Ancient Chronology is a subject fraught with difficulties(a) as well as the focus of intense academic debate, particularly over the past half-century.
Archbishop Ussher (1581-1656) calculated the date of creation to have been October 23rd 4004 BC(d). Incredible as it may seem, even today (2019), there are still people prepared to give further consideration to his ideas (c)(e).
Sir Isaac Newton (1642-1727) became the first ‘modern’ revisionist of accepted ancient chronology. His work was heavily criticised and few serious advances were made until the development of Egyptology following Napoleon’s invasion of Egypt at the end of the 18th century.
Difficulties with details of Egyptian dating slowly accumulated, particularly when endeavouring to align it with Greek, Minoan and other Eastern chronologies. The scholarly debates became very public in the middle of the 20th century with the eventual publication of Ages in Chaos by Immanuel Velikovsky and the attempts made to suppress it altogether. The refining of Velikovsky’s theories followed, with important contributions by S. Talbott, Edward Schorr and John Bimson. Some, such as Emmet Sweeney, have accused Velikovsky of being over-dependent on his belief in the inerrancy of biblical chronology.
The Society for Interdisciplinary Studies (SIS)(b) was founded in 1974 and produces regular publications. This was followed a few years later by three important books by David Rohl and Centuries of Darkness  by Peter James, who also wrote The Sunken Kingdom in which he places Atlantis in Turkey. Rohl & James were in agreement on many details, but fell out over the identity of Shishak (was he Ramesses II or III?). However, prior to that, in the early 1980s, they had published a joint paper that gave the world a first look at their New Chronology. Rohl republished it in 2012(v).
On the occasion of the SIS Jubilee Conference in 1999 a paper by P. John Crowe was presented, which gave a valuable insight into historical revisionism before and after Velikovsky(a).
>Gunnar Heinsohn (1943-2023) was a Professor Emeritus at the University of Bremen but was also an ardent chronology revisionist,< concerned not just with the dating problems of the ancient world(l) but also with difficulties to be seen in the first millennium of the Common Era(m).
One of the most controversial aspects of Plato’s Atlantis story is the old Egyptian priest’s claim that Atlantis was destroyed 9,000 years before Solon’s visit. He also related that Athens, who fought the Atlanteans, was established one thousand years before the Egyptian state or as is more likely, before the foundation of the city of Sais. Apart from anachronisms in Plato’s narrative, the archaeological evidence completely contradicts the dates seemingly offered by the priests of Sais. It is interesting that most of the chronology revisionist debate centres on the second millennium BC which is arguably the most rational timeframe for the destruction of Atlantis based on the Bronze Age references in Timaeus and Critias, provided they are not just anachronistic embellishments.
I should also mention that while the debates regarding the Bronze Age chronologies rage on, further controversy has arisen regarding claims of duplicated centuries in the first millennium of our era. Leading the charge here are Anatoly Fomenko(k) , Heribert Illig(h)(i)(j) and Gunnar Heinsohn(g). A keen supporter of Fomenko’s work is Garry Kasparov the former World Chess Champion(p). A more critical view of Fomenko’s work is on offer from Stephen Sorensen(s).
Nathaniel Lloyd had written an extensive three-part paper on the history of chronological revisionism(t). This should be read in conjunction with a paper entitled The Glorious Stupidity of Fomenko’s New Chronology(u).
Up to this point, I have outlined some of the problems and theories concerning the accurate alignment of specific events with particular years. A clash of archaeology and accepted history, secular and religious. has generated libraries of debate. However, our problems do not end with the counting of years, but contention has also arisen over the length of the day before the seventh century BC. Evidence is available to show that there was a 360-day year in use around the world in those ancient times.
Some religious sites have proposed that before the Deluge we had a 365-day year, then it changed to 360 days and then reverted to the current 365.2422 days(q). By way of complete contrast Danny Faulkner, a creationist astronomer rejects the idea that the world was created with a 360-day year, although it is a view held by many creationists(r).
William Whiston was one of the first ‘modern’ commentators to conclude that in very ancient times a 360-day year was used(n). More recently, Immanuel Velikovsky devoted a chapter of Worlds in Collision to The Year of 360 Days(o). The Brit-Am movement endorsed Velikovsky’s views in this regard, as does William F. Drankenbring.

Immanuel Velikovsky (1895-1979) was born in what is now Belarus. He was by profession a doctor of medicine, specialising in psychiatry. However, his fame is based on being arguably the most controversial catastrophist of the 20th century. He daringly proposed that the Earth had several close encounters with other planetary bodies that resulted in catastrophic consequences, including interference with the rotation of our planet. He speculated that Atlantis was probably destroyed during one of these cataclysmic events.
John Kettler is an American writer on alternative science and was a frequent contributor to Atlantis Rising magazine. In issue #30(z) of that publication, he reviewed the disgusting manner in which members of the scientific community endeavoured to prevent the publication of Velikovsky’s books. In order to give you the full flavour of the nastiness of their methods, I add three paragraphs here.
“The scientific and academic reaction to the book (Worlds in Collision) was generally presaged by the extortion practised prior to and after publication against the Macmillan Company. As the book began to garner public and in some circles, even scientific interest and acclaim, all pretence of genteel discussion went by the boards. Out came the mailed fists, the naked threats and oceans of mud and offal. The attacks targeted three main groups: the public, the scientific and academic community, and Immanuel Velikovsky himself. Nor were such niceties as actually reading the book before denouncing it and its author employed.
Even before the Macmillan Company published the book, renowned astronomer Harlow Shapley arranged multiple intellectual well poisonings by an astronomer, a geologist, and an archaeologist, not one of whom had read the book, in a learned journal. This was a pattern used over and over again.
Shapley and his minions also engineered the sacking of the veteran senior editor (25 years at the Macmillan Company) who accepted Worlds in Collision for publication and got the director of the famous Hayden Planetarium fired for the high crime of proposing to mount a display there, on Velikovsky’s unique cosmological theory. Meanwhile, Velikovsky was systematically attacked in the scientific journals, via distortion, lies, misrepresentation, incompetence and ad hominem attacks, while there never seemed to be space in which he could reply, in order to defend himself.” J. Douglas Kenyon included Kettler’s revealing essay in Forbidden History [802.53].
Some have seen the influence of Ignatius Donnelly’s Ragnarok, written seventy years earlier, in Velikovsky’s cosmic collision theories. Some commentators have noted how Velikovsky seemed reluctant to credit earlier writers, such as W. C. Beaumont and Johann Radlof (1775-1846)(b), with their contributions to the development of the theory of planetary catastrophism. Rens Van Der Sluijs has written an interesting two-part paper(d)(e) listing the catastrophists who preceded Velikovsky demonstrating a certain lack of originality on his part! Others take a more critical view of his ideas(g). In 1950, he responded to this criticism with a defensive piece(n), but I consider it inadequate as he continued to ignore the work of Radlof and Beaumont. Some years ago Ev Cochrane and Phil ‘Pib’ Burns also discussed Velikovsky’s reluctance to credit earlier writers for ideas used by him, compared with the recognition given by Clube & Napier to the work of Velikovsky(x).
Van Der Sluijs has written a two-part(k)(l) article on Velikovsky’s radical views regarding Venus as a comet-like body and how Aztec sources support some of his contentions.
Carl Sagan (1934-1996), was a well-known American astronomer, author and lecturer. He is considered a leading debunker of Velikovsky’s theories. He devoted much of his Broca’s Brain  to this end. Charles Ginenthal (1934-2017) produced an extensive rebuttal of Sagan’s criticisms in Carl Sagan & Immanuel Velikovsky . However, criticism of Velikovsky continues with varying degrees of ferocity, such as that of Leroy Ellenberger, a former supporter of Velikovsky, who contends that the data from the Greenland ice cores fail to support Velikovsky(s).
Velikovsky and Einstein were acquaintances and as Nathaniel Lloyd wrote in his three-part blog on chronological revisionism(y) that when Velikovsky “asked Einstein to read his work and give an opinion. Einstein suggested that Velikovsky might have a hard time finding a publisher, specifically because “every sensible physicist” would realize that the catastrophes Velikovsky described would have completely destroyed the Earth’s crust. Nevertheless, Einstein was kind about his criticism, and Velikovsky was undeterred. But years later, in Einstein’s very last interview, his opinion was less delicate: ‘It really isn’t a bad book,’ he said, laughing. ‘The only trouble with it is, it is crazy’.”
Velikovsky was initially inclined to link the disappearance of Atlantis with the eruption of Thera but later came to support a location between the Azores and the Mid-Atlantic Ridge(i). He was an early questioner of Plato’s figure of 9,000 years for the age of Atlantis, suggesting that it was exaggerated by a factor of ten[0037.152]. ”Whatever the source of the error, the most probable date of the sinking of Atlantis would be in the middle of the second millennium, 900 years before Solon when the earth twice suffered great catastrophes as a result of ‘the shifting of the heavenly bodies.’ These words of Plato received the least attention, though they deserved the greatest.”
Velikovsky offered intriguing evidence that on at least one occasion the early Egyptians experienced the sun rising in the west and set in the east(q)!
His other major contribution was in his questioning of the accepted Bronze Age chronologies of the eastern Mediterranean. Later writers, such as David Rohl and Peter James have built on his chronology work, while Gary Gilligan has added support for Velikovsky’s planetary theories as well. Others have accused Velikovsky of being over-dependent on his belief in the inerrancy of biblical chronology.
In a recent (2023) paper(ac). on the Academia.edu website, Donald Keith Mills was highly critical of Velikovsky’s research on the Hyksos and Amalakites in Ages in Chaos. Mills had earlier written critically of Velikovsky’s Worlds in Collision(ab).
“In Ages in Chaos, Velikovsky made numerous detailed claims which he supported by footnote references to his sources. Those sources were of two kinds: those that would be easily available to most of his readers, such as the Bible and the works of Josephus; and those that would be difficult or impossible for most readers to access, including technical journals and the works of medieval Arabian, Persian, and Egyptian writers.
“Access to such materials began to change in the late 20th Century, and I have been able to download almost all of Velikovsky’s “Arabic” sources from the Internet Archive Digital Library (https://archive.org/ ), together with some he didn’t explicitly use. Those original sources, in the same editions as he cited, revealed that his uses of allusions, references, and quotations often failed to agree with what the sources actually said.”
“Repeatedly, when faced with conflicting accounts of pre-Islamic (and essentially prehistoric) events, Velikovsky selected only those that met his purposes. The damaging aspect of this criticism is the fact that, almost without exception, he did so without discussing the alternatives, without providing reasons for rejecting them, and without even acknowledging their existence.“
One website(a)provides us with a considerable amount of Velikovsky’s unpublished work, while another offers an encyclopedia of his work(c). A more general German site(f), in English, is also worth a visit.
The three of Velikovsky’s most popular books as well as some of his lesser-known papers are available as pdf files(j)(m).
Jan Sammer was an assistant to Velikovsky (1976-1978) and an archivist and editor for the Velikovsky Estate (1980-1983). He advises us that he was involved in the completion of Velikovsky’s unpublished book, In the Beginning(h), which was eventually published in 2020 . The book’s contents were originally intended to be part of Worlds in Collision. In it, you will find more details of Velikovsky’s claim that within the memory of man, there was a time when we had no Moon, which he claimed was subsequently ‘captured’ by the Earth. He wrote a short paper in 1973 entitled Earth without a Moon and published by the editors of Pensée in Velikovsky Reconsidered [1877.86], but without any reference to Hanns Hörbiger.
According to Velikovsky, Venus was a relatively recent newcomer to our Solar System and the orbit of Mars had been disturbed, which would suggest that before the arrival of Venus, Bode’s Law would have been invalidated! C.J. Ransom tackled this head-on in The Age of Velikovsky [1880.90]. However, his defence of Bode and Velikovsky was rejected by Dr M. M. Nieto(t).
In 2012, Laird Scranton, published The Velikovsky Heresies, in which he reviews Velikovsky’s controversial theories in the light of scientific discoveries since his death. Not unexpectedly, Scranton does find evidence that supports some of Velikovsky’s contentions.
Ralph E. Juergens, an American engineer, supported Velikovsky with the idea that electromagnetic and electrostatic forces and not conventional celestial mechanics alone were responsible for the cosmic encounters witnessed and recorded by our ancestors(u).
In the late 1990s Sean Mewhinney (1944-2016), a Canadian researcher published a series of papers(w) that was highly critical of Velikovsky’s theories. Much of his criticism was focused on ice-core data. Once again, Charles Ginenthal took up the challenge, responding with an extensive paper entitled Minds in Denial, later the title of an ebook  that include the original paper. Ginenthal also published a book on the Electro-Gravitic Theory of Celestial Motion and Cosmology and its possible application to Velikovsky’s theories(v).
In 2021, Bob Forrest(aa), a British retired mathematics teacher had re-published a book of over 700 pages entitled Velikovsky’s Sources, which deals with Worlds in Collision. It had been originally issued as a series of seven booklets between 1981 and 1985. These have now been combined in one volume and edited by Donald Keith Mills and available on the Academia.edu website(ab). The content is a critique of Velikovsky’s work and now forty years later Forrest still believes “that Velikovsky was spectacularly wrong.”
Some readers may wish to see a video by Wallace Thornhill, of Electric Universe fame, in which he discusses Velikovsky’s Astrophysics(o). There are several related papers and books, including some Velikovskian material, freely available online(p).
