Tetrachalkon - Antiochos I Theos

Antiochos I of Commagene is unusual among Hellenistic dynasts for having engineered his own theological elevation while still living — his monumental hierothesion at Nemrud Dağ, begun around mid-first century BC, was designed as both tomb and sanctuary where he would be worshipped alongside Zeus-Oromasdes, Apollo-Mithras, and the Greco-Persian pantheon he deliberately fused. The epithet "Theos" on his coinage was not posthumous flattery but a political and religious program he authored himself. Commagene's position between Rome and Parthia made such divine kingship claims strategically useful — projecting power without provoking either neighbor outright.
