former occasionally, the latter more frequently, there was no reason why a ruler should not at times be prompted to introduce an invocation to Bel, without the direct association with Anu and Ea. The confusion that thus ensues between the two Bels was not of serious moment, since from the context one could without difficulty determine which of the two was meant; and what we, with our limited knowledge of ancient Babylonia, are able to do, must have been an easy task for the Babylonians themselves.[154] It is tempting to suppose that the first command of the Decalogue (Exodus, xx) contains an implied reference to the Babylonian triad. Anu, Bel, and Ea. The theory of the triad succeeds in maintaining its hold upon Babylonian minds from a certain period on, through all political and intellectual vicissitudes. To invoke Anu, Bel, and Ea becomes a standing formula that the rulers of Babylonia as well as of Assyria are fond of employing. These three are the great gods _par excellence_. They occupy a place of their own. The kings do not feel as close to them as to Marduk, or to Ashur, or even to the sun-god, or to the moon-god. The invocation of the triad partakes more of a formal character, as though in giving to these three gods the first place, the writers felt that they were following an ancient precedent that had more of a theoretical than a practical value for their days. So among Assyrian rulers, Ashur-rish-ishi (_c._ 1150 B.C.) derives his right to the throne from the authority with which he is invested by the triad. Again, in the formal curses which the kings called down upon the destroyers of the inscriptions or statues that they set up, the appeal to Anu, Bel, and Ea is made. Ashurnasirbal calls upon the triad not to listen to the prayers of such as deface his monuments. Sargon has an interesting statement in one of his inscriptions, according to which the names of the months were fixed by Anu, Bel, and Ea. This 'archaeological' theory illustrates very well the extraneous position occupied by the triad. The months, as we shall see, are sacred, each to a different god. The gods thus distinguished are the ones that are directly concerned in the fortunes of the state,--Sin, Ashur, Ishtar, and the like. Anu, Bel, and Ea are not in the list, and the tradition, or rather the dogma according to which they assign the names is evidently an attempt to make good this omission by placing them, as it were, beyond the reach of the calendar. In short, so far as the historical texts are concerned which reflect the popular beliefs, the triad represents a theological doctrine rather than a living force. In combination, Anu, Bel, and Ea did not mean as much, nor the same thing, to a Babylonian or an Assyrian, as when he said Marduk, or Nabu, or Ashur, or Sin, as the case might be. It was different when addressing these gods individually, as was occasionally done. The Assyrians were rather fond of introducing Anu by himself in their prayers, and the
