For many years Augustus himself avoided the definite establishment of his own position as even a life tenancy. His office of Imperator was renewed every ten years; the Tribunician power was granted to him afresh every year in form, though not in fact; the Censorian office was taken up every five years; he did not become Pontifex Maximus till eighteen years after the battle of Actium; the only office which he held without a break--that of Princeps Senatus--was not considered to be an office at all, the dignity of the first man in the Senate being constitutionally purely of respect. Under these circumstances it would be strange if the historians were correct in assuming that the chief preoccupation of his life was in providing for a successor of his own blood. Tacitus, who is full of the dynastic question, informs us, with his customary inconsistency, that Augustus himself at the end of his life mentioned three men not connected with the Cæsarean race as possible candidates for the succession, which he could hardly have done had he accepted the hereditary principle, seeing that the Cæsarean stock was by no means extinct. For a short time the vision of hereditary succession probably attracted the imagination of Augustus, and certainly always occupied the attention of members of his family; but the early deaths of two of his grandsons and the insubordination of a third quickly dispelled the attractive vision. The acquiescence of other Roman families in the Cæsarean rule was bought partly by admission to a share in the administration, partly by the very fact that the dynastic ideal was not forced in such a manner as to preclude all possibility of a change in the form of government, and a reversion to the happy days of the Senatorial oligarchy. Opposition was further disarmed by intermarriages with the houses least likely to submit contentedly to the domination of one family; both stocks of the Claudians, the Antonians, the Domitians, the Æmilians, the Junians, and others were thus united with the Julians in the lifetime of Augustus or his successor. The consular lists for the reign of Augustus recall the names of the noblest Roman families, and though the old city offices had now become titular rather than effective, men still liked sitting in Curule chairs, and taking the lead in the pageantry which survived the reality of power; the process by which administrative functions gradually passed from the old offices to the new hierarchy was a slow one, and an ambitious young man might still think he had embarked on a career when he had been dignified with the lowest of the old magistracies. The new men were employed less in Italy than in the imperial provinces, where indeed it was important that the officials should be attached to the person of the Emperor rather than to the abstraction called the Senate and the people of Rome. Neither Augustus nor Tiberius were afraid to entrust the really
