    Joining The Dots

    I have now published my new book, Joining The Dots, which offers a fresh look at the Atlantis mystery. I have addressed the critical questions of when, where and who, using Plato’s own words, tempered with some critical thinking and a modicum of common sense.Read More »

Geomythology is a word coined by the geologist Dorothy Vitaliano in her 1973 book Legends of the Earth[306] to describe the study of alleged references to geological events in mythology.”

Since then, the term has gradually gained widespread acceptance including an extensive entry in the Encyclopedia of Geology(a).  The status of the subject has been consolidated by its inclusion as a separate course at the University of Puget Sound(b). Apart from Vitaliano other writers, such as Gerald Wells, have applied geomythology to the study of Atlantis without necessarily using the term(e). I should point out that mythology is also used to transmit details of spectacular astronomical events as well as more mundane political or military exploits.

Further support for the young discipline came with the publication of Myth and Geology by the Geological Society of London in 2007, with Luigi Piccardi & Bruce Masse as editors[1541].

Patrick Nunn, an Australian geologist, who although an Atlantis sceptic has begun to reconsider the possibility of ancient myths containing important geological information(c).>A May 2021 paper by Nunn gave examples of where the application of geomythology has offered solutions to some old mysteries(g).<

Also in May 2021, the BBC offered a lengthy paper, by Mark Piesing, on the development of geomythology in recent years and how it may have implications for our planet’s future(f).

Cindy Clendenon, presumably inspired by Vitaliano, has launched a related new specialised field of study, which she has named ‘hydromythology’ in her 2009 book, Hydromythology and the Ancient Greek World [0801], a review of which is available online(d).

Vitaliano, Dorothy B.

VitalianoDorothy B. Vitaliano (1916-2008) was a geologist who published Legends of the Earth in 1973[0306] in which she discussed how catastrophic seismic or volcanic events were retained for posterity in the legends of the peoples who experienced them. She invented the term ‘geomythology’ to describe what she considered to be a distinct field of study.

Probably inspired by Vitaliano, Cindy Clendenon has promoted a new related field of study(c) that she calls ‘hydromythology’[0801].

Vitaliano’s book included a chapter on Atlantis in which she expresses her opinion that there is nowhere in the Atlantic Ocean that Atlantis could have existed. Understandably, sceptics of an Atlantic Atlantis seized upon this statement, while those that adhere to the idea that it had been a large island in that ocean were understandably dismayed. Vitaliano also discussed the biblical Plagues of Egypt and their connection with the eruption of Thera in the second millennium BC.

Dorothy’s husband, Charles J. Vitaliano (1910-2000) was also a professor of geology and together they pursued the study of major geological events and their effect on ancient cultures.

There are two of Vitaliano’s papers that are available online(a)(b)as well as some sample pages from her book(d) and a short review (e).

Factor Ten

Factor Ten is a term I have employed to describe the fact that so many of the numbers in Plato’s Atlantis story, referring to time, physical dimensions and population all appear to be exaggerations, but would be more credible if reduced by a factor of ten. The date of 9600 BC for a war between Atlantis and Athens is not compatible with the Bronze Age description given by Plato, the dimensions of the canals in the city of Atlantis suggest a profligate degree of over-engineering and the size of the Atlantean army, as recorded, is comparable to the numerical strength of today’s USA’s military. On top of that, there is no archaeological evidence to support the idea of Athens having anything more than a Stone Age culture in the 10th millennium BC.

Dr A. G. Galanopoulos, who spent years excavating on Santorini, alsosuggested that all numbers in the thousands in Plato’s text were exaggerated, during translation, by a factor of ten. One can be forgiven for thinking that he was prompted to do this in order to match Atlantis to the timeframe of the Theran eruption, which occurred about 900 years before Solon’s Egyptian trip. However, J. V. Luce and Dorothy Vitaliano have refuted this idea.

A more frequently suggested explanation for the conflict between the 9,000 years given by Plato and the Bronze Age backdrop is that a lunar rather than a solar calendar was utilised by the Egyptian priests which would bring the two elements more into phase. So perhaps ‘Factor Twelve’ might be a more appropriate appellation.

Eudoxus of Cnidos (c.408-355 BC) who also studied astronomy with the priests of Heliopolis in Greece was one of the first to suggest that the Ancient Egyptians used lunar cycles to measure time. The idea was later endorsed by the Egyptian priest Manetho, Plutarch and Diodorus Siculus. Centuries later, Francisco Cervantes de Salazar (1514-1575) in his Crónica de la Nueva España[1517] he was a firm supporter of the idea of interpreting Plato’s 9,000 ‘years’ as lunar cycles, echoing the earlier statement of Eudoxus.*A year later Olof Rudbeck proposed the same explanation.*

However, while the substitution of solar years with lunar cycles would give a date for the Atlantean war that is more compatible with conventional archaeology, it still leaves the apparently inflated dimensions and military numbers recorded by Plato, unexplained. Since all of Plato’s numbers, in the Atlantis narrative appear to be overstated by a similar amount  it would seem appropriate to invoke the application of Occam’s Razor(c), which leads to an exaggeration by a factor of ten as the most likely explanation!

The use of lunar rather than solar units might explain the unrealistic ages ascribed to biblical characters such as Adam, Methuselah, or Noah although close study does not address all the difficulties. Similar problems exist with the length of the reign of individual  Sumerian kings. My belief is that a common explanation will eventually be found to rationalise both sets of anomalies. The answer will probably include the application of the Sumerian use of a numeric base of 60, coupled with lunar, solar and the Egyptian use of three seasonal ‘years’ per solar year. Zoltán Simon has claimed that the ages of the patriarchs were calculated using 90-day ‘years’[0549.7].

A number of suggestions have been put forward to explain how Plato’s exaggerated numbers came to be. Georgeos Diaz-Montexanocontends that it was not any confusion over hieroglyphics that led to the a tenfold exaggeration of numbers but the fact that in the spoken language of the Egyptians 100 and 1000 can be easily confused.

What may be of relevance is the fact that the Cretan scripts known as Linear A and Linear B use similar numbering signs. The number 100 is designated by a circle whereas 1000 is a circle with four nipples known as excrescences at the cardinal points. Both James Mavor and Rodney Castleden have advocated the idea that it was a misreading of these Minoan numerals that led to Plato recording hundreds as ‘thousands’.

Another reason for considering a factor ten error in Plato’s numbers may be drawn from the Chicago Demotic Dictionary, which has been developed over the past three decades at the Oriental Institute of the University of Chicago. It is edited by Professor Janet H. Johnson and is concerned with the ancient Egyptian cursive script in use from circa 650 BC, which is around the time of Solon, until the 5th century AD. Their website reveals that the cursive numerals for hundreds only differ from thousands by having longer tails(b) . I note that Johnson also records “that thousands sometimes had longer tails than expected”(p.23). This offers another credible explanation for how a transcription error could increase numbers by a factor of ten, which would bring Plato’s dates into conformity with other details in his Atlantis story, namely the Bronze Age milieu so clearly described there.

I also note that the Greeks had no zero or decimal point in their number system, making this kind of tenfold mistake quite a credible one(a).
