... Antiochus III appointed a scion of the Armenian Orontids, Zariadris (Zareh) to be strategos of Sophene in 200 BC. At this time, in Greater Armenia, the power of the main Orontid dynasty was drawing to a close. The last ruler of this line was Orontes IV (212-200 B.C.). Both he and his brother Mithras, High Priest of the Temple of the Sun and Moon at the city of Armavir, are mentioned in Greek inscriptions discovered there in 1927. One inscription contains an address of High Priest Mithras to his brother King Orontes; another evidently alludes to the king's tragic death. This event was the result of the uprising headed by a local dynast called Artaxias, and evidently instigated from Syria by King Antiochus III. Following this coup, Antiochus appointed Artaxias to be the strategos of Greater Armenia in place of the dead Orontes.
