Immediately in connection with this singular structure and constituting part of the eastern wall, is a building, in many respects the most interesting visited by Mr. Stephens, and respecting which it is to be regretted he has not given us a more complete account. It requires no extraordinary effort of fancy to discover in the sculptures and paintings with which it is decorated the pictured records of the teachings of the deified Ku Kulcan, who instructed men in the arts, taught them in religion, and instituted government. There are represented processions of figures, covered with ornaments, and carrying arms. "One of the inner chambers is covered," says Mr. Stephens, "from the floor to the arched roof, with designs in painting, representing, in bright and vivid colours, human figures, battles, horses, boats, trees, and various scenes in domestic life." These correspond very nearly with the representations on the walls of the ancient Buddhist temples of Java, which are described by Mr. Crawfurd as being covered with designs of "a great variety of subjects, such as processions, audiences, religious worship, battles, hunting, maritime and other scenes." Among the ruins of Uxmal is a structure closely resembling the Egclesia of Chichen. It consists of two massive walls of stone, one hundred and twenty-eight feet long, and thirty in thickness, and placed seventy feet apart. So far as could be made out, they are exactly alike in plan and ornament. The sides facing each other are embellished with sculpture, and upon both remain the fragments of entwined colossal serpents which run the whole length of the walls. In the centre of each facade, as at Chichen, were the fragments of a great stone ring, which had been broken off and probably destroyed. It would therefore seem that the emblem of the entwined serpents was significant of the purposes to which these structures were dedicated. The destruction of these stones is another evidence of their religious character; for the conquerors always directed their destroying zeal against those monuments, or parts of monuments, most venerated and valued by the Indians, and which were deemed most intimately connected with their superstitions.
