When obeying the summons of Antony, Herod had committed the government to his uncle Joseph, who was also his brother-in-law, having wedded Salome, the sister of Herod. His mad jealousy had prompted him to direct that, in case of his condemnation, Mariamme was to be killed, that she might not become the wife of another. Unfortunately, Joseph told this to Mariamme, to show how much she was loved. But on the return of Herod, the infamous Salome accused her old husband of impropriety with Mariamme. When it appeared that Joseph had told the Queen of his commission, Herod, regarding it as confirming his sister's charge, ordered him to be executed, without even a hearing. External complications of the gravest kind now supervened. Herod had to cede to Cleopatra the districts of Phoenice and Philistia, and that of Jericho with its rich balsam plantations. Then the dissensions between Antony and Octavius involved him, in the cause of the former, in a war with Arabia, whose king had failed to pay tribute to Cleopatra. Herod was victorious; but he had now to reckon with another master. The battle of Actium [587] decided the fate on Antony, and Herod had to make his peace with Octavius. Happily, he was able to do good service to the new cause, ere presenting himself before Augustus. But, in order to be secure from all possible rivals, he had the aged Hyrcanus II. executed, on pretence of intrigues with the Arabs. Herod was successful with Augustus; and when, in the following summer, he furnished him supplies on his march to Egypt, he was rewarded by a substantial addition of territory.
When about to appear before Augustus, Herod had entrusted to one Soemus the charge of Mariamme, with the same fatal directions as formerly to Joseph. Again Mariamme learnt the secret; again the old calumnies were raised - this time not only by Salome, but also by Kypros, Herod's mother; and again Herod imagined he had found corroborative evidence. Soemus was slain without a hearing, and the beautiful Mariamme executed after a mock trail. The most fearful paroxysm of remorse, passion, and longing for his murdered wife now seized the tyrant, and brought him to the brink of the grave. Alexandra, the mother of Mariamme, deemed the moment favorable for her plots - but she was discovered, and executed. Of the Maccabean race there now remained only distant members, the sons of Babas, who had found an asylum with Costobarus, the Governor of Idumæa, who had wedded Salome after the death of her first husband. Tired of him, as she had been of Joseph, Salome denounced her second husband; and Costobarus, as well as the sons of Babas, fell victims to Herod. Thus perished the family of the Maccabees.
The hand of the maddened tyrant was next turned against his own family. Of his ten wives, we mention only those whose children occupy a place in this history. The son of Doris was Antipater; those of the Maccabean Mariamme, Alexander and Aristobulus; another Mariamme, whose father Herod had made High-Priest, bore him a son named Herod (a name which other of the sons shared); Malthake, a Samaritan, was the mother of Archelaus and Herod Antipas; and, lastly, Cleopatra of Jerusalem bore Philip. The sons of the Maccabean princess, as heirs presumptive, were sent to Rome for their education. On this occasion Herod received, as reward for many services, the country east of the Jordan, and was allowed to appoint his still remaining brother, Pheroras, Tetrarch of Peræa. On their return from Rome the young princes were married: Alexander to a daughter of the King of Cappadocia, and Aristobulus to his cousin Berenice, the daughter of Salome. But neither kinship, nor the yet nearer relation in which Aristobulus now stood to her, could extinguish the hatred of Salome towards the dead Maccabean princess or her children. Nor did the young princes, in their pride of descent, disguise their feelings towards the house of their father. At first, Herod gave not heed to the denunciations of his sister. Presently he yielded to vague apprehensions. As a first step, Antipater, the son of Doris, was recalled from exile, and sent to Rome for education. So the breach became open; and Herod took his sons to Italy, to lay formal accusation against them before Augustus. The wise counsels of the Emperor restored peace for a time. But Antipater now returned to Palestine, and joined his calumnies to those of Salome. Once more the King of Cappadocia succeeded in reconciling Herod and his sons. But in the end the intrigues of Salome, Antipater, and of an infamous foreigner who had made his way at Court, prevailed. Alexander and Aristobulus were imprisoned, and an accusation of high treason laid against them before the Emperor. Augustus gave Herod full powers, but advised the convocation of a mixed tribunal of Jews and Romans to try the case. As might have been expected, the two princes were condemned to death, and when some old soldiers ventured to intercede for them, 300 of the supposed adherents of the cause were cut down, and the two princes strangled in prison. This happened in Samaria, where, thirty years before, Herod had wedded their ill-fated mother.
