Arsameia

[1] The Greek word hierothesion (ἱεροθέσιον) is term for the holy burial areas of those belonging to the royal house, and is only known from Commagene.

Apart from the Hierothesion which Antiochos himself built on Nemrut Dağı, and the second one on Karakuş which his son Mithridates II built for the female members of the royal house, a third is to be found in Arsameia, the burial site and the associated cultic area for Antiochus' father Mithridates.

The function of this is not clear; Dörner took it to be a temple to Mithras, while other archaeologists conjecture that it could be the burial site of Mithridates.

In the lower part of the inscribed wall a walkway begins that goes steeply up the rock and then suddenly ends after 158 metres.

It shows one of the two kings, either Antiochos or Mithridates shaking hands with a naked Herakles, recognizable from his club.

On the basis of fragments of sculpture Dörner takes it that this is where the mausoleum of Mithridates stood, decorated with statues.

In its interior are found building and restoration inscriptions from the sultans Qala'un (1279–90), Al-Ashraf Khalil (1290–93) and al-Nasir Muhammad (1293–1341).

It was still being used for communications as late as the 13th century when the Sultan Qala'un was seeking information about the troop movements of the hostile Ilkhanate before the Second Battle of Homs.

[2] To the west of the two mountains of Yenikale and Eskikale Dörner and his colleague Wilhelm Winkelmann discovered an area of iron smelting, the first in Commagene.
