the limits which I have marked out." Then he said aloud what auspicia he sought for (_i.e._ whether of birds, lightning, or what); and when they appeared, Numa descended as rex from the citadel. This process was called _inauguratio_; it is attested for the confirmation of the election of the three flamines maiores, the rex, and the augurs, in historical times,[355] whatever was the method of that election, and without it the priest was not believed to be acceptable to the gods. It is not mentioned by Roman writers in connection with the Pontifices or the Vestals; if this be not merely from dearth of evidence, it is not easy to account for, unless the reason were that neither body was specially concerned with sacrifice. But the principle is perfectly clear--that the person who is to represent the community in worship must be one of whom the _numina_ openly express approval. A priest, _sacerdos_, is thus a person set apart by special ritual for the service of the _sacra populi Romani_. The rex no doubt himself made the selection and supervised the inauguratio of the other priests at whose head he was. When the kingship came to an end, his powers of this kind passed to the pontifex maximus; and it may be as well to add at once that his sacrificial powers, though they were in a special sense inherited by a priest who took his title, the _rex sacrorum_, passed with the civil power to all magistrates _cum imperio_, who wore the _toga praetexta_ symbolic of priestly function, and had the right of presiding at sacrificial rites both at home and in the field. Thus magistrate and priest, though quite distinct under the Republic from the point of view of public law, have certain characteristics in common as deriving from a common source in the powers of the rex.[356] But to return to the period of Numa and the calendar: it was not only necessary that the priest should be acceptable to the gods, but that he should be marked off from the rest of the community as being dedicated to their service. As Dr. Jevons says,[357] in all early religions priests are marked off from other worshippers, partly by what they do, and partly by what they may not do; and what he means is (1) that the priest originally was the person who alone could slay a victim; (2) that in consequence of his sacredness he was subject to a great number of restrictions. I have already spoken of these restrictions or priestly taboos in my second lecture; and as I believe that in the period we are now dealing with they were little more than a survival, I shall not return to them now. But of the outward insignia, which marked off the priest as alone entitled to perform the essential act of worship, the sacrifice, and which bring him out of the region of the _profanum_ into that of _sacrum_, I must say a few words before going farther.
