Tiberius Claudius Nero (42 BC -37 AD) the second emperor of Rome, son of Tiberius Claudius Nero and Livia, who three years after his birth became the wife of Octavian Augustus, the first emperor of Rome. He was married to Vispania Agrippina, daughter of the commander Marcus Vipsanius Agrippa. Many historians, however, consider that the people on the portrait are Germanicus (15 BC - 9 AD), Tiberius's nephew and adopted son, and Agrippina the Elder ( 14 BC - 33 AD), another daughter of Marcus Vipsanius Agrippa, and the wife of Germanicus. They were the parents of the future Roman emperor Caligula and grandparents of emperor Nero.
