The ancient Kingdom of Commagene was an Armenian kingdom, which is evidenced by a wide range of ancient artifacts.

For example, on the below images of coins depicting Antiochus I Theos of Commagene, the king wears an Armenian tiara with the coat of arms of the Armenian Artaxiad dynasty, just like the coins portraying Tigran II the Great.

Now, compare these coins with the coins of Tigran the Great depicting the coat of arms of the Artaxiad dynasty.

Below, you can see the coins of the kings of the Artaxiad dynasty with the image of Vahagn, testifying to the dynasty’s closeness with the deity.

Another set of coins of the Armenian Kingdom of Commagene demonstrates more resemblance. Below are the coins of Epiphanes and Callinicus, sons of Antiochus IV of Commagene, wearing an Armenian tiara.
