"In the centre [of the Temple], and opposite the range of steps leading to the terrace, are three principal doorways. The middle one is eight feet six inches wide, and eight feet ten inches high; the others are of the same height, but two feet less in width. The centre door opens into an apartment sixty feet long, and twenty-seven feet deep [wide], which is divided into two corridors by a wall three and a half feet thick, with a door of communication between, of the same size with the door of entrance. The _plan is the same_ as that of the Corridor in front of the Palace (?) of Palenque, except that here the Corridor does not run the whole length of the building, and the back Corridor has no door of egress. The ceiling forms a _triangular Arch_, without the Key-stone, as at Palenque." The term "triangular _Arch_" cannot be admitted by the language of Architecture; he might as well have written _triangular semicircle_, terms distinctly opposed to each other. It is essential to notice this inaccuracy here, otherwise the reader may be under the erroneous impression, that the _Arch_ does exist in the ancient Ruins in America,--this is not the fact; but _the entire absence of the Arch, or its principle_, enables us to form an Architectural conclusion in reference to their identity; and the fact, _that the Arch does not exist_ in any of the Ruins of Ancient America, cannot be too forcibly impressed upon the reader's mind; for it demonstrates that these buildings were erected _before the Arch was known_, and as a consequence, is a direct proof of their great antiquity. Mr. Stephens has already written in reference to Palenque, and previously quoted, "The builders were evidently ignorant of the principles of the Arch." "The ceiling, &c.: but, instead of the rough stones overlapping or being covered with stucco, (as at Palenque) the layers of stones are bevilled as they rise, _and present an even and a polished_ surface. Throughout, the laying and the polishing of the stones are as perfect as under the rules of the best modern masonry. In this apartment we determined to take up our abode, and _under a roof, tight_ as when sheltering the heads of its former occupants." * * * * * "We were not buried in the forest as at Palenque. From every part of the terrace we looked over a field of ruins." * * * * "From the centre apartment, the divisions on each wing corresponded exactly in size and finish; and the same uniformity was preserved in the ornaments. Throughout, the roof was tight, and the apartments were dry. In one apartment, the walls were _coated with a very fine plaister of Paris_, (?) equal to the best seen on walls in this country. (United States) The rest were all of _smooth polished stone_. There were no paintings, stucco ornaments, Sculptured tablets, or other decoration whatever."
