In historical texts she plays scarcely any role at all, but in incantations she is often referred to; and from the fact that Nisaba is appealed to, to break the power of the demons in conjunction with Ea, it would appear that the position once occupied by her was no insignificant one.
Nin-girsu, it will be recalled, has also traits which connect him with agricultural life, and Nina being the daughter of Nin-si-a, one of the forms under which Ningirsu-Ninib appears, we may connect Nisaba directly with the cults of which Lagash formed the center.

Nisaba must have been the consort of one of the agricultural gods, whose jurisdiction falls within Gudea's empire.

Lugal-zaggisi, as the king of Uruk, assigns to the goddess a first place.

Her origin must, therefore, be sought in this region.

In later days the name of the goddess is used to describe the fertility of the soil in general.
