It is likely that Napir-Asu corresponds to the daughter of the Babylonian Burnaburiash (perhaps the king Burna-Buraish II) married by Untash-Napirisha.

A statue of the god Immiriya in Chogha Zanbil was dedicated by Napir-Asu's husband Untash-Napirisha to his father-in-law Burnaburiash.

[5] Historians Esfandyar Rahmati Kia and Kolsoum Ghazanfari have argued that Napir-Asu held some power in her own right.

[7] In 1903 archaeologist Jacques de Morgan, working as part of the Délégation scientifique française en Perse, discovered a 130cm high statue, made of a bronze core, covered by a layer of copper, with cast and chased decoration, weighing 1750 kg.

Once the copper was cooled, the clay core was removed and layers of bronze were poured into the hollow of the body.

On the fringed skirt of this statue, the names of the queen and the great gods of Susa are engraved in Elamite cuneiform.
