Napirisha is believed to have originated from Anshan, entering Susa as a dynastic god following the dynasty of Shimashki, especially since Kiririsha, who is generally viewed to be the consort of Napirisha, is the tutelary goddess of Liyan. It is generally believed that Napirisha (and
Kiririsha) were Anshanite gods. and that Napirisha represents Anshan as its main god, similar to Inshushinak with Susa. The earliest attestation of Napirisha is in a tablet likely dating to the early Sukkalmah dynasty, where an oath was taken in the name of the god. However, if the dating of some of the newly translated
Linear Elamite inscriptions are accurate, then the earliest attestation of Napirisha is during the
Shimashki dynasty, during the reign of
Kindattu. Desset more recently suggested that Napirisha might be tied directly to the Shimashki dynasty. However, Grillot-Susini claims that Napirisha and Kiririsha were present side-by-side on a scribal tablet dating to before the Sukkalmah dynasty in Susa. In the Šurpu incantation series, Napirisha is identified with
Ea. It is thus assumed that Napirisha may have had similar traits and characteristics as Ea, such as being associated with subterranean waters. Alongside this, Napirisha is also sometimes assumed to also be an underworld god, in a similar vein to Inshushinak,
Lagamal and Kiririsha. Glassner suggests that an inscription on a gunagi vessel that invoked Napirisha describing burnt offerings for Amma-tedak for guaranteeing a line of succession for Ebarat represents offerings to the deceased ruler to lead the now deceased Amma-tedak on the way to Napirisha in a similar vein to a later inscription by
Shilhak-Inshushinak, which is commonly interpreted as asking the deceased ruler Kuk-Kirwash to be an intercessor on the way to Inshushinak. In the god list Anshar=Anum, Napirisha is listed as a name or equivalent of Anu and possibly also as one of the other names for Shamash. The identification of the god on the Kurungum relief, and by extension the motif of a god on a serpent throne with streaming waters, is currently still a subject of debate. Some scholars identify the god on the relief as Napirisha, while others with Inshushinak. French archaeologist
Pierre de Miroschedji identified the figure as Inshushinak, but recognized that the identification with Napirisha would be more convenient. Potts had suggested that it was both Napirisha and Inshushinak, especially on the basis that both gods were identified with Ea. Álvarez-Mon suggests that the two gods were syncretized and shared responsibilities, and thus the relief may have depicted them as one, or perhaps key attributes were merged into a single “great god” (dGAL). De Graef also suggests that both deities are depicted as one in a seal dating to the sukkalmah period that depicts a god on a serpent throne with water flowing from the hand following her retranslation of the sea. == Relationship with other deities ==
