Fiery Trigons: Great Mutation Cycle

Kepler’s chart collects another curious climate cycle coincidence.

The Great Confusion
Kepler’s esoteric astrology is mired in confusion, uncertainty and misinformation.

Renaissance scholars evidently struggled to:
1) interpret and recycle Muslim astrology
2) align astrology with the Christian Church and Christian Chronology.

The situation has only deteriorated in the Modern era.

Modern scholars struggle to:
a) interpret both Renaissance and Muslim astrology
b) reconcile astrology with their Religious and/or Gradualist beliefs.

For example:

A modern illustration of 40 Great Conjunctions actually shows 46 occurrences.

We can see that it takes 40 “great conjunctions” to return to our initial starting point (9 degrees times 40 = 360 degrees).

And there are plenty of other examples.

In relation to the fixed stars, it takes about 854 or 913 years for the event to return to a point near the start of the sequence. Some scholars have given it as 960 years.

Relative to the fixed stars, it usually takes about 913 years (46 conjunction intervals), or about 854 years (43 conjunction intervals).

The Great Conjunction Cycle
However, within the context of Johannes Kepler and the Fiery Trigon, most of the confusion can be avoided by establishing the current Great Conjunction rate of precession.


With the benefit of 20-20 hindsight it’s apparent [in nice round numbers] the Great Conjunctions of Jupiter-Saturn have advanced 45° [anticlockwise] in the last 300 years.

This implies the Great Conjunctions of Jupiter-Saturn take ~ 2,400 years to precess through 360° with the Fiery Trigon arriving in Aries every ~ 800 years / 120° / 40 conjunctions.

Very coincidently:

Some analysts have identified a ~ 2400 year cycle in several natural datasets.

The ~ 2400-yr Bray cycle
This cycle was identified by J. Roger Bray in 1968 from a consilience of geophysical, biological, and glaciological evidence contrasted with solar activity reconstructed from sunspot naked eye observations and aurora records.

The average length of this cycle has not been very clearly determined due to its irregularity and the difficulty from separating its signal from the ~ 1000-yr Eddy cycle.

It was originally described by J. R. Bray as a ~ 2500-yr cycle, and values as low as ~ 2200 years have been published.

My own estimate based on known occurrences of its lows during the entire Holocene is around 2450 years, quite similar to Bray’s estimate 50 years ago.

The Great Mutation Cycle
Modern commentators generally agree the Fiery Trigon returns “roughly” every 800 years.

57. Jupiter and Saturn are in conjunction roughly every twenty years.
If they meet first in Aries, they will next meet in Sagittarius, and then in Leo.
After that, the planets have conjunctions in other trigons – earthy, airy, and watery – before returning to Aries. This return to the fiery trigon is called a climacteric conjunction.
Taking precession into account, the whole cycle takes 786.4 years (i.e. roughly 800 years).

Researching possible explanations for a more accurate telling of the “Star of Bethlehem” has led to a rediscovery of the “method” used by Johannes Kepler to determine important dates in world history.

Kepler argued that great events in history occurred every 800 years using multiples of Jupiter/Saturn conjunctions.

The Magi by Garry Stasiuk

Successive Jupiter-Saturn conjunctions, slightly more than 240°apart, develop an interesting pattern as they step around the ecliptic, a rotating triangle with legs about 120°apart.

In relation to the fixed stars, it takes about 854 or 913 years for the event to return to a point near the start of the sequence. Some scholars have given it as 960 years.

Relative to a precessing co-ordinate system, it takes about 800 (794) years.

In astrology this “roughly” 800 year cycle is called the Great Mutation Cycle.

Jupiter conjoins Saturn in 19.859 years at an advance of about 123 degrees.

After three conjunctions, 59.577 years, it recurs at a mean advance of 8.93° – the first order recurrence cycle of Jupiter-Satum.

With this 9-degree advance every 60 years, in 40 conjunctions the advance moves around the circle and in 794.37 years returns to within 0.93° of the starting point – the second order recurrence cycle.

This 1° discrepancy would thus locate a third order recurrence cycle in 360 times 800 years, roughly speaking, a period too far in excess of recorded history to be useful as a frame of reference.

The first order recurrence cycle of Jupiter-Satum, 59.577 years – all values are mean values, based on mean motions – is probably the 60-year cycle of which the ancients spoke so much: the period of “social lag,” or the time between the introduction of a new invention or social innovation (Uranus), and its adoption and spread on the institutional level of organized society (Jupiter-Satum).

The second order recurrence cycle of these two planets is the Great Mutation cycle which meant so much in the Mundane Astrology, of the ancients.

Encyclopedia of Astrology – Nicholas deVore – 1947

Christian Chronology
Johannes Kepler faced a real dilemma at the beginning of the 17th century.

On the one hand:

The Christian Church believed two Great Mutation Cycles had occurred since the birth of Christ and that something marvellous must materialise early in the 17th century.

Astrologically, the end of 1603 marked the beginning of a fiery trigon, the start of the about 800-year cycle of great conjunctions;

On the other hand:

Johannes Kepler clearly indicated a new Great Mutation Cycle would begin in 1703 when the first Great Conjunction of Jupiter-Saturn fell in Aries i.e. the astrology of Kepler clearly contradicted some religious storylines and [more importantly] Christian chronology.

The Great Trigon of 1483/4 was supposed to herald “the arrival of the messiah”.

The last Watery Trigon was supposed to herald “apocalyptic changes”.

The Fiery Trigon of 1643 was supposed to herald “changes for the better”.


Arguably, it was this unacknowledged contradiction of Christian Chronology that propelled the clergy to inform the “educated classes” that astrology was no longer respectable.

By the end of 17th century astrology in England had declined from its once respected position as an accepted discipline among the intellectual elite and was largely forgotten by the educated classes.

The reasons for the decline are a complex blend of political, religious, economic, and scientific factors as well as a fundamental change in worldview brought about by the Scientific Revolution.

There is much disagreement among historians as to the extent and cause of this decline.

Contested Iconography: Was Isaac Newton an Astrologer, a Rational Mechanistic Scientist, or Neither? – James Frazier

Arguably, it was this unacknowledged contradiction of Christian Chronology that caused Christian beliefs to become enshrined in an Eclipse Canon.

Archaeoastronomy and the Eclipse Canons are more sophistry than science.


Either way:

It’s important to remember there are at least three types of Zodiac Year:

○ The 26,000 year precession of the March Equinox.
○ The 2,400 year precession of Jupiter-Saturn Great Conjunctions.
○ The 800 year Great Mutation Cycle of the Fiery Trigon in Aries.

Leona Libby’s Old Japanese Cedar Tree Chronology
Regardless of any beliefs in religion or astrology there are some very surprising similarities between Leona Libby’s Old Japanese Cedar Tree chronology and the 800 year Great Mutation Cycle of Jupiter-Saturn conjunctions during the 2nd millennium CE.

In fact:

Leona Libby’s Old Japanese Cedar Tree chronology provides several clues that help the independent observer understand why the Great Mutation Cycle acquired it’s name.

Furthermore, Leona Libby’s Old Japanese Cedar Tree chronology suggests the last Great Mutation Cycle lasted for 799 years.

More specifically:

○ The Great Mutation Cycle began at the Heinsohn Horizon minimum in 914.


○ The Hecker Horizon maximum occurred halfway through the cycle.


This is where Radiocarbon calibration really goes off the rails.


○ The Great Mutation Cycle ended in 1713 at the Maunder Minimum minimum.


Kepler’s Karma
The ultimate irony being:

Johannes Kepler’s esoteric astrology now appears far more respectable than the Christian Church of the 17th century [and it’s associated chronology].

    Extrapolating 400 years from 1713 we get 2213 AD when the earth fan might get dirty again while Jupiter and Saturn do their “conjunction”. This is 194 years in the future or roughly 17 sunspot cycles (194/11.6) ahead. Definitely an Isaiah prophetical moment.

  2. Yes, one step at a time. Thanks for introducing me to Solar system live, it is better than Home Planet to check conjunctions.
    A quick post here, which may need correcting. I checked out dates that have a sound origin from tree rings plus other sources, and that also seem to align to the Eddy cycle. Very near to conjunctions. All dire events from archaeology and geology.
    4375bce > 4375
    3550 (not accurate) > 3559
    3195 > 3202
    2345 > 2348

    So the Stars do seem to control our fate.

  3. A side-piece, in relation to this: “That, they argue, is what prehistoric, preliterate man was trying to tell us or preserve knowledge of, by using his scientific language, mythology.”, from The Magi by Garry Stasiuk, talking about Von Dechend and de Santillana.
    My initial foray into the prehistoric was not about science per se, but a curiosity regarding Females in eye-catching pairs.
    As evidence unfolded bit by bit, study in prehistory became study in agriculture, principally the cereals, their cultivation and how those lessons of its cultivation were entrenched and established as myth. Most of the old customs and lore of the old world are no more than remnants of that ancient myth.
    Ancient agriculture and the study of the heavens go hand in hand.

    It was originally described by J. R. Bray as a ~ 2500-yr cycle

    Bray was right, but with the added influence of Uranus the solar equivalent is ~2400 years as stated. It’s a 25:24 relationship.

    LH said: Extrapolating 400 years from 1713 we get 2213 AD

    Er…that’s 500 years.
