is remembered as a golden age.

And further back, over one million years we see here the close tracking of glaciation against insolation (not sure if that sounds more like ensoulment or insolence or insouciance).

And now it seems that an investigation into life during these cycles is in order. Obviously the climate changes were effecting life on the planet in certain ways, and so technically precession - due to the climate and solar light changes - has had an effect on life in a general sense. But the question is how much so. It would be nice to start up a book discussion with Robert Bauval on one of his books like "The Egypt Code" and get him to answer questions from members, sort of like what's going on with Robert Wright and "The Evolution of God".

Here is a discussion from another group

I am not looking for a "precise and completely unmovable starting point of the constellational zodiac."

The warmest moment in the most recent Great Year cycle was when the equinox was in Leo 11,000 years ago, but each point of maximum insolation is at a different point around the zodiac. The next warm maximum will be in 8000 years, ie in the Age of Scorpio. I am not suggesting that stars drive the great year, but that the great year is a function of orbital climate cycles of our planet. The cycle of light, the movement of the solstice from perihelion to aphelion and back, is about 21,000 years in duration. Precession of the perihelion shifts the solstice perihelion point against the precession of the equinox. There is no 'eternal return' of a fixed constellation marking a golden age, but a dynamic cyclic terrestrial system.

The need for a constellation zodiac arises from the natural twelve fold division of the year, providing markers for the tropical signs.

Robert,

I think you are saying that the Earth received a lot of sunlight and was warm 11,000 years ago, so when the equinox passes this precise point, it starts the Great Year, and this is a fixed place in what we in our culture call constellation Leo? So I take it you are trying to find some precise and completely unmovable starting point of the constellational zodiac and are placing this theory in competition with all the other theories?

From my understanding the galactic center, or perhaps we should mean the black hole at or near the galactic center, which moves through the signs in the Great Year, is late in the sign Sagittarius and will move across the solstice point some years from now. Should not this, the galaxy, have some significance in astrology?

Why is there any need for a constellational zodiac? The whole problem would go away and there would be no more complaining about it from the skeptics, and no more competing theories among astrologers, because the problem would cease to exist.

Thanks Ken

It is an interesting theme to look at the movement of the solstices as well as the equinoxes. We have the four points moving from one constellation to the next as follows

March equinox: Pisces-->Aquarius
June solstice: Gemini-->Taurus
September equinox: Virgo-->Leo
December solstice: Sagittarius-->Scorpio

The galactic center is fixed in the constellation Sagittarius. The sun previously passed this point during tropical Sagittarius, but since the solstice point moved across the galactic center in 1998, the sun now reaches it in tropical Capricorn. However, I don't see why this provides grounds to say we are entering an age of Capricorn.

I have just made a model to link the Great Year to scientific cycles of planetary climate - attached. We see that maximum light was at the Age of Leo, 11000 years ago, while maximum dark, over the current Great year cycle, is in the present Age of Pisces. This provides a scientific basis for linking the traditional ages with actual cycles of the earth.

Robert,

Have you considered the ultra unorthodox view that this isn't the age Pisces - Aquarius, but the age of Sagittarius - Capricorn? Astrology is alienated by science, and this view alienates the astrologers too!

The reason for this view is that the Great Year cycle relates to the galaxy. The galactic center is moving into Capricorn.

While this view is ultra alienating, it should not be because the Age of Aquarius is imaginary with no basis in any natural symmetry or coherent structures, while the Age of Capricorn does. This actually puts the Age of Capricorn on a better scientific and mathematical footing.

Over the past couple of years, astrologers and others had started to go in this direction with the Mayan "2012 end of time" scenario, but that belief seems to be dieing off now. It still has a grain of truth.

Just a thought,

Hi all

This whole topic raises interesting questions. I put the historical exclusion of astrology within the framework of the cultural evolution of the Great Year.

Dane Rudhyar, in his book Astrological Timing, argues that the zodiac age divides in 12 houses. Using the traditional theory that the Great Year is 25920 years in length, giving an Age period of 2160 years and degree period of 72 years, Rudhyar discusses the twelve houses of each Age as 180 years in length.

However, the actual spin wobble period of the earth is 25765 years, with some uncertainty as to precision, giving an Age period of 2147 years and a House period of 178.9 years. The astronomical period is slightly shorter than the traditional perfect sexagesimal number (2160 = 6x6x6x10).

I have proved that this 2147 year cycle of the spin wobble of the earth is in resonance with the entire solar system, through the pulse of the sun. Astronomically, the triple conjunction period of the three main perturbers of the centre of mass, Jupiter, Saturn and Neptune, is 178.9 years, equal to the house of the age. Uranus, the maverick, is the fourth biggest influence. However, what we see is that the Jupiter-Saturn cycle, as understood by Isaac Newton, establishes a cycle of the solar system barycenter with period 19.85 years, and nine of these cycles match to the Neptune return at 178.9 years. Within this temporal structure we also see fourteen Jupiter-Neptune conjunctions and five Saturn-Neptune conjunctions (35.8 years). The influence of Uranus is a slow ripple across the temporal wave of the solar system at the barycentre, making each house different in its wave structure. The triple conjunctions of JSN are separated by exactly one sign, so there are twelve JSN conjunctions over the period of an age, with the planets moving in and out of precise alignment in families like the Saros cycle of eclipses.

Assuming that the turning point of the Great Year was somehow accurately understood in our calendar, at the BC/AD moment, we entered the twelfth house of the Age of Pisces in May 1968. On this model of time, we entered the eleventh house of the age in July 1789 (fall of the Bastille) and the tenth house at the time of Galileo in September 1610. The first house began at the time of Christ.

How I read the implication of this structure of history is that the May 1968 house cusp of the age of Pisces was a time of ferment and change, but with the entry into the house over the last forty years traditional views have reasserted themselves in a dominant mainstream ideology. This ideology is modern and secular and rational and empirical, but has a bigoted disdain for human spirituality, including astrology. As a result, spiritual ideas have been driven underground, circulating via books and conferences and the internet rather than through mainstream media.

My view now is that the best way to return astrology into the mind of mainstream society is to focus on the relation between astrology and religion. My study of the Bible has convinced me that the Gnostics had a deep understanding of the Great Year, and that the identity of Jesus Christ as the alpha and omega is only explained by reference to the astronomical and astrological framework of the Great Year, where Christ marks the shift from the Age of Aries to the Age of Pisces.

My current study of the Milankovitch orbital climate cycles is a fairly decisive proof that the mythology of fall and redemption in the Bible is compatible with a true story about the evolution of the earth, seen in climate cycles of glaciation. At essence, the Vedic vision of the Yuga, explained by Yukteswar as a 24,000 year cycle, maps precisely in its rise and fall to the Great Year of the Ancients, the precession of the equinox, and to the natural cycle of warming and cooling of the earth. We see therefore that Christianity is a corrupted and degraded remnant of a former high wisdom, but fragments of that old shared planetary wisdom from Egypt, Babylon and India are encoded in the text of the Bible.

This diagram shows the main orbital cycle of the seasons against a galactic inertial reference frame.

It shows the period of earth's main climate cycle of light and dark over 21,636 years, as the product of the related motions of the earth's axial wobble and the rotation of the ellipse of earth's orbit.

This period is identified in glacial records as the main inertial driver of climate change over thousands of years, together with obliquity of the axis and eccentricity of the orbit.

This cycle maps directly to the insolation chart over 100,000 years also attached above.

To understand how the Milankovitch orbital cycles link to the myth of the flood, we can understand the flood as the long period over which sea level rose by over 120 meters starting at 22,000 years ago around the last glacial maximum.

Sea level rose by more than 120 meters to near its present level over the period from 22,000 years ago to 7,000 years ago. It seems this change is largely due to the insolation cycle.

See Post-Glacial Sea Level Rise from en.wikipedia.org/wiki/File:Post-Glacial ... _Level.png

Holocene Sea Level shows the detail of sea level over the last 9.000 years. It shows that over the period from 8,000 to 7,000 years ago, sea level rose by more than ten meters. http://merkel.zoneo.net/Topo/Applet/ is a site about effect of a change in sea level on worldwide topography.

The longer term pattern is shown at repeating a process that has occurred five times over the last 400,000 years as shown at Glacial and interglacial cycles as represented by atmospheric CO2, measured from ice core samples going back 650,000 years. and Variations in temperature, CO2, and dust from the Vostok ice core over the last 400,000 years

I would be interested to see global maps of sea level change over the last 20,000 years.
