25,920 and the Synodic Month Average

In my various articles, you'll see me using or referring to what I call the " intercalary term " or " nominal term " of 25,920

25,920 is most often known by the name " Great Year ", and most commonly attributed to Plato ( Incorrect )

I've been able to show there's a relationship between this term 25,920 , and the use of figurate numbers like 666, 153 and 2701

To the best of my knowledge, this relationship has been lost to the world of mathematics for several thousand years ( I've not been able to find any work on it ), and hopefully this as well as my future threads will shed some light on this rather extraordinary method of mathematics

According to Wikipedia:


The term Great Year has two major meanings

It is defined by scientific astronomy as "The period of one complete cycle of the equinoxes around the ecliptic, or about 25,800 years". A more precise figure of 25,772 years is currently accepted. The position of the Earth's axis in the northern night sky currently almost aligns with the star Polaris, the North Star. This is a passing coincidence and has not been so in the past and will not be so again until a Great Year has passed

The Platonic Year, which is also called the Great Year, has a different more ancient and mystical meaning. Plato hypothesized that winding the orbital motions of the Sun, Moon and naked eye planets forward or back in time would arrive at a point where they are in the same positions as they are today. He called this time period the Great Year and suggested that such a unified return would take place about every 36,000 years. There is no evidence that such a re-alignment has ever or ever will take place

By extension, the term "Great Year" can be used for any concept of eternal return in the world's mythologies or philosophies

Historian Otto Neugebauer writes:

The difficulty with the term " great year " lies in its ambiguity. Almost any period can be found sometime or somewhere honored with this name "

This is a term I've been able to show was fundamental to intercalation ( Synchronization ) between Lunar, Solar and Precessionary ( Zodiac ) calendars, and more than likely dates back to early Sumerian calendars

Using this allows the accurate prediction of eclipses and new moons, what Mesopotamians called " floods " in priestly literature, and exactly what house of the zodiac they are occurring in




If we look at the modern Judaic time keeping unit of the " chelek " ( Portion ), we'll find it's taken from the earlier Babylonian unit known as the " grain "
( Pronounced " she " ) ( See my thread on the unit of the grain )

The length of the month according to the Talmud:

The name " Genesis " itself, essentially means the same thing

The length of the synodic month average is given in the Talmud, traditionally attributed to Hillel II , also known simply as Hillel, an amora of the fifth generation in the Land of Israel. He held the office of Nasi of the Sanhedrin between 320 and 385 CE

He was the son and successor of Judah III

He is traditionally regarded as the creator of the modern fixed Jewish calendar. This tradition first appears in a responsum of R. Hai Gaon (written in 992[3]) cited by R. Abraham bar Hiyya in his Sefer Ha'ibbur (written in 1123). The citation explicitly refers to the year that this event happened, 670 of the Seleucid era, which corresponds to 358/9 CE

However, a number of documents have been found that indicate the calendar was not fully fixed in Hillel's time; most famously a letter found in Cairo Geniza (from the year 835/6) indicates that the holidays were observed on different dates from those predicted by the current calendar. The calendar did not reach its exact modern form until at least the years 922-924. According to modern scholar Sacha Stern, Hai Gaon only attributed the establishment of a 19-year cycle, and not other details of the calendar, to Hillel

Using this term allows us to synchronize the luni-solar calendar to the Mazzaroth ( Zodiac )

Part of the confusion surrounding this term of 25,920, lays in the fact there are terrestrial days, months and years, ( On Earth ), and then there are the days, months and years of the Mazzaroth

It's common in Biblical debates for people to claim the year was originally 360 days long and somehow, God lengthened the days so that we now have a year of ~ 365.25 days

The reality, is that the Mesopotamian calendar from which the Hebrew system of keeping time is drawn from, used the 360 day year as part of the Mazzaroth calendar, not the Earth year

Mesopotamians and Egyptians historically always used the synodic month average, and this doesn't jive with the claim that a year on Earth " used to be " 360 days long, nor does the math work out

It does, however, work with the intercalation of the separate calendars

In this case, a " month " is not the 29.53 days of the synodic month average, it's the 2,160 years of one house of the Mazzaroth which is 30 degrees, and a " day " is not the Earth day of 86,400 seconds or 25,920 parts, it's 72 years, which is one degree of Earth precessing

This allowed accurate predictions of eclipses as they happened in each house of the Mazzaroth

So, the reality is that understanding the 360 day " year " doesn't require a fantastical suspension of the laws of physics, the " God did it " explanation, it simply calls for one to be familiar with Mesopotamian mathematical astronomy and the conventions of the calculations that synchronized the different calendars

These solar / lunar conjunctions ( Eclipses AKA " Floods " ) were predicted using what's called the " ZigZag function "

The ZigZag function is a good illustration of the power of Mesopotamian mathematical astronomy

This allowed the accurate prediction of the synodic month average, so instead of the average being calculated from repeated observations, it was predicted using pure math

This ZigZag function is essentially a crude type of Fourier analysis,.... except it was done thousands of years before Fourier was born

This sinusoidal motion was the thing upon which the Mesopotamians applied their unique phrasing where they refer to the sky / night sky as " the seas "

They were referring to the mathematical waveform of the sinusoidal motion of the moon

They didn't actually think the sky was water, just like they didn't actually think the entire earth was flat

This literary phrasing probably co-evolved with the use of waterclocks, which timed the apparent motion of the moon through the sky
