Le Plongeon, Augustus
French physician (1826 to 1908) who lived for many years among the Lacadone Indians, descendants of the Mayas, learning their language, customs, and oral traditions firsthand. Dr. Le Plongeon was first to excavate the pre-Columbian ruins of Yucatan, amassing important artifact collections that became valuable additions to some of the leading museums of Mexico and the United States. He was also an early pioneer in decipherment of the Mayan hieroglyphs, which his academic contemporaries found utterly inscrutable.

It was his ability to achieve at least their partial translation with the help of his Lacadone friends that sabotaged his professional standing, because Le Plongeon found references among a few of the carved stelae to the sunken civilization of Mu. After its destruction, survivors arrived in Central America, he read, where they became the ancestors of the Mayas.

He believed the story was preserved in the Tro-Cortesianus, or Troano Codex, one of only three books that survived the wholesale incineration of Mayan literature by Christian zealots in the 16th century. While his literal translation was erroneous, it was at least vaguely correct, because the Troano Codex, while not a history of the Lemurian cataclysm, is a kind of astrological almanac describing natural catastrophes as the delineators of world epochs.

Le Plongeons Sacred Mysteries Among the Mayas and Quiches 11,500 Years Ago and Queen Moo and the Egyptian Sphinx were important influences in the work of James Churchward, who brought the subject to a wider reading audience beginning in the early 20th century, and they remain valued, if flawed contributions to Lemurian studies.
