It is easy to understand why the peace and harmony which had been reestablished for a moment in the troubled imperial family by the advent of Caligula should have been of brief duration. His grandmother and his sisters were Romans, educated in Roman ideals, and this exotic madness of his could inspire in them only an irresistible horror. This brought confusion into the imperial family, and after having suffered the persecutions of Sejanus and his party, the unhappy daughters of Germanicus found themselves in the toils of the exacting caprices of their brother. In fact, in 38, Caligula had already broken with his grandmother, whom the year before he had had proclaimed Augusta; and between the years 38 and 39, catastrophes followed one another in the family with frightful rapidity. His sister Drusilla, whom, as Suetonius tells us, he already treated as a lawful wife, died suddenly of some unknown malady while still very young. It is not improbable that her health may have been ruined by the horror of the wild adventure, which was neither human nor Roman, into which her brother sought to drag her by marriage. Caligula suddenly declared her a goddess, to whom all the cities must pay honors. He had a temple built for her, and appointed a body of twenty priests, ten men and ten women, to celebrate her worship; he decreed that her birthday should be a holiday, and he wished the statue of Venus in the Forum to be carved in her likeness.

But in proportion as Caligula became more and more fervid in this adoration of his dead sister, the disagreement between himself and his other two sisters became more embittered. Julia Livilla was exiled in 38; Agrippina, the wife of Domitius Enobarbus, in 39, and about this same time the venerable Antonia died. It was noised about that Caligula had forced her to commit suicide, and that Agrippina and Livilla had taken part in a conspiracy against the life of the emperor. How much truth there may be in these reports it is difficult to say, but the reason for all these catastrophes may be affirmed with certainty. Life in the imperial palace was no longer possible, especially for women, with this madman who was transforming Rome into Alexandria and who wished to marry a sister. Even Tiberius, the son of Drusus and co-heir to the empire with Caligula, was at about this time defeated in some obscure suit and disappeared.

Caligula therefore remained alone at Rome to represent in the imperial palace the family which only ironically can be considered as the most fortunate in Rome. Of three generations, upon whom fate seemed to have showered all the gifts of life, there remained at his side only Claudius, the clownish old man, the plaything of slaves and freedmen, whom no one molested because all could make game of him. A madman and an imbecile,—or at least one who was reputed such by everybody,—this was all that remained of the family of Augustus seventy years after the battle of Actium.

Alone, with no sisters now to elevate to the divine honors of the Roman Olympus, Caligula was reduced to hunting for wives in the families of the aristocracy. But it seems that even there could be found no great abundance of women who had all the necessary qualities to make them the Olympian consorts of so capricious a god. In three years he married and repudiated three—and in a very strange manner, if we are to trust the ancient accounts of Caligula's loves. The first was Livia Orestilla, the wife of Caius Piso. The emperor, who had seen the woman at the marriage celebration, became, we are told, so infatuated with her that he obliged the husband to divorce her; he then married her, and a few days later repudiated her. Caligula is said to have compared himself on this occasion to Romulus who ravished the Sabine woman, and to Augustus who raped Livia. The second was Lollia Paulina, wife of Caius Memmius, proconsul of a distant province. Caligula heard of the prodigious beauty of Lollia's grandmother. The portrayal of her charms made him fall in love with her granddaughter, though absent and distant. He gave orders for her immediate recall to Rome, and as soon as she could be divorced from her husband he married her. This union, like the former one, lasted only a brief time. The third wife was Milonia Caesonia, and to her Caligula was more faithful, though from the accounts of ancient writers she appears to have been much older than he, rather homely, and already a mother of three daughters when he first loved her. It is difficult to determine how much truth there is in these reports: Caligula was, it is true, a raving maniac, and his frenzy became more accentuated when under the sway of love—a passion which deranges somewhat even wise men. It is not strange, therefore, that in regard to women he may have been guilty of even greater excesses than he was capable of in his dealings with men. Yet some of these accounts seem a little incredible even when ascribed to a madman. However that may be, Livia Orestilla, Lollia Paulina, Milonia Caesonia are figures without relief, shades and ghosts of empresses, no one of whom had time enough even to occupy the highest post. In vain the people expected that there would appear in the imperial palace a worthy successor to Livia. Caligula, like all madmen, was by nature solitary, and could not live with other human beings: he was to remain alone, a prey to his ravings, which became even stranger and more violent. He now wished to impose upon the empire the worship of his own person, without considering any opposition or local traditions and superstitions. In doing this he did violence not only to the civic and republican sentiment of Italy, which detested this worship of a living man as an ignoble oriental adulation, but also to the religious feeling of the Hebrews, to whom this cult appeared most horrible and idolatrous.

In this way difficulties, dissatisfaction, and sedition arose in all parts of the empire. The extravagances, the wild expenditures, the riotous pleasures, and the cruelties of Caligula increased the discontent and disgust on every hand. We need not take literally all the accounts of his cruelty and violence which ancient writers have transmitted to us,—even Caligula has been blackened,—but it is certain that his government in the last two years of his reign degenerated into a reckless, extravagant, violent, and cruel tyranny. One day the empire awoke in terror to the fact that the imperial family—that family in which the legions, the provinces, and the barbarians saw the keystone of the state—no longer existed; that in the vast imperial palace, empty of women, empty of children, empty of hope, there wandered a raging madman of thirty-one, who divorced a wife every six months, who foolishly wasted the treasure and the blood of his subjects, and who was concerned with no other thought than that of having himself worshiped like a god in flesh and blood by all the empire. A conspiracy was formed in the palace itself, and Caligula was killed.

The senate was much perplexed when it heard of the death of Caligula. What was to be done? The majority was inclined to restore the former republican government by abolishing the imperial authority, and to give back to the senate the supreme direction of the state, which little by little had passed into the hands of the emperor. But many recognized that this return to the ancient form of government would be neither easy nor without danger. Could the senate, neglected, divided, and disregarded as it was, succeed in governing the immense empire? On the other hand, it was not much easier to find an emperor, granted that an emperor was henceforth necessary. In the family of Augustus there was only Claudius, too foolish and ridiculous for them to think of making him the head of the state. It seems that some eminent senator offered his candidacy, but the senate hesitated in perplexity, on the ground that if the authority of the members of the family of Augustus was already so uncertain, so debatable, and so darkly threatened, what would happen to a new emperor, unknown to the legions and the provinces, and unsupported by the glory of his ancestors? While the senate was debating in such uncertainty, the pretorians discovered Claudius in a corner of the imperial palace, where he had been cowering through fear lest he too be killed. Recognizing in him the brother of Germanicus, the pretorians proclaimed him emperor. An act of will is always more powerful than a thousand scruples or hesitations: the senate yielded to the legions, and recognized Claudius the imbecile as emperor.
