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.
