The fact of Amr ibn Adi's vassalage to Narses was preserved by the latter in the Paikuli inscription.
Paikuli inscription may be devoid of much historical information because it belongs to the genre of epic literature composed since time immemorial in the ancient Near East.
In the 19th century, when it was visited by several travelers, it consisted of the ruins of a large, square tower that had originally been covered on all sides by stone blocks, some contained inscriptions, but, at the time, lay scattered all around the monument.
In Tabari and sources that follow his work, and also in the Paikuli inscription of Narses, a son of Papak called Shapur is mentioned as his successor, although the text of the inscription of Paikuli in which king Shapur appears is unclear because of long lacunae. Some suggest that Narses in the inscription sought to compare his succession to the throne with that of his grandfather Ardashir, just as Ardashir had succeeded Shapur.

S. Mori contends that the Paikuli inscription is basically relating the traditional Near Eastern story of how a king achieves supremacy with the aid of the gods in the epic form. He also believes that the early Islamic texts, such as al-Tabar? are of little use for the history of the Sasanian period.
