At Tepeaca and vicinity four relics were found:—1st. A bird's, perhaps an eagle's, head sculptured in low relief within a triple circle, together with other figures, on a slab about a foot square; apparently an aboriginal coat of arms. 2d. A stone head eighteen inches high, of a hard, reddish material; the features are very regular down to the mouth, below which all is deformed. 3d. A sculptured slab, built into a wall, shown only in Kingsborough's plate. 4th. A feathered serpent coiled into a ball-like form, six feet in diameter. It was carved from a red stone, and also painted red, resting on a cubical pedestal of a light-colored stone.[IX-5]
At San Antonio, near San Andres Chalchicomula, on the eastern boundary of the state, a pyramid stands on the summit of a rocky hill. The pyramid consists of three stories, with sides sloping at an angle of about forty-five degrees, is about twenty-five feet in height, and has a base fifty-five feet square. A stairway about ten feet wide, with solid balustrades, leads up the centre of the western front; and on the top, parts of the walls of a building still remained in 1805. This summit building was said to have been in a good state of preservation only twelve years before. The material is basalt, in blocks about two by five feet, according to Dupaix's plate, laid in mortar, and all but the lower story covered with cement.[IX-6]
Stone Monster's Head.
At Quauhquelchula, near Atlixco, in the western part of the state, Dupaix noticed four relics of antiquity. 1st. A rattlesnake eight feet and a half long, and about eight inches in diameter, sculptured in high relief on the flat surface of a hard brown stone. 2d. A hard veined stone of various colors, four feet high and ten feet and a half in circumference, carved into a representation of a monster's head with protruding tusks, a front view of which is given in the cut. The rear is flat and bears a coat of arms, made up of four arrows or spears crossing a circle, with other inexplicable figures. 3d. Another coat of arms, three lances across a barred circle, carved in low relief on the face of a boulder. 4th. A human face, larger than the natural size, on the side of another boulder, and looking towards the town.[IX-7] At the town of Atlixco a very beautifully worked and polished almond-shaped agate was seen.[IX-8]
Serpent-Cup—Santa Catalina.
On the hacienda of Santa Catalina, westward from Atlixco, was found the coiled serpent shown in the cut. The material is a black porous volcanic stone, and the whole seems to form a cup, to which the head of the serpent served as a handle. Another relic from this locality was a masked human figure of the same stone.[IX-9]
