Demetrius came before the Senate again and asked at all events to be released as a hostage, since he had been given as a substitute for Antiochus, who was now dead. When his request was not granted he escaped secretly by
boat. As the Syrians received him gladly, he ascended the
throne after having put Lysias to death and the boy with him. He removed Heraclides from office and killed Timarchus, who rebelled and who had administered the government of Babylon badly in other respects. For this he received the surname of Soter (the Protector), which was first bestowed upon him by the Babylonians. When he was firmly established in the kingdom he sent a crown valued at 10,000 pieces of gold to the Romans as the gift of their former hostage, and also delivered up Leptines, the murderer of Octavius. They accepted the crown, but not Leptines, because they intended to hold the Syrians responsible
for that crime. Demetrius took the government of
Cappadocia away from Ariarthes and gave it to Olophernes, who was supposed to be the brother of Ariarthes, receiving 1000 talents therefor. The Romans, however, decided that as brothers both Ariarthes and Olophernes should reign together.
