CHAPTER IV. 1519–1520.

have been pyramidal in shape, over one hundred and twenty feet in altitude, with a base of three hundred and twenty. It stood in a large area, surrounded by a wall eight feet high, sculptured with the figures of serpents in relief. From one end of the base of this structure, a flight of steps rose to a terrace at the base of the second story of the pyramid. Around this terrace, a person, in ascending, was obliged to pass until he came to the corner immediately above the first flight, where he encountered another set of steps, up which he passed to the second terrace, and so on, continuously, to the third and fourth terraces, until, by a fifth flight, he attained the summit platform of the Teocalli. These spaces or terraces, at each story, are represented to have been about six feet in width, so that three or four persons could easily ascend abreast. It will be perceived that in attaining the top of the edifice it was necessary to pass round it entirely four times and to ascend five stairways. Within the enclosure, built of stone and crowned with battlements, a village of five hundred houses might have been built. Its area was paved with smooth and polished stones, and the pyramid that rose in its centre seems to have been constructed as well for military as religious purposes, inasmuch as its architecture made it fully capable of resistance as a citadel; and we may properly assume this opinion as a fact, from the circumstance that the enclosing walls were entered by four gates, facing the cardinal points, while over each portal was erected a military arsenal filled with immense stores of warlike equipments.
