[3] Little is known about Erimena; his name was mentioned in an inscribed bronze shield found at Toprakkale by Hormuzd Rassam in 1880 that is now located in the British Museum.

[6] In later works, N. V. Harutyunyan, relying on new data from the archaeological excavations at Karmir-Blur, indicated that there are no grounds for such claims and that Erimena simply ascended the throne after Sarduri IV.

In the first half of the 20th century, Ivan Meshchaninov suggested that the patronymic of Rusa III does not come from the name of "Erimena", but the nationality "Armenian.”[9][6] This assumption was also expressed by the British historian Richard David Barnett,[10] but later rejected due to the emergence of new data.

[11] This assumption, combined with folk legends, gave rise to the opinion that from 620 BC, the Armenian dynasty already ruled in Urartu.

[8][12][13] Robert Hewsen states that there may be a possible connection between the name of Erimena and the legendary figure Armenak mentioned by Movses Khorenatsi.
