Ireland according to James Bramwell [0195.181], was first identified with Atlantis as early as circa 1250 AD in the Speculum Regale (The King’s Mirror)(g) which was written in Norway. Apart from that, Ireland was less controversially was first suggested in the 18th century as a possible location of Atlantis by the English geologist John Whitehurst. The idea lay dormant for over a century until the early part of the 20th century when George H. Cooper  suggested that Cork harbour fits Plato’s description of the harbour of Atlantis. Fifty years later an official guidebook claimed that one of the outposts of Atlantis was to be found on the west coast of Galway. As a nation famed for its storytelling we have never let truth stand in the way of a good tale.
The mythical Hy-Brasil was shown west of Ireland on maps as early as 1325 and incredibly, was not removed from naval charts until 1865. The UK’s Daily Star (21/5/16) with typical tabloid accuracy told its readers(f) that Hy-Brasil was off the coast of ‘Britain’!
In 1976, Steiner Books, New York, republished a book under the misleading title of Atlantis in Ireland. One may be excused for viewing this as a blatant case of exploitative opportunistic publishing. The original text was written by Henry O’Brien and published in London (1834) as The Round Towers of Ireland. Apart from being written in the rather turgid English of the period, there is not a single reference to Plato or Atlantis to be found in that volume.
Diodorus Siculus, in a well-known passage (Bk 1.158), that is claimed by some as a reference to Ireland(h), describes it as ”an island in the ocean over against Gaul, to the north, and not inferior in size to Sicily, the soil of which is so fruitful that they mow there twice in the year.” Some consider this to be reminiscent of the Platonic reference to the two crops a year gathered in Atlantis. However, I am more inclined to think that Diodorus was referring to Britain. Diodorus also mentions the Irish singular temples of ’round form’, however, this seems too early to be a reference to the round towers and more likely to be an allusion to the astronomically aligned mounds such as Newgrange, Dowth and Knowth in Ireland or Stonehenge in Britain!
Bob Quinn has written and lectured on possible ancient cultural links between North Africa and Ireland. This idea may have been reinforced by a number of 19th century reports that visitors from North Africa were able to understand the Irish language!(i)
In 1923, Conor MacDari, who’s eccentricity was comparable with that of Comyns Beaumont, published Irish Wisdom Preserved in the Bible and Pyramids , which among a litany of bizarre claims, proposed that Atlantis had been located in Ireland.
When Ignatius Donnelly came to the subject of Ireland, he attributed an Atlantean origin to so the various waves of settlers that came to the post-glacial island. He substitutes evidence with assertion and speculation. Donnelly further claimed that the famous round towers of Ireland are proof that the people of Atlantis settled in Ireland.
More recently Ulf Erlingsson, a Swedish geographer, insisted that with a claimed probability
factor of 99.98%, that his interpretation of Plato’s text demonstrates that Ireland was home to Atlantis . The subtitle of the book, Mapping the Fairy Land, is probably a good guide on how seriously to take this book, particularly as it is by an author who hails from the land of the original Trolls.
In March 2008, it was reported that a Dr. Jac Hummer had mounted an expedition to South America with the intention of discovering the remains of St. Patrick under a pyramid there. But it gets better – he then explains that such a discovery will prove his theory that Ireland is Plato’s lost island of Atlantis!I can only conclude that this is a hoax story.
Irish legend speaks of the Domnu, people of the deep sea from a land that disappeared beneath the waves. However, Ireland is still above the waves and in contrast to Plato’s statement that even in his time the location of Atlantis was marked by impassable shallows. Since sea levels have generally risen only slightly since Plato lived, he cannot have been referring to Ireland.
John Douglas Singer in his slender book, Ireland’s Mysterious Lands and Sunken Cities , has carried out an investigation into the ancient legends of Ireland and their possible connection with Plato’s Atlantis. He points out that Ireland has the greatest number of legends relating to sunken cities and islands! He draws on the works of Egerton Sykes and Lewis Spence among others.
Ireland was also nominated by Thomas Dietrich as an early colony of Atlantis in The Origin of Culture.
Somewhat incongruously, the website of extremist, Dejan Lucic, has an extensive and fully referenced article entitled The Irish Origins of Civilisation(a), including not a few controversial sources such as, Comyns Beaumont, Ralph Ellis and John Gordon.
Around 2010, a father and son team Francis J.Ward & Francis P.Ward seeminglly published their first book The Truth Against the World-Red Phoenix Rising & the Return of the Thunder Gods , in which they express the view that “Atlantis was a global, maritime empire based in Ireland”.(c)
In 2013, Skender Hushi informed the world that Albanian had been the original language of Ireland and Atlantis! Another equally odd claim came from Zoltán Simon who proposed that the ancient Hun Calendar came from Ireland [0549.147]!
Evidence for the earliest humans in Ireland is now dated as 10,500 BC.(d)(e)
In July 2020, Erlingsson’s Atlantis in Ireland theory was recycled by a website(j) with the title of ‘Keystone University’. It promises to build a world-class enterprise centre in Ireland in 2025. The site implies that Keystone has the support of Brian Tracy, an American self-development speaker. While Keystone seems to focus on business success and personal development, it incongruously includes a study of Atlantis a la Erlingsson as part of its course! It has published two papers on the Ancient Origins website(k)(l).
The Atlantis claims of Keystone were found earlier in January on YouTube and while it ostensibly appeared to add the gravitas of an educational institution to the subject of Atlantis, it was only a smokescreen for an attempt to entice people to sign up for overpriced seminars. Jason Colavito drew attention(m) to this at the time and to the more recent articles on Ancient Origins(n).
Rockall is an uninhabited islet in the North Atlantic, northwest of Donegal in Ireland. It appears to have been first marked on a map in 1640(c). It is first mentioned in literature in 1716 and referred to by locals as Rocabarraigh, which is also the name of “a mythical rock which is supposed to appear three times, the last being at the end of the world.”(m).
This ostensibly insignificant piece of stone is around 80ft by 100ft at the base and approximately
70ft in height. Nevertheless, its ownership is disputed by Ireland, Iceland, the Faroe Islands and the United Kingdom.
Rocabarraidh which was a mythic island referred to in the folklore of the Lordship of the Isles, a Scottish title, is generally accepted to be an early allusion to Rockall. The Atlantic rock is considered as part of the Hebridean parish of South Harris.
In June 1997, Greenpeace declared Rockall to be the independent state of Waveland(f).
Recently, a new claim has been made in connection with Rockall, namely, that it is a remnant of the Atlantis highlands, with the plain so vividly described by Plato, now situated under the sea to the southwest of the rock. Two extensively illustrated French websites(a)(b) expound this theory. Which, however, are somewhat less than convincing. However, a 1938 newspaper report(d) suggests that a proposed linkage with Atlantis goes back much further!
In December 2016, Jonathan Northcote published 16.484ºW 58.521ºN, Atlantis, Found?, in which he offers spirited support for this location using a mass of geological data and underwater topography. He also suggests that Gades may have been Ireland. In January 2019, Northcote revised his book with additional material and published this second edition with the title of Atlantis, Found? An investigation into ancient accounts, bathymetry and climatology .
Stuart L. Harris, the prolific American researcher, has, in recent private correspondence with me, supported the vicinity of Rockall as the location of Atlantis, dating its demise to around 9577 BC. He later expanded on this in a highly speculative paper published on the Academia.edu website.
At the end of September 2018, the UK’s Daily Star, a well-known comic for adults, tried to revive the idea of Atlantis in Frisland(g). They based their brief article on the speculations of Matt Sibson, presented as an ‘expert’, who admits that “there are still some questions that need clearing up.” I would like to know why Frislanders in the middle of the last Ice Age would want to attack a non-existent Athens 4,000 km away. If Sibson is considered to be an expert historian, my cat is a brain surgeon. Jason Colavito had a few words to add regarding Sibson’s pathetic claims(h).
Incredibly, a week later the same ‘newspaper’ cited Sibson again, this time claiming that Rockall was the remains of Atlantis(i), an equally silly idea that is not new. The UK’s online Express recycled this nonsense in January 2020(k).
Kevin A. & Patrick J. Casey have published a series of papers on the Academia.edu website outlining a globally catastrophic event that occurred thirteen thousand years ago, which they refer to as the ’13K Event’, but is more popularly known as the onset of the Younger Dryas period. In February 2019, they published Atlantis Revisited (j), in which they claim that Rockall was the location of Atlantis.
Less extreme is a claim by John Esse Larsen that in support of the theory that Homer’s Odyssey refers to adventures in the North Atlantic he suggests that Rockall is referenced in Odyssey 10.513(l).
