Agrippa in Harpers Dictionary of Classical Antiquities

Agrippa, Marcus Vipsanius. A Roman general, who was born in B.C. 63, of an obscure family; studied with young Octavius (afterwards the emperor Augustus) at Apollonia, in Illyria, and upon the murder of Caesar, in B.C. 44, was one of the friends of Augustus who advised him to proceed immediately to Rome. In the civil wars which followed, and which terminated in giving Augustus the sovereignty of the Roman world, Agrippa took an active part; and his military abilities contributed greatly to that result. He commanded the fleet of Augustus at the battle of Actium in B.C. 31. He was thrice consul, and in his third consulship, in B.C. 27, he built the Pantheon. In the year 21 he married Iulia, daughter of Augustus. He continued to be employed in various military commands till his death in B.C. 12. By his first wife, Pomponia, Agrippa had Vipsania, married to Tiberius, the successor of Augustus; and by Iulia he had two daughters, Iulia and Agrippina, and three sons, Caesar, Lucius Caesar, and Agrippa Postumus. The last was banished by Augustus to the island of Planasia, and was put to death by Tiberius, A.D. 14. See portrait on p. 16.
