In the translation of the Sculpture of the Chief Altar at Copan, it was shewn that the magic Art had _portrayed the identical act of friendship_ leading to the safety of the Tyrians; and their Nation is perfectly illustrated by the accessories upon the Altar,--and having translated the Sculpture, we maintained (in humble submission to the opinion of others) that the definition of the hieroglyphics on the surface of the Altar was also arrived at,--upon the admitted ground of argument that one but illustrated the other. We have reserved a strong conclusive proof of _the correctness of the date_ assigned for the Migration until this time,--and although not necessary for evidence, yet it will (we believe) not fail to have its due effect upon the critic. We will illustrate this proof in brief chronological order: viz.-- 606 B. C.] Voyage around the continent of Africa by the Tyrians. 585 B. C.] Commencement of the first Siege of Tyrus; the mainland capital destroyed in the thirteenth year, and thence became a vassal Nation. 515 B. C.] Restoration of Tyrus as a Nation, after seventy years of vassalage from the beginning of the above siege, according to Prophecy. 484 B. C.] Herodotus wrote his History of Egypt; in it he mentions the great expedition around Africa in 606 B. C. by the Tyrians; but that voyage only, therefore, _down to his time_ [viz., 484 B. C.] the Migration to the Western Hemisphere had not been attempted, and he wrote only 152 years before the Alexandrian Siege. 332 B. C.] Siege and destruction of Tyrus by the Macedonian. Arrian makes no allusion to any migration to, or knowledge by the Tyrians of, a Western Continent, at any time during the period from Herodotus to the last Siege,--it is, therefore, a fair deduction that none took place, nor was it known to that period,--viz., 332 B. C.--but at that Siege, upon the authority of the same author, many fugitive families were rescued (during the storming of the capital) by the Sidonians.
