“We have only to glance over the titles which were given to Nebo to see how thoroughly the conception of “the prophet” was associated with that of ‘”the writer.”
He is not only “the wise,” “the intelligent,” “the creator of peace,” “the author of the oracle;” he is also “the creator of the written tablet,” “the maker of writing,” “the opener” and “enlarger of the ear.”
Assur-bani-pal is never weary of telling us, at the end of the documents his scribes had copied from their Babylonian originals, that “Nebo and Tasmit had given him broad ears (and) endowed (him) with seeing eyes,” so that he had “written, bound together and published the store of tablets, a work which none of the kings who had gone before had undertaken, even the secrets of Nebo, the list of characters as many as exist.”
In the literary dialect of the Semitic epoch, Nebo went by the Accadian name of dim-sar, “the scribe,” and the ideograph by which he is sometimes denoted was regarded by the Semitic literati as signifying “the maker of intelligence” and “the creator of writing.”
These, however, were not the only titles that Nebo bore. He was also “the bond of the universe,” and “the overseer of the angel-hosts of heaven and earth.” The latter office might be explained as derived from his duties as scribe of the gods; but it is hard to discover what connection there could be between the first title and his association with literature.
Light is thrown upon it, however, by the fact that the ziggurrat or tower of his temple at Borsippa had the name of “the house of the seven bonds of heaven and earth.” The seven “bonds” seem to represent the seven planets, or rather their stations; the tower was in seven stages, and each stage was painted so as to symbolise the colours symbolical of the several planets.
Nebo must, therefore, have once been an elemental god, or at all events a god connected with the chief of the heavenly bodies.
We know that Babylonian astronomy made him the presiding deity of the planet Mercury, just as it made Merodach the presiding deity of Jupiter; but it cannot have been in reference to this that the tower of his temple was dedicated to the seven heavenly spheres.
Nebo cannot well have been one of the seven himself in the conception of its builders; he must rather have been the universe in which the seven spheres were set.”
