Nammu

In local Eridu theology Nammu is presented as a primeval mother figure who precedes the ordered cosmos and is responsible for the origination of gods and cosmic elements. She is mother of Enki/Ea in multiple texts and in some Old Babylonian god-lists and inscriptions is described as "mother who gave birth to heaven and earth" or "first mother who gave birth to all (or senior) gods." Theological traditions vary: the name is written with the logogram ENGUR (also used for the term engur/apsu, the primeval waters), yet textual evidence distinguishes the goddess from the body of water and in some texts she is even described as creator of the engur; other texts and later commentaries offer divergent etymologies and identifications, showing a fluidity of interpretation over time.

No consistent anthropomorphic or iconographic description of Nammu survives in the supplied material. Sources emphasize her genealogical and functional identity as a mother and as a watery primordial source rather than a fixed pictorial form. Scholarly discussion links her to watery domains (groundwater, the cosmic river, or primeval waters) and she bears epithets such as "lady who is great and high in the sea," but the evidence does not preserve a stable visual representation or a standard set of attributes.

Nammu's principal attested functions are creative and ritual. In mythic texts she participates in creation alongside deities such as Enki and Ninmah and is accorded motherly roles in theogony. In the ritual and incantation corpus she is invoked in apotropaic contexts: to purify and consecrate, and against demons, illness, and scorpions. Her presence in incantatory lists alongside other healing and ritual deities indicates that she remained an active figure within practical ritual practice rather than only a remote ancestral creator. The sources do not record independent feats of destruction or domination; her power is expressed through creative parentage and ritual efficacy as invoked by practitioners.
