Agrippa, Marcius
a man of the lowest origin, was appointed by Macrinus in B. C. 217, first to the government of Pannonia and afterwards to that of Dacia. (Dion. Cass. 78.13.) He seems to be the same person as the Marcius Agrippa, admiral of the fleet, who is mentioned by Spartianus as privy to the death of Antoninus Caracallus. (Anton. Car. 6.)
