For the present, it is sufficient to note that the systematization of popular beliefs, involved in the distinctions thus emphasized in the groupings of deities into classes, begins at so early a period.

This systematization, however, has not yet assumed final shape.

True, the moon-god has already been given the place, immediately following upon the triad, that he will hold in the developed form of Babylonian theology; but while, as we have seen, Sin properly takes precedence of the sun-god, the latter should follow in the wake of his associate.

Not only, however, does Nin-girsu precede, but two other deities who are closely related in general character to the 'warrior deity' of Gudea's dominion.

Then, the two great goddesses, Bau and Ninni, are introduced, and it is not until they are disposed of that the sun-god, together again with Pa-sag as a kind of lieutenant,[111] is invoked.
