The worship of Iyarri is best attested from cities from central
Anatolia and from areas inhabited by
Luwians. Piotr Taracha considers him a god of Luwian origin, though one who was also incorporated into many local
Hittite pantheons. Since he is absent from sources showing
Hurrian influence, it is assumed that even if his origin was foreign, he did not reach Anatolia through Hurrian mediation. According to Taracha, while it is impossible to speak of a uniform Luwian pantheon, Iyarri can nonetheless be considered one of the best attested deities worshiped by Luwians, comparable in importance to
Tarḫunz,
Tiwad,
Arma,
Maliya, Šanta or
Kamrušepa. He is attested for example in texts pertaining to the local pantheon of the western city of Ištanuwa. A temple of Iyarri existed in a city known as Ḫarrana or Ḫarranašši, as indicated by the document CTH 260, which states that king
Arnuwanda I desposted tablets inscribed with oaths of officials from Kinnara there. Another temple dedicated to the same god was located in Guršamašša. A festival focused on him which took place in this city involved a ritual reenactment of a battle between the armies of Hatti and the "men of Maša". Iyarri was commonly invoked in oaths, for example in various Hittite treaties. In Ura, people had to drink from a
rhyton dedicated to him when taking an oath involving him, while an instructive text from the reign of
Tudḫaliya IV, KUB 26.24+, mentions the preparation of three copies of a bronze oath tablet which had to be presented to Iyarri in
Hattusa,
Arinna and Ḫartana. In a ritual associated with the last of these cities, KUB 38.32, he is one of the three main deities next to the deified mountain Ziwana and a local weather god associated with the same landmark. Attested
theophoric names invoking Iyarri, examples of which include Iyarra-muwa, Iyarra-piya, Iyarra-zalma and Iyarra-ziti, exclusively combine this theonym with elements from
Anatolian languages, though Alfonso Archi notes this does not necessarily rule out an origin in another area, as linguistically Anatolian names invoking deities such as
Šauška or
Ḫepat are also known, and reflect the fact that these deities were integrated into local culture rather than their origin. It is possible that eventually Iyarri was eventually superseded by Šanta, as the latter appears much more commonly in sources from the first millennium BCE. There is little, if any, evidence for the worship of the former continuing after the fall of the
Hittite Empire, and he is entirely absent from later
hieroglyphic Luwian texts, with the only exception being two possible theophoric names,
Yariris (regent of
Carchemish in late ninth of early eighth century BCE) and n Iyara/isa/i (attested on an eighth century BCE artifact from Kululu). However, no examples of the latter are known from later
Greco-Roman sources, and while a connection between names with the element
Iya- and Iyarri has been proposed, they might also be related to deities such as
Iyaya or
Iya (derived from Mesopotamian
Ea) instead. ==References==
