[Illustration: FIG. 40.--Eccentrically shaped implements found at summit of mound.] [Illustration: FIG. 41.--Flint object found at base of stela.] [Illustration: FIG. 42.--Flint object found at base of stela.] Among these three large pyramidal structures are conspicuous, which no doubt at one time carried small temples upon their summits, some remains of which are still to be seen. At the base of these pyramids stand three small plain stelæ, quite unornamented. Upon the summit of one of these mounds the eccentrically shaped implements shown in figures 40 and 44 were found. Of these, figure 40, _a_, _b_, and figure 44, _m_, _n_, _o_, _p_, are of obsidian, while the rest are of flint. Sixty-four of these objects were found in all, at depths varying from one or two inches to a foot beneath the surface; all were within an area of about 2 square yards. Some of the objects, especially the obsidians, were chipped out with great care and accuracy; others were merely flint flakes with a few shallow indentations chipped in their sides. On the south side of the largest of the pyramids stood a large sculptured stela, the upper part of which had been broken off and lay close to the lower part, which was still embedded in cement. The sculptured part of this stela measured 10 feet 2 inches in length by 4 feet 3 inches in breadth, and about 16 inches in thickness. The sculpture, which is in low relief, represents a captive, or sacrificial victim, prone on his face and knees, while above him rises the figure of the priest or warrior, with elaborately decorated feather headdress, holding in his extended right hand a small figure of the manikin god. The limestone from which the stela is cut has been very much defaced by the weather, and the finer details of the sculpture can not now be deciphered. The back and sides are plain and unsculptured. Close to this monolith lay a small stone altar, 2 feet 6 inches by 2 feet 4 inches; on its upper surface is represented the figure of a skeleton with head bent over the extended right arm, while the left is held in to the side, the elbow joint at right angles. In front of the skeleton is a double row of hieroglyphs, each row containing 7 glyphs, most of which are in a fairly good state of preservation. An excavation was made round the part of the monolith still standing. It was found to be surrounded by a solid foundation of blocks of limestone, held together by cement, among which were found, near the base of the stela, and actually in contact with it, the two eccentrically shaped flint objects shown in figures 41 and 42. In excavating a stela at the ruins of Naranjo, Republic of Guatemala, Teobert Maler found the flint illustrated in figure 43, _a_, and in clearing another stela at the same ruins 24 similar flints were found (fig. 43, _b-s_). Of these he says: [Illustration: FIG. 43.--Flints found in ruins at Naranjo.]
