Antiochus IV Epiphanes
Heliodorus () was a legate of Seleucus IV Philopator c. 187 BC – 175 BC. Some historical sources say that he assassinated Seleucus and seized the throne for himself, before Antiochus IV Epiphanes, the brother of the late king, with the help of the Pergamon monarch, Eumenes II, recovered it.
