through all times to enjoy great popularity at Babylon, was at Eridu, which, we know, once lay on the Persian Gulf, but does so no longer. The similarity of the epithets bestowed in various texts upon Ea and Nabu point most decidedly to a similar starting-point for both; and since in a syllabary[127] we find the god actually identified with a deity of Dilmun,--probably one of the islands near Bahrein,--there are grounds for assuming that a tradition survived among the schoolmen, which brought Nabu into some connection with the Persian Gulf. Sayce[128] has already suggested that Borsippa may have originally stood on an inlet of the Persian Gulf. Nabu is inferior to Ea, and were it not for the priority of Marduk, he would have become in Babylonian theology, the son of Ea. Since this distinction[129] is given to Marduk, no direct indication of an original relationship to Ea has survived. But besides being the god of wisdom and intelligence, Nabu is a patron of agriculture, who causes the grain to sprout forth. In religious and historical texts, he is lauded as the deity who opens up the subterranean sources in order to irrigate the fields. He heaps up the grain in the storehouses, and on the other hand, the withdrawal of his favor is followed by famine and distress. Jensen[130] would conclude from this that he was originally (like Marduk, therefore) a solar deity. This, however, is hardly justified, since it is just as reasonable to deduce his role as the producer of fertility from his powers as lord of some body of water. However this may be, in the case of Nabu, there are no grounds for supposing that he represents the combination of two originally distinct deities. A later--chiefly theoretical--amalgamation of Nabu with a god Nusku will be discussed in a subsequent chapter.[131] Hammurabi and his immediate successors, it is noteworthy, do not make mention of Nabu. A sufficient number of inscriptions of this period exists to make it probable that this omission is not accidental. This dynasty was chiefly concerned in firmly establishing the position of Marduk. Other deities could, indeed, be tolerated at his side, provided they were subservient to him; but Nabu, the god of a place so near Babylon, might prove a dangerous rival because of this proximity. The city on the west bank of the Euphrates was probably as old as that on the east, if not, indeed, older. It did not seem consistent with this devotion to Marduk that Hammurabi and his successors should also recognize Nabu. Policy dictated that Nabu should be ignored, that the attempt must be made to replace his worship, even in Borsippa, by that of Marduk. Viewed in this light, Hammurabi's establishment of the Marduk cult in Borsippa assumes a peculiar significance. It meant that Borsippa was to be incorporated as part of Babylon, and that Marduk was henceforth to take the place occupied by Nabu. In order to emphasize this, Hammurabi actually transfers the name of Nabu's temple in
