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 popularised 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 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 from east to west and over 3,000 miles from north to south, which is larger than South America.
