Julia Drusilla (16 September AD 16 – 10 June AD 38) was a member of the Roman imperial family, the second daughter and fifth child of Germanicus and Agrippina the Elder to survive infancy. She was the favorite sister of Emperor Caligula, who, after her death, had her deified under the name Diva Drusilla Panthea, and named his daughter Julia Drusilla after her. Biography Early life Drusilla was born in Abitarvium, modern day Koblenz, Germany. Besides the future emperor she also had two other brothers, Nero Julius Caesar and Drusus Caesar, as well as two sisters, Julia Livilla and the later empress Agrippina the Younger. She was a great-granddaughter of the Emperor Augustus and empress Livia, grand-niece of the Emperor Tiberius, niece of the Emperor Claudius, and aunt of the Emperor Nero. After the death of her father, Germanicus, she and her siblings were brought back to Rome by their mother and raised with the help of their paternal grandmother, Antonia Minor. Marriages In 33, Drusilla was married to Lucius Cassius Longinus, a friend of the Emperor Tiberius. She and Cassius are not known to have had any children. After Caligula became emperor in 37 he ordered their divorce and married his sister to his friend, Marcus Aemilius Lepidus. During an illness in 37, Caligula changed his will to name Drusilla his heir, making her the first woman to be named heir in a Roman imperial will. This was probably an attempt to continue the Julian line through any children she might have, leaving her husband to rule in the meantime. Caligula recovered however, and in 38, at the age of twenty-one, Drusilla died. Her brother went on to deify her, consecrating her with the title Panthea (all-goddess) and mourning at her public funeral as though he were a widower. Reputation Reportedly, Drusilla was her brother's favorite. There also are rumors that they were lovers, with the two reportedly having been together while they were still underage. If true, that role probably gained her great influence over Caligula. Although the activities between the brother and sister might have been seen as incestuous by their contemporaries, it is not certain whether they were sexual partners. Even if their relationship was not sexual, their close relationship was still very public. Caligula would treat her as if she was his "legal wife" even while she was married. Drusilla earned a rather poor reputation
