This post begins a Theme relating to the TrigonThe conjunction of Jupiter and Saturn every 19.8 years. Three trigons span the entire Zodiac in 60 years resembling the three steps the Indian god Vishnu took to span the whole universe. event occurring on 21st December 2020, when Jupiter and Saturn are conjunct at dusk in the sky. This touches upon what such synchronicities mean for other long term periods seen from Earth, such as the Moon’s nodal periodUsually referring to the backwards motion of the lunar orbit's nodes over 6800 days (18.618 years), leading to eclipse cycles like the Saros. of 6800 days and even the Precession of the Equinoxes over 25,800 ± 120 years.
Jupiter is the second largest body in the solar system next to the sun itself. In fact, Jupiter is not far short of being a sun itself and, being the closest giant planet to the Earth, our planet is strongly influenced by Jupiter’s gravity which, unlike the Sun’s continuous pull to maintain Earth’s orbit around it, Jupiter pulls upon the Earth and the Moon on an episodic basis when the Earth is passing between the Sun and Jupiter.
The Trigon Period of Jupiter and Saturn
Being a dark, planetary body, the episodic pull of Jupiter follows a different pattern to each of the inner, terrestrial planets; Mercury, Venus, Earth and Mars, since each has a different orbital period which, combined with Jupiter’s orbit, brings each under Jupiter’s influence or absence. The combined episodic pull of Jupiter and Saturn, is visually seen in their conjuction every 20 years, which occurs just over a third of the ZodiacThe 12 constellations through which the sun passes in the solar year of 365.2422 days onwards, thus giving a cosmic significance to the equilateral triangle as a sacred geometry.
Only Earth’s large moon stops the axial tilt of the Earth from varying significantly, then causing large changes in climate which would have restricted the development of the relatively stable habitats and biomes we enjoy.
361 days: Jupiter and the Zodiac
The combination of Jupiter’s orbital period (of 4332 days) and Earth’s (of 365.2422 days) generates an interesting set of numerical facts since Jupiter passes through each of the twelve signs of the Zodiac in 361 days. This number is 19 times 19 days so that 12 times 361 days equals 4332 days. But these numbers are a product of the solar yearFrom Earth: the time in which the sun moves once around the Zodiac, now known to be caused by the orbital period of the Earth around the Sun. of 365.2422 days, since the day length on Earth is 1 year divided by the 365.2422 days due to its rotation. If the day length were less or more then Jupiter’s complete orbit would still be as long but the numbers from Earth would not.
This is a major aspect of what the megalithic astronomy had to learn, that the relative time lengths of the many cosmic periods, counted in days, could be numerically interrelated when quantified. The situation of the earth orbit and its rotation would present Jupiter as a bright moving star which completed its journey through the stars in 12 times 361 days. Jupiter and the Zodiac of 12 constellations would inevitably become fused as seen in the story of Zeus, the Greek god name for Jupiter whose symbol is the twelve-fold circle. The pre-Classical Greeks were matriarchal, following the lunar month of twelve whole lunar months within the solar year and, the solar year only arose as the patriarchal northern tribes occupied Greece after the Bronze Age collapse. The name Zeus is therefore not matriarchal since the Greeks had no “Z”. Zeus arrived in ancient Greece with the tribes displaced from the North escaping the worsening climate at higher latitudes. And, whilst 12-foldness is associated with the Sun being in one of the 12 zodiacal constellations, Jupiter defines these through passing through each sign (on average) in 361 days.
399 days: Jupiter’s synodic period
Twelve-ness is a massively widespread tradition (see John MichellWriter, sacred geometer, metrologist and mystic: his books were highly influential in defining the form of the British earth mysteries movement. – Twelve-fold Tribes for instance) and the brightest celestial body next to the Sun is the Moon which expresses twelve whole lunar months a year (plus 7/19 of a lunar month). The common lunar year was therefore twelve months long, taking 354.367 days to complete, this countable between thirteen full moons. It is no accident that the 12-ness of the lunar year is connected with Jupiter’s 12-ness of its 361 day years, since the Jupiter synod has a strong grip on our moon: the synod is 9/8 lunar years long – a musical whole tone. And Saturn also has a similar grip, its synod of 378 days being 16/15 lunar years long.
When the Earth passes by Jupiter, the latter goes retrograde or backwards relative to the stars, meaning it appears to travel east night-by-night, rather than the norm for all planets (and the sun and moon) of slowly travelling west in our skies, as they orbit. During this retrograde period, the planet describes a loop in the sky relative to the stellar background, before returning to where it should be in the stars. Between the loops of Jupiter’s synodicThe recurring time cycle of a given celestial phenomenon seen from the Earth. period the 398.88 days could be counted in days. This can only mean that over millennia, the Moon became synchronised by the regular proximity of Jupiter to our moon.
Our months today have divided the solar year into twelve months of 30 or 31 days, to resemble Jupiter’s 12-fold zodiac and 12-month lunar year, the Roman emperors vying to lengthen a month and name it after themselves (examples being October after Octavius, September after Septimius and August after Augustus). And since a zodiacal sign is traversed after 361 days by its definer, it is inevitable that there are not 12 solar years in a Jupiter orbit but just less (11.86 years). However, the fact that 4332 days is not 12 times 365.2422 days accesses, through its deficit, more subtle possibilities hidden in a numerical world of differences.
Differences between periodicities, especially involving the moon that rotates the Earth, define those periods through the fact that they endlessly repeat so that differences accumulate over longer periods and when these differences are divided into the periods, a new set of numbers are generated. One could call orbital systems differential calculators and modern math would describe them as potentially discrete systems, which form due to gravitational recurrence. This idea that the planetary and lunar systems generate numbers is somewhat hidden by our modern description of such systems as subject to gravitational dynamics. The numbers allowed the ancient astronomers to discover a static numerical view of planetary astronomy through counting days. In contrast, modern astronomy calculates the location of celestial bodies from first principles; especially when trying to visit planetary bodies in spacecraft.
