Julia the Elder was the only biological child of the emperor Augustus. After Agrippa's death in 12 BC, Augustus made her marry his stepson Tiberius. The marriage was unhappy, and Tiberius withdrew to Rhodes. In 2 BC Augustus exiled Julia to the island of Pandateria for adultery. Around AD 4 she was moved to Rhegium, on the Italian mainland. Julia died in AD 14, some time after Augustus's death. While it is generally agreed by contemporary historians that it was as a result of Tiberius's actions against her, the circumstances of her death are obscure. Dio Cassius indicates Tiberius had a direct hand in her death by imprisoning her until she died either from debility or starvation. Tacitus remarks that upon learning Postumus had been murdered, she succumbed to despair and her health slowly declined. Augustus had explicitly given instructions in his will that she should not be buried in his Mausoleum of Augustus. The main event and its setting are better documented than the precise final moments. Exact last words and private exchanges are not consistently preserved, so those details remain uncertain.
