This splendid royal marriage probably gave Livilla grand aspirations for her future, perhaps at the expense of the ambition of Augustus' granddaughters, Agrippina the Elder and Julia the Younger.

Pisone patre[4] indicates that she was held in the highest esteem by her uncle and father-in-law, Tiberius, and by her grandmother Livia Drusilla.

[5] According to Tacitus, she felt resentment and jealousy against her sister-in-law Agrippina the Elder, the wife of her brother Germanicus, to whom she was unfavourably compared.

Suetonius reports that she despised her younger brother Claudius; having heard he would one day become Emperor, she deplored publicly such a fate for the Roman people.

According to Tacitus, Suetonius, and Cassius Dio, Sejanus had poisoned Drusus, not only because he feared the wrath of the future Emperor but also because he had designs on the supreme power, and aimed at removing a potential competitor, with Livilla as his accomplice.

In the same year, the Emperor received evidence from Antonia Minor, Livilla's mother and his sister-in-law, that Sejanus planned to overthrow him.

A bloody purge then erupted in Rome with most of Sejanus' family (including his children) and followers sharing his fate.

According to Cassius Dio, before her death, she addressed a letter to Tiberius, accusing Sejanus and Livilla of having poisoned Drusus.

[8]] Drusus' cupbearer Lygdus and Livilla's physician Eudemus were questioned and under torture confirmed Apicata's accusation.

According to Cassius Dio, Tiberius handed Livilla over to her mother, Antonia Minor, who locked her up in a room and starved her to death.

The physiognomy is close but not identical to portraits of Antonia Minor, Livilla's mother and some replicas seem to bear the marks of voluntary damage (that one would expect from a damnatio memoriae).
