Bronze bust of Agrippa Postumus (4 CE, Louvre). Agrippa was called Postumus because he was born after the death of his father, Marcus Vipsanius Agrippa, the youngest grandson of Augustus. Augustus did not favor him as he had his older brothers, and several ancient sources report that he was physically strong but wild and reckless. In 4 CE, after the death of Gaius Caesar, Augustus finally adopted Agrippa Postumus along with Tiberius, but in less than two year the emperor had disinherited and banished Agrippa for reasons that are not known to modern historians. Agrippa Postumus was killed by a centurion immediately after the death of Augustus in 14 CE on orders from Rome, but it is impossible to prove who actually issued the orders.
