World renown mathematician and expert in ancient astronomy claimed that
Thales could not have predicted the 585BCE solar eclipse because of lack of expertise at the time by either the Greeks or Babylonians. But a recent solar eclipse series discovered proves Babylonians/Assyrians knew of a predictable eclipse series and likely passed this on to Thales allowing him to predict an eclipse in 478BCE which duplicates the pattern. This new discovery proves Neugebauer was wrong about what the Babylonians could do though he knew it was theoretically possible to predict the time and location of a solar eclipse if based upon ancient records of a possible eclipse pattern that allowed for this. He was not aware that such a pattern actually existed and thus discounted both Thales and the Babylonians who are now vindicated! --------------------- Here's the rare predictable eclipse series observed by the Babylonians and Assyrians establishing predictable solar eclipses: http://www.geocities.com/siaxares/comp532-478x2j.JPG Here's the matching pattern for the Thales predicted eclipse in 478BCE during the corrected two-year reign of Nabonidus (480-478BCE): http://www.geocities.com/Athens/Parthenon/4653/709.gif - QUOTE REGARDING ISSUE OF THALES: It is reported that Thales predicted an eclipse of the Sun in 585 BC. The cycle of about 19 years for eclipses of the Moon was well known at this time but the cycle for eclipses of the Sun was harder to spot since eclipses were visible at different places on Earth. Thales's prediction of the 585 BC eclipse was probably a guess based on the knowledge that an eclipse around that time was possible. The claims that Thales used the Babylonian saros, a cycle of length 18 years 10 days 8 hours, to predict the eclipse has been shown by Neugebauer to be highly unlikely since Neugebauer shows that the saros was an invention of Halley. Neugebauer wrote: .... there exists no cycle for solar eclipses visible at a given place: all modern cycles concern the earth as a whole. No Babylonian theory for predicting a solar eclipse existed at 600 BC, as one can see from the very unsatisfactory situation 400 years later, nor did the Babylonians ever develop any theory which took the influence of geographical latitude into account. After the eclipse on 28 May, 585 BC Herodotus wrote: .... day was all of a sudden changed into night. This event had been foretold by Thales, the Milesian, who forewarned the Ionians of it, fixing for it the very year in which it took place. The Medes and Lydians, when they observed the change, ceased fighting, and were alike anxious to have terms of peace agreed on. Some doubt that Thales predicted the eclipse by guessing writing: .... a more likely explanation seems to be simply that Thales happened to be the savant around at the time when this striking astronomical phenomenon occurred and the assumption was made that as a savant he must have been able to predict it. http://phoenicia.org/thales.html |

To Stephen
It is almost incredible that you would comment on this matter when the practical transfer of the pre-Copernican equable 24 hour day to its heliocentric adaption to axial rotation at 15 degrees per hour is beyond you. Do you wish me to explain again how the Equation of Time,which provides the core principles,straddles both the pre-Copernican principles behind the 24 hour day and its heliocentric adaption. The only astronomical story worth knowing this year is how those core principles are used by everyone on the planet even as they are denied by really ignorant people like you who have found themselves the inheritors of the fudging by 17th/18th century cataloguers. How does it feel to adhere to an exceptionally dumb and astronomical incompetent value for axial rotation* despite the fact that the transfer from the pre-Copernican principles to the heliocentric adaption for independent and constant axial rotation is easy to comprehend ?. That you manage to live with an incompetent astronomical value for a year (never mind 3 centuries) definitely highlights your indoctrination rather than your intelligence. * http://hypertextbook.com/facts/1999/JennyChen.shtml |

To Larry
People like Tonkin operate within very strict borders,mostly propping up the 'primitive' Greeks to justify their empirical inheritance, and those genuine investigators who have sought to extend the historical or technical borders have been ostracised such as Stecchini. http://www.metrum.org/measures/measurements.htm Having spent the day at Newgrange * which happens to be not only one of the oldest known Western structures but also an astronomical clock marking the annual cycle,the one fact I can come away with and which these guys should be ashamed.As contemporaries use a calendrical/celestial sphere format and those ancients used a different format to register the annual cycle,I live among those who could not build the Newgrange solstice marker because every 4th year has a different cycle that the previous 3 years due to the calendrical correction. I would not be ashamed to stand in the presence of those ancient astronomers while these punt imposters with their emoticons have little regard for the annual natural cycle reflecting axial and orbital motion. * http://www.iol.ie/~geniet/eng/newgrang.htm |

Thanks Stephen, my foot is often in my mouth which sometimes hampers
adequate communication to others which is apparent in this case. Thanks. It is true the exeligmos pattern was well known to the ancients. That is the discovery that eclipses recur every 18 years. Otto Neugebauer knew of this predictable pattern and discussed it in relation to the Thales prediction and determined that while most eclipses fall in the 18-year pattern that does not allow for LOCATION prediction. Everybody back then could predict another ecilpse would occur in 18 years but they didn't have the ability to predict the location. Often they appeared on the opposite side of the globe. Thus Neugebauer, applying the exeligmos theory to the 585 BCE clearly noted that that theory would not have been able to help Thales predict the LOCATION of any eclipse. The pattern I am referencing is an extension of the 18-year pattern where eclipses every 54 years (3 x 18) will occur in a graduating pattern that would allow a specific region or location to observe these eclipses as a 'pattern' in relation to LOCATION. That's the difference here. That's what's new. The exeligmos 18-year pattern is of no use generally for location of eclipses unless they appear in a pattern such as this one, where both time and location became predictable. Neugebauer was unaware of this pattern which allowed for prediction of both time and LOCATION. Meaning what? Meaning you missed the point. This is a pattern previously unknown to modern academic astronomy as far as the Babylonians and others being able to predict the location of an upcoming eclipse. That's what this discovery is about. A hybrid pattern based upon the exeligmos pattern that allowed for the prediction of location. What is left after discovering this pattern of "regional" eclipses is determining if they occurred in the region of Babylon, when, and whether that pattern again occurred during the timeframe range for Thales. The eclipse occurring in 478 BCE is a rare eclipse that fits this new pattern which would qualify for the Thales eclipse if the rule of Alyattes or Nabonidus were datable to that year. The 478 BCE date for year 2 of Nabonidus fits the timeline of Martin Anstey. So it turns out it was not my foot in my mouth after all, but my foot in your ear maybe. Sorry if I didn't explain the theory sufficiently for you to grasp this. Even so, a little research would have revealed that Neugebauer dismissed the exeligmos rule as being able to allow Thales to predict the location of an ecilpse, so this was already aware of and already dismissed. The focus of this post was what Neugebauer missed, so you missed the key point. My experience is that post readers who are speed readers who scan these posts thinking they can grasp the context end up with their own foot in their mouths sometimes because they miss the some of the fine critical details. So in that regard, please re-read the post carefully before commenting next time and presuming the poster doesn't know what they are talking about, which apparently is not the case this time, though often I do make mistakes, right? Thanks for your reference though! Ciao Misha "Stephen Tonkin" wrote in message ...

A little harsh, surely. As I read it, Larry Wilson merely got his
terminology wrong and failed to follow his own advice. Perhaps he didn't even know the term Exeligmos, as I could not find it in his original post, in which case he may have assumed on first hearing it that it meant the same as the Saros cycle.

Perhaps he didn't even know the term Exeligmos, Then one must question why he was using the term. It is clear, from his first post, that he knows that the 18yr cycle is the Saros. It is also clear, from my initial response, that "Exeligmos" refers to what Wilson falsely claimed was recently discovered, i.e. the 54yr cycle. We all make mistakes. Indeed we do, but we don't all twist the evidence in order to make a point (e.g. using Biblical pseudo-chronology to re-date Thales's eclipse by a century or so, or pretending that the 54yr cycle is "recently discovered" when it was written in cuneiform!). Neither do we all respond to the statement of verifiable fact with, as Wilson did in his latest post, sniping sarcasm. I get thoroughly fed up at the way astronomy is misused by those with other, usually pseudo-scientific or pseudo-historical, agendas, and I have to admit to having little, if any, tolerance for it. Of course, everyone is entitled to his own beliefs and opinions, but that does not equate to an entitlement to try to pass them off as fact.

Dear Stephen, I stand corrected, partially. Sarcasm always backfires on me.
It won't be the first time and thanks for your further explanation. I need to make some clarifications. 1. Neugebauer indeed compared the Saros (18-year cycle) to the 585BCE eclipse and determined it could not be used effectively for a determination for LOCATION of a solar eclipse. 2. I stand corrected for implying the exeligmos cycle, which is 54 years 1 month, was the same as the Saros. I was aware that the ancients understood the 54-year cycle. But that does not address these series of eclipses, which I must emphasize makes a difference. That's because the same principle applies. That varying circumstances in the elliptical rotation of the Earth and Moon make for different kinds of eclipse pattern criss-crossing the earth. It's interesting with modern astroprograms to see how "artistic" the eclipses are, repeated patterns, etc. Even so, eclispes occurring every 54 years 1 month still don't always occur in the same location. So yes, even though the Babylonians knew of this cycle, it would not have helped them to predict the LOCATION of a specific eclipse for every pattern. But the patterns or eclipses change with every eclipse cycle. This particular pattern was one of horizontally oriented eclipses that just happened to occur in stages from of 15 degrees starting from the South Pole and rising to the North Pole. So it is this specific pattern of eclipses in the exeligmos series that made the third observed eclipse predictable. That's the difference. Many eclipses in the exeligmos series occur in varying patterns but not all consistently in the same location. In this case they did. The SUBJECTIVE experience of any location experiencing a total eclipse would have permitted them to predict both TIME AND LOCATION of a third eclipse. You need only first recognize the unique nature of these eclipses and confirm that they occurred at at time when the astronomy program at Babylon and in Assyria were in effect for observation. This was thought possible by Neugebauer but not known to him thus this is NEW in that sense. NASA and others have currentl thought based upon Neugebauer that the ancient Greeks and Babylonians did not have sufficient technical information to accurately predict the location of a solar eclipse. That is no longer a true statement. They did. The second application here is, with this rare eclipse pattern, whether or not the Thales eclipse utilized this information? That is, is the eclipse that Thales is thought to have predicted a predictable eclipse based upon this rare exeligmos pattern? After all, he did become famous. For sure, the 585BCE eclipse does not fit this pattern, so if that is the eclipse Thales allegedly predicted going through Ionia, then we are back to square one as to how he was able to do it. But, the only reference for this eclipse is Herododus and he puts this eclipse in the context of two non-contemporary kings, Alyattes and Nabonidus. Why? That's another story. But for the chronolog of this period, there is more than one timeline and history. I don't want to introduce this long topic but it is important to note that that timeline and issues of revisionism are two different topics. Persons expert in astronomy may not be so expert in interpreting revisionistic historical reference. But since we are only dealing with Herodotus at this point, I hasten to mention that he claims the king of Babylon at the time was Nabonidus. So it has to be considered. Right now 585BCE is not the rule of Nabonidus. But as noted, there is more than one timeline for thsi period and more than one reference, including that of the Bible, Josephus and Ktesias in particular. One of those timelines dates the 1st of Cyrus in 455BCE when he became king in Babylon and his overthrow of Astyages in year 6 of Nabonidus 20 years earlier, which dates the 6th of Nabonidus in 475BCE and his first year in 480BCE. Nabonidus only ruled for 2 years before turning over the throne to his son, Belshazzar. So if we lift the reference from Herodotus regarding Nabonidus mediating this peace agreement after the eclipse there is only a two-year window. That's not alot. But for a historical match with Thales, the eclipse would have to occur during these first two years when Nabonidus was active on the throne. Secondly, besides the dating of the eclipse, a LOCATION is part of the reference. Thales warned "IONIA" about the eclipse. Meaning he expected the eclipse in that region. The 585BCE eclipse did not go through Ionia. So 585BCE is out for a Thales match-up of a predictable eclpse in Ionia. However, getting back to 480-478BCE, the two years of the reign of Nabonidus in hopes of a match, when we test that period for a solar eclipse coursing through Ionia (just to be thorough), lo and behold there it is! in early 478BCE! But that still doesn't make that eclipse predictable. It fits the historicity as far as being during the active two-year reign of Nabonidus and occurring over Ionia. But the big question is, whether it was "predictable eclipse." So far, the only pattern of eclipses that would seem predictable were the ones occurring over Babylon in 817, 763 and 709BCE. So was the 478BCE eclipse predictable by an eclipse 54 years and 1 month earlier? That is, the eclipse of 532BCE? As you see from the graphic, IT WAS! It was predictable by the same pattern of exeligmos eclipses of 817-763-709BCE! That is the information being presented here. That, indeed, the Babylonians on rare occasion had observed predictable eclipses and that the one in 478BCE was predictable and that by some dating criteria that does occur during the reign of Nabonidus. If one is thus able to get past the propanga of revised history and revise the dating for Nabonidus, then it would explain how Thales predicted the eclipse. I think that's an interesting prospect. But of course, the proof is no longer in astronomy at this point but in comparison of ancient records as to which chronology is the most reliable. I'm not here to promote any particular chronology but to note that there is more than one for this period and for the reign of Nabonidus. For instance, Ktesias claims Cyrus was the son-in-law of Astyages whereas Herodotus and Xenophon claim he was his grandson. The contradiction alone suggests revisionism. Josephus claims Nabonidus ruled for 18 years and that there were 70 years from the last deportation (year 23 of Nebuchadnezzar) to the 1st of Cyrus. This adds 26 years to the Neo-Babylonian Period. Finally, Herodotus himself is claiming the eclipse event actually occurred during the time when Nabonidus (not Nebuchadnezzar) was ruling but that self-contradicts this eclipse occurring during the time of Alyattes, which is a couple of generations earlier. The self-contradiction, though is also a clue to revisionism, that is, the history reflects both eclipse dates, the original and the substitute. The substitute event was during the time of Alyattes but the original during the original reign of Nabonidus. That's why you have both kings mentioned. Thus, for those who actually locate the true eclipse, a predictable eclipse occurring over Ionia during the reign of Nabonidus, you have a confirmation for 478BCE. For those not understanding this clearly, the substitute eclipse and timeline point to the 585BCE event. Since the chronology issue historically is not really the expertise of an astronomy group and the focus is on the eclipse and predictability is to provide information regarding what the Babylonians and Thales were capable of during their day and noting WHEN the predictable eclipses per this special exeligmos pattern occurred for further consideration. Thus I'm not debating here whether or not 478BCE is a better date for year 2 of Nabonidus, only that a rare predictable eclipse did occur that year and that some "alternative" timelines had already dated this year as year 2 of Nabonidus. Thus, at some point when the dating is seen more authorative for 478BCE for year 2 of Nabonidus, then the Thales eclipse event would have an easy explanation for making him famous since he would have been able to predict that eclipse. Finally, for those thinking that this won't work because the current dating for the Neo-Babylonian Period is so confirmed, think again! It is based upon an eclipse event that doesn't work in 585BCE. At some level, therefore, the match-up of a predictable eclipse in 478BCE for year 2 of Nabonidus is proof the current timeline is in error and should be revisited. You can't use a mismatched eclipse in 585BCE to dismiss a matched eclipse elsewhere. It doesn't work that way. It's the other way around. The fact that Thales works out perfectly in 478BCE suggests that 585BCE was the wrong dating in the first place. Larry "Stephen Tonkin" wrote in message ...
