Mu is a legendary lost continent that also appears in lost world literature.

It is a term introduced by Augustus Le Plongeon, who used the “Land of Mu” as an alternative name for Atlantis.

It was subsequently popularized as an alternative term for the hypothetical land of Lemuria by James Churchward, who asserted that Mu was located in the Pacific Ocean before its destruction.

Archaeologists assign assertions about Mu to the category of pseudoarchaeology. The place of Mu in literature has been discussed in detail in Lost Continents (1954) by L. Sprague de Camp.

Geologists dismiss the existence of Mu and the lost continent of Atlantis as physically impossible, arguing that a continent can neither sink nor be destroyed in the short period of time asserted in legends and folklore and literature about these places. Mu’s existence is considered to have no factual basis.

History of the concept

Augustus Le Plongeon

The mythical idea of the “Land of Mu” first appeared in the works of Augustus Le Plongeon (1825–1908), after his investigations of the Maya ruins in Yucatán.

He claimed that he had translated the first copies of the Popol Vuh, the sacred book of the K’iche’ from the ancient Mayan using Spanish. Yucatán was older than those of Greece and Egypt and told the story of an even older continent.

Le Plongeon got the name “Mu” from Charles Étienne Brasseur de Bourbourg, who in 1864 mistranslated what was then called the Troano Codex (now called “Madrid Codex”) using the de Landa alphabet.

Brasseur believed that a word which he read as Mu referred to a land that had been submerged by a catastrophe. Le Plongeon identified this lost land with Atlantis and, following Ignatius Donnelly in Atlantis: The Antediluvian World (1882), identified it as a continent that had once existed in the Atlantic Ocean:

In our journey westward across the Atlantic we shall pass in sight of that spot where once existed the pride and life of the ocean, the Land of Mu, which, at the epoch that we have been considering, had not yet been visited by the wrath of Human, that lord of volcanic fires to whose fury it afterward fell a victim. The description of that land given to Solon by Sonchis, priest at Sais; its destruction by earthquakes, and submergence, recorded by Plato in his Timaeus, have been told and retold so many times that it is useless to encumber these pages with a repetition of it.

Le Plongeon claimed that the civilization of ancient Egypt was founded by Queen Moo, a refugee from the land’s demise. Other refugees supposedly fled to Central America and became the Maya.

James Churchward

Mu, as an alternative name for a lost Pacific Ocean continent previously identified as the hypothetical Lemuria (the supposed place of origin for lemurs), was later popularized by James Churchward (1851–1936) in a series of books, beginning with Lost Continent of Mu, the Motherland of Man (1926), re-edited later as The Lost Continent Mu (1931). Other popular books in the series are The Children of Mu (1931), and The Sacred Symbols of Mu (1933).

Churchward claimed that “more than fifty years ago“, while he was a soldier in India, he befriended a high-ranking temple priest who showed him a set of ancient “sunburnt” clay tablets, supposedly in a long lost “Naga-Maya language” which only two other people in India could read.

Churchward convinced the priest to teach him the dead language and decipher the tablets by promising to restore and store the tablets for Churchward was an expert in preserving ancient artifacts. The tablets were written in either Burma or in the lost continent of Mu itself according to the high priest.

Having mastered the language himself, Churchward found out that they originated from “the place where [man] first appeared—Mu“. The 1931 edition states that “all matter of science in this work are based on translations of two sets of ancient tablets“: the clay tablets he read in India, and a collection of 2,500 stone tablets that had been uncovered by William Niven in Mexico.

The tablets begin with the creation of Earth, Mu, and the superior human civilization Naacal by the seven commands of the seven superlative intellects of the Seven-headed serpent Narayana. This creation story dismisses the theory of evolution.

Churchward gave a vivid description of Mu as the home of an advanced civilization, the Naacal, which flourished between 50,000 and 12,000 years ago, was dominated by a “white race” and was “superior in many respects to our own“.

Churchward research supports a quasi-Christian belief system and white supremacy denounced science and evolution. His image of a perfect human is the white version of Jesus Christ. At the time of its demise, about 12,000 years ago, Mu had 64,000,000 inhabitants and seven major cities, and colonies on the other continents. The 64 million inhabitants were separated as ten tribes that followed one government and one religion.

Churchward claimed that the landmass of Mu was located in the Pacific Ocean, and stretched east-west from the Marianas to Easter Island, and north-south from Hawaii to Mangaia.

According to Churchward, the continent was supposedly 5,000 miles east to west and over 3,000 miles from north to south. That is bigger than the continent South America. The continent was believed to be flat with massive plains, vast rivers, rolling hills, large bays, and estuaries.

He claimed that according to the creation myth he read in the Indian tablets, Mu had been lifted above sea level by the expansion of underground volcanic gases. Eventually Mu “was completely obliterated in almost a single night”: after a series of earthquakes and volcanic eruptions, “the broken land fell into that great abyss of fire” and was covered by “fifty millions of square miles of water.”

Churchward claims the reasoning for the continent’s destruction in one night was because the main mineral on the island was granite and was honeycombed to create huge shallow chambers and cavities filled with highly explosive gases. Once the gases were empty after the explosion they collapsed on themselves causing the island to crumble and sink.

Churchward claimed that Mu was the common origin of the great civilizations of Egypt, Greece, Central America, India, Burma and others, including Easter Island, and was, in particular, the source of ancient megalithic architecture. As evidence for his claims, he pointed to symbols from throughout the world, in which he saw common themes of birds, the relation of the Earth and the sky, and especially the Sun.

Churchward claims that the king of Mu was named Ra and he relates this to the Egyptian god of the sun, Ra, and the Rapa Nui word for Sun, ra’a. He claimed to have found symbols of the Sun in “Egypt, Babylonia, Peru, and all ancient lands and countries – it was a universal symbol.

Other pieces of evidence for his claims, Churchward looked to the Holy Bible and found that through his own translations, Moses was trained by Naacal Brotherhood in Egypt. Assyria mistranslated when writing and misplaced the garden of Eden, which according to Churchward would have been located in the Pacific ocean.

Churchward makes references to the Ramayana epic, a religious text of Hindu attributed to sage and historian Valmiki. Valmiki mentions the Naacals as “coming to Burma from the land of their birth in the East,” that is, in the direction of the Pacific Ocean.

Churchward also looked into legends of the Native American tribe, Pueblo, legend says that four fathers sailed from where the sun sets which fits Churchward’s location of Mu. Churchward translated Yucatan ruins that tell of an original land to the west.

He claims the ancient Mexican pyramids are monuments to the destruction of the land to the west. Churchward’s other pieces of evidence to his claims lie within the south pacific islands. Cook island has stone monuments but has no quarry so it is presumed that they were brought there from Mu as Churchward believes.

Topgona island has no stone just coral but has a massive stone arch, the continent of Mu would’ve been near this island. Marshall islands have tall slender pyramids that had orientations used by the natives them not knowing how they got them. Several south sea islands contain great ruins of a temple which on the walls contain sacred symbols of Mu.

The lost continent of Mu according to Jack E. Churchward is different from the continent of Lemuria that is theorized to be in the Pacific or the Indian Ocean.

In his novels, Churchward never mentions the supposed other lost continent of Lemuria. Lemuria is imagined to be slightly bigger than Mu when located in the Pacific, but otherwise, most people generally consider them the same mythological continent that once existed in the Pacific Ocean.

John Newbrough

In the 1882 novel Oahspe: A New Bible, John Newbrough included a map of the Earth in antediluvian times (before the great flood in biblical times) where an unknown continent is located in the Northern Pacific.

Newbrough called this continent Pan. People often link both Pan and Mu as the same mythological continent since both are claimed to be located in the Pacific. Newbrough continues to claim that the unknown continent disappeared 24,000 years ago, but will soon rise from the Pacific and will be inhabited by the Kosmon race.

Max Heindel

Max Heindel, a Danish-American occultist, wrote about Mu in The Rosicrucian Cosmo-Conception (1909), which offers a different image and chronology.

According to Heindel, Mu existed when the Earth’s crust was still hardening, in a period of high heat and dense atmosphere. Heindel claims humans existed at this time, but humans had the power to shape-shift.

He says they had no eyes but rather two sensitive spots that were affected by the light of the Sun. In the dense atmosphere, humans were guided more by internal perception than by external vision. The language of these humans consisted of the sounds of nature.

Louis Jacolliot

Louis Jacolliot was a French attorney, judge, and occultist who specialized in the translation of Sanskrit. He wrote about the land of the Rutas, a lost land that ancient sources claimed was in the Indian Ocean but which he placed in the Pacific Ocean and associated with Atlantis stories in Histoire des Vierges.

Les Peuples et les continents disparus (1874). He amplified upon this in Occult Science in India (1875, English translation 1884). He has been identified as a contributor to Rosicrucianism.

Modern claims

James Bramwell and William Scott-Elliot claimed that the cataclysmic events on Mu began 800,000 years ago and went on until the last catastrophe, which occurred in precisely 9564 BC.

In the 1930s, Atatürk, founder of the Turkish Republic, was interested in Churchward’s work and considered Mu as a possible location of the original homeland of the Turks.

Masaaki Kimura has suggested that certain underwater features located off the coast of Yonaguni Island, Japan (popularly known as the Yonaguni Monument), are ruins of Mu. (or “ruins of the lost world of Muin” according to CNN).
