Atlantis is a fictional island mentioned in Plato's works Timaeus and Critias as part of an allegory on the hubris of nations. In the story, Atlantis is described as a naval empire that ruled all Western parts of the known world, making it the literary counter-image of the Achaemenid Empire. After an ill-fated attempt to conquer "Ancient Athens," Atlantis falls out of favor with the deities and submerges into the Atlantic Ocean. Since Plato describes Athens as resembling his ideal state in the Republic, the Atlantis story is meant to bear witness to the superiority of his concept of a state.
Lyonesse is a kingdom which, according to legend, consisted of a long strand of land stretching from Land's End at the southwestern tip of Cornwall, England, to what is now the Isles of Scilly in the Celtic Sea portion of the Atlantic Ocean. It was considered lost after being swallowed by the ocean in a single night. The people of Lyonesse were said to live in fair towns, with over 140 churches, and work in fertile, low-lying plains. Lyonesse's most significant attraction was a castle-like cathedral that was presumably built on top of what is now the Seven Stones Reef between Land's End and the Isles of Scilly, some 18 miles (29 km) west of Land's End and 8 miles (13 km) north-east of the Isles of Scilly.
Mu is a lost continent introduced by Augustus Le Plongeon (1825–1908), who identified the "Land of Mu" with Atlantis. The name was subsequently identified with the hypothetical land of Lemuria by James Churchward (1851–1936), who asserted that it was located in the Pacific Ocean before its destruction. The place of Mu in both pseudoscience and fantasy fiction is discussed in detail in Lost Continents by L. Sprague de Camp.
Lemuria, or Limuria, was a continent proposed in 1864 by zoologist Philip Sclater, theorized to have sunk beneath the Indian Ocean, later appropriated by occultists in supposed accounts of human origins. The theory was discredited with the discovery of plate tectonics and continental drift in the 20th century.
The Lyonesse Trilogy is a group of three fantasy novels by Jack Vance, set in the European Dark Ages, in the mythical Elder Isles west of France and southwest of Britain, a generation or two before the birth of King Arthur. The stories contain references to Atlantis and Arthurian mythology, particularly to the mythical country of Lyonesse. They are told in several related storylines which are not always strictly chronological.
The three Storegga Slides are amongst the largest known submarine landslides. They occurred at the edge of Norway's continental shelf in the Norwegian Sea, approximately 6225–6170 BCE. The collapse involved an estimated 290 km (180 mi) length of coastal shelf, with a total volume of 3,500 km3 (840 cu mi) of debris, which caused a paleotsunami in the North Atlantic Ocean.
Kumari Kandam is a mythical continent, believed to be lost with an ancient Tamil civilization, supposedly located south of present-day India in the Indian Ocean. Alternative names and spellings include Kumarikkandam and Kumari Nadu.
Root races are concepts in the esoteric cosmology of Theosophy. As described in Helena Petrovna Blavatsky's book The Secret Doctrine (1888), these races correspond to stages of human evolution, and existed mainly on now-lost continents. Blavatsky's model was developed by later theosophists, most notably William Scott-Elliot in The Story of Atlantis (1896) and The Lost Lemuria (1904). Annie Besant further developed the model in Man: Whence, How and Whither (1913). Both Besant and Scott-Elliot relied on information from Charles Webster Leadbeater obtained by "astral clairvoyance". Further elaboration was provided by Rudolf Steiner in Atlantis and Lemuria (1904). Rudolf Steiner, and subsequent theosophist authors, have called the time periods associated with these races Epochs.
Kitezh is a legendary and mythical city beneath the waters of Lake Svetloyar in the Voskresensky District of the Nizhny Novgorod Oblast in central Russia. Reference to Kitezh appears for the first time in Kitezh Chronicle, an anonymous book from the late 18th century, believed to have originated among the Old Believers.
There are several hypotheses about real-world events that could have inspired Plato's fictional story of Atlantis, told in the Timaeus and Critias. While Plato's story was not part of the Greek mythic tradition and his dialogues use it solely as an allegory about hubris, researchers have speculated about real natural disasters that could have served as inspiration. Additionally, many works of pseudohistory and pseudoarchaeology treat the story as fact, offering reinterpretations which tie to national mysticism or theories of ancient aliens. While Plato's story explicitly locates Atlantis in the Atlantic Ocean beyond the Pillars of Hercules, location hypotheses include Helike, Thera, Troy, and the North Pole.
The legendary island of Atlantis has often been depicted in literature, television shows, films and works of popular culture.
Atlantis: The Lost Continent Revealed is a pseudohistorical book by Charles Berlitz. He lists several alternative theories on where the possible mythical Atlantis may have been situated, and cites different legends and stories that may support the different theories. All areas and theories are covered starting with Plato, Crete (Thera), Azores and Edgar Cayce's involvement in the story.
Cantre'r Gwaelod, also known as Cantref Gwaelod or Cantref y Gwaelod, is a legendary ancient sunken kingdom said to have occupied a tract of fertile land lying between Ramsey Island and Bardsey Island in what is now Cardigan Bay to the west of Wales. It has been described as a "Welsh Atlantis" and has featured in folklore, literature, and song.
Doggerland was an area of land in Northern Europe, now submerged beneath the North Sea, that connected Britain to continental Europe. It was repeatedly exposed at various times during the Pleistocene epoch due to the lowering of sea levels during glacial periods. It was last flooded by rising sea levels around 6500–6200 BCE. The flooded land is known as the Dogger Littoral. Geological surveys have suggested that it stretched from what is now the east coast of Great Britain to what is now the Netherlands, the western coast of Germany and the Danish peninsula of Jutland. It was probably a rich habitat with human habitation in the Mesolithic period, although rising sea levels gradually reduced it to low-lying islands before its final submergence, possibly following a tsunami caused by the Storegga Slide. Doggerland was named after the Dogger Bank, which in turn was named after 17th-century Dutch fishing boats called doggers.
Cornish mythology is the folk tradition and mythology of the Cornish people. It consists partly of folk traditions developed in Cornwall and partly of traditions developed by Britons elsewhere before the end of the first millennium, often shared with those of the Breton and Welsh peoples. Some of this contains remnants of the mythology of pre-Christian Britain.
Zealandia, also known as Te Riu-a-Māui (Māori) or Tasmantis, is an almost entirely submerged mass of continental crust in Oceania that subsided after breaking away from Gondwana 83–79 million years ago. It has been described variously as a submerged continent, continental fragment, and microcontinent. The name and concept for Zealandia was proposed by Bruce Luyendyk in 1995, and satellite imagery shows it to be almost the size of Australia. A 2021 study suggests Zealandia is over a billion years old, about twice as old as geologists previously thought.
A continent is any of several large geographical regions. Continents are generally identified by convention rather than any strict criteria. A continent could be a single landmass or a part of a very large landmass, as in the case of Asia or Europe. Due to this, the number of continents varies; up to seven or as few as four geographical regions are commonly regarded as continents. Most English-speaking countries recognize seven regions as continents. In order from largest to smallest in area, these seven regions are Asia, Africa, North America, South America, Antarctica, Europe, and Australia. Different variations with fewer continents merge some of these regions; examples of this are merging North America and South America into America, Asia and Europe into Eurasia, and Africa, Asia, and Europe into Afro-Eurasia.
A submerged continent or a sunken continent is a region of continental crust, extensive in size but mainly undersea. The terminology is used by some paleogeologists and geographers in reference to some landmasses.
Forgotten continent may refer to:
Greater Adria was a paleomicrocontinent that existed from 240 to 140 million years ago. It is named after Adria, a geologic region found in Italy, where evidence of the microcontinental fragment was first observed. Greater Adria's size can be compared to that of modern day Greenland.
