 Ptolemy Summary
Ptolemy's is a geocentric system, though the earth is the actual center only of the sphere of the fixed stars and of the "crank mechanism" of the moon; the orbits of all the other planets are slightly eccentric.
Ptolemy thus hypothesizes a mathematical system which cannot be made to agree with the rules of Aristotelian physics, which require that the center of the earth be the center of all celestial circular motions.
Ptolemy was the author of several scientific treatises, three of which have been of continuing importance to later Islamic and European science.

 Chronology - The Key to Prophetic Understanding - Part 2
He hedges in Ptolemy's canon of kings with an aura of authority that all other chronological systems must be judged by Ptolemy, and to Prideaux that included the chronology of the Bible itself.
If Ptolemy were correct -- that is, infallible, as suggested by so many historians -- then some of these eclipses observed by the ancients should have found a place on his table of eclipses.
Ptolemy was one of the very persons who had to deal with those obvious contradictions.

 Astronomical Dating
However, out of all the eclipse data that Ptolemy provides only one extant document matches the eclipse and year number with the data listed in his canon, and that is a copy made during the Seleucid period dealing with an eclipse in the seventh year of Kambyses.
Ptolemy (or one of his predecessors) would have had no trouble picking an eclipse for what was thought to be the ascension year of Nabonassar; then it would have been a simple matter to construct a chronology from that date by aligning eclipse records with year numbers based on king lists available at that time.
Ptolemy lists the eclipse in the fifth year of Nabopolassar as occurring on 22 April, 621, but this is another eclipse that Newton concluded was fabricated, and, once again, there can be no certainty about the year number.

 Ptolemy - Wikipedia, the free encyclopedia
The universe of Ptolemy is a diagram of the relationships existing between the various divine and elemental parts of every creature, and is not concerned with astronomy as that science is now comprehended.
Ptolemy's scheme of the universe is a cross section of the universal aura, the planets and elements to which he refers having no relation to those recognized by modern astronomers." (source:http://prs.org/gallery-classic.htm).
After criticizing the approaches of his predecessors, Ptolemy argued for basing musical intervals on mathematical ratios (in contrast to the followers of Aristoxenus and in agreement with the followers of Pythagoras) backed up by empirical observation (in contrast to the overly-theoretical approach of the Pythagoreans).

 Ptolemy's Canon   (Site not responding. Last check: 2007-10-08)
Ptolemy's Canon: list of rulers of ancient Babylonia and the Near East, used by the astronomer Ptolemy of Alexandria to date astronomical phenomena.
The astronomer Ptolemy of Alexandria, who lived in the second century CE, used the system of regnal years and has handed down to us an important list of kings.
Because they were only interested in dating astronomical phenomena, kings who died during a certain year were usually allowed to give their name to the entire year, and the next ruler is supposed to have ascended to the Babylonian throne on the first day of the new year.

 Appendix A. The Scientific Basis of Prophetic Chronology
Ptolemy’s great work, the "Almagest," is a treatise on astronomy, setting forth the researches of ancient observers and mathematicians with reference to the position of the stars, the exact length.
That Ptolemy was its author and not Theon, is confirmed by the fact that it is not continued beyond Antoninus, in whose reign our author dates most of his observations.
The Evil-merodach of Scripture corresponds with the Ilvarodamus of the Canon of Ptolemy, and the interval from the eighth year of Nabokolassar to the first year of his successor, Ilvarodamus, includes in the Canon a period of thirty-seven years.

A second son Ptolemy was sent as an ambassador to Philip V of Macedon in 204/3 (Polybius 15.25.13).
Ptolemy VI to Antiochus IV in 169 (Polybius 28.19.6).
Ptolemy VI was accounted as beginning in the 24th Macedonian regnal year of Ptolemy V. He does not present any justification for the choice, and does not recognise the discrepancy in the two versions of Eusebius; moreover the inference he draws is very questionable, though not impossible.

PTOLEMY'S Canon (cent.2 A.D.) is to CLINTON and his disciples what the monuments are to PROFESSOR SAYCE and his followers.
Grecian chronology is the basis of "PTOLEMY'S Canon"; and, if his foundations are "suspect", and this is certainly the case, then the elaborate superstructure reared upon them must necessarily be regarded with suspicion likewise.
Now, to-day, we have what is called "the Witness of the Monuments", of which it may be remarked that frequently their testimony is accepted in preference to the scriptural record, and is often used to impugn the statements and chronology of the Bible.

 The Development of the Canon of the New Testament - Valentinus
Valentinus was the founder of Roman and Alexandrian schools of Gnosticism, an eclectic, dualistic system of religious doctrines postulating the evil origin of matter and the revelatory enlightenment, or gnosis, of an elite.
The Valentinian system developed into Eastern and Western forms in greater complexity, although the earlier structure was similar to Pauline mystical theology, with its emphasis on the instrumentality of Christ's death and resurrection in effecting Christian deliverance.
Ptolemy, a disciple of Valentinus, is known as the author of an open letter to a wealthy and eminent Christian lady, Flora by name, whom he tries to convert to the Valentinian system.

 Ptolemy VIII
He is also sometimes numbered as Ptolemy VII and Ptolemy IX, depending on the convention used to number Ptolemy Eupator and Ptolemy Neos Philopator.
The Canon of Ptolemy gives Ptolemy VIII 29 years after Ptolemy VI, from which the year of his death is 117/6.
For Strack's suggestion that Ptolemy Neos Philopator was a younger brother of Ptolemy Memphites by Cleopatra II, or the eldest son of Cleopatra III, see discussion under Ptolemy Memphites.

 Chapter 1: CONCLUSION (SOTHIC DATING)
How Ptolemy came across documents containing such information is uncertain, but his interest in them lay mainly in their astronomical content.
In 1978, astronomer Robert Newton published a study entitled The Crime of Claudius Ptolemy (Baltimore: Johns Hopkins Press, 1977), in which he claimed that Ptolemy had faked his astronomical data; that is, Ptolemy had calculated when these lunar and solar eclipses should have taken place, and had put them into his chronology.
Both Mitchell and James argue that Ptolemy's King List — a backbone of later ancient world chronology — is correct because an eclipse noted by the Assyrian King List, assumed to have been visible at Nineveh (the capital), happened in 763 BC during the reign of the king Ptolemy says ruled at that time.

 Chronological Falsehoods
Ptolemy was accepted as infallible because he mentioned seven lunar eclipses that occurred within the late Assyrian, Neo-Babylonian and Persian periods.
This year is dated to 585 B.C. by the Canon of Ptolemy (scholars have manipulated the date and have stretched to be either 586 or 587 B.C.).
If Ptolemy were correct—that is, infallible, as suggested by the modern historians—then all these eclipses observed by the ancients would find a certain place on his table of eclipse cycles.

Like Aristarchus, Eratosthenes, and Hipparchus, Ptolemy of Alexandria was interested in both geography and astronomy.
It is a summary of all astronomical knowledge of his age, and it remained the most important work on this subject until the sixteenth century, especially because he gave mathematical explanations of the phenomena.
To get a grip on the chronology of the preceding nine centuries, he used a chronological system that is called the Canon.

They were not obtained with the instrument that Ptolemy claims to have used, they were not obtained by the method that he claims to have used, and they were not obtained by any other instrument or procedure of observation.
He sees that Ptolemy dates a lunar eclipse in the first year of Mardokempad, for example, on a certain month and day in the Egyptian calendar, at a certain hour on that day, and he states the fraction of the moon that was shadowed during the eclipse.
Ptolemy certainly fabricated many of the aspects of the lunar eclipses, and he may have fabricated all of them.

 The Fourth Year of Jehoiakim (Jer. 25:1-3)
If NEWTON was right, then it follows that the Canon of PTOLEMY, upon which the faith of modern chronologers is so implicitly -- almost pathetically -- pinned, must have been built upon unreliable foundations.
Grecian chronology is the basis of "PTOLEMY'S Canon"; and, if his foundations are "suspect", and this is certainly the case, then the elaborate super-structure reared upon them must necessarily be regarded with suspicion likewise.
In his turn, he is largely used by moderns to "determine" scriptural dates; and it is mainly through his instrumentality that many of the so-called "received" datings of the O.T., from Abraham to the Christian era, have been "fixed".

Upon this "canon" all modern chronologists have built their systems, and this for the simple reason that there is nothing else, apart from the Bible, for them to build on.
But Ptolemy is not a contemporary historian, for he lived about seven hundred years after the reign of Cyrus; nor does he refer to any contemporary historical records as authority for his statements.
Ptolemy had no means of determining the chronology of this period, so he made the best use of the materials he had, and contrived to make a chronology.

If the number drawn from the canon is equal to the number given by the pointer of the rete, degrees of the astrolabe is true; if there is a difference of two or three degrees it is evident that the astrolabe is untrue.
We can also find the ascensions by taking in Ptolemy's canon the number written in the second column opposite the degree which we have placed on the eastern horizon, in the proper climate which is occupying us.
For each climate we look for the sign and the degree that is occupying us, then we multiply the number of the degrees of an hour which is written opposite this degree by the six hours which go from the degree 'of life' to the middle of the heaven.

 Shaun's Research on the Jehovah's Witnesses
79-81, it was stated that ”Ptolemy’s forgery may have extended to inventing the length of reigns of Babylonian kings.” This was a reference to the so-called ”Ptolemy’s Canon”, which Newton at that time erroneously believed had been composed by Claudius Ptolemy himself and thus may have been affected by his ”forgery”.
Ptolemy’s supposed ”adjustments” of the records of the ancient Babylonian eclipses, then, didn’t change the BCE dates that had been established for these observations.
Further, the claim that Ptolemy may have ”invented” the lengths of reign in ”Ptolemy’s Canon” is based upon the mistake that this king list was composed by Claudius Ptolemy.

It follows that all who adopt Ptolemy's chronology, or any system based upon it (as all modern chronologists prior to Anstey do) would inevitably be led far astray.
But such references are of no value whatever for the purpose, seeing that it is impossible to determine, in any given case, which one of a number of eclipses- within say fifty or a hundred years- was the one referred to.
Nevertheless it is the favorite of certain learned expositors of our day, and for the very reason that it is the latest in date, and hence agrees best with the mistaken chronologies which have been derived from the canon of Ptolemy.

It is remarkable that the Egyptian Claudius Ptolemy (second century after Christ) took from the Babylonians and the Greeks all the observations of eclipses he ever used and started his canon (see above) with Babylonian, not with Egyptian kings.

 The Development of the Canon of the New Testament - Authorities
An early Christian authority is included in this survey if he or it gives important evidence on the development of the canon of the New Testament (perhaps even having some influence on it) and did so before ~400 CE, when the first complete manuscripts of the Vulgate were issued.
Valentinus and his followers - Heracleon, Ptolemy, Marcus - were Gnostic heretics so their doctrines mostly survive in the writings of the orthodox, such as Irenaeus, who summarized the Valentinian views before attacking them.
The Gospel of Truth from Nag Hammadi probably derives from the Valentinians, but this is not certain.

Clearly both of these cannot be correct, and the known inaccuracy of the Suda led historians to favour dates for Pappus which would have him writing in the period 284 AD - 305 AD, as suggested by the insertion into Theon's chronological table.
When Ptolemy in the chapter on the apparent diameter of the sun, moon and shadow simply remarks that the tangential cones in question contact the spheres within a negligible error in
Or, when Ptolemy says that some phenomenon cannot take place, neither for the same clima nor for different geographical latitudes, Pappus feels obliged to explain "same clima" by "either in clima 3, or in 4, or in any other clima", and to illustrate "different" by referring to "Rome or Alexandria".
