Just as the dynasty of the Ptolemies had been surrounded by a semi-religious veneration, Caligula, inspired as he was by Egyptian and Ptolemaic conceptions, sought to have this same veneration bestowed upon his entire family--that family which under Tiberius had been persecuted and defamed by suits and decimated by suicides through the envy of the aristocracy, which was forever unwilling to forgive its too great prestige. Caligula not only hastened to set out in person to gather up the bones of Agrippina, his mother, and of his brother, in order to bring them to Rome and deposit them piously in the tomb of Augustus,--that was a natural duty of filial piety,--but he also prohibited any one to name among his ancestors the great Agrippa, the builder of the Pantheon, because his very obscure origin seemed a blot upon the semi-divine purity of his race. He had the title of Augusta and all the privileges of the vestal virgins bestowed upon his grandmother Antonia, the daughter of Mark Antony and the faithful friend of Tiberius; he had these same vestal privileges bestowed upon his three sisters, Agrippina, Drusilla, and Livilla; he had assigned to them a privileged position equal to his own at the games in the circus; he even had it decreed that their names should be included in the vows which the magistrates and pontiffs offered every year for the prosperity of the prince and of his people, and that in the prayers for the conservation of his power there should also be included a prayer for their felicity. This was a small revolution from the constitutional point of view; for the Romans, though allowing their women ample freedom to occupy themselves with politics from the retirement of their homes, had never recognized for them any official capacity. Tiberius, faithfully adhering in this also to tradition, had gone as far as to prevent the senate, at the time of Livia's death, from voting public honors to her memory, which, he thought, might have justified the belief that his mother had been, not a matron of the old Roman stamp, but a public personage. Caligula, however, was quite indifferent to tradition, and by his expressed will, as if in reaction against the persecutions and the humiliations which the imperial family had suffered under Tiberius, even the sisters of the emperor acquired a sacred character and a privileged position in the state. For the first time the women of the imperial family acquired the character of official personages.
