At the altars of the emperor even slaves found protection against harshness or inhumanity on the part of their masters. Augustus so highly prized the bestowal of this protective office of Tribune of the people, that he even had the day (27th of June, 23 B.C.) recorded on coins and monuments as the beginning of his reign. Three years later the imperial power received its consummation in the grant of the consular authority to Augustus for the term of his life, with the right to nominate his colleagues or representatives and to propose them for election, and with an extension of the right of issuing legal ordinances (edicts). From that time forward he took his seat in the senate upon a curule chair placed at a higher level between the two consuls. By these means all political power was concentrated in his person, and when, soon after, the office of pontifex maximus fell vacant by the death of Lepidus, Augustus had this dignity also conferred upon himself, and thus combined the authority of high priest with supreme political power. In virtue of this office the care of the state religion and public worship, the interrogation of the oracular books and the interpretation of their utterances, the appointments to priestly offices and even the choice of vestals, devolved upon the emperor. And as through the fulness of his consular and imperatorial power he exercised the highest judicial authority over the army and in all cases affecting the safety of the state, so as supreme pontifex he had the right of deciding upon all violations of religion and transgressions of the priesthood. TIGHTENING THE REINS OF POWER This union of the hierarchic with the temporal power completed the skilfully constructed edifice of the principate. By this means the whole executive and judicial authority in matters spiritual and temporal, human and divine, was placed in the hands of the emperor, and if for a while the people retained the show of legislative power it was a mere shadow of the ancient sovereignty of the people, since the legal tradition which gave magisterial edicts the force of law during the magistrate’s tenure of office reduced every other kind of legislative authority to an empty form when all official power was centred in a person who held office for life. The imperial decrees were legally valid throughout the empire. They formed the nucleus and basis of the “constitution” which in process of time ranked on an equality with the comitial laws. The wise moderation of Augustus--which induced him to ask the opinion or approval of the senate in all decrees concerning peace and war and withheld him from exercising the power of life and death which he possessed over senators and citizens in an offensive manner, and led him to treat traditional forms with reverential observance--conduced greatly to the establishment and preservation of the legislative authority of the emperor.
