On the Euphrates, modern Gerger, fortified town, founded by Arsames at the beginning of the 2nd cent. BC, and extended by Antiochus I (c. 69-34 BC) as a hierothesion (tomb sanctuary) for his grandfather Samos II and his earlier ancestors. Preserved are a monumental rock relief of Samos II, and important sections of the cultic inscription on the ascent to the castle, which transmits the town's name.
