Ethnological Types._--Atlantis as we shall see is said to have beeninhabited by red, yellow, white and black races. It is now proved bythe researches of Le Plongeon, De Quatrefages, Bancroft and othersthat black populations of negroid type existed even up to recent timesin America. Many of the monuments of Central America are decoratedwith negro faces, and some of the idols found there are clearlyintended to represent negros, with small skulls, short woolly hair andthick lips. The Popul Vuh, speaking of the first home of theGuatemalan race, says that "black and white men together" lived inthis happy land "in great peace," speaking "one language." (SeeBancroft's _Native Races_, p. 547.) The Popul Vuh goes on to relatehow the people migrated from their ancestral home, how their language_became altered_, and how some went to the east, while other travelledwest (to Central America).
