This pyramidal structure, or Great Temple, as it is generally called, was perhaps rather the base of a religious structure, than the religious edifice itself. We possess no accurate drawing of it among the contemporary or early relics of the conquest, that have descended to us; but it is known to 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. [Illustration: RESTORATION OF GREAT TEMPLE.] When Cortéz arrived in front of this truncated pyramid, two priests and several caciques were in attendance, by order of Montezuma, to bear him in their arms to its summit. But the hardy conqueror declined this effeminate means of transportation, and marched up slowly at the head of his soldiers. On the paved and level area at the top, they found a large block of jasper, the peculiar shape of which showed it was the stone on which the bodies of the unhappy victims were stretched for sacrifice. Its convex surface, rising breast high, enabled the priest to perform more easily his diabolical task of removing the heart. Besides this, there were two sanctuaries erected on the level surface of the _Teocalli_; two altars, glowing with a fire that was never extinguished; and a large circular drum, which was struck only on occasions of great public concern.
