112), also transliterated Rʻuṯassor,[5] Rʻūṯ’assor[6] or Rʻūṯassor,[4] was a local Assyrian king or city-lord in the early 2nd century AD, ruling the city of Assur under the suzerainty of the Parthian Empire.

[2] Though the stele, dated to the 424th year of the Seleucid calendar (112/113 AD),[6] does not give Rʻuth-Assor a specific title,[6] he is generally regarded as one of the city's lords by modern historians and would as such have been styled maryo[17] or māryā[18] ("master") of Assur.

[2] Though the inscription on the stele is written in Aramaic (and not Akkadian)[a] and R'uth-Assor is depicted with a Parthian-style trouser suit, rather than the ancient royal garbs,[1] the stele is framed in an identical manner to the stelae of the old kings, the pose is similar, and he is depicted in veneration of the moon and the sun, an ever-present motif in the stelae of the ancient kings.

[4][21] The difference in the name of Rʻuth-Assor's father can likely be explained by ʻBenna ("of the god") being a shortened form or nickname of Banḇūʾeḥdeṯ ("I fight with Nabu").

[6] The inscriptions also attest to Nbudayyan having a son, Awidʾallayy (ʿAwīḏʾallayy, "protection-seeker of Al-Lat"), and daughter, Maleka (Malekā, "queen"), the fitst with an Arabic name.

[26] The line of local rulers at Assur under Parthian suzerainty came to an end at the latest with the conquests of the Sasanian Empire in the region, c. 240-250 AD,[27] whereafter the Ashur temple was destroyed again and the most of the city's people were dispersed.
