An A-Z Guide To The Search For Plato's Atlantis


Joining The Dots

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.

Hanno, The Voyage of

The Voyage of Hanno, the Carthaginian navigator, was undertaken around 500 BC. The general consensus is that his journey took him through the Strait of Gibraltar and along part of the west coast of Africa. A record, or periplus, of the voyage was inscribed on tablets and displayed in the Temple of Baal at Carthage. Richard Hennig Hannospeculated that the contents of the periplus were copied by the Greek historian, Polybius, after the Romans captured Carthage. It did not surface again until the 10th century when a copy, in Greek, was discovered (Codex Heildelbergensis 398) and was not widely published until the 16th century.

The 1797 English translation of the periplus by Thomas Falconer along with the original Greek text can be downloaded or read online(h).

Edmund Marsden Goldsmid (1849-?) published a translation of A Treatise On Foreign Languages and Unknown Islands[1348] by Peter Albinus. In footnotes on page 39 he describes Hanno’s periplus as ‘apocryphal’. A number of other commentators(c)(d) have also cast doubts on the authenticity of the Hanno text.

Three years after Ignatius Donnelly published Atlantis, Lord Arundell of Wardour published The Secret of Plato’s Atlantis[0648] intended as a rebuttal of Donnelly’s groundbreaking book. The ‘secret’ referred to in the title is that Plato’s Atlantis story is based on the account we have of the Voyage of Hanno.

Nicolai Zhirov speculated that Hanno may have witnessed ‘the destruction of the southern remnants of Atlantis’, based on some of his descriptions.

Rhys Carpenter commented that ”The modern literature about his (Hanno’s) voyage is unexpectedly large. But it is so filled with disagreement that to summarize it with any thoroughness would be to annul its effectiveness, as the variant opinions would cancel each other out”[221.86].

Further discussion of the text and topography encountered by Hanno can be read in a paper[1483] by Duane W. Roller.

What I find interesting is that so much attention was given to Hanno’s voyage as if it was unique and not what you would expect if Atlantic travel was as commonplace at that time, as many ‘alternative’ history writers claim.

However, even more questionable is the description of Hanno sailing off “with a fleet of sixty fifty-oared ships, and a large number of men and women to the number of thirty thousand, and with wheat and other provisions.” The problem with this is that the 50-oared ships would have been penteconters, which had limited room for much more than the oarsmen. If we include the crew, an additional 450 persons per ship would have been impossible, in fact it, is unlikely that even the provisions for 500 hundred people could have been accommodated!

Lionel Casson, the author of The Ancient Mariners[1193] commented that “if the whole expedition had been put aboard sixty penteconters, the ships would have quietly settled on the harbour bottom instead of leaving Carthage: a penteconter barely had room to carry a few days’ provisions for its crew, to say nothing of a load of passengers with all the equipment they needed to start a life in a colony.

The American writer, William H. Russeth, commented(f) on the various interpretations of Hanno’s route, noting that “It is hard for modern scholars to figure out exactly where Hanno traveled, because descriptions changed with each version of the original document and place names change as different cultures exert their influence over the various regions. Even Pliny the Elder, the famous Roman Historian, complained of writers committing errors and adding their own descriptions concerning Hanno’s journey, a bit ironic considering that Romans leveled the temple of Ba’al losing the famous plaque forever.”

George Sarantitis has a more radical interpretation of Hanno’s journey, proposing

Hanno's possible route according to Sarantitis

Hanno’s possible inland route according to Sarantitis

(e) that instead of taking a route along the North African coast and then out into the Atlantic, he proposes that Hanno travelled inland along waterways that no longer exist. He insists that the location of the Pillars of Heracles, as referred to in the narrative, matches the Gulf of Gabes.

The most recent commentary on Hanno’s voyage is on offer from Antonio Usai in his 2014 The Pillars of Hercules in Aristotle’s Ecumene[980]. He also has a controversial view of Hanno’s account, claiming that in the “second part, Hanno makes up everything because he does not want to continue that voyage.” (p.24) However, the main objective of Usai’s essays is to demonstrate that the Pillars of Hercules were originally situated in the Central Mediterranean between eastern Tunisia and its Kerkennah Islands.

A 1912 English translation of the text can be read online(a).

Another Carthaginian voyager, Himilco, is also thought to have travelled northward in the Atlantic and possibly reached Ireland, referred to as ‘isola sacra’. Unfortunately, his account is no longer available(g).

The website offers three articles(i) on the text, history and credibility of the surviving periplus together with a commentary.

Syrtis was the name given by the Romans to two gulfs off the North African coast; Syrtis Major which is now known as the Gulf of Sidra off Libya and Syrtis Minor, known today as the Gulf of Gabes in Tunisian waters. They are both shallow sandy gulfs that have been feared from ancient times by mariners. In the Acts of the Apostles (Acts 27.13-18) it is described how St. Paul on his way to Rome was blown off course and feared that they would run aground on ‘Syrtis sands.’

However, they were shipwrecked on Malta or as some claim on Mljet in the Adriatic.

The earliest modern reference to these gulfs that I can find in connection with Atlantis was by Nicolas Fréret in the 18th century when he proposed that Atlantis may have been situated in Syrtis Major. Giorgio Grongnet de Vasse expressed a similar view around the same time. Since then there has been little support for the idea until recent times when Winfried Huf designated Syrtis Major as one of his five divisions of the Atlantean Empire.

However, the region around the Gulf of Gabes has been more persistently associated with aspects of the Atlantis story. Inland from Gabes are the chotts, which were at one time connected to the Mediterranean and considered to have been part of the legendary Lake Tritonis, sometimes suggested as the actual location of Atlantis.

In the Gulf itself, Apollonius of Rhodes placed the Pillars of Herakles(a) , while Anton Mifsud has drawn attention[0209] to the writings of the Greek author, Palefatus of Paros, who stated (c. 32) that the Columns of Heracles were located close to the island of Kerkennah at the western end of Syrtis Minor. Lucanus, the Latin poet, located the Strait of Heracles in Syrtis Minor. Mifsud has pointed out that this reference has been omitted from modern translations of Lucanus’ work!

Férréol Butavand was one of the first modern commentators to locate Atlantis in the Gulf of Gabés[0205]. In 1929 Dr. Paul Borchardt, the German geographer, claimed to have located Atlantis between the chotts and the Gulf, while more recently Alberto Arecchi placed Atlantis in the Gulf when sea levels were lower(b) . George Sarantitis places the ‘Pillars’ near Gabes and Atlantis itself inland, further west in Mauritania, south of the Atlas Mountains. Antonio Usai also places the ‘Pillars’ in the Gulf of Gabes.

In 2018, Charles A. Rogers published a paper(c) on the website in which he identified Tunisia as Atlantis with it capital located at the mouth of the Triton River on the Gulf of Gabes. He favours Plato’s 9.000 ‘years’ to have been lunar cycles, bringing the destruction of Atlantis into the middle of the second millennium BC and coinciding with the eruption of Thera which created a tsunami that ran across the Mediterranean destroying the city with the run-up and its subsequent backwash. This partly agrees with my conclusions in Joining the Dots!

Usai, Antonio

Antonio Usai (1957- ) was born in Assemini, 12km northwest of Cagliari, the capital of Sardinia. Having a passion for ancient  UsaiAntoniohistory, he has written a number of papers(a) locating the Pillars of Heracles within the Mediterranean. An English translation of The Pillars of Hercules in Aristotle’s Ecumene is now available on the excellent website as well as a 67-page booklet[0980]. Included in his work is a critique(b) of Sergio Frau’s book[302].

Usai followed a reading of Frau’s book with a study of the works of Herodotus, Aristotle, Polybius and Strabo among others. He was drawn to the story of Hanno’s voyage, where Hanno ls described as leaving Carthage, turning east, then passing through the ‘Pillars’ and following the coast south towards Syrtis Minor, which is described as being on their right.

According to Usai, this would only make sense if the Pillars had been situated between the east coast of Tunisia and the islands of Kerkennah. Furthermore, Usai contends that part of Hanno’s report of his voyage was a hoax!

Finally, after devoting most of his essays to identifying the original Pillars at Kerkennah, he concludes his work by identifying Greenland as the location of Atlantis.

A number of translations of the Periplus (Sea Voyage Guide) of Hanno are available on the internet(d).

Identity of the Atlanteans (m)

The Identity of the Atlanteans has produced a range of speculative suggestions nearly as extensive as that of the proposed locations for Plato’s lost island. However, it is highly probable that we already know who the Atlanteans were, but under a different name.

The list below includes some of the more popular suggestions and as such is not necessarily exhaustive. While researchers have proposed particular locations for Atlantis, not all have identified an archaeologically identified culture to go with their chosen location. The problem being that most of the places suggested have endured successive invasions over the millennia by different peoples.

It would seem therefore that the most fruitful approach to solving the problem of identifying the Atlanteans would be to first focus on trying to determine the date of the demise of Atlantis. This should reduce the number of possible candidates, making it easier to identify the Atlanteans.

A final point to consider, is that the historical Atlanteans were a military alliance, and as such may have included more than one or none of those listed here. The mythological Atlanteans, who included the five sets of male twins and their successors would be expected to share a common culture, wheras military coalitions are frequently more disparate.

Greenland was first proposed as the location of Atlantis in the 17th century by François de la Mothe le Vayer. More recently some of the more imaginative writers have tried, unsuccessfully, to revive interest in Huffman_greenland_1_230this idea. One of these is the American, Dale Huffman, who claims that the outline of Greenland is comparable with Kircher‘s famous map of Atlantis. He has also proposed that while Atlantis was primarily Greenland it also included the islands of the United Kingdom and Iceland”(h).(see left)

Another proponent is Mario Dantas who is equally determined to link Plato’s description with the enormous island of Greenland(a) and has submitted a paper on the subject to the 2008 Atlantis Conference in Athens.

Another site(b) advocates the Baffin Basin just west of Greenland, as the Great Plain of Atlantis. This idea developed by a New Zealander, Ian Fox, is based on a re-interpretation of Plato’s text combined with the studies of Charles Hapgood.

In 2014, Antonio Usai published an English translation of his 2011 booklet on the Pillars of Hercules[980]  in which he places the original ‘Pillars’ at the Tunisian island of Kerkennah and then unexpectedly proposed that Atlantis was situated at Greenland.

Another proponent of the Greenland location is Stefan Grossmann in his book, Atlantlantean(sic) Philosophy(d), a commentary on the non-existent ‘Emerald Tablets of Thoth’(e), concocted by Maurice Doreal (Claude Doggins).

In October 2011 a team of researchers from the Laboratory of Geology in Lyon may have elevated the importance of Greenland to an even higher level with their claim(c) that life on earth may have originated there 3.8 billion years ago.

In 2013, Lucio Russo, an Italian mathematician and science historian, located Thule on the coast of Greenland, having identified errors in Ptolemy’s geographical calculations[1060].

In 2014 Antonio Moreno Checa published La Atlántida. El mito hecho realidad (Atlantis. The myth comes true)[1063] in which he also locates Atlantis in Greenland. Gennaro Anziano, an Italian writer, has also located Atlantis in Greenland(g) in his 2001 book, Atlantis – Discover the land of the gods[1072].

Marco Goti published The Island of Plato[1430] in 2017 and offered another failed attempt at identifying Greenland as Atlantis.

Leaving aside any suggested connection with Atlantis, there are other features of the vast island that deserve attention. There are a number of raised beaches which clearly indicate that “the whole of this large island has been raised, or the sea has sunk, in post-glacial times” and that “the upheaval has been greater in the north”. Their height above sea level varies from 325 and 480 feet!
