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 had 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).
*When asked in a recent interview what he meant by ‘advanced civilisationGraham Hancock revealed(u) that “I think we’re talking about a civilization – more than 12,000 years ago – which was as advanced as our civilization was, say in the late 18th century or early 19th century. In other words, they could navigate the world, they could explore the world, they could measure the world accurately, they had precise astronomy, they could create beautiful maps that were accurate in terms of latitude and longitude. That kind of level of civilization.”*
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 Strait of Gibraltar according to Greek mythology was created by Herakles. Neville Chipulina explains that “it seems that the person responsible for the myths about Hercules was Peisander of Rhodes, a 7th century BC Greek epic poet who apparently got the story from an unknown Pisinus of Lindus who almost certainly plagiarised it from somebody else. In other words it’s a pretty old story.”(c)
The Strait is very much a part of many current Atlantis theories. Primarily, it is contended that the region itself held the location of Atlantis. This is based on Plato’s statement that Eumelos, also known as Gadeirus, the twin brother of Atlas the first king of Atlantis gave his name to Gades, known today as Cadiz. Andalusia in Southern Spain has been the focus of attention for over a hundred years. In recent years Georgeos Diaz-Montexano and his rival Jacques Colina- Girard have been investigating the waters of the Strait itself while south of the Strait Jonas Bergman has advanced his theory that Atlantis was located just across the Strait in Morocco.
Although there is general acceptance that the Pillars of Heracles had their final resting place in the vicinity of the Strait of Gibraltar, it must be noted that there have been others candidates at different times with equally valid claims. The location of the ‘Pillars’ referred to by Plato at the time of Atlantis is the subject of continuing debate.
Strato, the philosopher, quoted by Strabo, spoke of a dam separating the Atlantic and the Mediterranean being breached by a cataclysm. This idea was reinforced by comment of Seneca. Furthermore, a number of Arabic writers, including Al-Mas’udi, Al-Biruni and Al-Idrisi, have all concurred with this idea of a Gibraltar land bridge in late prehistory.
A more radical theory is that of Paulino Zamarro who contends that the Strait was in fact closed by a landbridge during the last Ice Age because of the lower sea levels together with silting. When the waters rose and breached the landbridge, he believes that, the flood submerged Atlantis, which he situates in the Aegean. Others support Zamarro’s idea of a Gibraltar Dam amongst whom are Constantin Benetatos and Joseph S. Ellul.
Terry Westerman on his heavily illustrated website surveys impact craters globally. He suggests that “The Strait of Gibraltar was formed by two meteor impacts. The first blasted the round area in the western Mediterranean Sea to form a land bridge between Spain and Morocco.” He maintains that a second impact broke the landbridge around 5.33 million years ago, creating what is called the Zanclean Flood which refilled the then desiccated Mediterranean(d).
>A German language website(a) presented some of the following data+, apparently recording the dramatic widening of the Strait of Gibraltar between 400 BC and 400 AD. The same list was included in the ‘Strait of Gibraltar’ entry of the German Wikipedia(b) until a few years ago. It has since been removed.
+Damastes of Sigeum, circa 400 BC. – about 1.3 km
+Pseudo-Skylax, probably fourth Century BC – about 1.3 km
*Turiano Greslio? 300BC – 8.0 km
*+Titus Livius (Livy) 59 BC- 17 AD – 10.5 km
+Strabo 63 BC- 24 AD – from 9.5 to 13.0 km
+Pomponius Mela , 50 AD – about the 15.0 km
+Pliny the Elder , 50 AD – about 15.0 km
*+Victor Vicensa (*Vitensa?), 400 AD – about 18 km
The above figures suggest that in the latter half of the first millennium BC, the Strait of Gibraltar was gradually widened. Nevertheless, until the methods used and all the data on offer have been verified, the idea must be treated with great caution.
My list had orignally included Euctemon, the 5th century BC Athenian astronomer, however, Werner E. Friedrich notes that Euctemon was referring to the Sea of Marmara near the entrance to the Black Sea [0695.38].<
However, more recently, John Jensen Jnr. has offered a comparable, if shorter, numbers of dates showing the reducing width of the strait the further back you go until 3450 YBP, when he believes that a landbridge there was breached(e).
Georgeos Diaz-Montexano has also referred to the descriptions by ancient writers of the Strait of Gibraltar indicating a width of around two kilometres. Unfortunately, he does not cite references(f). He also is sympathetic to the existence an earlier landbridge at Gibraltar.
Mediterranean Sea Level. There is general acceptance that, on more than one occasion, the Strait of Gibraltar was closed completely. Tectonic plate movement, worldwide sea level drops due to the onset of Ice Age glaciation or a combination of both, could have caused this. There is also clear undisputed evidence that the Mediterranean Sea has dried out completely on a number of occasions. What is not clear is when the last desiccation or partial drying-out of the Mediterranean ended. The conventional date given for the last breaching of a Gibraltar Dam is 5 million years ago. However, there is a small but growing opinion that there was a more recent breach of a dam within the memory of modern man and preserved in history and myth.
>Not only have sea levels changed, but a 2020 report has now offered evidence that the Mediterranean was over three degrees hotter 2,000 years ago and that it remained hotter for about 500 years during the time of the Roman Empire(c).<
Where one theory on the location of Atlantis is concerned, the existence of a Gibraltar dam before the end of the last Ice Age is critical, namely that Atlantis was situated near modern Cyprus. The site chosen by author Robert Sarmast is 1650 metres beneath the present level of the Mediterranean. His theory is totally dependent on proving the existence of this dam. It would seem prudent to have carried out a more detailed study of the evidence for a relatively recent removal of the dam before engaging in a very costly exploration over a mile under the eastern Mediterranean.
There are a number of facts that appear to suggest a more recent Mediterranean inundation but even collectively they do not offer any more than circumstantial evidence.
(i) The Mediterranean sea level must have dropped by as much as from 150 to 300 meters or more. Several years ago, by chance divers found submerged entrances (below sea level) in Southern France, which subsequently led them to discover the now famous prehistoric cave paintings there. There are many man-made stone structures around the Mediterranean that are now under water as well.
Cosquer Cave, near Marseilles, has its entrance 37 metres underwater. It contains several dozen works painted between 25000-17000 BC. The opening was once several miles inland until about 10000 BC when the sea began to rise at the end of the last Ice Age. It has been estimated that that it was originally at a height of 80 metres above sea level, according to anthropologist, James Q. Jacobs(a). This cave art depicts the Auk, which had never been found this far north.
(ii) Submerged Maltese structures, although their inundation may have been caused by local seismic activity rather than global sea level changes.
(iv) A modern Guide to Provence(b) also claims a relatively recent removal of the Gibraltar land bridge.
(vi) The sunken port of ancient Syedra in Turkey.
(b) Landmark Visitors Guide – Provence & Côte D’Azure by Richard Sale. (p.16)
A Gibraltar Landbridge or Dam is generally accepted to have existed on a number of occasions during the earth’s history. There is a broad consensus among geologists that the last time a totally enclosed and desiccated Mediterranean had its barrier to the Atlantic breached was around 5.3 million years ago. One well-illustrated website(h) attributes this rupture to a meteor impact!
Today, we generally think of the Strait of Gibraltar as the only gateway between the Atlantic and the Mediterranean, while in fact there is evidence that millions of years ago the Strait was closed but that there were other access routes between the two bodies of water(n). The Betic Corridor in the north, which later became part of the Spanish Guadalquivir Basin and the Rifian Corridor in the south, in what is now Morocco.
However, a number of experts in different fields (noted by Van Sertima) have opted to suggest a more recent landbridge, perhaps 120,000 years ago, in order to explain some of the faunal migrations from Africa to the Iberian Peninsula. The 18th century writer Georges-Louis Buffon speculated as early as 1749 on the existence of a Gibraltar Dam. Alexander Braghine refers[156.21] to a Bishop Tollerat, a contemporary of Bory de Saint Vincent, claiming that a Gibraltar landbridgen was breached by an earthquake and led to the submergence of Atlantis. Unfortunately, I have been unable to track down Tollerat.
Even popular fiction featured the idea of a Gibraltar landbridge. In 1869, Mark Twain in chapter 7 of Innocents Abroad voiced a then current theory that there had been dry land between Gibraltar and North Africa allowing the passage northward of the so-called ‘Barbary apes’ that live on the ‘Rock’ today.
In 1921, H.G.Wells, in The Outline of History, offered a graphic, although speculative, description of the breaching of the Gibraltar Dam(g). He wrote that “This refilling of the Mediterranean, which by the rough chronology we are employing in this book may have happened somewhen between 30,000 and 10,000 B.C., must have been one of the greatest single events in the pre-history our race.”
Manuel Sánchez de Ocaña was the Spanish Lieuenant General during the 1909 war in Africa. In a rare 1935 book, Accion de España en Africa(a) (Spanish Action in Africa) he refers to the ancient isthmus that linked Spain and North Africa as well as landbridges linking Europe and America on which he believed Atlantis had been situated.
François de Sarre (1947- ) a noted French evolutionary zoologist who has proposed that a landbridge had existed at Gibraltar, which was only destroyed in relatively recent times, possibly in the second millennium BC. In support of his view he quotes Pomponius Mela, Diodorus Siculus and Pliny.*He has also published a paper, in English, supporting his opinion with a spectrum of faunal evidence(k).*
Others have ventured further and proposed that a dam existed within the experience of man and that its last destruction led to the sinking of Atlantis that many claim was located in the Mediterranean. H. S. Bellamy refers to Strato quoted by Strabo, declaring that originally the strait did not exist but that the barrier was broken through in a cataclysm. Bellamy also quotes Seneca describing how Spain was separated from Africa by earthquakes. Neither of these references could have originated without human witnesses.
Alexander Braghine also added to the idea of a relatively recent landbridge when he wrote[156.139] “We possess a whole series of records of the width of these Straits, left by ancient and medieval writers of various centuries. At the beginning of the fifth century B.C. the width was only half a mile, but the writer Euton in 400 B.C., estimated it at 4 miles; Turiano Greslio, in 300 B.C., at 5 miles; and Titus Livius, at the beginning of the Christian Era, at 7 miles. Victor Vitensa, in A.D. 400, gives the width of the Straits as equal to 12 miles, and at present it is 15 miles wide.”
C. M. Hardy subscribed to the view that there had been a dam at Gibraltar that was breached around 4500 BC with such a force that it also led to the destruction of a landbridge between Tunisia and Italy. He believed that remnants of Atlantis will be found in the seas around Greece.
C. S. Rafinesque, the famous naturalist, claimed that there was a Gibraltar landbridge that was destroyed 654 years after Noah’s Flood. These claims are to be found in chapter 14 of Vol II of The American Nations published in 1836. This volume can now be downloaded for free(e). A creationist website(i) links the breaching of the landbridge with Noah’s Deluge, which the author claims not only flooded the Mediterranean but also spilled into the Black Sea, the Red Sea and also the Persian Gulf. (see below)
The standard argument against the landbridge theory is that although the Atlantic was dramatically lower during the last Ice Age it was not sufficient to expose a land bridge between Spain and Africa at Gibraltar. However, it should be noted that the underwater sill between the Atlantic and the Mediterranean would have been much higher than now. When we consider that the breaching of a landbridge at Gibraltar would have caused an incredible flow of water through the breach (hundreds of times the flow of Niagara Falls), scouring its bottom, so that by the time the levels in the Atlantic and the Mediterranean had equalised, the erosion of the sill between them would have been considerable and when viewed today would misleadingly suggest that the Mediterranean had not have been completely cut off from the Atlantic during the last Ice Age. For the future, the consequence of this is that when (not if) the next Ice Age begins the ocean levels will have to drop even lower if the Mediterranean is to be isolated from the Atlantic once again. An example of what a sudden release of large bodies of water can do is visible in the scablands of North America, created by the breaching of the glacial dam retaining Lake Missoula.
The Spanish researcher Paulino Zamarro contends, in his 2000 book, Del Estrecho de Gibraltar a la Atlantida that a Gibraltar dam was created by silting when the Atlantic was very much lower during the last Ice Age and that it lasted until 7,500 years ago when it was breached and destroyed Atlantis, which he locates in the Cyclades, with the island of Melos containing its capital city. Details of his theory can be found on the Internet(d). A larger version of Zamarro’s map is shown below.
Other researchers such as Constantin Benetatos maintain that this idea is supported by comments of ancient writers who suggest that at one time the Mediterranean had no existence. The philosopher Strato supported by Seneca refer to the sundering of such a dam linking Europe and Africa. The same idea was expressed by Diodorus Siculus, who said that Africa and Europe were joined and separated by Heracles. Such ideas could only have arisen if there had been a Gibraltar Dam far more recently than the conventionally accepted 5.3 million years ago. The lowering of the ocean levels at the beginning of the last Ice Age and the exposure of a landbridge or dam between Spain and Morocco would have had the effect of drying out the Mediterranean due to the fact that loss of water through evaporation in the region is greater than the amount of water from rivers that feed into it.
It is worth considering that although the catastrophic breaching of the Bosporus and consequent expansion of the Black Sea is generally accepted as fact, there are no specific legends to support it apart from a reappraisal of the Flood of Noah. Therefore, it is not unreasonable to point out that a lack of local myth or legend relating to a breaching of a Gibraltar Dam is not proof that such an event did not occur. Furthermore, the area around the mouth of the Mediterranean is geologically unstable and could have been subjected to seismic activity that could have breached or even blocked the strait.
Alberto Arecchi agrees(a) with the concept of an historical land bridge at Gibraltar, but places its breach to around 2300 BC. As already intimated, Constantin Benetatos also believes(b) in the existence of the Gibraltar Dam. Joseph S. Ellul the Maltese writer was probable the first modern author to link the breaching of a Gibraltar landbridge with the destruction of Atlantis, which he claims to have been located adjacent to Malta. He identifies this submergence of Atlantis by the waters of the Atlantic with Noah’s Flood. Ellul interprets Genesis 7:11, 8:2, which refers to the “fountains of the great deep” bursting forth, as a reference to the collapse of the Gibraltar Dam. David Hatcher Childress also supports the idea of such a landbridge and has ventured a date of around 9000 BC for its collapse[620.261] and the consequent flooding of a desiccated Mediterranean.
Georgeos Diaz-Montexano, who has been searching for Atlantis off the coast of Spain and Gibraltar, has favourably referred to Zamarro’s silting theory and included the illustration, shown above, from Zamarro’s book on his websites. A further reference to silting can be read on another website(f).
When the Mediterranean eventually filled up, it is highly probable that it was then that the pressure of its waters led to the flooding of the Black Sea. It is reported that there are scouring marks at the entrance to the Black Sea that are very similar to those at Gibraltar. The date of the putative collapse of the Gibraltar Dam would therefore be marginally earlier, while the Mediterranean basins filled, than the accepted date for the breaching of the Bosporus currently calculated to have been around 5600 BC.
Robert Sarmast’s apparently dormant theory of Atlantis submerged off the coast of Cyprus under what is now a mile of water is totally dependent on the existence of a Gibraltar Dam during the last Ice Age and it being subsequently breached when the level of the Atlantic rose or the even more improbable lowering of the seafloor by a mile, as a consequence of seismic/tectonic activity in the region.
On the basis of evidence(c) offered by the quoted classical writers, the fact that sea levels rose hundreds of feet after the last Ice Age and examples of water damage to temples on elevated ground in Malta and nuraghi in Sardinia it is not unreasonable to conclude that a rupturing of a landbridge at Gibraltar within the last ten thousand year was possible if not probable.
The most dramatic suggestion regarding the creation of the Strait of Gibraltar has been offered by Terry Westerman(l), who has proposed that the rupturing of the landbridge was caused by two meteor impacts.
However, all that must be reconciled with the scientific findings of Kenneth Hsu who dated the last opening of the Gibraltar Strait to 5.5 million years ago(m).

Al-Idrisi (1100-1166), who’s full name was Abu Abd Allah Muhammad al-Idrisi al-Qurtubi al-Hasani al-Sabti and was a distinguished Arab scholar who collaborated with the eccentric King Roger II of Sicily in the 12th century, in the production of a scientifically founded map. Their project continued over a period of 15 years with the support of a team of geographers. The outcome was a map drawn on a silver disk nearly 2 metres in diameter accompanied by a book, generally known as Roger’s Book, which contained over 140 maps plus text.
What is interesting from the Atlantis point of view is that Roger’s Book recounts how the Gibraltar landbridge was breached by Alexander the Great. While the introduction of Alexander, who was very highly regarded by the Arabs, is obviously a folkloric embellishment, it demonstrates an underlying belief in the existence of such an isthmus in the distant past. Adding strength to this idea is that al-Idrisi was born in Ceuta on the African side of the Strait of Gibraltar and consequently would undoubtably have been fully aware of local traditions regarding a landbridge in ancient times.
Alexander Braghine[0156.140] recounts how Al-Idrisi refers to a very ancient cataclysm in Morocco during which the sea level rose eleven stadia (over 6500 feet), submerging cities and killing thousands. Unfortunately, we can only speculate on whether this is a description of a tsunami or the consequence of the breaching of a Gibraltar land bridge.
*Al-Idrisi recently had a feature, Al-Idrisi Montes, on the ‘dwarf’ planet Pluto, named after him by the International Astronomical Union.*
Al-Biruni (973-1048) is considered by many to have been one of the greatest scientists ever. He is credited with having developed elements of what we would now class as the modern ’scientific method’.
His interest in astronomy is reflected in the naming of a lunar crater after him. Six centuries before Galileo, al-Biruni was aware of the fact that the earth rotated on its axis daily and circled the sun once a year.
Al-Biruni recalls an ancient tale which speaks of brackish land extending from Egypt to Constantinople suggesting that at some time in the very distant past, but still within the experience of man, the Mediterranean dried out. This idea was reinforced by the comments of al-Mas’udi and in the 12th century by al-Idrisi in collaboration with King Roger II of Sicily who all quote ancient traditions that clearly support the concept of a Gibraltar dam that was probably breached as seal levels rose at the end of the last Ice Age.
