The Religion of Babylonia and Assyria

Ur-Bau and Gudea alone of the ancient rulers refer to this god. The former erects a temple in honor of the god in some quarter of his capitol city, while the latter emphasizes the strength that the god has given him. These references, however, show that the god must have been of considerable importance, and in this case, his disappearance from the later pantheon is probably due to the absorption of his rôle by the greater god of Lagash,—Nin-girsu. Like Nin-girsu, Nin-si-a was a god of war, and his worship, imported perhaps from some ancient site to Lagash, falls into desuetude, as the attribute accorded to him becomes the distinguishing trait of the chief deity of the place.
