The number twelve is special in this instance because it is a main common harmonic multiple of the long term temporal waves that surround the evolution of the earth. A year naturally divides in two and four when length of days is mapped as a sine wave. Taking the next equal division of the year into three, as I explained at the previous thread mentioned in the OP, produces a natural twelve-fold division by combination of the duple and triple factors.

Here is a further new idea about why 12 is cosmically special. In the current thread Jupiter influencing sunspots , JimP has posted data on the regular barycentric cycle of period 178.9 years. The astounding thing about this solar period is that it is precisely 1/12 of an age (2147 years) and 1/144th of a Great Year. The earth’s precession is exactly correlated to the rhythm of the solar system.

As JimP quotes from from: “A Possible Relationship Between Spectral Bands In Sunspot Number and the Space-Time Organization of Our Planetary System”; written by H. Schwentek and W. Elling. http://esoads.eso.org/abs/1984SoPh...93..403S “when our solar system is realized to be a complete whole, a great organism, in which the planets are something like organs, then an internal relationship between the center of the system, the sun, and the planets may be assumed, at least as a working hypothesis”

The material I have presented here correlating Rome and the USA supports this basic thesis of logic with hard empirical data – backed by the amazing mathematics of the correlation between precession and the barycentre. The twelve-fold rhythm is simply a deeply imbedded causal reality in terrestrial time.

Yes for defining influence, but no for most historical dates. I have chosen main events in main timelines for which dates are well known, so in this sense error bars are not needed. The postulated influence over 2147 years will have an orb, with some powerful events having fairly precise matches, such as the battles of Zama and Normandy, and others, such as the founding of Rome and of America, having a much looser correlation. As well, like the influence of Jupiter’s perihelion on sunspot dates, there are bound to be factors which will stretch or shrink the causal links between particular times.

This question, and some of the comments, illustrate that my initial explanation has not been clear enough. The point is to start from the scientific mathematics of the 2147 year cycle to understand how deeply it is imbedded in the history of the earth as a main temporal structure. I know this is obscure for mainstream astronomy, but the mathematics is really quite simple if anyone took an interest. Next, the question here is, what patterns on earth are likely to illustrate this correlation? My method uses the dominant Western civilizations as a case study because they are prima facie the most complex ecologies of their day on our planet, as well as the only comparable entities with clear temporal records across the ages.

To test this hypothesis, I then went to a standard Roman history to find the main dates on a timeline of ancient Rome, producing most of the dates listed in the OP. I also added a small number of other dates (eg Plato=Kant, Pythagoras=Kepler) as I believe these illustrate deep similarities in the cultural role played by these men in their respective epochs.

The hypothesis, as a matter of long term biological precessional causation, is that the history of Rome should have an analogous shape, with 2147 years separation, to the history of the USA. In both we see phases of discovery, consolidation, expansion, conflict and attack – a historic outline with main specific events separated by 2147 years, corroborating the claim. The many cultural parallels between America and Rome are augmented by an exact and predictable cosmic pattern. The skeletons of the two histories run in parallel, and this is explained by precession as an astronomical prediction. This core finding makes it reasonable to look at any other set of events between analogous powers separated by one age to find parallels.

As I noted, this correlation is between the leading powers of the West. Hence the fact that the Romans and the English got rid of their kings at the same cyclic moment, with error 12 years = 0.5% between 510BC and 1649AD, is illustrative.

My comment that the twin towers correlation was ‘turning tables?’ was intended to suggest it had some opposite causal relation – attacked rather than attacking. I do not want to make too much of that as you are right that there are better matches. A much stronger correlation at the same phase, as I mentioned, is between the conflicts Rome vs Carthage/Greece and USA vs Iraq.
