I know of no man better qualified than was Brasseur de Bourbourg to penetrate the obscurity of American primitive history. His familiarity with the Nahua and Central American languages, his indefatigable industry, and general erudition, rendered him eminently fit for such a task, and every word written by such a man on such a subject is entitled to respectful consideration. Nevertheless, there is reason to believe that the Abbé was often rapt away from the truth by excess of enthusiasm, and the reader of his wild and fanciful speculations cannot but regret that he has not the opportunity or ability to intelligently criticise by comparison the French savant's interpretation of the original documents. At all events it is certain that he honestly believed in the truth of his own discovery; for when he admitted that, in the light of his better knowledge, the Toltec history, as recorded in the _Codex Chimalpopoca_, was an allegory--that no such people as the Toltecs ever existed, in fact--and thereby rendered valueless his own history of the Toltec period, he made a sacrifice of labor, unique, I think, in the annals of literature.

Brasseur's theory supposes that the continent of America occupied originally the Gulf of Mexico and the Caribbean Sea, and extended in the form of a peninsula so far across the Atlantic that the Canary islands may have formed part of it. All this extended portion of the continent was many ages ago engulfed by a tremendous convulsion of nature, of which traditions and written records have been preserved by many American peoples.[I-258] Yucatan, Honduras, and Guatemala, were also submerged, but the continent subsequently rose sufficiently to rescue them from the ocean. The testimony of many modern men of science tends to show that there existed at one time a vast extent of dry land between Europe and America.[I-259]

It is not my intention to enter the mazes of Brasseur's argument here; once in that labyrinth there would be small hope of escape. His _Quatre Lettres_ are a chaotic jumble of facts and wild speculations that would appal the most enthusiastic antiquarian; the materials are arranged with not the slightest regard for order; the reader is continually harassed by long rambling digressions--literary no-thoroughfares, as it were, into which he is beguiled in the hope of coming out somewhere, only to find himself more hopelessly lost than ever; for mythological evidence, the pantheons of Phœnicia, Egypt, Hindostan, Greece, and Rome, are probed to their most obscure depths; comparative philology is as accommodating to the theorist as ever, which is saying a great deal; the opinions of geologists who never dreamed of an Atlantis theory, are quoted to show that the American continent formerly extended into the Atlantic in the manner supposed.
