Synopsis: Gaius Julius Sohaemus is compelled to help the Romans conquer Commagene.
“Petus…fell upon Commagene before Antiochus and his people had the least expectation of his coming. He had with him the tenth legion, and also some cohorts and troops of horsemen. These kings also came to his assistance: Aristibulus, king of the country called Chalcidene, and Sohaemus, who was called King of Emesa. Nor was there any opposition made to his forces when they entered the kingdom, for no one of that country would so much as lift up his hand against them.” – Josephus, The Jewish War, Book VII, Chapter 7
