Isias

Antiochus I Theos Dikaios Epiphanes Philorhomaios Philhellen (Ancient Greek: Ἀντίοχος ὁ Θεὸς Δίκαιος Ἐπιφανὴς Φιλορωμαῖος Φιλέλλην, meaning "Antiochos, the just, eminent god, friend of Romans and friend of Greeks", c. 86–31 BC, ruled 70–31 BC) was king of the Greco-Iranian kingdom of Commagene and the most famous king of that kingdom.

The ruins of the tomb-sanctuary of Antiochus atop Mount Nemrut in Turkey were added to the UNESCO World Heritage list in 1987. Several sandstone bas reliefs discovered at the site contain some of the oldest known images of two figures shaking hands.
