Viracocha
Sumerians *
Sumeria was one of the earliest civilisations emerging between the 6th and 5th millennia BC and was situated in what is now central Iraq.
It was unknown in Europe until the middle of the 19th century. With the discovery and the decipherment of the Sumerian cuneiform tablets the sophistication of their culture prompted the idea that Sumer had been ‘the cradle of civilisation.’ Subsequent discoveries, such as those in the Indus Valley and more recently Göbekli Tepe have now somewhat diluted that idea.
Nevertheless, there is an acceptance that the Sumerians were very advanced in the field of mathematics and astronomy. The late Ernest McClain, a professor of music, was convinced that music theory could be traced back to the Sumerians as early as 3000 BC.
The origin of the Sumerians is still something of a mystery as is their language which seems to be an ‘isolate’, unrelated to any known language group(q). The Flem-Aths in an Atlantis Rising article (Issue 95) and Atlantis Beneath the Ice [981.70] claimed a cultural and genetic linkage between the Sumerians and the Haida of northwest America. The Flem-Aths also noted [062.54] that some have linked the languages of the two peoples!
Ronnie Gallagher has suggested that migrants from the Caucasus had provided the impetus that led to the development of the Sumerian civilisation. Gallagher’s theory is supported by Jerald Jack Starr on his Sumerian Shakespeare website, who emphatically attributes a Caucasian origin to the Sumerians(l).
Emilio Spedicato has controversially suggested that the Sumerians came from the Tibetan region!(m) Equally provocative were the views of Catherine Acholonu-Olumba, who as the author of Eden in Sumer on the Niger [1833], claimed that her book, “provides multidisciplinary evidence of the actual geographical location in West Africa of the Garden of Eden, Atlantis and the original homeland of the Sumerian people before their migration to the “Middle East”. By translating hitherto unknown pre-cuneiform inscriptions of the Sumerians, Catherine Acholonu and Sidney Davis have uncovered thousands of years of Africa’s lost pre-history and evidences of the West African origins of the earliest Pharaohs and Kings of Egypt and Sumer such as Menes and Sargon the Great.”(p)
Sumeria has now been proposed as a possible source of the Atlantis story. Dr Ashok Malhotra, a professor of Engineering, has suggested(a) that that ‘the likelihood of the Atlantis stories being of Sumerian origin is strengthened by the fact that the submergence of ancient cities was a strong part of the Sumerian mythology. It dominates their historical tradition. The destruction of the ancient city as a result of sin was also part of their beliefs.’ Malhotra then proposes that these Sumerian stories reflected actual flooding events in the Indus Valley region that were brought first to Sumeria and then were later transferred to Egypt and from thence via Solon to Plato to us.
George Michanowsky went much further and claimed that the Sumerians had known Atlantis under the name of NI-DUK-KI, known today as Dilmun[282.66]. The renowned Henry Rawlinson interpreted this name to mean ‘blessed hill’ or ‘blessed isle’. While Michanowsky’s suggestion is highly speculative, if correct, it would be the earliest known reference to Atlantis.
The Sumerian king list(e) from Larsa records eight kings (some versions note ten) before the Deluge, which may have been reflected, in a distorted fashion, in the ten patriarchs of Genesis and/or the ten kings of Atlantis! Another suggested link is with the eight generations between Adam and Noah recorded in Genesis chapter 5.
John Sassoon would seem to support Malhotra’s thesis in his book[566], which proposes a Sumerian origin for the Jews with possible earlier links with the Indus Valley. He is not concerned with Atlantis, just the ancestry of the Jewish people of whom Abraham was born in Sumeria around 2000-1800 BC. Sassoon’s views offer a possible transmission route for Eastern traditions and myths to have reached Egypt and subsequently through Solon to Athens.
More recently, Dr Willem McLoud, a South African researcher, commented that “we have good reason to think that Atlantis was not located beyond the pillars of Heracles in the Atlantic Ocean, as is so often propagated, but that it was actually none other than the ancient land of Sumer itself.” Mcloud is primarily concerned with the Sumerians and Akkadians, which he will expand on in a forthcoming book(n).
In 2001, a book by Radek Brychta was published in the Czech Republic in which he also advocates a Sumerian connection. He identifies Atlantis with the legendary Dilmun of Sumerian legend and locates it on the Indus civilisation island of Dholavira. Excerpts from this fascinating book are available on the Internet and are worth a read.
However, the most extreme claims came from Zechariah Sitchin who proposed that the Sumerians had been ‘influenced’ by ancient astronauts from the planet Nibiru, which information is to be found in their cuneiform tablets if Sitchin’s translation is to be believed. Similar daft ideas(g) have been put forward by Hermann Burgard[1316] but so far have only been foisted on a German-reading public.
As if that was not bad enough, we now (Oct 2016) have the Iraqi Transport Minister claiming, among other matters, that the Sumerians launched spaceships 8,000 years ago(h)!
The Sumerian texts also crop up in the wild theories of Dieter Bremer[1022] and Jakob Vorberger, who claim that Atlantis was a space station(I)!
Jim Allen, the leading advocate of ‘Atlantis in the Andes’ has also claimed(b) a Sumerian connection with South America citing Ruth & Alpheus Hyatt Verrill, who include in their book[838.293] three pages of Sumerian words compared with the language of ancient Peru as well as other cultural aspects there. They also believed that Sargon (2369-2314 BC) was known in Peru as the deity Viracocha! Their fanciful idea stems from an account of Sargon sailing to the West and spending three years there! Zhirov supported this claim[458.23] describing it as ”a seemingly semi-fantastic theory”. My reason for considering this claim to be nonsensical, is simply that Sargon was continually engaged in expanding his empire and constantly dealing with rebellions in the various city-states that he ruled over. The idea that he took three years out to visit America, 14,000 km away, is in no way credible.
Nevertheless, the idea of Sargon in South America persists with James Bailey repeating it in Sailing to Paradise[0150.66] and more recently by the Afrocentrist, Clyde Winters in an article on the Ancient Origins website(f) in which he quotes Bailey and the Verrills as supporting Lake Titicaca as the Lake Manu of Sumerian tradition. A further article(j) on the same website begins with the forceful claim that “it is becoming increasingly clear that the Sumerians had established a colony in South America called Kuga-Ki.” The paper is based on a series of questionable artefacts, the Fuente Magna Bowl, the Crespi Collection and the Pokoyia monument!
The Fuente Magna Bowl is frequently offered as evidence of a pre-Columbian link with the Sumerians in America(c), although its provenance is unclear and there are the inevitable suggestions of a hoax. A sceptical view of the ‘Bowl’ by Carl Feagans(k) is available.
Michel Leygues has published two papers in which he offers evidence that the Sumerian and Akkadian languages can be identified in the languages of many of the native America peoples including the Hopi, Navajo and Incas(s)(t). Leygues also “presents the hypothesis that a kinship exists between Yamato Kotoba ideographic values, and Sumerian and Akkadian values. This despite a great geographical distance between Mesopotamia and Japan, and at different historical periods of language use. “(u)
Other commentators have suggested that the Sumerians reached Spain. Dr Paul Haupt (1858-1926}, an early Assyriologist proposed that the ‘two rivers’ in the story of Utnapishtim, a Noachian equivalent, were the Guadalquivir and Guadiana of Andalusia(r). Mario Mas Fenollar is a modern advocate for Sumerians in Spain.
The very existence of Sumerians has recently been attacked in an appendix to The Three Ages of Atlantis[972] by Marin, Minella & Schievenin. They maintain that the Sumerian ‘language’ “could be an artificial construct created by Akkadian priests” to be used for liturgical purposes. These ideas were first expressed at the end of the 19th century by the respected Orientalist, Joseph Halévy. Andi Zeneli has expressed comparable ideas(d) regarding the Sumerian language.
Uwe Topper’s son Ilya has also put forward the idea that the Sumerians did not exist(o). His paper is a critique, originally in Spanish, of Gunnar Heinsohn’s Die Sumerer gab es nicht.

America *
America as the home of Atlantis took off as an idea shortly after its discovery (or perhaps more correctly, rediscovery) by Columbus. Initially, reports sent back to Europe designated America as ‘Paradise’
until its identification as Atlantis quickly took hold. John Dee in the time of Elizabeth I was convinced that the newly discovered Americas were in fact, Atlantis, an idea endorsed by Francis Bacon. The first time that America was so named on a map was on the 1507(c) Waldseemüller map, sometimes referred to as “America’s birth certificate.” A rare copy of this map was recently found in Germany(e).
Nevertheless, from the early 1600’s dissenting voices were raised, such as those of José de Acosta, and Michel de Montaigne.
As late as 1700, a map of the world by Edward Wells was published in Oxford that highlights the paucity of information regarding the Americas at that time. However, in this instance the accompanying text notes that “this continent with the adjoining islands is generally supposed to have been anciently unknown though there are not wanting some, who will have even the continent itself to be no other than the Insula Atlantis of the ancients.”
For over five centuries a variety of commentators have associated Atlantis with America and many of its ancient cultures together with a range of location theories that stretch from Maine through the Caribbean and Central America to Argentina.
Although most proponents of an American Atlantis, particularly following the continent’s discovery, did not specify a location but were happy to consider the Americas in their entirety as Plato’s lost land. In 2019, Reinoud de Jonge published a paper declaring that from 2500-1200 BC America had been an Egyptian colony. He expanded on this in 2912(l), when he claimed that the American colonies, North and South had supplied the copper and tin for the Bronze Age of the Mediterranean. For good measure, he threw in a wildly speculative translation of the Phaistos Disk to support these contentions.
Over time attention was more focused on Mesoamerica and the northern region of South America, where the impressive remains of the Maya and Incas led many to consider them to be Atlantean.
North America received minimal attention until the 19th century when an 1873 newspaper report(i) claimed that there was support from unnamed scientists for locating remnants of Atlantis in the Adirondacks and some of the mountains of Maine! More recently Dennis Brooks has advocated Tampa Bay, Florida, while John Saxer supports Tarpon Springs, also in Florida as Atlantean. To confuse matters further, Mary Sutherland locates Atlantis in the Appalachian Mountains of Kentucky and for good measure suggests that King Solomon’s mines are to be found in the same region!
For example, the discovery of the remains of the remarkable cultures of Mesoamerica generated speculation on the possibility of an Atlantean connection there. This view gained further support with the publication of Ignatius Donnelly’s groundbreaking work on Atlantis.
Some have seen an Atlantic location for Atlantis as a conduit between the culture of ancient Egypt and that of Meso-America(d).
Half a century ago Nicolai Zhirov claimed that Plato had knowledge of America [458.22] indicated by his statement that Atlantis was in a sea with a continent encompassing it. He thought that this was the earliest record of a continent beyond the Atlantic.
However, Plato also said that Atlantis was surrounded ‘on all sides’ by this continent, which is not compatible with the Azores, advocated by Zhirov as the location of Plato’s sunken island. In an effort to strengthen this claim Zhirov also claims that there is evidence that King Sargon of Akkad travelled to America in the middle of the third millennium BC, an idea that has gained little traction.
The idea of Sumerians in America was promoted by A.H. Verrill and his wife Ruth, who claimed [838] that King Sargon travelled to Peru, where he was known as Viracocha. The Verrills support their contention with a range of cultural, linguistic and architectural similarities between the Sumerians and the Peruvians.
More recently, Andrew Collins has promoted the idea of Atlantis in the Caribbean, specifically Cuba. Followers of Edgar Cayce are still expecting the Bahamas to yield evidence of Plato’s island. Gene Matlock supports the idea of a Mexican location with an Indian connection, while Duane McCullough opts for Guatemala. Ivar Zapp and George Erikson have also chosen Central America for investigation. Further south Jim Allen has argued strongly for Atlantis having been located on the Altiplano of Bolivia. A website entitled American Atlantis Research from Edward Alexander , now offline, was rather weak on content and irritatingly referred to the ‘Andies’.
Although much of what has been written about an American location for Atlantis is the result of serious research, it all falls far short of convincing me that the Atlantis of which Plato wrote is to be found there. No evidence has been produced to even hint that any American culture had control of the Mediterranean as far Tyrrhenia in the north and Libya in the south. No remains or carvings of triremes or chariots have been found in the Americas. How could an ancient civilisation from America launch an attack across the Atlantic and at the furthest end of the Mediterranean 9,000 or even 900 years before Solon? An even more important question is, why would they bother? There is no evidence of either motive, means or opportunity for an attack from that direction.
A number of Plato’s descriptions of Atlantis would seem to rule out America as its location.
(a) As mentioned above, the ‘opposite continent’ referred to by Plato (Timaeus 25a) is described as encompassing the sea in which Atlantis lay. America cannot be described as enclosing the Atlantic. Around 550 AD, Procopius noted that when viewed from the southern side of the Strait of Gibraltar “the whole continent opposite this was named Europe”(m) (not America)!
(b) The Greeks only knew of three continents, Europe, Asia and Libya. Armin Wolf, the German historian, when writing about Scheria relates(f) that “Even today, when people from Sicily go to Calabria (southern Italy) they say they are going to the “continente.” I suggest that Plato used the term in a similar fashion and was quite possibly referring to that same part of Italy which later became known as ‘Magna Graecia’. Robert Fox in The Inner Sea[1168.141] confirms that this long-standing usage of ‘continent’ refers to Italy.
(c) Herodotus described Sardinia as “the biggest island in the world” (Hist.6.2). In fact Sicily is marginally larger but as islands were measured in those days (Felice Vinci) [019] by the length of their coastal perimeter Herodotus was correct. Consequently, it can be argued that since Cuba and Hispaniola are much more extensive than Sardinia, the Greeks had no knowledge of the Caribbean.
(d) Plato makes frequent references to horses in Atlantis. The city itself had a track for horseracing (Critias 117c). The Atlanteans had thousands of chariots (Critias 119a). The Atlanteans even had horse baths (Critias 117b). All these references make no sense if Plato was describing an American Atlantis as there were no horses there for over 12,000 years, when they died out, until brought back by the Spaniards millennia later. Furthermore, it makes even less sense if you subscribe to the early date (9600 BC) for Atlantis as it is thousands of years before we have any evidence for the domestication of the horse, anywhere.
A recent study of worldwide DNA patterns suggests that “no more than 70 people inhabited North America 14,000 years ago.”(b) But a more important claim has been offered by Professors Jennifer Raff and Deborah Bolnick who have co-authored a paper offering evidence(j) that the genetic data only supports a migration from Siberia to America. This certainly runs counter to any suggestion of transatlantic migration from Europe.In 1900,
Peter de Roo put forward the idea that the ancient Greeks had knowledge of America, despite the fact that Herodotus clearly said that only three continents were known to them [Histories 4.42]. A 2013 book, L’America dimenticata [1060], by Italian physicist and philologist Lucio Russo, also claims that the ancient Greeks had knowledge of America and it was gradually forgotten because of mistakes made by Ptolemy including a 15-degree error for the latitude of the Canaries(g).
However, the idea that the Greeks had an awareness of America persists, with some claiming that they had colonies in Canada. Among these are Lucio Russo, Ioannis Liritzis(n) and Minas Tsikritsis(p). Manolis Koutlis has gone one further and claims that not only were there Greek Colonies in Canada but that Atlantis had been situated in the Gulf of St. Lawrence(o).
The late Professor Antonis Kontaratos placed the capital of Atlantis at Poverty Point in Louisiana or it at least inspired some of Plato’s description since “there is also solid evidence that the Greeks were travelling to America in prehistoric times too and could have witnessed firsthand the impressive earthworks at Poverty Point, information which could have reached Plato independently as a fading legend [0750].” Kontaratos cited Plutarch to support his contention of Greek transatlantic travel in prehistory.
I note that there is a suspiciously disproportionate number of Greeks supporting the idea of pre-Columbian Hellenic visitors to America!
While there is extensive debate regarding the Americas being visited by ancient Greeks (Minoans), Phoenicians and even Sumerians, there seems little doubt that America had been visited by various other peoples prior to Columbus such as Welsh, Vikings or Irish. The case for the latter is strengthened by a 500-year-old report(h) of a long-established Irish colony in North America called Duhare.
America as Atlantis and the source of freemasonry knowledge was recently repackaged in a brief article on the Odyssey website(k) quoting Manly P. Hall who in turn cited Plato and Sir Francis Bacon. It then proceeds to speculate on what lessons the story of this original American Atlantis offers the America of today!

Incas
The Incas or at least their ancestors are claimed by Jim Allen to have ruled Atlantis, which he insists exited on the Altiplano of the Andes in Bolivia. However, the idea of a connection between Atlantis and the cultures of Central and South America is not new, having been first mooted by Pedro Samiento de Gamboa in 16th century. Supporters of the theory today cite the extremely controversial Oera Linda Book which states that one of the Frisian naval commanders named Inka reached America after the destruction of Atlantis. With this tenuous etymological link they conclude that he was the founder of the Inca civilisation, ignoring the fact that the earliest evidence for the Inca tribe dates to around 1200AD while the Oera Linda Book puts the destruction of Atlantis circa 2200BC, leaving an unexplained gap of nearly 3500 years. A Frisian–Inca connection is also proposed on the Stepping Stones website(a) which for good measure endeavours to link them with the Shang Chinese, the Magyars and, of course, the Atlanteans(b).
The great tragedy of the Inca culture is that they left no written records with the exception of the knotted strings known as quipu (khipu)(d). Gary Urton is a Professor of pre-Columbian Studies and has a website dedicated to the study of quipu(e). In April 2017, Sabine Hyland published a paper on some late 18th century khipus made of animal hair, which according to local Peruvian villagers contained an account of an uprising against the Spaniards(g)(i).
But now, Urton and Alejandro Chu, of the Universidad Nacional Mayor de San Marcos in Lima have studied a collection of khipus at the Inkawasi site have concluded that the khipus in question probably recorded taxes levied on local crops(j).
Leaving aside any consideration of an Atlantean link with the Inca people, there is no doubt that that the Incas possessed remarkable construction capabilities. It has been estimated that they constructed nearly 25,000 miles of roadway in a period of around 100 years(f)! This network, known as Qhapaq Ñan, extends over six countries and is now a Unesco World Heritage Site, the largest on the planet. Unfortunately it has been allowed to deteriorate. Efforts are being made to redress this unfortunate situation(h).
The megalithic masonry to be found in Cusco, their ancient capital, further highlights their outstanding construction abilities. A recent well-illustrated book by Brien Foerster, Lost Ancient Technology of Peru and Bolivia[923] examines a range of Incan sites and their often enigmatic monuments. This is a valuable addition to the literature on the subject.
In 2007 the Peruvian engineer and writer, Jesus Americo Huari Roman (1950-), wrote a book (for private circulation) entitled La Atlantida y el Imperio de los Incas (Atlantis and the Empire of the Incas), in which he also argues that then Incas were descendants of the Atlanteans. He has video clips on YouTube supporting his theory(a), unfortunately, with Spanish dialogue only.

Cuzco
Cuzco is a provincial capital of modern Peru, which in the 11th century was the capital of the Inca Empire. One remarkable sight in the city is the 12-angle stone in the wall on Hatun Rumiyoc Street, which has now been outdone by a 13-angle stone, recently identified, which is built into an irrigation system at the Inkawasi archaeological site, located in Huancavelica region’s Huaytará district(c). The astonishing mortarless Inca masonry in the town has to be seen to be believed.
A few years ago Davide Andrea published his theory on how the Incas fitted those multi-angled stones(d). April Holloway has touched on the suggestion that the Incas or their predecessors had discovered how to soften stone(g). An extensive four-part article elsewhere(h) focuses on the Sri Lankan site of Sigiriya. where what appears to be numerous examples of softened stone can be seen. However, the author concluded that what was on display were features that had been cast in situ and that the same method had been employed when building the pyramids and creating the huge monoliths of Baalbek! It is worth noting that Andrea concluded that “we’re still unsure of how the Incas fit the stones so perfectly”.
The city of Cuzco contained The Corichancha, (Place of Gold), which the Incas dedicated to Viracocha and which astounded the Conquistadors in the 1530s when confronted with its opulence(b). It was covered inside and out with over 700 sheets of gold and silver. The nearby Garden of the Sun contained golden animals, birds and plants. Pipes, aqueducts and basins were also made of gold. The complex was fed by natural hot and cold springs. Apart from all this ostentatious wealth, some writers have drawn further parallels between Plato’s Atlantis, Homer’s Phaeacia and the Cuzco of the Incas. Although nobody, so far, has suggested that Cuzco had been the location of Atlantis it has been mooted that it may have been constructed as a reminder of the glory of a previous homeland. Donnelly considered Peru to be an Atlantean colony. Local people are clearly not unaware of the suggestion that Cuzco has been associated with Plato’s lost city and so you will find the Atlantis Hotel within a few blocks of the main square.
>Just 2 km north of Cuzco’s main square lies the remarkable fortress/temple of Sacsayhuaman, which is the largest structure ever built by the Inca. The irregular shaped stones used in its construction fit together like a jigsaw puzzle without the use of any mortar.<
Frank Joseph states[102] that north-west of Cuzco there is a sacred mountain whose summit and a village on its southern slope are known as Atalaia. Pre-Inca remains are also to be found in the vicinity of Cuzco, an ancient sun-worshipping city, which was recently discovered to have the highest ultra-violet levels on our planet. For centuries rumours have persisted(a) that a series of tunnels existed under Cuzco. In 2000, a 2 km tunnel was discovered beneath the city by the Spanish archaeologist, Anselm Pi Rambla(f).
Yale University in the United States, and the Universidad Nacional de San Antonio Abad del Cuzco (UNSAAC) in Peru, announced the establishment of an International Center for the Study of Machu Picchu and Inca Culture, in Cuzco. The Centre opened in 2011(a) following the return of hundreds of items looted by Hiram Bingham.
Brian Foerster is convinced that pre-Incan advanced technology was used in the earliest construction of Cusco, an idea that he expands on in a short YouTube video(e).
