(ii.) It is plain that, on this theory of religious intervention, no priestly medium is required between the gods and their worshippers. Divination as the science of the future is an elaborate art, which cannot be possessed by the ordinary man. It requires the knowledge of ritual to compel the divine utterance; it assumes that the gods have special confidence in the select participators of an inner cultus, to whom they reveal what is hidden from the many; it requires the devotion of a lifetime, and often special rules of asceticism and purity, to interpret the hidden signs; it leads, in short, to the belief in oracular power, in the prophetic gift, in the claims of a priesthood specially set apart.[130] There was none of this at Rome. The right of invoking auspices is not a priestly gift; it is one that is possessed, in a higher degree by the magistrate, in a lower degree by all the full citizens of the primitive Roman community. It is true that there is a class of wise men, the augurs, whose chief function is the interpretation of signs, but their function is limited to interpretation; they have no more power than any private individual, and less power than the magistrate, of eliciting such a revelation. Yet, if the assistance of the augur was called in, and his interpretation given, this verdict was final. We are told that disobedience to it, at least by the magistrate in taking the public auspices, was in early times visited with a capital penalty;[131] a statement which probably means that the heads of the Roman religion, the pontiffs, reckoned such an impiety as one for which the gods would accept no expiation, and for which, therefore, the penalty of excommunication (_sacer esto_) was pronounced. The right of taking the auspices is said to have been a gift peculiar to the Patricians; but the extent of this gift can be estimated only with reference to a fourfold division of the auspices, which, from its nature, must have been primitive and not a creation of the later _disciplina_ of the augurs.
