The more pronounced superiority of the one place over the other finds expression in the relation of father to child, while that of master and servant emphasizes the complete control exercised by the one over the other.
Lastly, the absorption of one deity into another, is correlative either with the most perfect form of conquest, or the complete disappearance of the seat of his worship in consequence of the growing favor of one possessing sufficiently similar qualities to warrant identification with the other.
Lugal-banda.
Sin-gashid of the dynasty of Uruk makes mention of this deity at the beginning of one of his inscriptions.

To him and to his consort, Nin-gul, a temple as 'the seat of their joy' at that place is devoted.
This association of the god with the town points again to a local deity, but possessing a character which leads to the absorption of the god in the solar god, Nergal, whom we have already encountered, and who will occupy us a good deal when we come to the period after Hammurabi.

The identification of the two is already foreshadowed in an inscription of another member of the same dynasty, Sin-gamil, who places the name of Nergal exactly where his predecessor mentions Lugal-banda.

The first element in his name signifies 'king,' the second apparently 'strong,' so that in this respect, too, the god comes close to Nergal, whose name likewise indicates 'great lord.' The consort of Lugal-banda is Nin-gul.
Her name signifies 'the destructive lady,'-- an appropriate epithet for the consort of a solar deity.

It is Sin-gashid again who associates Ningul with Lugal-banda, and emphasizes his affection for the goddess by calling her his mother.
