Marcus Vinicius

Marcus Vinicius (c. 5 BC – AD 46) was twice Roman consul and, as husband of Julia Livilla, grandson-in-law (progener) of the emperor Tiberius. He was the son and grandson of two consuls, Publius Vinicius (consul 2 AD) and Marcus Vinicius (consul 19 BC). Life Born in Cales in Campania, Vinicius started his senatorial career as quaestor in AD 20. That same year, Vinicius was requested to take part in the defence of Gnaeus Calpurnius Piso for the murder of Germanicus, but refused. He was present for the trial, as his name appears as one of seven witnesses of the Senatus consultum de Cn. Pisone patre, the Roman Senate's official act concerning Piso's trial and punishment. In 30, Vinicius was appointed to the consulship, which he held with Lucius Cassius Longinus. In the same year, Velleius Paterculus published his Histories, which he dedicated to Vinicius.
