Vipsania Agrippina
Vipsania Agrippina (36 BC – 20 AD) was the first wife of the Emperor Tiberius.
She was the daughter of Marcus Vipsanius Agrippa and Pomponia Caecilia Attica, thus a granddaughter of Titus Pomponius Atticus.
By marriage, she was also a great-niece to Quintus Tullius Cicero.
She was betrothed by Augustus and her father to Tiberius, the stepson of Augustus, before her first birthday.
They were married around 19 BC.
Their son Drusus Julius Caesar was born in 14 BC.
Her father died in March 12 BC while married to his third wife Julia the Elder, the daughter of Augustus.
Augustus forced Tiberius to divorce Vipsania and marry Julia, despite his love for the former and disapproval of the latter.
At the time of their divorce, Vipsania was pregnant with a second child, who did not survive.
Tiberius divorced Vipsania against his will in 11 BC ("non sine magno angore animinot without great mental anguish"], according to Suetonius) and never ceased to rue his action.
On one occasion Tiberius caught sight of Vipsania and followed her with an intent and tearful gaze.
Precautions were taken to avoid further embarrassing meetings with her.
In 11 BC she married Gaius Asinius Gallus Saloninus, a Senator and son of the famous orator Gaius Asinius Pollio.
They had at least six sons.
Vipsania Agrippina died in AD 20, a few days after the ovation of her son Drusus, which took place on 28 May.
Tiberius hated Gallus, not least because Gallus claimed that Drusus was his own son.
In 30, at Tiberius' instigation, the Senate was to declare Gallus a public enemy.
He died in prison in 33, of starvation.
