To each of the principal temples, lands were annexed for the maintenance of the priests. These estates were augmented by the policy or devotion of successive princes, until, under the last Montezuma, they had swollen to an enormous extent, and covered every district of the empire. The priests took the management of their property into their own hands; and they seem to have treated their tenants with the liberality and indulgence characteristic of monastic corporations. Besides the large supplies drawn from this source, the religious order was enriched with the first-fruits, and such other offerings as piety or superstition dictated. The surplus beyond what was required for the support of the national worship was distributed in alms among the poor; a duty strenuously prescribed by their moral code. Thus we find the same religion inculcating lessons of pure philanthropy, on the one hand, and of merciless extermination, as we shall soon see, on the other. The inconsistency will not appear incredible to those who are familiar with the history of the Roman Catholic Church, in the early ages of the Inquisition.[119] The Mexican temples--_teocallis_, “houses of God,” as they were called[120]--were very numerous. There were several hundreds in each of the principal cities, many of them, doubtless, very humble edifices. They were solid masses of earth, cased with brick or stone, and in their form somewhat resembled the pyramidal structures of ancient Egypt. The bases of many of them were more than a hundred feet square, and they towered to a still greater height. They were distributed into four or five stories, each of smaller dimensions than that below. The ascent was by a flight of steps, at an angle of the pyramid, on the outside. This led to a sort of terrace, or gallery, at the base of the second story, which passed quite round the building to another flight of stairs, commencing also at the same angle as the preceding and directly over it, and leading to a similar terrace; so that one had to make the circuit of the temple several times, before reaching the summit. In some instances the stairway led directly up the centre of the western face of the building. The top was a broad area, on which were erected one or two towers, forty or fifty feet high, the sanctuaries in which stood the sacred images of the presiding deities. Before these towers stood the dreadful stone of sacrifice, and two lofty altars, on which fires were kept, as inextinguishable as those in the temple of Vesta. There were said to be six hundred of these altars, on smaller buildings within the enclosure of the great temple of Mexico, which, with those on the sacred edifices in other parts of the city, shed a brilliant illumination over its streets, through the darkest night.[121][122]
