I have already stated in general terms the hypothesis advanced by Brasseur de Bourbourg and some other writers. This may be called the “Atlantic” theory, for it attributes the civilization of Ancient America to the Atlantides or Atlantic race, who occupied the lost “island of Atlantis.” Brasseur de Bourbourg has studied the monuments, writings, and traditions left by this civilization more carefully and thoroughly than any other man living. He has fancies which may be safely rejected, and he has theories which, doubtless, will always lack confirmation; but he has much, also, which demands respectful consideration. There is a great deal in his books to provoke criticism; those well acquainted with the antiquities and ancient speech of Egypt may reasonably give way to a smile of incredulity while reading what he says in support of the notion that the great civilization of Egypt also came originally from this Atlantic race. Nevertheless, his volumes are important, because they furnish materials which others can use more carefully, and because he has learned to decipher some of the Central American writings and brought to view certain paths of inquiry which others may pursue with a more rigid method. As already stated, his Atlantic theory of the old American civilization is, that it was originated on this continent, but on a portion of the continent which is now below the waters of the Atlantic Ocean. It supposes the continent extended, anciently, from New Granada, Central America, and Mexico in a long, irregular peninsula, so far across the Atlantic that the Canary, Madeira, and Azores or Western Islands may be remains of this portion of it. High mountains stood where we now find the West India islands. Beyond these, toward Africa and Europe, was a great extent of fertile and beautiful land, and here arose the first civilization of mankind, which flourished many ages, until at length this extended portion of the continent was ingulfed by a tremendous convulsion of nature, or by a succession of such convulsions which made the ruin complete. After the cataclysm, a part of the Atlantic people who escaped destruction settled in Central America, where perhaps their civilization had been previously introduced. The reasons urged in support of this hypothesis make it seem plausible, if not probable, to imaginative minds.
