A most valuable reference given by Dodwell:

“Godefroid

 Wendelin… a list of ancient observations of the obliquity of the ecliptic, made by Thales, about 558 B.C.; Eratosthenes, about 230 B.C.; in his later years, Hipparchus, 135 B.C.; Ptolemy, 126 A.D.; and by several mediaeval astronomers up to the time of Tycho Brahe, 1587 A.D., and of Wendelin himself, 1616 A.D.; together with Wendelin’s theory of the cause of the change which had taken place during the ages up to his own time.”

An error and a premature conclusion of Dodwell:

“It was absolutely certain that every point on the mean observational curve in Figure 3 is precisely a point on a logarithmic sine curve.  The curve is therefore a certain and sure mathematical demonstration that in the year 2345 B.C., the earth’s axis was suddenly displaced by a major impact…”

 

A fundamental error in dating of Dodwell’s:

“the Great Solar Temple of Amen-Ra at Karnak, which was oriented to the setting sun at the summer solstice at the date of its foundation, about 2045 B.C. ”

 

A questionable flawed conclusion of Dodwell’s:

“these differences reach a unique maximum in the year 2345 B.C. ”

 

A missing list of Dodwell’s? – I don’t seem to find it… and the Data list provided under Figure 2 doesn’t provide the “additional…”:

“At the end of this chapter is a list of the determinations of the Obliquity of the Ecliptic, from which the curve has been derived”

 

A missing remark… Who’s the source of the dotted line in Figure 1? Dodwell?

“I have therefore used it here…” Well, seems my questions are answered by these words of Dodwell: “on a small scale, how the discrepancies appear when they are set out on a graph, and the Scale is magnified in Figure 2…”

 

What’s this “8¢”??? – A typo???:

“when the difference was as much as 8¢ greater than Newcomb's value…”

 

Is 525 BC a correct year or an error of Dodwell’s et al???:

“the conquest of Egypt by Cambyses in 525 B.C. …”  - Yes, as best I can tell, this event occurred in the spring or summer of 523 BCE. Cf. box K994 and C994 in my file ScriptureChronology.xls at this link.

 

Errors in latitude and year???:

“Crotona in Southern Italy, (latitude 39 degrees 7 minutes North),  about 515 B.C. …”  - Yes, likely, considering Pliny’s (in 1st century CE!) observation as quoted in Worlds in Collision, p. 320:

“For nearly the last thirty years, however, the observations derived from this dial have been found not to agree…”

 

Why only 26 ½ degree????:

“indicates a probable and actual value of about 26 1/2 degrees for that date…”

 

A possible case of circular reasoning by Dodwell???:

“It will be shown that in 2045 B.C., the foundation date of the Temple, the sun's solstitial declination, or maximum distance from the celestial equator, was 25 degrees, 9 minutes, 55 seconds.”

 

What’s the extent of Dodwell’s reliance upon flawed assumptions re latitudes and dates???:

“The full period covered by the curve is thus 4194 years…”

 

Typo – New line or margin format error:

“position on the

graph

.”

 

Ditto…II – Ditto re extent of reliance upon flawed assumptions…:

“it shows with certainty that a disturbance of the earth's axis occurred at the date 2345 B.C., corresponding to the 0º end of the curve…”

 

Ditto…III:

“enables us to obtain a numerical formula…”

 

Interesting, but can it be shown???:

“it seems probable… from an original inclination of about 5 degrees…”

 

Ditto…IV:

“The formula is…”


The fundamental Caesar Augustus’ death vs 14 CE error:

“about 14 A.D., at the end of the reign of the Emperor Augustus…”

 

The latest sudden change of the ecliptic around 10 CE!:

“about 14 A.D., at the end of the reign of the Emperor Augustus, the Roman mathematician Manilius noted a change in the obliquity of the ecliptic, which he attributed either, as he says, to "the discordant course of the sun itself, and some change in the sky, or through some change in the universal earth, by which it has moved away from its center, as I have detected myself, and I hear of also in other places." ”

 

Manuscript #2:

 

I don’t find Senusert in Velikovsky index, but, like Amenhotep II in the XII Dynasti, he too should probably be dated more accurately in the 7th or 8th century BCE:

“Senusert I of the XII Egyptian Dynasty at Heliopolis. This dates back to about  2050 B.C.”

 

1180 B.C.???:

“This form of gnomon, with a terminal ball, is found depicted on medals of the time of Philip of Macedon (359 B.C.); and this arrangement, which was common at Rome, is believed to have been introduced into Greece by Menelaus, King of Sparta, about 1180 B.C.”

 

Who is the true author of these words? Pliny or Manilius? The words are very similar, as similar as they would be expected to be out of a common Roman / Latin text! Cf. Velikovsky’s Worlds in Collision, p. 320!:

Manilius?:

“Manilius added these words, concerning his measurements: “This observation now for nearly 30 years is not consistent, either through the discordant course of the sun itself, and some change in the sky, or through some change in the universal earth, by which it has moved away from its centre, as I have detected myself, and I hear of also in other places.” ” (Dodwell, The Obliquity of the Ecliptic, Chapter 2)

Pliny?:

“…can be plainly seen from this passage of Pliny:… “For nearly the last thirty years, however, the observations derived from this dial have been found not to agree:whether it is that of the sun itself has changed its course in consequence of some derangement f the heavenly system; or whether that the whole earth has been in some degree displaced from the center, a thing that, I have heard say, has been remarked in other places as well; or whether tha some earthquake, confined to this city only, has wrenched the dial from its original position; or whether it is that in consequence of the inundations of the Tier that foundations of the mass have subsided.” “ (Velikovsky, Worlds in Collision, p. 320.)

 

What are the true dates for Ptolemy???

“Ptolemy, known as the “prince of astronomers,” who made astronomical observations at Alexandria from 127 A.D. to 151 A.D.,”

 

Doubtful date – 2000 BC:

“Dr. Breasted describes the Egyptian “Merkhet,” used for orienting temples from times earlier than 2000 B.C.,”

 

Typo:

“pair of compasses unsed”

 

Doubtful date:

“Vitruvius (B.C. 63 to A.D. 14)”

 

The 3 fingers pointing back… - i.e. false assumptions re ancient latitudes and dates:

“and only unless, the steadily increasing difference between these ancient observations and the normal curve of obliquity, as we trace it backwards into past ages, can be rightly ascribed to errors of the ancient observations.”

 

Where is the error of precision??? Is this a typo? Wikipedia has 1 Chinese foot = 13.12 Imp in.!

“13.32 English inches.  The gnomon itself was thus 8 feet 9 inches high, [13.32 x 8 = 8.88 ft = 8 ft 10.56 in / ToL©]”

 

Typo:

“within on[e] twenty-fifth of an inch”

 

Typo:

“one minute of arc [i]n the sun’s alititude”

 

Typo:

“the best wa[y] seems to be”

 

Typos:

I found multiple instances of erroneous double spacing (“  ”) in the files but I’m not marking those as they are easily found by common software tools…

 

Error in arithmetic? Isn’t 2’.1 + 2’.9 = 5’.0 ? Not 4’.9 ? Or is this a typo?

“The extreme range was thus 4’.9”

 

Treasurable reference worthy of pursuing:

“P. Gaubil, S.J. (1689-1759 A.D.), who was a French missionary in China. He extracted a considerable number of Chinese solstitial observations from numerous documentary sources.  He studied these very thoroughly, and communicated them to European astronomers in his Edifying Letters, published by Souciet in 1732.”

 

Treasurable reference worthy of pursuing:

“Laplace, recognizing the unique value of this work, rescued it from oblivion and published, in the French Connaissance des Temps for 1809, the portion dealing with the solstices and the meridian shadows of the gnomon observed in China”

 

Treasurable reference worthy of pursuing:

“The Emperor, on his part, was held to be “responsible to heaven, and if he neglected the calendar, he not only caused inconvenience to the people, but was considered guilty of an irreverence which diminished his virtue and endangered the dynasty.””

 

Treasurable reference worthy of pursuing – Is Chinese 1120 BCE really a 700 BCE date? Cf. Velikovsky!!!:

The most ancient part gives results of observations made as far back as 1120 B.C., but a section relating to the observation of a circumpolar star (Suen-Ki), with which are associated meridian observations of the solar shadows at the summer and winter solstices, has been shown by the Chinese astronomer Kao-Kiun (formerly of the Zo-se Observatory, near Shanghai) to correspond with the date 700 B.C.

 

Consistency??? Is 1200BCE 1200BCEor700BCE???

“Chou Kung, brother of Wu Wang (founder of the Chou dynasty, about 1120 B.C.)”

 

Ditto II:

“an earlier date, probably about 1120 B.C. ”

 

Treasure re length of year at time of earliest Chinese records:

“In the earliest part of the Chou-Pei where Chou Kung receives instructions from the grand prefect, Chang-Kao, it is stated that “the sky is measured in degrees.” The Chinese divided the circle into 365¼ degrees, each degree corresponding to the amount of the mean daily motion of the sun in the year. ”

 

Treasure re earliest Chinese ecliptic in 1200 BCE vs. 700 BCE:

“the obliquity of the ecliptic at the earliest date of the Chou Pei (about 1120 B.C.) as 24 degrees 12 minutes 6 seconds.”

 

ErrTreasure re latitude of location where ecliptic was measured in 1200 BCE vs. 700 BCE:

“1120 B.C. and were made at the ancient Chinese capital city of Mo. This city was situated on the western bank of the River Hoang-ho, in about latitude 35° 35’ N.  and longitude 115° 40’ E”

 

Treasure re earliest Chinese corrected ecliptic in 1200 BCE vs. 700 BCE:

 “When these corrections are applied, the corrected obliquity of the ecliptic, given by the Chou Pei for about 1120 B.C., is 24 degrees 13 minutes 56 seconds. This is 24 minutes 17 seconds greater than the obliquity given by Newcomb’s Formula for the same date.”

 

Err re consistency re 1200 vs 700 BCE:

“a real difference between the actually observed obliquity of the ecliptic at the date 1120 B.C.”

 

Treasure re ecliptic in 700 BCE – apparently later than the 1200 vs 700 BCE measurement:

“the ecliptic  24° 1’ 58”. This is 15’ 8” greater than the value for 700 B.C., calculated from Newcomb’s Formula… intermediate between the Chou Pei value for 1120 B.C. and the later series of Chinese observations…”

 

Err re 1200 vs 700 BCE in table:

“1120 B.C.”

 

Treasure re a 2nd very early ecliptic measurement:

“the obliquity 23° 54’ 4”), associated by Chinese tradition with the name of Chou Kung. These shadow lengths are found in the Chou Li  (Book of Rites)”

 

Treasure re Chinese confusion – evidence perhaps of confusion in the eyes of the beholders???:

“The Chinese astronomer…”

 

 

 

Chapter 4:

 

 

Treasure Reference:

“The earliest record of the obliquity of the ecliptic, determined by the ancient Hindus, is described by C.P.S. Menon in his book Early Astronomy and Cosmology.  It is taken from the Jaina Astronomical Treatise called Suryaprajnapti. ”

 

Typo:

“SZ   =    180 [x √2]    =    254.556 yojanas.
ZW =    330
[x √2]    =    486.642 yojanas. ”

 

Treasure references II & III:

“Brennand’s Hindu Astronomy”

“Bentley, in his Hindu Astronomy”

 

Treasure Hindu ecliptic measurements:

“The  obliquity of the ecliptic, thus determined, after correcting for refraction and solar parallax is 24° 11’ 4”

“the final result is 24° 00’ 44”

 

 

Re latitude:

Typo: “And for the latitude of the place of observation: 
Latitude  =   8°  18′  32″   N.
”  [Note: Like correction 6°  18′  32″   N]

“The latitude of the first place of observation, for which the shadow lengths at both solstices are available, is 6° 18’ 32” North.  This indicates a place…”

“The second place of observation:  Only one observation, namely that of the winter solstice, is given.  We can use this, however, to calculate the latitude.  The statement of the observation gives room for two alternative sites.  One of these is in latitude 20° 15’ 04” North, 14 miles south of Cuttack, near the top of Bay of Bengal; and the other is in latitude 10° 33’ 41” N, corresponding with the latitude of Trichur, 10° 32’ N, in the Cochin Province of S.W. India.  This place is the more likely, as it would only require a short coastal expedition to southern Ceylon.”

“The figures given in the Suryaprajnapti refer to two places where observations were made.  In addition to the obliquity of the ecliptic at the date of observation, the latitude of the sites of the observations can also be calculated. (Fig. 8)”  [Note: - Alternatively, could this indicate one place and a change in latitude???]

“a notable revision of astronomy was made about 945 B.C.” [Note: - “Revision of astronomy…” a reference to a catastrophic change in latitude??? ]

The site of the observations is believed to be Hastina Pura, the ancient seat of government in India, in latitude 28° 38’N , a few miles south of Delhi.

 

 

“Date of observations:  about 945 B.C.”

“The Suryaprajnapti is said to have been written “sometime about the 5th century B.C., but the cosmological system described in the work apart from a few incongruous elements added to it, is certainly of a much earlier date, some time in remote antiquity when men had not yet begun to regard the circle as the perfect curve, or as providing a scale of angular measurement.” ”

“ “it was found by observation that the Colures (1)had fallen back in respect of the fixed stars 30° 20’ since the former observations in 1192 B.C.”

This movement is consistent with the earth’s precessional movement in the interval of 247 years, and it is further stated that “In the same period of 247 years and one month they found that the moon had made 3303 revolutions, and one sign over, that there were also 3056 lunations of synodic periods, and the number of days in the whole period was 90245.5.” ” [Note: - Wrong year?, but correct interval???]

“It is understood, from its own statements, to have been compiled at the end of the period known as the Trita Yuga, and to embody the science of astronomy as it was at that time; certain changes having been made since more ancient times.
The end of the Trita Yuga corresponds to 510 B.C.
