Ronan Coghlan (1948- ) was born in Dublin and now lives in Bangor, Northern Ireland. He has been a teacher at a number of schools and has published books on a variety of subjects ranging from Fairies to King Arthur to Atlantis. His best-selling Illustrated Encyclopedia of Arthurian Legends is reported to have sold 120,000 copies!
Coghlan has also produced a Companion to Atlantis and Other Mystery Lands, which is an A-Z guide to Plato’s island as well as the more contentious Mu and Lemuria. My principal objection to this work is the inclusion of too many references to the ramblings of so many self-proclaimed psychics, obvious psychotics and downright fraudsters. It would be nitpicking to go any further but on the positive side I found this book more informative than the A-Z Guide published by Simon Cox and free of the ancient America bias of Frank Joseph’s offering. .
Nigel Appleby (a.k.a. Major Niall Arden) is the ‘author’ of Hall of the Gods, which purported to identify the location, in Egypt, of the Hall of Records that is supposed to contain the accumulated knowledge of an advanced worldwide civilisation that preceded the ancient Egyptians.
The author wrote of ‘Atlantis’ being “really just a symbolic name for the previous worldwide civilisation that existed prior to the last reversal of the Sun and Earth’s magnetic fields and the subsequent cataclysm that followed.” He then added that most of this civilisation still exists, virtually intact, beneath the Antarctic ice (p.363). He also claimed to have identified Nibiru in Sumerian texts independently of Zechariah Sitchin and to have deduced that it is “about the size of Earth and nearer than anticipated.”
He also announced the establishment of ‘Operation Hermes’, which had the objective of locating the Hall of Records near Giza(c) as well as other expeditions to Central & South America, China and Antarctica (p.378). Operation Hermes was abandoned when the Egyptian authorities refused permission for the expedition.
Shortly after the publication of the book in 1998, the publishers had to withdraw it from sale following claims of plagiarism by a number of other authors(a). Lynn Picknett & Clive Prince reveal some of the details of this episode in their Stargate Conspiracy [705.97].>Ian Lawton & Chris Ogilvie-Herald also devote a chapter of Giza the Truth  to ‘The Appley Affair’ giving more detail, particularly the battle that Ralph Ellis had to demonstrate that large chunks of his book, Thoth: Architect of the Universe, had been used by Appleby.<
The whole matter was further confused when Graham Hancock and Robert Bauval along with Colin Wilson, Andrew Collins, Christopher Knight, Robert Lomas, Simon Cox and Alan Alford issued An Official Statement Regarding Operation Hermes(a) declaring that they were unaffiliated with Operation Hermes, then and in the future.
Lightning struck twice when the second book of Appleby’s, Desert Fire, was also withdrawn from sale within days of publication in 2006!
Simon Cox (1966- ) was a former editor-in-chief of Phenomena magazine, which is dedicated to promoting alternatives to accepted historical orthodoxies. He currently runs the UK publishing company Henu Publications. Cox has also worked as a researcher for well-known writers such as Graham Hancock and David Rohl. He is probably better known as the author of a number of books that investigate the historical realities behind the works of Dan Brown[247-250]. He is co-author of an A-Z series[251-254] of books on subjects such as Ancient Egypt, King Arthur and Atlantis.
Unfortunately, Cox’s Atlantis offering is just a heavily padded rehash of well known material and includes a number of headings that at the most generous could only be described as having a very tenuous connection with Atlantis; they include Dogon Tribe, Easter Island and 20,000 Leagues Under the Sea.The headings range from ‘Aelian’ to ‘Twenty Thousand Leagues Under the Sea’, so really the title should be an A to T of Atlantis.
The dustcover notes, for which I’m assuming that neither Cox nor his co-author Mark Foster were responsible, claim that the book answers the question of where Atlantis was located. It does not.
A decade ago Cox launched the Into the Duat website(a).
Mark James Foster runs a small London design agency(a) and is also an historical researcher who had an interesting website that is principally concerned with ancient Egypt. His first book was as co-author with Simon Cox on an A–Z of Atlantis. This small volume offers nothing new and is just a re-working of well-known material. Foster has also worked with Ralph Ellis on a number of articles(c).
*W.M. Flinders Petrie (1853-1942) investigated what he described as ‘trial passages’ near Giza’s Great Pyramid. Foster has written an extensive article on them and in November 2017 he updated this article(d) in the light of the claimed discovery of previously unknown voids in the GP.*
