“The IVth tablet is concerned with a description of the monster with whom the heroes are about to do battle.
Khumbaba, whom Bel had appointed to guard the cedar (i.e., one particular cedar which appears to be of greater height and sanctity than the others), is a creature of most terrifying aspect, the very presence of whom in the forest makes those who enter it grow weak and impotent.
As the heroes draw near Eabani complains that his hands are feeble and his arms without strength, but Gilgamesh speaks words of encouragement to him. It may be noted, in passing, that the word Khumbaba is of Elamite origin, a fact which has led certain authorities to identify the monster with an Elamite dynasty which anciently dominated Erech, and which came to grief about 2250 BCE.
It is difficult, if not impossible, to establish the connexion between the mythical encounter and a definite historical event; but it may at least be presumed that the bestowal of an Elamite designation on the monster argues a certain enmity between Elam and Babylon.
The next fragments bring us into the Vth tablet.
The heroes, having reached “a verdant mountain,” paused to survey the Forest of Cedars. When they entered the forest the death of Khumbaba was foretold to one or other, or both of them, in a dream, and they hastened forward to the combat.
Unfortunately the text of the actual encounter has not been preserved, but we learn from the context that the heroes were successful in slaying Khumbaba.
