Believing, from the general and early character of the Sculpture, that Copan was the first built city in Ancient America,--we are still further warranted in the belief from the definition of the Chief Altar,--for it appears to illustrate in every particular, both by incidents and emblems, the _last_ event of Tyrus in its Asiatic history, but which was the _first_ event leading to the existence of the Tyrians in the Western Hemisphere. This important fact will be detailed in the History of Tyrus,--and at the present moment we will observe (without anticipating the event) that there is nothing in the Sculpture of the Altar, at variance with the illustration of that fact of History; but, on the contrary, every particular of the Sculpture completely defines the Nation and the incident. The _basso_ sculpture of the Altar would, also, indicate an earlier erection than the surrounding "Idols," which are in _Alto_. An analogy is, also, found in the political divisions, and the peculiar governments of the Mother-Country in Asia and Africa, and her descendants in Mexican America. In each Hemisphere there was a mixture of Monarchies and Republics;--as thus,--Sidon and Tyrus were governed by Kings--while Carthage, after the death of her first and only Monarch--Dido--became a Republic, and remained so,--and this fact created the lasting jealousy of the Romans. The same was in the Western Continent.--Mexico and other Nations were Monarchies, while other portions of the country were Republics. This is proved from the fact, that the most powerful war Montezuma the _First_ ever engaged in, was that, in which the _three Republics_ joined as a common cause against the brave, but despotic Monarch of Mexico.
