Synopsis: Cleopatra Thea marries Demetrius II’s brother, Antiochus VII, becoming the simultaneous queen of two Seleucid kings. While Antiochus crushes Tryphon’s revolt and recovers former Seleucid territories, Demetrius is defeated by Mithridates and imprisoned in distant Hyrcania.
“But as Antiochus, the brother of Demetrius (II) who was called Soter, was not admitted by any of the cities on account of Tryphon, Cleopatra sent to him, and invited him to marry her, and to take the kingdom. The reasons why she made this invitation were these: That her friends persuaded her to it, and that she was afraid for herself, in case some of the people of Seleucia (Pieria) should deliver up the city to Tryphon. As Antiochus was now come to Seleucia, and his forces increased every day, he marched to fight Tryphon; and having beaten him in battle, he ejected him out of Upper Syria into Phoenicia, and pursued him thither, and besieged him in Dora which was a fortress hard to be taken, whither he had fled.” – Josephus, The Antiquities of the Jews, Book XIII, Chapter 7
“Antiochus well remembered that his father had been hated for his arrogance and his brother despised for his idleness. To avoid falling into the same vices himself, he married Cleopatra, his brother’s widow, and took vigorous action against the cities which had defected at the start of his brother’s reign. He subdued them and added them once more to the territory of his kingdom.” – Justin, Epitome of the Philippic History of Pompeius Trogus, 36.1.9
