It was very numerous, and had a strong organization reared on an aristocratic basis, into which political calculations manifestly entered. The noblest families (including that of the monarch) had the exclusive privilege of occupying the highest sacerdotal offices. The priests of Uitzilopochtli held the primacy. Their chief was sovereign pontiff, with the title of _Mexicatl-Teohuatzin_, "Mexican lord of sacred things," and _Teotecuhtli_, "divine master." Next to him came the chief priest of Quetzalcoatl, who had no authority, however, except over his own order of clergy. He lived as a recluse in his sanctuary, and the sovereign only sent to consult him on certain great occasions; whereas the primate sat on the privy council and exercised disciplinary powers over all the other priests in the empire. Every temple and every quarter had its regular priests. No one could enter the priesthood until he had passed satisfactorily through certain tests or examinations before the directors of the _Calmecac_, or houses of religious education, of which we shall speak presently. The power of the clergy was very great. They instructed youth, fixed the calendar, preserved the knowledge of the annals and traditions indicated by the hieroglyphics, sang and taught the religious and national hymns, intervened with special ceremonies at birth, marriage and burial, and were richly endowed by taxes raised in kind upon the products of the soil and upon industries. Every successful aspirant to the priesthood, having passed the requisite examinations, received a kind of unction, which communicated the sacred character to him. All this indicates a civilization that had already reached a high point of development; but the indelible stain of the Mexican religion re-appears every moment even where it seems to rise highest above the primitive religions: amongst the ingredients of the fluid with which the new priest was anointed was the blood of an infant! The priests' costume in general was black. Their mantles covered their heads and fell down their sides like a veil. They never cut their hair, and the Spaniards saw some of them whose locks descended to their knees. Probably this was a part of the solar symbolism. The rays of the Sun are compared to locks of hair, and we very often find the solar heroes or the servants of the Sun letting their hair grow freely in order that they may resemble their god. Their mode of life was austere and sombre. They were subject to the rules of a severe asceticism, slept little, rose at night to chant their canticles, often fasted, often drew their own blood, bathed every night (in imitation of the Sun again), and in many of the sacerdotal fraternities the most rigid celibacy was enforced. You will see, then, that I did not exaggerate when I spoke of the belief that the gods were animated by cruel wills and took pleasure in human pain as having launched the Mexican religion on a path of a systematic dualism and very stern asceticism.[29]
