Sumerian Religion, Temples and Gods
In Sumer, the southern Mesopotamian region of present-day Iraq, people worshipped local gods in temples and supplied them with food, animals and ritual service. Most written evidence survives in cuneiform, a writing system made of wedge-shaped signs pressed into clay. The Early Dynastic period (about 2900–2350 BCE), Akkadian Empire (about 2334–2154 BCE) and Ur III kingdom (about 2112–2004 BCE) provide distinct settings for these practices.

Gods and their cities
Independent Sumerian cities built distinct cults around local gods. Nanna, the moon god, was worshipped at Ur; Inanna at Uruk; Enki at Eridu; and Ningirsu at Girsu in the state of Lagash. Nippur’s E-kur temple belonged to Enlil, whose authority in Sumerian compositions extended beyond one city.
The temple as a god’s household
Sumerian hymns describe the temple as the deity’s house, equipped with a shrine, dais (a raised platform), offering table and staff. A hymn to Nanna at Ur pictures the god receiving morning and evening meals in the E-kishnugal, the temple of Nanna and his consort Ningal. It describes ritual washing, purified oil and the divine attendant Kusu cleansing hands before food is set out. The poem turns temple service into the care of a divine household: preparation, purification, music and meals all express a god’s presence and rank.
Administrative tablets show how provisions could be routed to cults. A Sumerian account dated 2037 BCE from Puzrish-Dagan, modern Drehem in Iraq, records sheep and goats allocated for religious offerings alongside taxation and military supplies. Another Ur III tablet at the Metropolitan Museum records animal deliveries for a sowing-seed festival. Together, these records show animals entering religious service through documented allocation and delivery before the sanctuary rite.
Divine attendants, donors and royal builders
Gudea’s late-third-millennium account of building Ningirsu’s E-ninnu at Girsu assigns ritual duties to divine attendants. Nanshe sings, Nindub prepares incense, and Shul-shaga washes and brews. These named gods belong to the narrative of Ningirsu’s household, while administrative tablets separately record animals and other provisions delivered for cult use.
Gudea’s narrative makes the building itself a religious undertaking. After a dream in which Ningirsu commands the project, Gudea asks the goddess Nanshe to interpret it and performs an animal omen. The text then describes timber, copper, stone and other materials arriving from distant regions, before the ruler sets out the temple plan and lays its first brick in a public rite. When the E-ninnu is ready, Gudea presents food and drink and invites Ningirsu to enter. The sequence links divine command, interpretation, material work and dedication; the story also presents temple construction as proof of a ruler’s proper relationship with his god.
Stone donor statues offer another form of service. From Early Dynastic temples, including Nippur and sites along the Diyala River, come figures of worshippers with clasped hands and inscriptions naming a deity and donor. Museum curators interpret these images as an enduring presence before the god when the donor was absent. An inscribed statue of the Ur III king Shulgi names both the ruler and personnel of the estate of Nindara, a local god of Lagash. The object joins a ruler’s image to a particular temple institution and its deity.
Priestesses, kingship and written tradition
Royal families also held religious offices. Enheduanna, daughter of Sargon of Akkad, served as the en-priestess, a senior priestly office, of Nanna at Ur in the twenty-third century BCE. The office connected the ruling dynasty to one of the south’s most prominent sanctuaries. A disc excavated at Ur bears an inscription identifying her as Nanna’s priestess and Sargon’s daughter. The fragmentary inscription, preserved through a later Old Babylonian copy, says she dedicated the disk to an Inanna temple to commemorate the construction of a sacred dais. Compositions later associated with her include the Temple Hymns, a collection praising sanctuaries across many cities. Scholars debate whether she personally composed all the works assigned to her, so her historical office and the later literary attribution remain distinct evidence.
Sumerian compositions gave divine authority a place in political life. A hymn to Nanna says that An and Enlil established his lordship and seats the gods at a meal in his sanctuary. Enlil’s temple at Nippur was described as a place from which legitimate kingship was granted. At Ur, five inscribed cylinders were sealed beneath the pavement of a room in the temple of Nimintabba. Their inscriptions write Shulgi’s name with the sign used for divine names and call him ‘king of the four quarters’; archaeologist Richard L. Zettler dates them to the second half of Shulgi’s reign. This provides specific evidence of divine honors in Ur III royal cult.
Literary stories added movement and encounter to this sacred geography. In the Sumerian composition Enki’s Journey to Nibru, the god travels by boat from Eridu to Nippur, sacrifices oxen and sheep, and prepares a feast for Enlil. The Walters Art Museum’s tablet, dated about 1800–1600 BCE, preserves a Sumerian temple hymn in a later Old Babylonian copy, showing how scribes carried these compositions into a new period.
