To establish that the Aborigines of South and Central (_i. e._ Mexican) America, were from the Last of the Tyrian family in Asia, the following arguments and evidences have been produced: viz.--The separation of the Aborigines of the Western Hemisphere into two distinct races, or people;--and that division justified by absolute contrasts in their moral and physical condition and manners,--in their political and Religious customs and observances;--and in addition to these powerful contrasts, is the fact,--that _North_ America possesses _no Architectural stone ruins_,--while in the Mexican portion of the Continent, many Cities and Temples have been found. The great and injurious error of naming the Aborigines--"INDIANS"--was pointed out,--as well as the Author, and the cause of the misnomer, and its effects. The title of the first Epoch was then given, and the arrangement of the several propositions for establishing its truth. An elaborate argument was next founded upon the important and interesting question,--"Are the Fine-Arts of sufficient authority, to be received in evidence, for establishing historical records or events?" Having produced an answer _con amore_,--and especially illustrated the answer, by the resuscitation of the Ruins of Rome, we proceeded in the belief that the argument was conclusive and in the affirmative. The fact was then established of the discovery of the ancient Ruins in Southern or Central America,--viz., at Mitla, Cholula, Uxmal, Palenque, Quirigua, Ocosingo, Tecpan-Guatimala, Gueguetinango, Quichē, Copan, Chi-chen, Zayi, Kabah, Espita, Ticol, and Labnah,--and these severally upon the high authority of the justly renowned Humboldt,--the Spanish Commissioners Del Rio and Waldeck,--Dupaix and Galindo,--and last, not least, the enterprising American Traveller, Stephens,--and his artist-associate, Catherwood:--and to which list may now be added the name of Norman. Stephens has investigated other Ruins in Yucatan, but they are precisely analogous to that of Uxmal. Reference was then made to the Mexican Paintings preserved in the Vatican, Bologna, and Madrid, and republished in the folio Volumes by Lord Kingsborough. Extracts followed from the descriptions of the Ruins of Copan, Palenque, and Uxmal, with such commentaries as were required, for illustration of the Architecture and Sculpture, or for detecting errors.
