These troubles and commotions in the East made Antiochus Theos weary of his war with Ptolemy; a treaty of peace was therefore concluded on the following terms: that Antiochus should divorce his former wife Laodice, who was his own sister by the father, marry Berenice, the daughter of Ptolemy, and settle the crown upon the male issue of that marriage. Two years after this marriage Ptolemy Philadelphus died—an event which Antiochus Theos, his son-in-law, no sooner understood than he removed Berenice from his bed, and recalled Laodice, with her children Seleucus Callinicus, and Antiochus Hierax; but Laodice being well acquainted with his fickle temper, and fearing lest he might again abandon her and receive Berenice, resolved to improve the present opportunity and secure the succession to her son, for by the late treaty with Ptolemy, her children were disinherited and the crown settled on the son of Berenice. To effect this design, she caused Antiochus to be poisoned; when she saw him expiring, she ordered him to be privately conveyed away, and one Artemon, who greatly resembled him, as well in features as in the tone of his voice, to be placed in his bed. Artemon acted his part with great dexterity, and personating Antiochus, tenderly recommended his dear Laodice and her children to the lords that visited him. In the name of Antiochus, whom the people believed still alive, orders were issued, enjoining all his subjects to obey his beloved son Seleucus Callinicus, and acknowledge him for their lawful sovereign. The crown being by this infamous contrivance secured to Callinicus, the death of the king was publicly declared, and Callinicus without any opposition ascended the throne. Antiochus Hierax, the other son of Laodice, had at this time the government of the provinces of Asia Minor, where he commanded a considerable body of troops.
Hardly had Seleucus to some extent recovered from the severe defeats inflicted upon him by Ptolemy the “benefactor” during the three years’ war of vengeance, when his younger brother Antiochus, surnamed “the hawk” (Hierax) on account of his rapacity, raised the standard of revolt in conjunction with Mithridates of Pontus, and (Seleucus having been routed by Galatian mercenaries in a terrible battle at Ancyra) made himself master of a large part of Asia Minor, but was forced to pay tribute for it to the hordes of Celtic robbers, who overran the provinces after their victory, ravaging and pillaging with impunity. Not until Seleucus had effected a reconciliation with his brother and made a peace by which he resigned to the latter his dominions in Asia Minor, was he able gradually to reunite the lost or rebellious provinces and to restore tranquillity and order in his kingdom. Both brothers were brave and energetic; but the sanguinary quarrels of their house, and the crimes which were handed down from generation to generation to beget fresh acts of revenge, had imbruted their minds. Alike in vigour, restlessness, and violence, they persecuted each other to the death. Antiochus died a fugitive in a Thracian city under the blows of Celtic assassins, and his royal brother fell in the following year in an unsuccessful fight with Attalus I, the conqueror of the Galatians and ruler of the kingdom of Pergamus.
