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
borne two sons to Demetrius, named Seleucus and Antiochus
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.
