Mu

Mu (claimed to be derived from the Ancient Egyptian T-Mu, Mayan Ti-Mu) is the name of a proposed lost island (or continent), first advanced by Augustus Le Plongeon, who held it to be the same land as Atlantis, based on his personal translations of Mayan glyphs, which he found described a "country situated in the basin of the Atlantic ocean [that] was reduced to ashes."

The concept of Mu was later re-developed at great length by James Churchward in a series of books, beginning with The Lost Continent of Mu: the Motherland of Man (1926), in which he set forward the argument that the continent existed formerly in the Pacific Ocean, and was home to a peoples called the Naacal. The resituating of Mu to the Pacific caused it to be conflated with Lemuria by later adherents, and today the two are often used interchangeably by believers.
