Cartography is defined by The International Cartographic Association “as the discipline dealing with the conception, production, dissemination and study of maps.” The earliest land maps can be traced back to Babylonia around 1400 BC. In 2017, Evangelos Livieratos, Professor Emeritus of the Aristotelian University of Thessaloniki Cartography Department, offered evidence that the ancient Greeks were the first to develop a primitive GPS system, using the stars and their relationship with the earth’s surface(g).
The BBC offered an overview on the development of cartography since the 15th century(k).
The subject entered the Atlantis arena in 1665 with the publication of a speculative map(a) of Atlantis, situated in the Atlantic, by Athanasius Kircher. It was allegedly based on earlier Egyptian maps, but unfortunately there has been no corroborative evidence to support this contention. Kircher’s map had been used to bolster a variety of location theories – Azores, Russia, Baffin Bay and Greenland, Kircher himself favoured the Azores.
Hy-Brasil was reputed to be an island to the west of Ireland and frequently associated with the story of Atlantis. The Genoese cartographer, Angellino de Dalorto (fl.1339), placed Hy-Brasil on a map as early as 1325.*It is further claimed that Dalorto, sometimes known as Angelino Dulcert, also depicted Australia on his 1339 portolan chart(l).*
However, on some 15th century maps, the islands of the Azores appear as Isola de Brazil, or Insulla de Brazil. Apparently, it was not until as late as 1865 that Hy-Brasil was finally removed from official naval charts.
Another feature on ancient that can confuse is the placing of south at the top of old charts, two examples of which are Kircher’s map of Atlantis and Al-Idrisi’s Tabula Rogeriana. Caroline Williams has an interesting article(e) on the BBC website relating to the history of map orientation.
The unreliability of early maps is highlighted by the manner in which California has been depicted. In the 16th century the maps of both Mercator and Ortelius correctly show Baja California as a peninsula, but in the following 17th and 18th centuries it became an island on many charts despite written evidence to the contrary. There is a website dedicated to a study of the ‘island of California’(I), which incongruously ends with a brief reference to Atlantis, placing it in the Atlantic in the Region of Bermuda.
Donald S. Johnson in his well illustrated Phantom Islands of the Atlantic discusses in detail the history of seven legendary islands. This fascinating book offers every reason to treat the details of early cartography with extreme caution.
Further difficulties with old cartography are the result of early mapmakers having a dread of blank spaces, a view outlined in a recent (Nov. 2017) National Geographic online article(h).
The most widely referred to map in relation to Atlantis as well as advanced ancient civilisations is the Piri Reis chart. This arguably depicts an ice-free Antarctica and has been used to develop the idea that Atlantis had been located there and was destroyed when a sudden pole shift caused the southern icecap to move to its present position. Rose and Rand Flem-Ath are the leading proponents of this idea based on the findings of Charles Hapgood. Other maps such as that of Phillipe Buache, the renowned French geographer, published in 1737, are claimed to show an ice-free Antarctica.
It is claimed by Ivan Petricevic that The Ben Zara Map of 1487 “displays remnants of glaciers in Britain, but also extremely detailed depictions of islands in the Mediterranean and Aegean seas. Today, these islands still exist, but due to rising water levels, these are now underwater.”(j)
Dale Drinnon has an interesting, if speculative, article on ancient maps and their possible relevance to the story of Atlantis(b). Another article in Atlantis Rising magazine (July/August 2014) argues that the quality of medieval navigational charts (portolans) of the Mediterranean exceeded the capabilities of the instruments and knowledge in the region at that time and must have originated elsewhere. However, Roel Nicolai at Holland’s Utrecht University, who expressed these sentiments, was unwilling to nominate Atlantis as the source of the maps(c).
Enrique García Barthe is an Argentinian cartographer who has an interesting Spanish/English website(d) dealing with pre-Columbian maps. Although many people have heard of the Piri Reis Map and the controversy surrounding it, García Barthe introduces a lot of new maps that appear to complement Piri Reis.
In 2015, Melissa Brooks used the data in the Atlantipedia chronology of location theories to develop a map(f) showing the distribution and level of support for the various theories on offer.

The Sahara Desert and in particular its northern regions have attracted its share of attention from Atlantis investigators. However unlikely it may appear as a possible location for Atlantis it must be kept in mind that the Sahara of prehistory was very different from what we see today. Not only was it wetter at various periods in the past, but also there is clear evidence for the existence of a large inland sea extending across the borders of modern Algeria and Tunisia. This evidence is in the form of the chottsor salt flats in both countries. This proposed sea is considered by some to have been the Lake Tritonis referred to by classical writers. It is suggested that some form of tectonic/seismic activity, common in the region, was responsible for isolating this body of seawater from the Mediterranean and eventually turning it into the salt flats we see today.
An even more extensive inland sea, further south, was proposed by Ali Bey el Abbassi and based on his theory a map was published in 1802 which can be viewed online(c).
More recently, Riaan Booysen has published an illustrated paper on the ancient inland Saharan seas as indicated on the 16th century maps of Mercator and Ortelius(i). King’s College London runs The Sahara Megalakes Project which studies the Megalakes and the Saharan Palaeoclimate record(m).
A 2013 report in New Scientist magazine(d) revealed that 100,000 years ago the Sahara had been home to three large rivers that flowed northward, which probably provided migration routes for our ancestors.
Other studies(h) have shown the previous existence of a huge river system in the Western Sahara, which flowed into the Atlantic on the Mauritanian coast.
An article in the Sept. 2008 edition of National Geographic pointed out that the Saharan climate has been similar for the past 70,000 years except for a period beginning 12,000 years ago when a number of factors combined to alter this fact. A northerly shift by seasonal monsoons brought additional rain to an area the size of contiguous USA. This period of a greener Sahara lasted until around 4,500 years ago. Henri Lhote contributed an article to the Reader’s Digest’s, The World’s Last Mysteries , regarding the ‘green’ Sahara that existed prior to 2500 BC.
An interesting question might be; what happened circa 2500 BC to cause this reversal? Some have suggested a connection between the aridification of the Sahara and the destruction of Atlantis!
More recently, human activity has been blamed as a major contributory factor for the desertification of the Sahara region less than 10,000 years ago.(n)
Related to the above is a recent study of sediments off the west coast of Africa, which resulted in the discovery of what was “primarily a new “beat,” in which the Sahara vacillated between wet and dry climates every 20,000 years, in sync with the region’s monsoon activity and the periodic tilting of the Earth.” (o)
In 1868, it was proposed by D.A. Godron, the French botanist, that the Sahara was the location of Atlantis. In 2003, the non-existent archaeologist Dr.Carla Sage announced that she was hoping to lead an international expedition to the Sahara in search of Atlantis. Her contention was that “Atlantis was the capital of a vast North African empire with ports on the Gulf of Sidra”. This report is now confirmed to have been a hoax! I am indebted to Stel Pavlou for uncovering the origin of this story(e).
Gary Gilligan, the well-known catastrophist, wrote a thought-provoking article(k) on the origin of the Saharan sands, which he claims are extraterrestrial in origin and expands on the idea in his 2016 book Extraterrestrial Sands .
David Mattingly, an archaeologist at Leicester University has found that an ancient people known as the Garamantes had an extensive civilisation in the Sahara(l). He has evidence of at least three cities and twenty other settlements. The Garamantes reached their peak around 100 BC and then gradually diminished in influence as fossil water supplies reduced until in the 7th century AD they were subjected to Islamic domination. Some researchers such as Frank Joseph have identified the Garamantes as being linked with the Sea Peoples. Bob Idjennaden has published short but informative Kindle books about both the Garamantes  and the Sea Peoples , without a suggestion of any connection between the two.
The discovery of the megalithic structures discovered at Nabta Playa (Nabta Lake) in the Egyptian Sahara has provided evidence for the existence of a sophisticated society in that area around 5000 BC. In the same region, near the Dakhleh Oasis, archaeologists have produced data that supports the idea that pre-Pharaonic Egypt had Desert Origins rather than being an importation from Mesopotamia or elsewhere(a).
Nabta Playa is not unique, in fact the largest megalithic ellipse in the world is to be found at Mzorah, 27 km from Lixus in Morocco(b). It appears that the construction methods employed at both Mezorah and Nabta Playa are both similar to that used in the British Isles. An even more impressive site is Adam’s Calendar in South Africa which has been claimed as 75,000-250,000 years old.
West of Cairo near the border with Libya is the Siwa Oasis, where it has now been demonstrated that “it is in fact home to one of Ancient Egypt’s astounding solar-calendar technologies– the solar equinox alignment between the Timasirayn Temple and the Temple of Amun Oracle in Aghurmi.”(j).
I think we can expect further exciting discoveries in the Sahara leading to a clearer picture of the prehistoric cultures of the region and what connections there are, if any, with Plato’s Atlantis. In the meanwhile in the Eastern Egyptian Desert, Douglas Brewer, a professor of archaeology at the University of Illinois, has discovered over 1,000 examples of rock art, including numerous depictions of boats although the sites, so far undisclosed, are remote from water.
Even more remarkable is the report(e) of March 2015 that a survey of the Messak Settafet escarpment in the central Sahara revealed that there were enough discarded stone tools in the region “to build more than one Great Pyramid for every square kilometre of land on the continent”! Coincidentally, around the same time it was reported that over a thousand stone tools had been found in the Northern Utah Desert(g). What the Utah discovery lacked in quantity was made up for in quality with the finding of the largest known Haskett point spear head, measuring around nine inches in length.
