Why does he select "_bas-relievo_" only,--why not bring forth _alto-relievo_,--also,--for they are both found in Egypt and America. The Altar at Copan, and the walls at Palenque present _profile_ figures and in _bas-relievo_,--so does the Vocal Memnon of Thebes, and the walls of Egypt: at Palenque the two figures grouped at the Altar (of Casa, No. 3) are in profile, and face to face, with the Mask of Saturn between them, and holding the same general position as the two figures of the Vocal Memnon,--who are also face to face, and in profile,--but instead of the mask, they have the Egyptian Tau =T= between them, and in the act of binding it with the lotus plant. But he objects to similitude apparently from the want of analogy in the physiognomy, or profile characteristics of the relative figures of Egypt and America. This certainly then must prove that they were a different people; this we distinctly believe;--but, that that people had knowledge of Egyptian Architecture and Sculpture, _from commercial intercourse with the Nile_. _Alto-Relievo_ Sculpture is in America and Egypt:--in the former country, on the Idol-columns of Copan; in the latter nation, upon the Capitals of the Temple Columns;--and in both countries the faces are _not in profile_, but full front. The profile figures being on Temples, were supposed to be _deified_, and consequently the facial outlines were represented different from human outline. Again:--What are the Obelisks of Egypt? Are they not _square columns_ for the facility of Sculpture? and of what form are the isolated columns at Copan? Are they not _square_, and for the same purpose of facility in Sculpture with which they are covered, and with workmanship "as fine as that of Egypt?" This is a point that Mr. Stephens has passed over without even a comment! The Columns of Copan stand detached and solitary,--the Obelisks of Egypt do the same, and both are square (or four-sided) and covered with the art of the Sculptor. The analogy of being derived from the Nile is perfect,--for in what other Ruins but those of Egypt, and Ancient America, is the _square sculptured Column_ to be found? He affects to despise the Idol-Obelisks of Copan, because they do not tower in a single stone, "ninety-feet" in height like those of Egypt,--that they could not "be derived from" the latter country, because they are only one-sixth of the altitude of their prototypes!
