Lost Continents

L. Sprague de Camp enjoyed debunking doubtful history and pseudoscientific claims. The work provides a detailed examination of theories and speculations on Atlantis and other lost lands, including the scientific arguments against their existence and how it has been continued, developed and imitated by later theorists, speculators, scientific enquirers, enthusiasts, occultists, quacks, and fantasists throughout history. Major speculative locales as Atlantis, Mu, and Lemuria are covered in depth, with the origins of lesser-known ones such as Thule, Hyperborea, and Rutas also treated. The work shows how the misinterpretation of Mayan writings created the Mu myth, and how the name Lemuria originated from the geological hypothesis about a land bridge between India and South Africa. Modern usage of the concept in speculative fiction is gone into, as are the various attempts to discover the "real" Atlantis.

Lost Continents by L. Sprague de Camp, Dover Publications, 1970

The 1970 edition was updated to reflect the rehabilitation of Alfred Wegener's continental drift theory and investigation of the ancient volcanic eruption of the Aegean island of Thera. This eruption is considered by many who think that Plato's account of Atlantis' destruction had an underlying historical basis, to be that basis.

De Camp's work is still one of the most reliable sources on the lost continent theme. Lost continents or ancient civilizations sunk by a deluge are a common theme in the scriptures of doctrines of many modern pseudoreligions or cults. Well-known instances include James Churchward's books on Mu, or the Theosopical portrayals of Hyperborea, Lemuria and Atlantis, and even the Nazi mythologizing about Thule. As authors of these materials tend not to state (or mis-state) their sources, works like that of de Camp are quite useful to anyone interested in objective information.

Reviewer Groff Conklin described the original edition as "a monument of scholarship [and] a richly documented and entertaining survey of how crazy the crackpots can get."[3] Boucher and McComas praised it as "a marvelously and terrifying history of the human will-to-believe, even in the face of all factual evidence."[4]
