circular corridor, four feet wide, and in the centre is a circular mass, apparently of solid stone, seven feet six inches in diameter; but in one place, at the height of eleven feet from the floor, was a small square opening, which I endeavoured to clear out but without success. The roof was so tottering that I could not discover to what this opening led. The walls of both corridors were plastered and covered with paintings, and both were covered with a triangular arch." Mr. Stephens also found at Mayapan, which city, as we have seen, was built by Ku Kulcan, the great ruler and demi-god of Chichen-itza, a dome-shaped edifice of much the same character with that here described. It is the principal structure here, and stands on a mound thirty feet high. The walls are ten feet high to the top of the lower cornice, and fourteen more to the upper one. It has a single entrance towards the west. The outer wall is five feet thick, within which is a corridor three feet wide, surrounding a solid cylindrical mass of stone, nine feet in thickness. The walls have four or five coats of stucco and were covered with remains of paintings, in which red, yellow, blue and white were distinctly visible. On the south-west of the building was a double row of columns, eight feet apart, though probably from the remains around, there had been more, and by clearing away the trees others might be found. They were two feet and a half in diameter. We are not informed upon the point but presumably the columns were arranged, in respect to the structure, in the same manner as those accompanying the dagobas of Ceylon, or the mounds of Chichen-itza.
