Ancient Seafaring is a controversial subject owing principally to a dearth of physical evidence. The earliest known boat is the Pesse
Canoe (see right) which was discovered in The Netherlands and thought to be around 10,000 years old. The second oldest boat was also a canoe, found in Malawi and dated to about 8,000 years ago(g). Wikipedia lists all the surviving boats, which shows that until the third millennium BC all that have been found are canoes.
Seafaring and Atlantis are inextricably linked. In Critias 117d Plato anachronistically refers to the shipyards of Atlantis being full of triremes, which were not developed until the 7th century BC, long after the demise of Atlantis. However, the term ‘trireme’ was probably employed by Plato to make his narrative more relevant to his audience. He credits the Atlantean navy with 1200 ships, which for me seems like borrowing and rounding the numbers of either the Achaean fleet of 1186 vessels in Homer’s Iliad or that of the 1207 ships of the later Persian invaders. That ships were used in the war with Athens can be inferred from the fact that Atlantis, or at least its capital, was situated on an island.
Professor Seán McGrail (1928-2021) wrote in his monumental work, Boats of the World “There is no direct evidence for water transport until the Mesolithic even in the most favoured regions, and it is not until the Bronze Age that vessels other than logboats are known” [1949.10]. For those that adhere to a 10th millennium BC date for the Atlantean War with Athens, this lack of naval evidence to support such an early date undermines the idea. An invasion fleet of canoes travelling from beyond the Pillars of Herakles to attack Athens seems rather unlikely!
Apart from the flimsy Solar Boats of the Egyptians, such as the Khufu Boat (see left), the first seagoing vessel listed by Wikipedia does not appear until around 1500 BC.
Seldom referred to, but perhaps even more interesting is to be found earlier in Critias 113e which describes the mythological beginnings of Atlantis and reads “for at that time neither ships nor sailing were as yet in existence”. However, we are given little information to bridge the time up to its development as a major trading entity. It is reasonable to assume a gap of several thousand years.
Recent studies(a) have suggested that primitive seafaring took place in the Mediterranean thousands of years earlier than originally thought and may even have been engaged in by Homo Erectus and Neanderthals in the form of island hopping and coastal-hugging, the latter continuing into historical times.
Plato describes an advanced maritime trading nation with a powerful naval capacity. How much was part of the original story brought from Egypt by Solon or whether it was in any way embellished by Plato is unclear. The earliest known trading empire is that of the Minoans which began in the 3rd millennium BC and has led to many identifying them with the Atlanteans. However, there are very many other details in Plato’s narrative that seriously conflict with this hypothesis.
The limitations of ancient seafaring raise many questions regarding the navigation supports available to these early sailors(b). Initially, sailing, probably for fishing, would have been confined to daytime travel and keeping within the sight of land. With the development of maritime trade, the demand for improved navigation methods also grew.
In time sailors acquired a familiarity with the night sky that enabled them to use the stars as navigational aids, given clear skies. Gradually, as nighttime travel became more common, the use of beacons and later lighthouses also expanded. The lighthouse at Pharos near Alexandria came to be counted as one of the wonders of the Old World. Similarly, it is thought that the Colossus at Rhodes performed a similar function.
Different navigation skills have been identified in different parts of the world. In the Pacific, the navigational capabilities of the Polynesians are legendary(c). The ancient Chinese employed magnetism(e) and in the cloudy North Atlantic, the Vikings used their ‘sunstones’(d).
In their book, Atlantis in America  Ivar Zapp & George Erikson claimed that the stone spheres of Costa Rica had a navigational function [p34] as Zapp discovered that the sightlines of all the stones remaining in their original positions, did point to important ancient sites such as Giza, Stonehenge and Easter Island!
A most imaginative proposal has come from Crichton E.M. Miller who proposed  that the ubiquitous Celtic Cross is an image of an ancient navigational device. He further claims that “This instrument can tell the time, find latitude and longitude, measure the angles of the stars, predict the solstices and equinoxes and measure the precession of the equinoxes. It can also find the ecliptic pole as well as the north and south poles; it can make maps and charts, design pyramids and henges and—used in combination with these sites—can record and predict the cycles of nature and time(f) “. Then for good measure, he proceeded to patent the device.

The Hall of Records (HoR) is a term used to describe an alleged repository of ancient wisdom, frequently claimed to be situated under the Sphinx at Giza. Today, the HoR is usually associated with the prognostications of Edgar Cayce who, in one of his trances, told us that there were three such repositories, near Bimini, the Yucatan and Giza.
Popular writers Robert Bauval and Graham Hancock were convinced that the HoR had been situated under the rear paws of the Sphinx in Keepers of Genesis , published as Message of the Sphinx in the USA. Ian Lawton & Chris Ogilvie-Herald have noted in Giza the Truth  how both Bauval and Hancock have modified their view of the HoR in a later video [p.400]. Cayce thought that the HoR would be found under the left paw of the Sphinx.
Lawton & Ogilvie-Herald also review the comments of other writers, both modern and ancient regarding the HoR. Their preliminary conclusion was “that it would appear that the weight of evidence supports the idea that secret records of mankind’s ancient past and knowledge do indeed exist in various locations in the world. However, the evidence linking them to Giza is far less substantial.” [p.242]
In 2000, Ralph Ellis announced his intention to lead an expedition to Mount Kailash in Nepal to find the Hall of Records!(a)

Gary A. David is an American independent researcher and author dealing with archaeological ruins and rock art of the American Southwest. His focus is on the Hopi tribe of northern Arizona and its archaeo-astronomy. Although he has not written directly about Atlantis, he has contributed a number of interesting papers relating to subjects peripheral to our study here. Most of these are available on the Academia.edu website(a).
David has also written about the Orion Correlation Theory (OCT) of Bauval & Gilbert, which claims that the alignment of the three stars in Orion’s ‘belt’ is reflected in the layout of the three principal pyramids at Giza.
>David has expanded on the OCT of Bauval & Gilbert identifying important sites throughout Egypt that he believes constituted a more extensive reference with other heavenly bodies in what he calls the Egyptian Stellar Template(e).<
He goes further and claims that he “stumbled across an Orion Correlation that the ancestral Hopi Indians constructed in Arizona from about 1050–1300 AD. In this case, every major star in the constellation corresponds to a specific masonry village site. The terrestrial replication of the celestial pattern is simply uncanny.” (b)
David has published an informative paper(c) on the Maltese Cross and its variants as found around the world. He pointed out its use in the Americas by the ancient Olmecs and has laid great emphasis on its place in the inherited culture of the Hopi people.
David has also highlighted the use of the swastika in a more benign way by the Hopi of northern Arizona along with its innocent use in other cultures including the Minoans, as well as in 20th century USA(d).
Ian Lawton (1959- ) is an English researcher focused on ancient history and spiritual philosophy. He is probably best known as the co-author with Chris Ogilvie-Herald of Giza: The Truth , which offers a sober forensic review of all the many and widely varied theories relating to the ancient structures on the Giza Plateau.>In it, Lawton was highly critical of Robert Bauval‘s Orion Correlation Theory (OCT) both in the book (chapter 9)(d) and in open correspondence between them.<
>However, Lawton was at the receiving end of criticism from the late John Anthony West in 2000, when West published an article in Atlantis Rising magazine that ended with a scornful “The point is that the facile assurances given by Ogilvie-Herald/Lawton endorsing the orthodox view are illegitimate, their exclusion of contrary, genuinely informed opinion is typical of their selective bogus scholarship, and their long-winded acoustic levitation hypothesis is pure speculation and self-contradictory besides. We still don’t know how the pyramids were built/ Period. Full stop.”(e)<
Lawton’s second book, Genesis Unveiled , has been described as containing “remarkable new insights into the spirituality of the pre-flood human race”. Chapter 13 takes a somewhat generous view of Blavatsky and Theosophy(c).
He subsequently made changes(a) to the content and, in my opinion, opportunistically re-titled it as Atlantis: The Truth! In it Lawton has focused on prediluvian races, citing, with reservations, the work of Stephen Oppenheimer, Arysio dos Santos and Frank Joseph, which when added to Lawton’s research, he concludes that “it’s nevertheless interesting that all four of us have independently arrived at the same conclusion about the broad whereabouts of any forgotten race.” He argues that the location of such a race was in the general region of Sunda and Sahul Shelves.

The Nazca Lines of Peru>were systematically studied by Toribio Mejia Xesspe, a Peruvian archaeologist, beginning in 1926, but the geoglyphs only gained widespread attention when pilots flew over them in the 1930s.
Paul Kosok (1896-1959) was also claimed as the first to carry out a professional study of the Nazca drawing in 1939. He was assisted a year later by Maria Reiche (1903-1998) who devoted the rest of her life to the study of Nazca. Kosok continued his research there until 1949.
The purpose of the geoglyphs has generated reams of commentary, from the nonsensical of von Däniken to the more profound of Reiche.
“In the late 1960s and early 1970s, however, other researchers, including American astronomer Gerald Hawkins, examined the Nazca Lines and disagreed with the astronomical explanation for the geoglyphs. They also poked holes in other far-out explanations, such as those relating to aliens or ancient astronauts(f).”<
However, for sheer complexity, I must direct you to the work of Czech-Canadian Jiri Mruzek. He has managed to link the Monkey geoglyph at Nazca with the layout of the Giza pyramids and a 14,000-year-old cave drawing at La Marche in France; all under the banner of ‘Seal of Atlantis’!!!(a)
In 2018, it was announced that another fifty Nazca style geoglyphs had been discovered in the adjacent province of Palpa(b). This number was subsequently increased to 142(c).
In February 2020, Frank Maglione Nicholson, Ken Phungrasamee & David Grimason, collectively known as The Nazca Group(d), published The Nazca Great Circle Map Hypothesis. Their claim is that “The lines and geoglyphs carved into the Nazca plateau represent a map of the Earth. The map is a Great Circle Map: a gnomonic projection with the center of the Earth as its cartographic view point. Each line on the Nazca Plateau represents a great circle of navigation centered at the center of the Earth and encircling the entire planet. The majority of the lines on the Nazca Plateau radiate from five loci of origin called radial centers.”
Another 2020 article(e) by Laszlo Arvay concluded that “the Nazca Plateau could be the largest astronomical atlas in the world. If that is so, Paul Kosok was right after all and on a much greater scale as he ever thought possible.”

Miquel Pérez-Sánchez is a Spanish architect with a fascination with the Giza pyramids(a). He is now advocating an idea that was in vogue in the 19th century, namely that information, astronomic, historic and prophetic, were encoded in the measurements of the structure of the Great Pyramid. However, he has gone further by adding to it the ancient system of gematria, where every letter in an alphabet has a numerical value. Pérez-Sánchez has reversed this and translated numbers ‘identified’ in the Pyramid back into letters. One of these was equivalent to ‘Atlantis’! Whether this is in English, Greek or Hebrew is not clear.
Another of his startling claims is that the Great Pyramid was surmounted by a sphere, an idea that understandably drew highly critical comments (e)(f).
The byoweb.net website added that “After the discovery and publication of his first book, the author and his team are now looking for funding to the Atlantis project, including a campaign of underwater archaeology in the Mediterranean Sea where they are sure to have located the mythical island described by Plato.”
Further comments and interesting images are to be seen on ancient-code.com, including Pérez-Sánchez’s statement(b) that “the Great Sphinx is not contemporary with the pyramids that surround it, but it is the product of a much earlier civilization that shaped and carved it around the eight millennium BC.”
Pérez-Sánchez has recorded all his ‘discoveries’ in his book, La Gran Pirámide, clave secreta del pasado and provides some supporting videos(c) of his lectures(d).
>A critical commentator offered the following information (originally in Spanish). “The Catalan architect has brought together his collection of absurdities, comparable to those of (Ben) Carson, in his work La Gran Pirámide, clau secreta del passat, for which, presented as a thesis, he obtained a doctorate laude in 2012 from the Polytechnic University of Catalonia (UPC). The website on which Pérez-Sánchez sells his thesis in ten volumes in Spanish is subsidized by the Ministry of Culture . In April, the Polytechnic University of Madrid (UPM) and the Athenaeum of that city sponsored the presentation of the work in the capital of Spain and, in May, the pseudo-historian did the same in Seville at the Casa de la Ciencia del Consejo Superior de Scientific Research (CSIC). Is there room for greater insults to science, to culture?”(g) <

The Cygnus Constellation was the location of a supernova that inspired the story of Phaeton, as related to Solon by the priests at Sais, according to Michael A. Cahill in his two-volume Paradise Rediscovered [818/9].
Andrew Collins has also written on the place of the constellation Cygnus in prehistoric consciousness. Arising from this study, it appears that the position of the Cygnus stars correlates more accurately with the Giza pyramids than those of Orion, which was proposed some years ago by Robert Bauval. Collins continues with the Cygnus-Giza connection in a subsequent offering, Beneath the Pyramids. Derek Cunningham has echoed(a) some of Collins’ work suggesting that there existed in ancient times a World Map based on the Cygnus constellation!
Collins has also suggested that a suspected Black Hole in Cygnus Constellation is thought to be the source of cosmic rays that changed evolution and kick-started religion(d)!
Anthony Murphy and Richard Moore have also written(b) about the Cygnus Constellation and a possible link with Ireland’s Newgrange.>This idea was echoed in a recent episode of Ancient Aliens (S18E17)(f).<Paul Dunbavin also touched on the possible connection between swans in Irish mythology and astronomical events(e).
Freddy Silva has endeavoured to link Cygnus with the Osirion in Abydos in a 2019 article(c) in which he dated the structure to 10,500 BC.
Geodesy is usually defined as the measurement and mapping of the Earth.>James R. Smith, the author of Introduction to Geodesy  has conflated several definitions to produce “Geodesy, from the Greek, literally means dividing the earth, and as a first objective, the practice of geodesy should provide an accurate framework for the control of national topographical surveys. Thus geodesy is the science that determines the figure of the earth and the interrelation of selected points on its surface by either direct or indirect techniques. These characteristics further make it a branch of applied mathematics, one that must include observations that can be used to determine the size and shape of the earth and the definition of coordinate systems for threedimensional positioning; the variation of phenomena near to or on the surface, such as gravity, tides, earth rotation, crustal movement, and deflection of the plumb line; together with units of measurement and methods of representing the curved earth surface on a flat sheet of paper.”<
>Geodesy as a science can be traced back to Pythagoras (6th cent. BC), who was thought to be the first to propose the sphericity of the Earth. Aristotle & Archimedes were apparently the first the offer a figure for the diameter of the Earth, suggesting 400,000 and 300,000 stades respectively. The difference might be partly explained by the use of a different length of stade.<
Later, Eratosthenes (276 BC– 195 BC) offered another early attempt to determine the dimensions of our Earth and succeeded with remarkable accuracy.
A controversial aspect of modern geodesy is the claim that many ancient sites were deliberately established at locations that had a specific geodetic relationship to each other and/or the dimensions of the Earth. For example(a) in ancient Egypt, from Giza to the Equator is 1/12th the circumference of the Earth, Amarna to the Equator is 1/13th, Luxor 1/14th and Philae 1/15th! Graham Hancock in his Heaven’s Mirror pointed to similar relationships around the globe suggesting a possible world grid. This idea of a world grid has a number of supporters but is often classified as a ‘fringe’ interest due to the attempt by some to link gridlines with UFOs and their use of the grid as a power source(w).
Possibly related features may be the ley lines identified by Alfred Watkins in Britain(c)(g), the Alesia alignments in France discovered by Xavier Guichard(b) and/or the Heilige Linien of Germany claimed by Wilhelm Teudt(aa).
Heinz Kaminski claimed to have discovered a megalithic grid system that stretched from Stonehenge across Europe with an east-west and north-south orientation and referred to as the Stonehenge/Wormbach System(h).
Even more exotic is the ancient Raetiastone navigation system rediscovered by Gerhard Pirchl (1942-2013) and outlined in a book by  Thomas Walli(ae).
Ashley Cowie has published a paper(ac) related to Alesia and the work of Guichard and others, as well as his own investigations.
I should also point out that Marcel Mestdagh also identified a form of a road system, laid out in giant ovals with radials in France. At the centre of these ovals was the ancient city of Sens. Philip Coppens informs us [1275.184] that a further strange discovery by Mestdagh was that this ancient road network, centred on Sens, was mirrored by a similar network of roads in England centred on Nottingham!
‘The Way of Virachoca’ in the Andes which runs through Tiwanaku and is oriented exactly 45° west of true north and runs for over 1000 miles, has been studied by Maria Scholten d’Ebneth  in the 1970s and expanded on by a number of Spanish speaking commentators and is now the subject of an article by Dave Truman(x).
In 1973, three Russians, engineers Valery Makarov and Vyacheslav Morozov along with Nikolay Goncharov, an artist, published in Russian an article with the eye-catching title of Is the Earth a Giant Crystal? (y) This was probably the earliest presentation of an earth grid based on ancient historical sites. A brief history of the earth grid theories that emerged around this time is available online(z). There is now a Russian geodesy website with an English translation(ab).
David Hatcher Childress published his Anti-Gravity and the World Grid  in 1993, with the modest claim that he “proves that the earth is surrounded by an intricate electronic grid network offering free energy.” Obviously, Childress’ understanding of ‘proof’ is different to mine, as the only proof required is the production of some of this free energy, which he has not done.
Tom Brooks entered the fray with a study of 1500 prehistoric sites and his conclusion that the inhabitants of ancient Britain had designed a navigation system based on a grid of isosceles triangles(i). Brooks has gone a step further and speculatively claimed that the accuracy of this geometry-based system could only have been designed through “extraterrestrial intervention”(r). This concept is explored more fully in his latest book, Seeing Around Corners: Geometry in Stone Age Britain  and in a series of video clips(s). A more critical view of Brooks’ ideas is also available on the Internet(j).
Some years ago a former employee of a NASA sub-contractor, Maurice Chatelain claimed that within a 450-mile radius of the Aegean island of Delos that 13 mystical sites, when connected by straight lines formed a perfect Maltese Cross(u)!
Others such as Livio Stecchini(d) and Jim Alison(e) using geodetic calculations have identified São Tomé and Cape Verde respectively as the location of Atlantis. I must also include Hugo Kennes, a Belgian researcher with a passionate interest in global grids and sacred geometry(l). Kennes has also informed me of a new Facebook group(q) dealing with all aspects of the subject, as well as another(v) that includes submerged cities and other features.
Anyone interested in pursuing a study of this subject might like to look over James Q. Jacobs’ archaeogeodesy website(f) as well as the BioGeometry website (m).
If you have pursued all the links so far, you can pamper yourself further with a paper(k) by William Becker and Beth Hagens(n). Another researcher in this field is Dan Shaw whose website(o) gives a good overview of the subject.
Jean-Pierre Lacroix added his weight to the debate with his 1998 paper entitled The Mapmakers from the Ice Age(t).
A global network of sacred sites was also put forward by Rand Flem-Ath & Colin Wilson in The Atlantis Blueprint . This book was intended as a sequel to When the Sky Fell , but generally wandered off into other areas after the first couple of chapters.
I am somewhat sceptical about certain aspects of geodesy, particularly some of the claims of a world grid. However, it does raise many questions that require further study and explanation. In this connection, I would recommend John Sase’s Curious Alignments  as a good starting point. He confirms the work of Guichard and also offers a range of his own discoveries in the Great Lakes region.
In February 2020, Frank Maglione Nicholson, Ken Phungrasamee & David Grimason, collectively known as The Nazca Group(ad), published The Nazca Great Circle Map Hypothesis. Their claim is that “The lines and geoglyphs carved into the Nazca plateau represent a map of the Earth. The map is a Great Circle Map: a gnomonic projection with the center of the Earth as its cartographic viewpoint. Each line on the Nazca Plateau represents a great circle of navigation centred at the centre of the Earth and encircling the entire planet. The majority of the lines on the Nazca Plateau radiate from five loci of origin called radial centres.” I found this rather esoteric proposition difficult to absorb.
Arturo Villamarin has published many books  and papers(af)(ag) in which the geometry and astronomy of archaeological monuments; Göbekli Tepe, Stonehenge, Teotihuacán and Mohenjo Daro, among others, are discussed.

Gernot L. Geise (1945- ) & Reinhard Prahl (1967- ) Geise has written on a number of mysteries ancient and modern(b), the Pyramids, Revised Chronologies and three books on the alleged moon landing hoax(c).
As a guest author he offered a controversial paper on the Atlantisforschung.de website with the self-explanatory title of ‘The Giza pyramids were not built by ancient Egyptians’(d).
He has contributed regularly to the German EFODON magazine, of which he is a founding member.
Prahl has written on possible connections between the Guanches and the ancient Egyptians(a) and has collaborated with Geise to produce Auf der Suche nach der Mutterkultur (In Search of the Mother Culture)  in which they support the idea of Atlantis in the Antarctic.

The Atlantis Blueprint by Rand Flem-Ath and Colin Wilson, is a follow-up to the highly controversial, When the Sky Fell by Rand Flem-Ath and his wife Rose. The focus of this book is on the claimed existence of a worldwide network that incorporates such famous sites as Giza, Machu Picchu, Easter Island etc., etc. The authors claim that these monuments were arranged in a global geometric pattern by an advanced ancient civilisation that included Plato’s Atlantis. This breathtaking idea is not one that I can subscribe to, as it seeks to tie up too many of the mysterious loose ends of ancient history at one fell swoop.
