Another singular coincidence (we may remark) occurs in the measurement of the terraced-pyramid at Mexican Cholula; the base of that is 5760 feet!--now the base of the Egyptian, as shewn above, is 2884 feet only; this sum multiplied by two, produces a sum total of 5768; a difference only of _eight feet_, would make the Pyramid of Cholula _exactly twice_ as large as that of Egypt. An error may have occurred in reference to the eight feet--for in so large a measurement, and by different authors, it is but natural that an error might arise, and consequently these bases, as to size, cannot be viewed as accidental. "Near the South-west corner of the river-wall, and the South-wall, is a recess, which was probably once occupied by _a colossal monument_ fronting the water--no part of which is now visible. Beyond are the remains of _two small pyramidal structures_, to the largest of which is attached a wall running along the west bank of the river. This appears to have been one of the principal walls of the city, and between the _two pyramids_ there seems to have been a gateway or principal entrance from the water. The South wall runs at right angles to the river, beginning with a range of steps about thirty feet high, and each step about eighteen inches square. At the South-east corner is _a massive pyramidal structure_ one hundred and twenty feet high on the slope. On the right are other remains of terraces and _pyramidal buildings_, and here, also, was probably a gateway, by a passage about twenty feet wide, into a quadrangular area two hundred and fifty feet square, _two sides of which are massive pyramids_ one hundred and twenty feet on the slope. At the foot of these structures, and at different parts of the quadrangular area, are numerous remains of _sculpture_, especially a _colossal monument, richly sculptured_, fallen and ruined. Behind it _fragments of sculpture_, thrown down from their places by trees, are strewed and lying loose _on the side of the pyramid, from the base to the top_. 'Idols' give a peculiar character to the ruins of Copan. One stands with its face _to the East_ [_i. e._ to the Rising Sun] about six feet from the base of the pyramidal wall. It is _thirteen feet high, four feet in front and back_, and _three feet on the sides_ [_i. e._ four-sided column] _sculptured on all four of its sides, from the base to the top_, and one of the richest and most elaborate specimens in the whole extent of ruins. Originally, it was _painted_, the marks of _red colour_ being distinctly visible. Before it at the distance of about eight feet, is a large block of sculptured stone, which the Indians call an altar. The subject of the front [_i. e._ of the Idol-obelisk] is a full-length figure, the face wanting beard, and of a feminine cast, though the dress seems that of a man. On the two sides are rows of _hieroglyphics_ [_i. e._ the sacred or religious language] which probably recite the history of this mysterious personage. Following
