"No doubt they were emblematic of some religious belief, and, in the minds of the imaginative people passing between them, must have excited feelings of solemn awe. The platform on the mound is about sixty feet square and is crowned by a building measuring forty-three by forty-nine feet. Single doorways face the east, south and west, having massive lentils of zapote wood, covered with elaborate carvings, and the jambs are ornamented with sculptured figures. The sculpture is much worn, but the head-dress of feathers and portions of the rich attire still remain. The face is well preserved and has a dignified aspect. All the other jambs are decorated with sculptures of the same general character, and all open into a corridor six feet wide, extending around three sides of the building. The interior of this building was ornamented with very elaborate but much obliterated carvings. "The sacred character of this remarkable structure is apparent at the first glance, and it is equally obvious that the various sculptures must have some significance. The entrance between the two colossal serpents' heads remind us at once of Gomera's description of the entrance to the temple of Quetzalcoatl in Mexico, which 'was like unto the mouth of a serpent and which was a thing to fear by those who entered in thereat.'" The circumstance that these heads are feathered seems further to connect this temple with the worship of that divinity. But in the figures sculptured upon the jambs of the entrances, and which, Mr. Stephens observes, were of the same general character throughout, we have further proof that this structure was dedicated to a serpent divinity. Let it be remembered that the dignified personage there represented is accompanied by a feathered serpent, the folds of which are gracefully arrayed behind the figure and the tail of which is marked by the rattles of the rattle-snake--the distinguishing mark of the monumental serpent of the continent, whether represented in the carvings of the mounds or in the sculptures of Central America. This temple, we may therefore reasonably infer, was sacred to the benign Quetzalcoatl, or a character corresponding to him, whose symbolical serpent guarded the ascent to the summit, and whose imposing representation was sculptured on its portals. This inference is supported by the fact that in Mexican paintings the temples of Quetzalcoatl are indicated by a serpent entwined around or rising above them, as may be seen in an example from the Codex Borgianus in Kingsborough.
