A new life of adventure now commenced in Rome for Agrippa. He was met on the Isle of Capri by the Emperor Tiberius, who, in remembrance of Agrippa's close connection with the son he had lost, received him most kindly. But upon hearing of the enormous sum of money that Agrippa still owed to the Roman treasury, Tiberius allowed him to fall into disgrace. He was saved, however, by his patroness Antonia, the sister-in-law of the emperor, who maintained a friendly remembrance of Agrippa's mother Berenice. By her mediation he was raised to new honors, and became the trusted friend of the heir to the throne, Caius Caligula. But, as though Agrippa were destined to be the toy of every caprice of fortune, he was soon torn from his intercourse with the future emperor and thrown into prison. In order to flatter Caligula, Agrippa once expressed the wish, "Would that Tiberius would soon expire and leave his throne to one worthier of it." This was repeated by a slave to the emperor, and Agrippa expiated his heedlessness by an imprisonment of six months, from which the death of Tiberius at last set him free (37). With the accession to the throne of his friend and patron, Caligula, his star rose upon the horizon. When the young emperor opened the prison-door to Agrippa he presented him with a golden chain, in exchange for the iron one that he had been forced to wear on his account, and placed the royal diadem upon his head, giving him the principality of Philip, that had fallen to the Empire of Rome. By decree of the Roman Senate he also received the title of Prætor. So devoted was Caligula to Agrippa that, during the first year of his reign, the Roman emperor would not hear of his quitting Rome, and when at length Agrippa was permitted to take possession of his own kingdom, he had to give his solemn promise that he would soon return to his imperial friend. When Agrippa made his entry into Judæa as monarch and favorite of the Roman emperor, poor and deeply in debt though he had been when he left it, his wonderful change of fortune excited the envy of his sister Herodias. Stung by ambition, she implored of her husband also to repair to Rome and to obtain from the generous young emperor at least another kingdom. Once more the painful want of family affection, common to all the Herodians, was brought to light in all its baseness. Alarmed that Antipas might succeed in winning Caligula's favor, or indignant at the envious feelings betrayed by his sister, Agrippa accused Antipas before the emperor of treachery to the Roman Empire. The unfortunate Antipas was instantly deprived of his principality and banished to Lyons, whither he was followed by his faithful and true-hearted wife. Herod's last son, Herod Antipas, and his granddaughter, Herodias, died in exile. Agrippa, by imperial favor, became the heir of his brother-in-law, and the provinces of Galilee and Peræa were added to his other possessions.
