Antiochus IV of Kommagene was made king of Kommagene by Caligula, who deposed him almost immediately. Restored by Claudius in 41, he reigned until 72 as an ally of Rome against Parthia. That year he was deposed on suspicion of treason and retired Rome. Several of his coins are extant.
The small kingdom of Kommagene (lat Commagene) in northern ancient Syria (modern south-central Turkey) bounded by Cilicia on the west and Cappadocia on the north arose in 162 BC, where the governor Ptolemy broke free from the disintegrating Seleucid Empire.
Kommagene is famous for its sanctuary located in Nemrud Mountain (Nemrud Dagi), an enormous complex on a mountain-top founded by Antiochus Theos featuring giant statues of the king (whose epithet means God), surrounded by gods.
The location of Antiochus' tomb is one of the mysteries of archeology and recent research has revealed that on the peak of Nemrud Mountain close to the mausoleum there are some cavities that could hold the tomb of the king.
