standard-bearer of the first legion in Germany at the accession of Tiberius, A. D. 14. When Munatius Plancus arrived in the camp of Gennanicus in Germany, as the ambassador of the senate, the rebellious soldiers would have murdered him while he was embracing as a suppliant the sacred standards, had not Calpurnius checked the violence of the soldiers. (Tac. Ann. 1.39.)
