The earliest
Elamite source mentioning Inshushinak is the treaty between
Naram-Sin of Akkad and an Elamite ruler, possibly
Khita of
Awan. This identification is commonly cited in modern literature, though it ultimately remains uncertain, and it is not clear if the Elamite signatory, who is left nameless, hailed from Awan at all. While Inshushinak is only listed sixth among the gods invoked as its divine witnesses, after
Pinikir,
Humban, Amba, Zit and
Nahhunte, he appears multiple times through the document, with four certain references and further five tentatively restored ones. Wouter Henkelman on this basis suggests that it is not impossible that the text reflects the cultural milieu of
Susa, rather than Awan.
Susa The last king of the
Awan dynasty, Puzur-Inshushinak (reigned 2100 BCE), instated daily offerings to Inshushinak in Susa, which constitutes the oldest known reference to such a practice in sources from Elam. It is possible that the meat of the sheep offered to him at dawn and dusk was then consumed by religious personnel. The inscription commemorating this event invokes Inshushinak alongside
Shamash,
Enlil,
Enki,
Ishtar,
Sin,
Ninhursag,
Narunte and "the totality of the gods" in a curse formula. Most likely multiple temples dedicated to Inshushinak existed in Susa. Most likely they stood near the acropolis of Susa, as indicated by the discovery of numerous inscribed bricks and three houses of worship, one of which is known to have been dedicated to Inshushinak, during excavations. It is located in the southeast of this area. Textual sources indicate of the houses of worship dedicated to him bore the ceremonial
Sumerian name Ekikununna ("
house, princely pure place") or Ekikuanna ("house, pure place of heaven"). According to Françoise Grillot-Susini both of these names might be attempts at creating a Sumerian writing of the Elamite term
kukunnum. It has been proposed that it referred to the temple on the top of a
ziggurat, possibly with funerary connotations. It was rebuilt by Indattu-Inshushinak and Indattu II from the
Shimashki dynasty. It is agreed that it should be considered separate from the "old temple" (É.GAR8 GIBIL) restored by the
sukkalmah Kuk-Kirwaš, but it remains uncertain if the latter can also be distinguished from the temples mentioned in inscriptions of Puzur-Inshushinak and
Shulgi of
Ur. Another of the temples of Inshushinak was referred to as
haštu, "tomb". Presumably this naming choice reflected the worship of Inshushinak's underworld aspect. It has been argued that the É.DÙ.A (reading uncertain), a structure mentioned in an inscription on a stela of
Tepti-ahar according to which its six guards were supposed to provide specific commodities during "the festivals of
abu, the four days of
tašritu, the feast of the deity Kirwašir, and the day of the new moon" might have been a temple or another "edifice with a funerary function" dedicated to Inshushinak, though the term has also been alternatively interpreted as referring to a tomb or as a vague designation for a construction project. The structure was restored by Inshushinak-shar-Ilani in the Middle Elamite period. Inshushinak could also be venerated in sanctuaries known as
siyan husame, "temple in the grove", which as indicated by their name were located within
sacred groves, well attested in Elamite sources. However, they are not attested in sources from Susa predating the Middle Elamite period. They might have played a role in a funerary cult. It has been suggested that this might have been true for the
siyan husame in general, but while multiple deities for whom such structures are attested, including Inshushinak,
Ishmekarab,
Lagamal,
Kiririsha and possibly
Napirisha, were associated with the underworld, others, like
Manzat,
Simut and Suhsipa, lacked such a connection. Furthermore, the proposed identification between
siyan husame and
haštu, in the past used to support this proposal, is no longer accepted, as they are listed as two separate types of structures in the text EKI 48. A type of monumental gates,
hiel, could be dedicated to Inshushinak too, and might have represented the entrance to the underworld. However, this conclusion is not certain, as they could be dedicated to various deities, not all of whom have been conclusively proven to be connected to beliefs pertaining to death and the afterlife.
Other cities A stele of
Shilhak-Inshushinak discovered in the temple of Inshushinak located at the acropole of Susa enumerates twenty
siyan husame restored by this king, most of which were dedicated to Inshushinak, including these located in Tēttu, Ša Attata-mitik, Ekallat, Bīt Turni (restoration partially uncertain), Ša Attata-ekal-likrup, Marrut, Ša Hantallak and possibly Perraperra. Most of these toponyms are otherwise unattested, and it has been argued that they must have been located near the city. However, Wouter Henkelman argues that sanctuaries of Inshushinak might have not been located only in the proximity of Susa, with
siyan husame dedicated to him possibly serving as "markers of royal power" in other parts of Elam. A
ziggurat dedicated to Inshushinak existed in
Chogha Zanbil (Al-Untash-Napirisha), a city originally established by
Untash-Napirisha. In inscriptions from this site he is identified as the "lord of the dead in the
siyan kuk", a term referring to the local temple complex. A sanctuary dedicated jointly to him and Napirisha was located on top of it. He also had a sanctuary in this location referred to with the term
likrin, a
hapax legomenon whose translation remains uncertain. Attestations of temples of Inshushinak are largely limited to texts from Susa and Chogha Zanbil. However, an inscription of Untash-Napirisha from Tappeh Deylam preserved in six copies also mentions the construction of a sanctuary dedicated to him, and Tepti. Near the end of the Middle Elamite period, around 1125 BCE, a temple dedicated jointly to him, Napirisha,
Kiririsha and
Simut was built in Anshan by king
Hutelutush-Inshushinak. It was designated by the otherwise unattested term,
siyan tarin, "temple of the alliance", though it is not known if this name refers to a secular alliance, to an alliance between worshipers and deities, or to one between the four deities worshiped together in it. However, it is assumed that Inshushinak was not commonly venerated in Anshan, and he is otherwise only attested there in a small number of theophoric names.
Late attestations Inshushinak continued to be worshiped in
Neo-Elamite times. In one of the oldest texts possible to date to this period, (716–699 BCE) states that he reinstalled three statues representing deceased kings in the
kukkunum of Inshushinak. These included his father Huban-mena as well as two earlier rulers from the
Shutrukid dynasty, Hutelutush-Inshushinak and Šilhina-hamru-Lagamar. The goal of this act might have been to link his own rule with an earlier Elamite dynasty. The same ruler also apparently relocated a
kukunnum of Inshushinak from Susa to Karintaš, possibly to be identified with
Kerend-e Gharb on the road from
Baghdad and
Kermanshah, to protect it. A new temple dedicated to him was built in Susa by . A late administrative archive from Susa mentions the otherwise unattested phenomenon of local manifestations of Inshushinak, linked to Amperi, Halumirashi and Haran.
Heidemarie Koch argued that Inshushinak ceased to be worshiped after the emergence of the
Achaemenid state, but Wouter Henkelman points out in a more recent publication that while there is no source from Achaemenid Susa which would make it possible to evaluate whether he remained the main god of this city, based on parallels with the cults of
Napirisha and
Humban it is likely that he continued to be worshiped in the lowlands, and his cult might have enjoyed royal patronage. Yasmina Wicks notes that it is possible that Tepti-Huban-Inšušinak II, who might have reigned in the Achaemenid period as a vassal of
Cyrus II, mentions Inshushinak (as well as
Pinikir) in his inscriptions. , the last attested Neo-Elamite ruler, also invoked Inshushinak in an inscription meant to highlight his dedication to the god of Susa and to the city's population, though it has been noted he most likely reigned from elsewhere, possibly from a mountains part of modern
Khuzestan. ==Mesopotamian reception==
