L. Sprague deCamp (1907-2000) is probably better known as a science fiction writer with over 120 books to his credit, including two non-fiction titles, Citadels of Mystery (First ed.: Ancient Ruins and Archaeology)  and Lost Continents , in which he was extremely sceptical of the reality of the Atlantis described by Plato. He offers the blunt declaration that Plato concocted the whole story, basing the tale on a mixture of the wealth of Tartessos in Spain, the destruction of the Greek island of Atalanta all intermingled with the mythology of Atlas. Although his criticism is harsh, it should be said that deCamp does display a reasonable degree of objectivity. It is probably because of his perceived integrity that other Atlantis sceptics continually trot out his views in support of their own position.
>A few years after Lost Continents was published, Nikolai Zhirov wrote a critique of the book(c), rejecting both its style and content. He notes that “the work shows a bad one-sided knowledge of geology and oceanography which is not counterbalanced by a critical examination of the published geological and oceanographical facts, although it is only by a study of these last that the Atlantis problem can be fully resolved.” Personally, I think that Zhirov’s comments are a reflection of his own bias towards an Atlantic location for Atlantis and ignore many other aspects of the Atlantis question, such as the date when Atlantis existed, as well as the identity of the Atlanteans.<
One of deCamp’s most quoted extracts is that “you cannot change all the details of Plato’s story and still claim to have Plato’s story.” While I fully endorse this comment, I must point out that there is a difference between changing and interpreting. For example when Plato refers to Asia or Libya, even deCamp accepted that in Plato’s day ‘Asia’ was not the landmass we know, stretching from the Urals to Japan, but a much smaller territory [0194.27]. In fact the term ‘Asia’ at one point was just applied to a small region of modern Turkey. Similarly, ‘Libya’ was not the country we know by that name today, but the term was often employed to designate all of North Africa west of Egypt. There are a number of other details in Plato’s narrative that require explanation or interpretation and so as long as any such elucidation is based on evidence and reason they cannot be glibly dismissed as substantive ‘changes’.
He scathingly refutes the more outlandish Atlantis theories that have deviated dramatically from Plato’s narrative, commenting that without matching the “date, location, size and island character” with the text we do not have Atlantis.
DeCamp also considered Alfred Wegner’s theory of continental drift as “very doubtful”, but corrected this statement in a 1970 edition of his book. Immanuel Velikovsky also received the sharp end of deCamp’s pen, describing his catastrophic theories as ‘mad’. Further information on deCamp can be found on the internet(a) where excerpts from his Lost Continents are also available(b).
Henry Eichner drew attention  to the fact that in three books relating to Atlantis authored by deCamp he describes a ring found by Adolf Schulten at the site of Tartessos, but slightly differently in all three! In Lost Continents it is plain, in Lands Beyond it is copper, while in Ancient Ruins and Archaeology it became gold!
Frank Joseph incorrectly claimed in the July/August 2011 issue of AtlantisRising magazine that DeCamp “formerly a staunch disbeliever in Atlantis, was later convinced it did indeed exist in south-coastal Iberia.”

Johannes Goropius Becanus (1519-1572) was a Dutch physician and linguist, although he was of the opinion that the Dutch language had been used in the Garden of Eden and was the mother of all other languages(c) ! We hope his knowledge of medicine was better than his linguistics. He was also one of the first to propose the Doñana Marshes of Andalusia as the site of Atlantis(a)(b). This can be found in the Hispanica section of his Opera published posthumously in 1580.
The Balearic Islands in the Western Mediterranean were not occupied until around 2200 BC. Although the two larger islands of Majorca and Minorca have many megalithic monuments, principally taulas and talayots, they have not, so far, been part of any Atlantis location theory. The only mention that I can find is the unsubstantiated claim by Frank Joseph[0104.66] that the early settlers were invaders from Atlantis.
*Steven Sora noted(d) that “From the Bible we know the Tartessians were ruled by kings and mentioned with princes of the isles—very likely islands like Corsica and the Balearics.” I mention this as Tartessos is frequently linked with Atlantis.*
The island of Es Vedra off the west coast of Ibiza, the third largest of the Balearics, has had a number of imaginative myths, old and new, associated with it, including that it is supposed to be the birthplace of the goddess Tanit and the limestone on the island is alleged to have been used to build the Egyptian Pyramids. Then, for good measure, Es Vedra is also claimed to be a peak of the mountains of Atlantis!(c)
In 1911, Albert Gruhn proposed that Atlantis may have lain between the Balearics and Sardinia(a), while a century later the American nuclear engineer, Robert J. Tuttle, suggested[1148.301] the Balearics as a possible location when sea levels were lower and the archipelago was more extensive,*explaining that “For Atlantis, we must relocate the ‘Pillars of Herakles’ to somewhere between Tunisia (the Roman ‘Africa’), Sicily and the toe of Italy”*
The most recent discovery of a prehistoric stone structure on Menorca was reported in the Spring 2016 edition of Popular Archaeology magazine(b).

Mario Cabriolu is a Sardinian, who actively supports the theory of Sergio Frau, which places Atlantis on Sardinia. He has published an illustrated paper on the sardolog.com website in support of that contention(a) with the bold title of Sardinia is Atlantis? He also wrote papers on Cerne(b) and Tartessos(c) on the same site.

Javier Recuenco Andrés (1973- ) is an IT engineer from Cadiz in Spain. He has a passion for chess, history and mythology. His interest in the latter has led to his publication of a heavily illustrated The Historical Reality of Atlantis in Spanish and English (Kindle only).
He begins with an in-depth examination of a ‘Tartessian’ gold disk that led on to an etymological investigation of the ‘K-N’ inscription on it, which he believes referred to the Conii people who settled in what is now southern Portugal. He speculates that the design of the disk reflects the layout of the acropolis of Atlantis! He has suggested that this acropolis was probably located in the vicinity of the Canary Islands.
In 2013, Recuenco Andrés and Diaz-Montexano jointly published a paper(a) on the academia.edu website offering comparable interpretations of the disk with the same conclusion that it was connected with Atlantis.
Javier dates the foundation of Atlantis to a period between 21,000 and 12,000 BC. Andrés has a hyperdiffusionist view of Atlantis showing rock carvings in North Africa, America, Australia, China and of course his native Iberia as evidence for their global influence. The fall of the Atlantean ‘Empire’ he suggests was between 12,000 and 9,000 BC, as the last Ice Age was ending.
He subscribes to the idea that there was a Gibraltar landbridge, which was breached around 5,500 BC that eventually led to the linking of the Mediterranean and the Black Sea, an event originally revealed by Ryan & Pitman.
Javier also believes that Egypt was occupied by Atlanteans from 7000–5500 BC, but that their influence led to the building of the pyramids! In fact, he attributes the pyramids of China and America to Atlantean influence. He identifies Knossos in Crete as an Atlantean colony in the eastern Mediterranean.
In my opinion, Javier has produced an original work, unlike the regurgitated offerings of so many others. Nevertheless, I think his work has too many assumptions based on excusable subjectivity.
Louis Millette, is a Canadian commentator who claims to have identified the location of Atlantis in the region of the Guadalquivir River in Spain’s Andalusia, maintaining that Tartessos, Tarshish and Atlantis were all the same. He has posted a set of three satellite image(d) to support his contention, unfortunately, I cannot see anything that might be related to Atlantis. His brief video clip(e) is equally uninformative.
However, Millette is a firm believer in extraterrestrial visitors(a), which for me is sufficient reason to consider him an unreliable researcher. He also claims to have located the ‘Hanging Gardens of Babylon’ in Nineveh, an idea already proposed by Stephanie Dailey of Oxford University as early as 1992(c). Even more provocative is the suggestion from Constantinos Ragazas that the correct title should be The Hanging Gardens of Göbekli Tepe!(f)
Millette promises startling revelations regarding Stonehenge in June 2015. However, a brief posting(g) on the academia.edu website, consisting of some text and three images reveals nothing!

Huelva is a city in southwest Spain that has frequently featured in the search for Tartessos. Adolph Schulten(a) as well as Jorge Bonsor devoted years to studying Huelva, Cádiz and Seville in their search for the legendary city. Even if Tartessos is conclusively identified, it is still a long way from proving it to be Plato’s Atlantis, which after all is supposed to be submerged. I was recently offered satellite images that purported to show traces of ground features that ‘might’ indicate ancient ruins with a remote possibility that they might be part of Tartessos!

Ephorus (c.400-330) was a respected Greek historian from Cyme (ancient Phriconis) in northwest Turkey. He told us that the capital of Tartessos was two day’s travel from the Pillars of Heracles and more importantly that a Tartessos continued as a trading centre, dealing in metals, as late as the 4th century BC, which is after Solon’s visit to Egypt. Since Atlantis was submerged hundreds if not thousands of years before Solon lived, the Tartessos referred to by Ephorus cannot be Atlantis!
Ephorus is also the name of anti-plagiarism software.
Lereno Barradas was a Portuguese writer who speculated in the early 1970’s that Tartessos could be identified with Atlantis and had been located in the Tagus estuary near the site of modern Lisbon. He also suggested that these
ancient Atlanteans had travelled to America.
