For if the Egyptian colonists, at the time of their emigration to America, had advanced no further toward the perfect pyramid than the mound-building stage, would it not be the merest coincidence if the finished pyramidal structures in one country, the result of centuries of improvement, should resemble those of the other country in any but the most general features? Finally, pyramidal edifices were common in Asia as well as in Northern Africa, and it may be said that the American pyramids are as much like the former as they are like the latter.[I-128] In its general features, American architecture does not offer any strong resemblances to the Egyptian. The upholders of the theory find traces of the latter people in certain round columns found at Uxmal, Mitla, Quemada, and other places; in the general massiveness of the structures; and in the fact that the vermilion dye on many of the ruins was a favorite color in Egypt.[I-129] Humboldt, speaking of a ruined structure at Mitla, says: "the distribution of the apartments of this singular edifice, bears a striking analogy to what has been remarked in the monuments of Upper Egypt, drawn by M. Denon, and the savans who compose the institute of Cairo."[I-130] [Sidenote: SCULPTURE AND HIEROGLYPHICS.] Between American and Egyptian sculpture, there is, at first sight, a very striking general resemblance. This, however, almost entirely disappears upon close examination and comparison. Both peoples represented the human figure in profile, the Egyptians invariably, the Americans generally; in the sculpture of both, much the same attitudes of the body predominate, and these are but awkwardly designed; there is a general resemblance between the lofty head-dresses worn by the various figures, though in detail there is little agreement.[I-131] These are the points of analogy and they are sufficiently prominent to account for the idea of resemblance which has been so often and so strongly expressed. But while sculpture in Egypt is for the most part in intaglio, in America it is usually in relief. In the former country, the faces are expressionless, always of the same type, and, though executed in profile, the full eye is placed on the side of the head; in the New World, on the contrary, we meet with many types of countenance, some of which are by no means lacking in expression. If there were any hope of evidence that the civilized peoples of America were descendants, or derived any of their culture from the ancient Egyptians, we might surely look for such proof in their hieroglyphics. Yet we look in vain. To the most expert decipherer of Egyptian hieroglyphics, the inscriptions at Palenque are a blank and unreadable mystery, and they will perhaps ever remain so.[I-132]
