[1] Coins, reliefs and Babylonian astronomical diaries label Gotarzes as the son and heir of Mithridates II (r. 124–91 BC).

[5] Gotarzes continued his father's policy by using their vassal, the Artaxiad king of Armenia, Tigranes the Great (r. 95–55 BC), as their representative in their efforts to extend their influence to Syria and Cappadocia.

[12] Under Gotarzes I and Orodes I, Babylonian scholars notably followed wrote cuneiform records in the same method that had been done in era of the Iranian Achaemenid Empire.

[4] According to M. Rahim Shayegan and Alberto M. Simonetta, Gotarzes died in 80 BC and was succeeded by Orodes I.

"Rahim M. Shayegan (2011), has suggested, contrary to other scholars, that the rock relief was not constructed during the reign of Mithridates II, but during that of his son and successor Gotarzes, perhaps as an attempt to stress the legitimacy of his sovereignty by portraying the prestigious status of himself and his officers during Mithridates II's kingship.
