Ceasar Germanicus was a distinguished Roman. The son of NeroClaudiusDrusus and the younger Antonia, a niece of Augustus, he was born in 15 BC and died in 19 AD. He was adopted by Tiberius, his paternal uncle, and married Agrippina, the granddaughter of Augustus. When Augustus died, in 14 AD, Germanicus was invited by the rebellious legions on the Rhine to assume the sovereignty, but refused, and quelled the revolt. He then crossed the Rhine, surprised and defeated the Marsi with great slaughter. Next year a campaign against the Catti and the Germans, led by Arminius, resulted in a series of victories. The following year he again made his way into Germany, defeated the Cherusci twice, and made an incursion into the country of the Marsi. Tiberius now became jealous of the glory of Germanicus, called him home under pretence of granting him a triumph, then, to get rid of him, sent him into the East to compose the disturbances in Armenia and Cappadocia. This he performed in 18 AD, visited Egypt the following year, and died on his return to Syria under some suspicion of having been poisoned by Cn. Piso, the governor of Syria.
