There was also an order of females who were admitted to the practice of all the sacerdotal functions, omitting only that of human sacrifice. These appear to have been more of the description of nuns than of priestesses. Fakirs and religious beggars also abounded, but these seem to have taken upon themselves mendicant vows for a space only.

Education was wholly sacerdotal. That is, though secular studies were communicated to the young, the principal part of their training consisted of religious instruction. The schools were situated in the temple precincts, and entering these at an early age the boys were instructed by priests, and the girls by nuns. They resided within the temple buildings, and those who did not, and who probably consisted of the lower orders, were enrolled in a society called the Telpochtiliztli, which met every evening at sunset to perform choral dances in honour of Tezcatlipoca. A secondary school also existed, called the Calmecac, in which the lore of the priests and the reading of the hieroglyphs, astrology, and the kindred sciences were taught the young men, whilst the girls became experts in the weaving of costly garments for the adornment of the idols, and the wear of the higher orders of the hierarchy.

When the boys and girls left the school at the age of fifteen they were either sent back to their families, or to public service, to which they were often recommended by the priests. Others remained to become in their turn priests or nuns in different convents.

Severe educational tests were required for entrance into the priesthood, and grades were many. The priests, we have seen, might occupy one of several ranks, and the nuns could become abbesses, or merely retain the position of simple sisters, according to their ambition and abilities. The lower ranks were designated Cihuaquaquilli, or 'lady herb-eaters,' while the higher orders were known as Cihuatlamacasque, or 'lady deaconesses.'

The Spanish conquerors of Mexico were astonished to find among this peculiar people a number of rites which appeared in many respects analogous to some of those practised by Catholics. Such were the use of the cross as a symbol, communion, baptism, and confession. The cross, which was designated, strangely enough, 'Tree of our Life,' was merely the symbol of the four winds, which were indeed the life of Anahuac. As regards confession and absolution, these were permitted to a person only once in his existence, and that at a late period of life, as any repetition of the pardoned offence was held to be inexpiable. Penance was apportioned, and absolution given much in the same manner as in the Roman Catholic Church. There appears to have been more than one kind of communion. At the third festival of Huitzilopochtli they made an image of him in dough kneaded with the blood of infants, and divided the pieces among themselves. In the case of Xiuhtecutli a similar image was placed on the top of a tree, which, like our Christmas trees, had been transported from the forest to the town, and when the tree was thrown down and the image broken, the people scrambled for the pieces, which they devoured.

In the rite of baptism the principal functionary was the midwife. She touched the mouth and breast of the infant with water in the presence of the assembled relations, and invoked the blessing of the goddess Cihuatcoatl, who presided over childbirth (and who was a variant of Centeotl, the maize-goddess) upon it. But it is unlikely that she did so in the devoutly Christian language ascribed to her by Sahagun.

At death the corpse of a Mexican was dressed in the robes peculiar to his guardian deity, and in this can be perceived an analogy to every dead Egyptian becoming an Osirian, or Osiris himself. Covered with paper charms, as the Egyptian mummy was covered with metal or faïence symbols, the body was cremated, the ashes placed in an urn, and preserved in the house of the deceased. At the death of a rich man many slaves were sacrificed to bear him company in the world beyond the grave. This was obviously a meaningless survival of a prehistoric custom. Valuable treasures were often buried with the wealthy, and a rich man would often have his private chaplain sacrificed at his tomb to assist him with ghostly counsel and comfort in the other world.

Among the ancient Mexicans every month was consecrated to some particular deity, and in their calendar every day marked a celebration of some greater or lesser divinity. Those differed considerably in their character. Some were light and joyous, and their ritual abounded in the use of flowers and song. Others (and these, unhappily, were in the majority) were stained with the hideousness of human sacrifice.

The temples of the Ancient Mexicans were very numerous. They were called teocallis,[4] or 'houses of God,' and were constructed by facing huge mounds of earth with brick and stone. They were pyramidal in shape, and built in stages which grew smaller as the summit was reached. The bases of some of these teocallis were more than one hundred feet square. The great teocalli at Mexico, for example, was three hundred and seventy-five feet long at the base, and three hundred feet in width. Its height was over eighty feet. It consisted of five stages, each communicating with the other by means of a staircase which wound around the entire edifice. In the case of some teocallis, however, the staircase led directly up the western face of the building. At the top two towers, between forty and fifty feet in height, stood perched upon a broad area. Inside these were kept the idols of the gods to whom the teocalli was sacred. Before these towers stood the stone of sacrifice, and two altars upon which the fires blazed night and day. In the city of Mexico six hundred of these fires rendered any artificial illumination at night superfluous. Through the very construction of these temples all religious services were of a public nature. In front of the great teocalli of Mexico stretched a court twelve hundred feet square, around which clustered the chapels of minor deities, and those captured from conquered peoples, as well as the dwellings and offices set apart for the attendant priests.

Although it appears that the Toltecs, the forerunners of the Aztecs in Mexico, had at one period of their history been prone to human sacrifice, they had almost entirely discarded the practice at the time of their downfall. Some two hundred years before the coming of the Spaniards the Aztecs had adopted this abomination, and were in the habit of sparing the lives of immense numbers of prisoners of war solely for the purpose of offering them up to the national gods. As their empire extended, these holocausts became greater and more common. On the teocalli of Mexico the Spaniards could count one hundred and thirty-six thousand human skulls piled in a horrid pyramid.
