Lastly, the fourth palace, situated on the eastern side of the square, is the most splendid, and at the same time the most gloomy of all. It is called the Iztlacat-expan, or Palace of the Prophets. It is the residence of the priests. It would be impossible to describe the mysterious, sad, and cold appearance of this residence; the windows of which are covered with a wicker frame, so closely interwoven, as almost to entirely exclude the light of day. A gloomy silence perpetually prevails in this building; but at times, in the middle of the night, when all are reposing in the city, the Indians awake in terror at the strange sounds that appear to issue from the Iztlacat-expan. What is the life of men who inhabit it? In what do they spend their time? No one knows. Woe to the imprudent man, who, curious for information on this point, would try to surprise the secrets of which he should remain in ignorance; for the vengeance of the insulted priests would be implacable.
If the vow of chastity be imposed on the vestals, it is not so with regard to the High Priest and his assistants; still we must remark, that very few of them marry, and all abstain, at least openly, from any connection with the other sex. The noviciates of the priests lasts ten years, and it is only at the expiration of that period, and after undergoing numberless trials, that the novices assume the title of Chalchiuh. Until then they can alter their minds, and embrace another career; but the case is extremely rare. It is true, that if they took advantage of the law's permission, they would be infallibly assassinated by their brothers, who would fear seeing a portion of their secrets unveiled to the public. In other respects the priests are highly respected by the Indians, whose love they contrive to acquire; and we may say, that next to the chief, the Amanani is the most powerful man in the tribe.
Among peoples with whom religion is so powerful a lever, it may be observed that the temporal and spiritual power never come into collision; each knows how far his attributes extend, and follows the line traced for him, without trying to infringe on the rights of the other. Owing to this intelligent diplomacy, priests and chiefs act in concert, and double their strength.
