The pyramid was composed of blocks of hewn stone, so accurately fitted together as hardly to show the joints, and the carving goes on without interruption from one block to another. Some of these blocks are eight feet long, and nearly three feet wide. They were laid together without mortar, and indeed, from the construction of the building, none was required. The first storey is about sixteen feet high, including the plinth at the bottom. Above the plinth comes a sculptured group of figures, which is repeated in panels all round the pyramid, twice on each side. Each panel occupies a space thirty feet long by ten in height, and the bas-reliefs project three or four inches. There is a chief, dressed in a girdle, and with a head-dress of feathers just like those of the Red Indians of the north. Below the girdle he terminates in a scroll. In the middle of the group is what may perhaps be a palm-tree, with a rabbit at its foot. Close to the tree, and reaching nearly to the same height, is a figure with a crocodile’s head wearing a crown, and with drapery in parallel lines, like the wings of the creatures in the Assyrian bas-reliefs. Indeed this may very likely be a conventional representation of the robes of feather-work so characteristic of Mexico. [Illustration: SCULPTURED PANEL, From the ruined Pyramid of Xochicalco. (_After Nebel_.)] Above these bas-reliefs is a frieze between three and four feet high, with another sculptured panel repeated eight times on each side of the pyramid. This remarkable sculpture represents a man sitting barefoot and crosslegged. On his head is a kind of crown or helmet, with a plume of feathers; and from the front of this helmet there protrudes a serpent, just where in the Egyptian sculptures the royal basilisk is fixed on the crowns of kings and queens. The eyes of this personage are protected by round plates with holes in the middle, held on by a strap round the head, like the coloured glasses used in the United States to keep off the glare of the sun, and known as “goggles.” In front of this figure are sculptured a rabbit and some unintelligible ornaments or weapons. “Rabbit” may have been his name. The frieze is surmounted by a cornice; and above the cornice of the second storey enough remains to show that it was covered with reliefs, in the same way as the first There were five storeys originally: the others have only been destroyed about a century. The former proprietor of the hacienda of Temisco pulled down the upper storeys, and carried away the blocks of stone to build walls and dams with.
