A Daughter of the Julio-Claudians
Julia Drusilla was born in 16 AD into a prestigious family, the Julio-Claudians, within a court where family alliances were as important as battles. The daughter of Germanicus, a hero of the Roman armies, and Agrippina the Elder, a direct descendant of Augustus, Drusilla could have grown up under promising auspices. But the mysterious death of Germanicus in 19 AD and the power struggles that followed plunged her family into unprecedented turmoil.
Caius, her elder brother, the future emperor known as Caligula, was marked by these years of chaos. Coming from a family destroyed by the persecutions of Emperor Tiberius, Caligula developed a twisted vision of love, where possession became synonymous with absolute control. Ancient authors later presented him as projecting onto Drusilla emotions that exceeded the bounds of brotherhood.
The Accusation That Darkened the Court
According to the hostile accounts of Suetonius and Cassius Dio, Caligula allegedly took his sister as his mistress when she was still very young. Such claims must be handled with caution: Roman political writing often used sexual scandal to blacken the reputation of unpopular rulers. Yet the persistence of the accusation reveals how disturbing Caligula's attachment to Drusilla appeared to later tradition.
Drusilla was vulnerable in a family where kinship was constantly bent to the political and personal desires of men. Caligula, raised in an atmosphere of suspicion and violence at the court of Tiberius, is described by the sources as possessive and domineering toward her. To him, Drusilla was not simply a sister: she became, in hostile memory, an object of desire, a sacred figure, an extension of himself.
Marriages and Possession
For Caligula, sharing Drusilla with another man was inconceivable, at least in the portrait drawn by hostile ancient writers. Yet, in an attempt to give his sister a respectable position, she was married young to Lucius Cassius Longinus, a man of senatorial rank. But this marriage was quickly perceived by Caligula as a threat. How could he tolerate that the one he considered his property be tied to another?
As soon as he ascended to the throne in 37 AD, Caligula used his power to take his sister back from her husband. Longinus was removed from this role, and sources connect his later downfall to the emperor's hostility. This brutal political gesture shows not only Caligula's absolute authority but also the depth of his reported obsession with Drusilla.
To hide or contain this relationship from the public, Caligula then married her to a man from his entourage, Marcus Aemilius Lepidus. However, this marriage may have served as a facade within the logic of the imperial court. Ancient narratives suggest that Drusilla remained the woman Caligula placed above all others. Imperial banquets were an opportunity for the emperor to display his affection for her with an insistence that exceeded Roman conventions. He ensured that no woman, not even his official wife, could rival Drusilla in the imperial court.
The Silent Problem of Consent
For Caligula, Drusilla was much more than a mistress in the scandalous tradition. She was a living icon, whom he adored beyond reason. In Suetonius' accounts, Caligula appears as a man unable to bear the slightest distance between them. He often referred to her as the "second Venus," embodying divine beauty and purity.
The emperor demanded that she be treated with a deference that surpassed that of any other member of the imperial family. He placed her near him during official ceremonies, gave her a privileged position, and ensured that her rank in the imperial hierarchy was uncontested. This veneration took a macabre turn with her premature death.
The question of Drusilla's consent in her alleged relationship with her brother Caligula is impossible to determine with certainty. Ancient sources, biased and focused on criticizing Caligula, provide no direct access to Drusilla's thoughts. In the context of the Roman Empire, where women of the imperial family were often used as political instruments, Drusilla would have had very little room for maneuver.
As the sister of an all-powerful emperor, refusing his desires would have been almost impossible, given the high personal and familial risks. Although some sources describe Drusilla as close to and influential with Caligula, this does not mean she was willing in this alleged relationship. This closeness could have been exaggerated or misinterpreted to further blacken Caligula's portrait.
Moreover, the accusation of incest was a common weapon in criticisms of unpopular emperors and could have been used to demonize his reign. In the end, Drusilla remains a silent figure in history, deprived of any opportunity to express her views on her fate. Everything suggests that she was a victim of the brutal power dynamics and patriarchal structures of her time, without us truly knowing the nature of her feelings about this relationship.
Death and Deification
In 38 AD, barely a year after her brother's accession to the throne, Drusilla suddenly died at the age of 22. The exact causes of her death remain unclear. Some suggest illness; others raise the possibility of poisoning, perhaps orchestrated by political enemies seeking to weaken Caligula. Whatever the reason, her disappearance plunged the emperor into boundless distress.
Refusing to accept this loss, Caligula ordered a national mourning of unprecedented scale. The Senate and the people were forced to mourn Drusilla as if she were an empress. But the most striking act was undoubtedly the deification of his sister. Under the name Diva Drusilla, she was assimilated to Venus, the goddess of love and beauty.
Caligula, in an ultimate act of devotion, ordered that statues representing Drusilla be erected throughout the Empire. Priests were appointed to serve her cult, and sacrifices were offered to her. Some accounts even report that the emperor claimed to communicate with her from beyond the grave, ensuring that her spirit continued to watch over him. This obsession with his deceased sister reveals the mental fragility of a man unable to cope with loss.
A Victim and a Symbol
The cult of Drusilla was not well received by all. The Senate, already irritated by Caligula's extravagances, considered this adoration an insult to Roman traditions. As for the people, accustomed to the excesses of the elite, they were nonetheless shocked by the scandal attached to this relationship.
But Drusilla, in many ways, remains an ambivalent figure. Although she benefited from the privileges and veneration of her brother, she was nonetheless a victim. A prisoner of the desires of a man who considered her his possession, her role within the imperial court left her little room to express her own ambitions or desires.
Her story is therefore not only the story of Caligula's excess. It is also the story of a woman whose voice disappeared behind accusation, propaganda, dynastic violence, and male power. Drusilla was turned into scandal, then into a goddess, but never allowed to become fully human in the sources that preserved her name.
