I have also spoken of Demetrius, his successor, who B.C.162 seq. had been a hostage in Rome and who escaped and became king. He was also called Soter by the Syrians, the next who bore that title after the son of Seleucus Nicator. Against him a certain Alexander took up arms, falsely pretending to be of the family of the Seleucidae, to whom Ptolemy, king of Egypt, gave aid because he hated Demetrius. The latter was deprived of his kingdom by this means and died. His son, Demetrius, drove out Alexander. For his victory over this bastard of the family he was surnamed Nicator by the Syrians, the next who bore that title after Seleucus. Following the example of Seleucus he made an expedition against the Parthians. He was taken prisoner by them and lived in the palace of King Phraates, who gave him his sister, Rhodoguna, in marriage.

While the country was without a government Diodotus, a slave of the royal house, placed on the throne a young boy named Alexander, a son of Alexander the Bastard and of Ptolemy’s daughter. Afterward he put the boy to death and undertook the government himself and assumed the name of Trypho. But Antiochus, the brother of the captive Demetrius, learning in Rhodes of his captivity, came home and, with great difficulty, put Trypho to death. Then he marched with an army against Phraates and demanded his brother. Phraates was afraid of him and sent Demetrius back. Antiochus nevertheless fought with the Parthians, was beaten, and committed suicide. When Demetrius returned to his kingdom he was killed by the craft of his wife, Cleopatra, who was jealous on account of his marriage with Rhodoguna, for which reason also she had previously married his brother Antiochus. She had Y.R. 592 seq. borne two sons to Demetrius, named Seleucus and Antiochus B.C.162 seq. Grypus (the Hook Nosed); and to Antiochus one son, named Antiochus Cyzicenus. She had sent Grypus to Athens and Cyzicenus to Cyzicus to be educated.
