HOUSE OF THE MOON.
The material of the structure has generally been described as a conglomerate of small irregular stones and clay, encased, according to Humboldt and most other writers, in a wall of the porous volcanic rock, tetzontli; or this facing covered with a coating of stucco, which is salmon-colored, light blue, streaked, and red, according to the views of different observers. The Mexican commissioners disagree with all previous explorers by doing away altogether with the facing of hewn stone, and representing the facing to consist of different conglomerates arranged in successive layers, as follows:—1st, small stones from eight to twelve inches in diameter, with mud, forming a layer of about thirty-two inches; 2d, fragments of volcanic tufa as large as a man's fist, also in mud, to the thickness of sixteen inches; 3d, small grains of tetzontli, of the size of peas, with mud, twenty-eight inches thick; 4th, a very thin and smooth coat of pure lime mortar. These layers are repeated in the same order nine times, and are parallel to the slopes of the pyramid, which would make the thickness of the superficial facing about sixty feet. There have been no excavations sufficiently deep to show what may be the material in the centre. Almaraz states that a somewhat different order and thickness of the strata was observed in certain excavations, or galleries, to be described later; but none of these galleries are described as of sufficient depth to penetrate the facing of sixty feet, and the exact meaning of the report in question it is very difficult to determine. I give in a note, however, what others have said of the building-material.[IX-80]
The excavation, or gallery, already referred to, extends about twenty-five feet on an incline into the pyramid from an entrance on the southern slope, between the second and third terraces according to Mayer, about sixty-nine feet above the base according to Almaraz. It is large enough to permit the passage of a man on hands and knees, and at its inner termination are two square wells, walled with blocks of volcanic tufa three inches thick, or, as Mayer says, of adobes,—about five feet square, and one of them fifteen feet deep. No relics whatever have been found in connection with gallery or wells; Almaraz speaks of the former as simply excavations by treasure-hunters, and mentions only one well, without stating its location with respect to the gallery. Mr Löwenstern states that the gallery is a hundred and fifty-seven feet long, increasing in height to over six feet and a half, as it penetrates the pyramid; that the well is over six feet square, extending apparently down to the base and up to the summit; and that other cross galleries are blocked up by débris. Still lower on this slope, at the very base according to the plan, is a small mound like those scattered over the plain to be described later. Mr Bullock claims to have found on the summit, in 1823, walls of rough stones, eight feet high and three feet thick, forming a square enclosure fourteen by forty-seven feet, with a doorway on the south, and three windows on each side. This author's unsupported statements may be taken always with some allowance for the play of his imagination.
HOUSE OF THE SUN.
Some eight hundred and seventy-five yards south of the House of the Moon, between it and the Rio San Juan, at B of the plan, stands the Tonatiuh Itzacual, or 'house of the sun,' also called sometimes in tradition, according to Brasseur and Veytia, Tonacatecuhtli, 'god of subsistence.' In material, form, and construction, it is precisely the same, so far as my authorities go, as its northern companion; indeed, many of the remarks which I have quoted in the preceding description, were applied by the authors to both pyramids alike. Its dimensions are, however, considerably larger, and its sides vary about sixteen degrees from the cardinal points. It measures at the base seven hundred and thirty-five feet from east to west, and is two hundred and three feet high. Beaufoy estimated the size of the summit platform at sixty by ninety feet.[IX-81]
This pyramid is in better condition than the other, and the three terraces are plainly visible, although as before no one but Almaraz has discovered that they do not extend completely round the four sides, and the latter author states that the zigzag path on the eastern slope is much more clearly defined and makes more angles than that on the House of the Moon. Beaufoy found a path leading up the slope at the north-west corner, and Humboldt's remarks about a stairway of stone blocks may apply to this pyramid as well as to the other. Bullock states that the second terrace is thirty-eight feet wide. There are no traces of buildings on the summit or of galleries in the interior, but this, like the other pyramid, has a small mound on one of its sides near the base, and this mound seems to have embankments connecting it with the road on the west. The House of the Sun is also surrounded on the north, south, and east, according to the report of the Mexican commission, by the embankment a, b, c, d, which is a hundred and thirty feet wide on the summit, and twenty feet high, with sloping sides, widening out at the extremities, a and d, into unequal rectangular platforms. It is certainly very remarkable that among the many visitors to Teotihuacan no one had found any traces of this embankment before 1864.
Twelve hundred and fifty yards still further south across the stream is the Texcalpa, 'citadel,' 'palace,' or 'stone house,' as it is called, or defined, by different writers. The Citadel is a quadrangular enclosure, whose sides measure twelve hundred and forty-six and thirteen hundred and thirty-eight feet respectively, or nine hundred and eighty-four feet square according to Linares, and are exactly parallel with those of the Pyramid of the Sun. The enclosing walls, or embankments, are two hundred and sixty-two feet thick and thirty-three feet high, except on the west side, where it is but sixteen feet high; their material not being mentioned, but presumably the same as that of the pyramids. A cross-embankment of smaller dimensions divides the square area into two unequal parts, and on its centre stands a smaller pyramid, said by Linares to be ninety-two feet high, in ruins, having traces of a stairway, or path, on its eastern slope. Two small mounds stand at the western base of the small pyramid, one is found in the western enclosure, and fourteen, averaging twenty feet in height, are symmetrically arranged on the summit of the main embankments, as shown in the plan. The Citadel in some of its features seems to bear a slight resemblance to the works at Tenampua, in Honduras, and at Monte Alban, in Oajaca.[IX-82]
PATH OF THE DEAD.
Just south of the House of the Moon a line of mounds, C D, forms nearly a circular enclosure about six hundred feet in diameter, with a small mound in the centre. From this area two parallel lines of mounds extend south 15° west, parallel also with the sides of the House of the Sun and Citadel, for two hundred and fifty rods to the Rio San Juan, forming an avenue two hundred and fifty feet wide, called by the natives, as in the Toltec traditions, Micaotli, 'path of the dead.'[IX-83] The mounds that form this avenue are of conical or semispherical form, and of different dimensions, the largest being over thirty feet in height. They are built of stone fragments, earth, and clay, and stand close together, so as to resemble in some parts a continuous embankment. Six cross-embankments divide the southern part of the Path of the Dead into compartments, three of which have a mound in their centre. Linares represents the avenue as extending four or five miles beyond the House of the Moon, to the Cerro de Tlaginga; and Mayer in his plan terminates it on the south at a point opposite the House of the Sun, where it is crossed by the modern path.
