The sacerdotal order, though numerous, was not distinguished by any peculiar badge or costume from the rest of the nation. Neither was it the sole depository of the scanty science of the country, nor was it charged with the business of instruction, nor with those parochial duties, if they may so be called, which bring the priest in contact with the great body of the people, - as was the case in Mexico. The cause of this peculiarity may probably be traced to the existence of a superior order, like that of the Inca nobles, whose sanctity of birth so far transcended all human appointments, that they in a manner engrossed whatever there was of religious veneration in the people. They were, in fact, the holy order of the state. Doubtless, any of them might, as very many of them did, take on themselves the sacerdotal functions; and their own insignia and peculiar privileges were too well understood to require any further badge to separate them from the people. The duties of the priest were confined to ministration in the temple. Even here his attendance was not constant, as he was relieved after a stated interval by other brethren of his order, who succeeded one another in regular rotation. His science was limited to an acquaintance with the fasts and festivals of his religion, and the appropriate ceremonies which distinguished them. This, however frivolous might be its character, was no easy acquisition; for the ritual of the Incas involved a routine of observances, as complex and elaborate as ever distinguished that of any nation, whether pagan or Christian. Each month had its appropriate festival, or rather festivals. The four principal had reference to the Sun, and commemorated the great periods of his annual progress, the solstices and equinoxes. Perhaps the most magnificent of all the national solemnities was the feast of Raymi, held at the period of the summer solstice, when the Sun, having touched the southern extremity of his course, retraced his path, as if to gladden the hearts of his chosen people by his presence. On this occasion, the Indian nobles from the different quarters of the country thronged to the capital to take part in the great religious celebration.
