From the construction of their temples, all religious services were public. The long processions of priests, winding round their massive sides, as they rose higher and higher towards the summit, and the dismal rites of sacrifice performed there, were all visible from the remotest corners of the capital, impressing on the spectator’s mind a superstitious veneration for the mysteries of his religion, and for the dread ministers by whom they were interpreted. This impression was kept in full force by their numerous festivals. Every month was consecrated to some protecting deity; and every week, nay, almost every day, was set down in their calendar for some appropriate celebration; so that it is difficult to understand how the ordinary business of life could have been compatible with the exactions of religion. Many of their ceremonies were of a light and cheerful complexion, consisting of the national songs and dances, in which both sexes joined. Processions were made of women and children crowned with garlands and bearing offerings of fruits, the ripened maize, or the sweet incense of copal and other odoriferous gums, while the altars of the deity were stained with no blood save that of animals.[123] These were the peaceful rites derived from their Toltec predecessors, on which the fierce Aztecs engrafted a superstition too loathsome to be exhibited in all its nakedness, and one over which I would gladly draw a veil altogether, but that it would leave the reader in ignorance of their most striking institution, and one that had the greatest influence in forming the national character. Human sacrifices were adopted by the Aztecs early in the fourteenth century, about two hundred years before the Conquest.[124] Rare at first, they became more frequent with the wider extent of their empire; till, at length, almost every festival was closed with this cruel abomination. These religious ceremonials were generally arranged in such a manner as to afford a type of the most prominent circumstances in the character or history of the deity who was the object of them. A single example will suffice.
