    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 »

Concentric Rings

The Concentric Rings or other architectural features extracted by artists from Plato’s description of the capital of Atlantis have concentric circlescontinually fascinated students of the story and many have attempted to link them with similar ancient features found elsewhere in the world as evidence of a widespread culture. Stonehenge, Old Owstrey, Carthage and Syracuse have all been suggested, but such comparisons have never been convincing. Diaz-Montexano has recently published(a) an image of a fragment of pottery found near Seville in Spain that shows concentric circles and insists that it is a symbol of Atlantis. Ulf Erlingsson has made a similar claim regarding some concentric circles carved on a stone basin found at Newgrange in Ireland.

Less well-known are the concentric stone circles that are to be found on the island of Lampedusa in the Strait of Sicily(b).

In 1969 two commercial pilots, Robert Brush and Trigg Adams photographed a series of large concentric circles in about three feet of water off the coast of Andros in the Bahamas. Estimates of the diameter of the circles range from 100 to 1,000 feet. Apparently, these rings are now covered by sand. It is hard to understand how such a feature in such very shallow water cannot be physically located and inspected. Richard Wingate in his book[0059] estimated the diameter at 1,000 yards. However, the rings described by Wingate were apparently on land, among Andros’ many swamps.

Two papers presented to the 2005 Atlantis Conference on Melos describe how an asteroid impact could produce similar concentric rings, which, if located close to a coast, could be converted easily to a series of canals for seagoing vessels. The authors, Filippos Tsikalas, V.V. Shuvavlov and Stavros Papamarinopoulos gave examples of such multi-ringed concentric morphology resulting from asteroid impacts. Not only does their suggestion provide a rational explanation for the shape of the canals but would also explain the apparent over-engineering of those waterways.

At the same conference, the late Ulf Richter presented his idea [629.451], which included the suggestion that the concentric rings around the centre of the Atlantis capital had a natural origin. Richter has proposed that the Atlantis rings were the result of the erosion of an elevated salt dome that had exposed alternating rings of hard and soft rock that could be adapted to provide the waterways described by Plato.

Georgeos Diaz-Montexano has suggested that the ancient city under modern Jaen in Andalusia, Spain had a concentric layout similar to Plato’s description of Atlantis. In August 2016 archaeologists from the University of Tübingen revealed the discovery(i) of a Copper Age, Bell Beaker People site 50km east of Valencina near Seville, where the complex included a series of concentric earthwork circles.

Gilgal refai'm

A very impressive example of man-made concentric stone circles, known in Arabic as Rujm el-Hiri and in Hebrew as Gilgal Refaim(a), is to be found on the Golan Heights, now part of Israeli occupied Syria. It consists of four concentric walls with an outer diameter of 160metres. It has been dated to 3000-2700 BC and is reputed to have been built by giants! Mercifully, nobody has claimed any connection with Atlantis. That is until 2018 when Ryan Pitterson made just such a claim in his book, Judgement of the Nephilim[1620].

Jim Allen in his latest book, Atlantis and the Persian Empire[877], devotes a well-illustrated chapter to a discussion of a number of ‘circular cities’ that existed in ancient Persia and which some commentators claim were the inspiration for Plato’s description of the city of Atlantis. These include the old city of Firuzabad which was divided into 20 sectors by radial spokes as well as Ecbatana and Susa, both noted by Herodotus to have had concentric walls. Understandably, Allen, who promotes the idea of Atlantis in the Andes, has pointed out that many sites on the Altiplano have hilltops surrounded by concentric walls. However, as he seems to realise that to definitively link any of these locations with Plato’s Atlantis a large dollop of speculation was required.

Rodney Castleden compared the layout of Syracuse in Sicily with Plato’s Atlantis noting that the main city “had seen a revolution in its defensive works, with the building of unparalleled lengths of circuit walls punctuated by numerous bastions and towers, displaying the city-state’s power and wealth. The three major districts of the city, Ortygia, Achradina and Tycha, were surrounded by three separate circuit walls; Ortygia itself had three concentric walls, a double wall around the edge and an inner citadel”.[225.179]

Dale Drinnon has an interesting article(d) on the ‘rondels’ of the central Danubian region, which number about 200. Some of these Neolithic features have a lot in common with Plato’s description of the port city of Atlantis. The ubiquity of circular archaeological structures at that time is now quite clear, but they do not demonstrate any relationship with Atlantis.

The late Marcello Cosci based his Atlantis location on his interpretation aerial images of circular features on Sherbro Island, but as far as I can ascertain this idea has gained little traction.

One of the most remarkable natural examples of concentric features is to be found in modern Mauritania and is known as the Richat Structure or Guelb er Richat. It is such a striking example that it is not surprising that some researchers have tried to link it with Atlantis. Robert deMelo and Jose D.C. Hernandez(o) are two advocates along with George S. Alexander & Natalis Rosen who were struck by the similarity of the Richat feature with Plato’s description and decided to investigate on the ground. Instability in the region prevented this until late 2008 when they visited the site, gathering material for a movie. The film was then finalised and published on their then newly established website in 2010(l), where the one hour video in support of their thesis can be freely downloaded(m).

In 2008, George Sarantitis put forward the idea that the Richat Structure was the location of Atlantis, supporting his contention with an intensive reappraisal of the translation of Plato’s text(n). He developed this further in his Greek language 2010 book, The Apocalypse of a Myth[1470] with an English translation currently in preparation.

However, Ulf Richter has pointed out that Richat is too wide (35 km), too elevated (400metres) and too far from the sea (500 km) to be seriously considered as the location of Atlantis.

A dissertation by Oliver D.Smith has suggested(e) the ancient site of Sesklo in Greece as the location of Atlantis, citing its circularity as an important reason for the identification. However, there are no concentric walls, the site is too small and most importantly, it’s not submerged. Smith later decided that the Atlantis story was a fabrication!(p)

Brad Yoon has claimed that concentric circles are proof of the existence of Atlantis, an idea totally rejected by Jason Colavito(j).

In March 2015, the UK’s MailOnline published a generously illustrated article(g) concerning a number of sites with unexplained concentric circles in China’s Gobi Desert. The article also notes some Gobi Desertsuperficial similarities with Stonehenge. I will not be surprised if a member of the lunatic fringe concocts an Atlantis theory based on these images. (see right)

>Paolo Marini has written Atlantide:Nel cerchio di Stonehenge la chiave dell’enigma (Atlantis: The Circle is the Key to the enigma of Stonehenge) [0713]. The subtitle refers to his contention that the concentric circles of Atlantis are reflected in the layout of Stonehenge!<

In 2011 Shoji Yoshinori offered the suggestion that Stonehenge was a 1/24th scale model of Atlantis(f). He includes a fascinating image in the pdf.

This obsession with concentricity has now extended to the interpretation of ancient Scandinavian armoury in particular items such as the Herzsprung Shield(c).

For my part, I wish to question Plato’s description of the layout of Atlantis’ capital city with its vast and perfectly engineered concentric alternating bands of land and sea. This is highly improbable as the layout of cities is invariably determined by the natural topography of the land available to it(h). Plato is describing a city designed by and for a god and his wife and as such his audience would expect it to be perfect and Plato did not let them down. I am therefore suggesting that those passages have been concocted within the parameters of ‘artistic licence’ and should be treated as part of the mythological strand in the narrative, in the same way, that we view the ‘reality’ of Clieto’s five sets of male twins or even the physical existence of Poseidon himself.

Furthermore, Plato was a follower of Pythagoras, who taught that nothing exists without a centre, around which it revolves(k). A concept which may have inspired him to include it in his description of Poseidon’s Atlantis.

Phaëton in Greek mythology was the son of Helios the Greek sun god. Phaëton was also the name given to a comet that impacted or had a close encounter with the Earth in the 13th century BC. The Egyptians knew this comet as Sekhmet. Ancient inscriptions record that some of the consequences of this dramatic encounter were the drying up of the Nile and the desertification of Libya.

Michel-Alain Combes has noted(j)  that Phaëton has also been associated “with Anat in Syria, the star of Baal in Canaan (Palestine and Phenicia), Absinthe, The star of the Apocalypse) among the Hebrews, Surt in the countries of the north.”> He also suggests that the legends of Typhon (Hesiod) and Phaeton (Ovid), although usually thought to refer to separate events, are just different versions of the same encounter with a comet in the late 13th century BC.<

A 2012 paper by Peter James and M.A, van der Sluijs entitled ”Silver’: A Hurrian Phaethon’ (l) concluded that “there is an attractive pattern of correspondences between the well-known Greek myth of Phaethon and the Hurrian myth of Silver.” Silver was a character in Hurrian mythology, also know as Ushu.

Interestingly, Plato records in Timaeus how Phaëton caused immense devastation but does not link it directly with the destruction of Atlantis but the context implies an event that was in the distant past, considerably earlier than Solon. Some ancient authorities, such as Eusebius and Isidore of Seville, have associated Phaëton with the time of Moses.

The poet Goethe considered the story of Phaëton to have had a real astronomical origin.

Franz Xavier Kugler was a Jesuit priest who spent over thirty years studying ancient astronomical texts written in cuneiform. In 1927, he published a paper in which he concluded that an asteroidal impact in the Mediterranean inspired the story of Phaëton.

More recently, Bob Kobres has written a number of articles on the subject of Phaëton having a cometary origin(k).  Some of these papers can be found on the Internet(a). Kobres dates this Phaëton event to around 1200 BC.

Stavros Papamarinopoulos from the University of Patras in Greece presented a paper to the 2005 Atlantis Conference held on Melos in which he linked Plato’s Phaëton with an encounter between the earth and cometary fragments around 1200 BC.

Emilio Spedicato has opted for 1447 BC as the likely date of the Phaëton explosion. He describes this as a super-Tunguska event, which exploded over southern Denmark(m). He further contends that the after-effects assisted the Israelite Exodus from Egypt.

Spedicato’s identification is comparable with Jürgen Spanuth’s idea that Phaëton was a fragment of Halley’s Comet. Two other followers of Spanuth, Günter Bischoff and Walter Stender have written extensive papers, in German, on a meteorite impact with Northern Europe around 1220 BC, which they identify as Phaëton(c). The same interpretation has been applied specifically to Lake Chiemgau in S.E. Bavaria and is expanded on in papers by Barbara Rappenglück among many others.(d)(f)

Holger Kalweit, who also follows Spanuth in identifying Heligoland as a remnant of Atlantis, claims it was destroyed in 1222 BC by Phaëton.

Clube & Napier [0290]  have proposed a slightly later date of  1369 BC for the encounter with Phaëton.

Dale Drinnon has argued(g) against any connection between Phaeton and the destruction of Atlantis saying “There are two different kinds of catastrophes being described and distinguished from one another and the Phaethon event is categorically differentiated from the Destruction of Atlantis in the Atlantis dialogues of Plato. There is no good reason to equate the two and certainly no textual justification for doing so.”

Allan & Delair refer to the central cause of the catastrophe described in their book[014] as Phaëton, which they claim was cosmic ejecta from a supernova in the Vela constellation.

Amanda Laoupi offers an extensive article on the history of the Phaëton myth and its interpretation in both ancient and modern times.

Phaëton was also the name given by Johann Gottlieb Radlof (1775-1829) to a planet which he believed disintegrated after a collision with a comet, within human memory, resulting in the asteroid belt.

Island, Peninsula or Continent?

Island, Peninsula or ContinentAdvocates of a continental rather than island identification for Atlantis have to contend with the fact that Plato never referred to Atlantis as a continent instead he used the Greek words for ‘island’, namely ‘nesos’ and ‘neson’. Their line of argument is that these words in addition to ‘island’ or ‘islands’ can also mean “islands of an archipelago” or “peninsula”. Furthermore, it is claimed that the ancient Greeks had no precise word for ‘peninsula’.

Gilles le Noan[912], quoted by Papamarinopoulos[629.558], has offered evidence that there was no differentiation in Greek between ‘island’ and ‘peninsula’ until the time of Herodotus in the 5th century BC. In conversation with Mark Adams[1070.198] he explains that in the sixth century BC, when Solon lived, nesos had five geographic meanings. “One, an island as we know it. Two, a promontory. Three, a peninsula. Four, a coast. Five, a land within a continent, surrounded by lakes, rivers or springs.”

>Elena P. Mitropetrou a Greek archaeologist at the University of Patras, delivered two papers to the 2008 Atlantis Conference in Athens [750]. She also pointed out that in the 6th century BC, the Greek word nesos was employed to describe an island, but also, a peninsula or a promontory. Mitropetrou herself considers the Iberian peninsula to be the ‘island of Atlantis.’<

Robert Bittlestone, in his Odysseus Unbound [1402.143] also notes that “nesos usually means an island whereas cheronesos means a peninsula, but Homer could not have used cheronesos when referring to the peninsula of Argostoli for two very good reasons. First, it cannot be fitted into the metre of the epic verse and second, the word hadn’t yet been invented: it doesn’t occur in Greek literature until the 5th century BC.”

Another researcher, Roger Coghill, echoed the views of many when he wrote on an old webpage that “To the Greeks peninsulae were the same as islands, so the Peloponnesian peninsula was “the island of Pelops” and the Chersonnese was to them “the island of Cherson”. Similarly in describing a place found after escaping the Pillars of Hercules, Plato quite normally describes the Lusitanian coast (modern Portugal) as an “island”, reached, he clearly says, after passing Cadiz”.

Johann Saltzman claimed that ‘nesos’ did not mean ‘island’ or ‘peninsula’ but ‘land close to water’. However, I would be happier sticking to the respected Liddell & Scott’s interpretation of island or peninsula. If Saltzman is correct, what word did the Greeks use for island?

The Modern Greek word for peninsula is ‘chersonesos’ which is derived from ‘khersos’ (dry) and ‘nesos’ (island) and can be seen as a reasonable description of a peninsula. It is worth noting that the etymology of the English word ‘peninsula’ is from the Latin ’paene’ (almost) and ’insula’ (an island).

Jonas Bergman maintains that the Greek concept of ‘island’ is one of detachment or isolation. He also points out that the original Egyptian word for ‘island’ can also mean lowland or coastland because the Egyptians had a different conception of ’island’ to either the ancient Greeks or us. Some commentators have claimed that the Egyptians of Solon’s time described any foreign land as an island.

Eberhard Zangger offers another correction of the Atlantis mystery: If one compares the land-sea distribution in Egypt and in the Aegean Sea, it becomes obvious why the Egyptians used at that time the expression “from the islands”. While today the word “island” has a clear meaning, this was not the case in the late Bronze Age. For the Egyptians more or less all strangers came from the islands. As there had been practically no islands in Egypt, the ancient Egyptian language did not have any special character for it. The hieroglyphic used for “island” was also meaning “sandy beach” or “coast” and was generally used for “foreign countries” or “regions on the other side of the Nile”.

A contributor to the Skeptic’s Dictionary(b) has added “I remind you that the Greek definition of “island” paralleled that of “continent.” To the Greeks, Europe was a continent. West Africa was an island, especially since it was cut off from the rest of what we now call “Africa” by a river that ran south from the Atlas mountains and then west to what is now the western Sahara. This now dry river was explored by Byron Khun de Prorok in the 1920s.”

Reginald Fessenden wrote: “One Greek term must be mentioned because it has given rise to much confusion. The word ‘Nesos’ is still translated as meaning ‘island’ but it does not mean this at all, except perhaps in late Greek. The Peloponnesus is a peninsula. Arabia was called a “nesos” and so was Mesopotamia”. This ambiguity in the written Greek and Egyptian of that period was highlighted at the 2005 Atlantis Conference by Stavros Papamarinopoulos.

Werner Wickboldt pointed out at the same conference that Adolph Schulten in the 1920’s referred to a number of classical writers who used the term ‘nesos’ in connection with the Nile, Tiber, Indus and Tartessos, all of which possessed deltas with extensive networks of islands.

To confuse matters even further, there have been a number of theories based on the idea that the ‘island’ of Atlantis was in fact land surrounded by rivers rather than the sea. These include Mesopotamia in Argentina proposed by Doug Fisher, the Island of Meroë in Sudan suggested by Thérêse Ghembaza and a large piece of land bound by the Mississippi, Ohio, and Potomac rivers offered by Henriette Mertz. However, none of these locations matches Plato’s description of Atlantis as a maritime trading nation with a naval fleet of 1200 ships, nor do any of them explain how they controlled the Mediterranean as far as Egypt and Tyrrhenia.

The waters around Plato’s island are indeed muddy!
