Ninazu's primary cult center was
Enegi, a city located between
Ur and
Uruk. The association is first attested in an
Early Dynastic document from
Lagash. His main temple in that city was Egidda, "sealed house" or "storehouse". Offerings made to him in his cult center are mentioned in tablets from
Puzrish-Dagan. Much like Ninazu himself, Enegi was associated with the underworld, and could be described as "pipe of Ereshkigal's quay" in literary texts in reference to a type of implement used in
funerary libations. The
cults of Enegi were likely influenced by
Uruk, as in addition to Ninazu, typical Urukean deities like the messenger goddess
Ninshubur, the demigod
Gilgamesh and his mother
Ninsun were venerated in this city. A second cult center of Ninazu was
Eshnunna, where his temple was the Esikil, "pure house". Frans Wiggermann maintains that the Ninazu of Eshnunna was identical with the Ninazu of Enegi. However, according to Irene Sibbing-Plantholt, it is uncertain if the latter was indeed identical, and thus a southern deity imported to a northern city, a different deity sharing the same name, or an
epithet of a separate deity identical with the name of the god of Enegi. Starting in the
Akkadian period, Ninazu apparently competed with the god
Tishpak in Eshnunna, and ceased to be mentioned in documents from it altogether after
Hammurabi's conquest. It is usually presumed that the later had foreign origin, and he might have been introduced to this city as early as in the late fourth and early third millennium BCE. While similar in character, Ninazu and Tishpak were not fully conflated, and unlike
Inanna and Ishtar or
Enki and Ea were kept apart in god lists. In Lagash, Ninazu was one of the deities who were part of the official pantheon during the reign of
Urukagina, but he is otherwise not attested there in the Early Dynastic period, with the exception of some theophoric personal names. Later
Gudea built a temple dedicated to him, but its precise location and ceremonial name are not known. From Enegi, Ninazu was also introduced to Ur, where his cult survived until late periods. A temple dedicated to him in this city was also named Egidda, and it has been proposed that it might have been where the center of his cult was relocated after the decline of Enegi suggested by its absence from records from the first millennium BCE. Other cities from which offerings to him are attested are
Nippur,
Umma and
Adab. In the first millennium BCE, he was also venerated in
Assur. Furthermore, the name of a temple dedicated to him, Ekurmaḫ, "house, exalted mountain," is known from the
Epic of Anzû, but its location is unknown. The last available evidence for cult of Ninazu are theophoric personal names from Ur invoking him, present in sources from the period of
Persian rule over Mesopotamia. According to
Paul-Alain Beaulieu, he must have remained a relatively popular deity in Ur. A peculiarity associated with the late worship of Ninazu in Ur is the use of both the basic form of his name and its
Emesal equivalent, Umunazu, in personal names, with the latter being slightly more common - 25 names with Ninazu and 30 with Umunazu are presently known. It is possible that this situation was influenced by the role played by
lamentation priests, who traditionally memorized texts written in the Emesal dialect, in the survival of Ninazu's cult. Other underworld deities, like his son Ningishzida, the deified snake Nirah and the incantation goddess
Ningirima, also retained a degree of popularity, likely due to being envisioned as members of Ninazu's court. ==References==
