Be this as it may, if our Nina has any connection with the goddess of Nineveh, it is certain that Ishtar has retained none of Nina's traits. The fusion in this case has been so complete that naught but the faintest tradition of an original and independent Nina has survived in the North. Anu. This god, who, from a theoretical point of view (as will be shown in a subsequent chapter), was regarded as standing at the head of the organized Babylonian pantheon, figures only incidentally in the inscriptions prior to the days of Hammurabi. Ur-Gur of the second dynasty of Ur, in invoking Nannar, calls the latter 'the powerful bull of Anu.' The reference is interesting, for it shows that already in these early days the position of Anu, as the god of the heavenly expanse, was fixed. The moon appearing in the heavens, and the resemblance of its crescent to a bull's horn,[74] are the two factors that account for the expressive epithet used by Ur-Bau. That the worship of the god of heaven _par excellence_ should not have enjoyed great popularity in the early days of the Babylonian religion might seem strange at first sight. A little reflection, however, will make this clear. A god of the heavens is an abstract conception, and while it is possible that even in an early age, such a conception may have arisen in some minds, it is not of a character calculated to take a popular hold. As we proceed in our attempt to trace the development of the Babylonian religion, we will find the line of demarcation separating the theological system, as evolved by the schoolmen, from the popular phases of the religion, becoming more marked. In the inscriptions of the old Babylonian rulers, comparatively little of the influence of the Babylonian theologians is to be detected. Even the description of the moon as the bull of heaven falls within the domain of popular fancy. It is different in the days after Hammurabi, when political concentration leads to the focussing of intellectual life in the Euphrates Valley, with all the consequences that the establishment of a central priesthood, with growing powers over ever-increasing territory, involves. It is to be noted, moreover, that the manner in which in the old Babylonian inscriptions _Anu_ is written,[75] indicates that the abstraction involved in the conception of a god of heaven had not yet been reached, though some measure of personification was of course inevitable at a time when animistic notions still held sway. A direct indication of this personification of heaven without the deification appears in the epithet 'child of Anu,' bestowed upon the goddess Bau. The reference to the heavens in this connection is an allusion to Bau's position as the patroness of that quarter of Lagash known as the 'brilliant town,'[76] and where Bau's temple stood. The transference of the quality of 'brilliancy' from the town to the goddess would be expressed by calling the latter the offspring of that part of visible
