Before passing on, we have merely to note the very large part taken in both the old Babylonian and the Assyrian version by the struggle against Huwawa. The entire Yale tablet--forming, as we have seen, the third of the series--is taken up with the preparation for the struggle, and with the repeated warnings given to Gilgamesh against the dangerous undertaking. The fourth tablet must have recounted the struggle itself, and it is not improbable that this episode extended into the fifth tablet, since in the Assyrian version this is the case. The elaboration of the story is in itself an argument in favor of assuming some historical background for it--the recollection of the conquest of Amurru by some powerful warrior; and we have seen that this conquest must be ascribed to Enkidu and not to Gilgamesh. VIII. If, now, Enkidu is not only the older figure but the one who is the real hero of the most notable episode in the Gilgamesh Epic; if, furthermore, Enkidu is the Hercules who kills lions and dispatches the bull sent by an enraged goddess, what becomes of Gilgamesh? What is left for him? In the first place, he is definitely the conqueror of Erech. He builds the wall of Erech, [114] and we may assume that the designation of the city as _Uruk supûri_, "the walled Erech," [115] rests upon this tradition. He is also associated with the great temple Eanna, "the heavenly house," in Erech. To Gilgamesh belongs also the unenviable tradition of having exercised his rule in Erech so harshly that the people are impelled to implore Aruru to create a rival who may rid the district of the cruel tyrant, who is described as snatching sons and daughters from their families, and in other ways terrifying the population--an early example of "Schrecklichkeit." Tablets II to V inclusive of the Assyrian version being taken up with the Huwawa episode, modified with a view of bringing the two heroes together, we come at once to the sixth tablet, which tells the story of how the goddess Ishtar wooed Gilgamesh, and of the latter's rejection of her advances. This tale is distinctly a nature myth. The attempt of Gressmann [116] to find some historical background to the episode is a failure. The goddess Ishtar symbolizes the earth which woos the sun in the spring, but whose love is fatal, for after a few months the sun's power begins to wane. Gilgamesh, who in incantation hymns is invoked in terms which show that he was conceived as a sun-god, [117] recalls to the goddess how she changed her lovers into animals, like Circe of Greek mythology, and brought them to grief. Enraged at Gilgamesh's insult to her vanity, she flies to her father Anu and cries for revenge. At this point the episode of the creation of the bull is introduced, but if the analysis above given is correct it is Enkidu who is the hero in dispatching the bull, and we must assume that the sickness with which Gilgamesh is smitten is the punishment sent by Anu to avenge the insult to his daughter.
