 Shamash helps Gilgamesh defeat Humbaba (the East Semitic name for Huwawa).Jeffrey H. Tigay suggests that Lugalbanda's association with the sun-god in the Old Babylonian version of the epic strengthened "the impression that at one point in the history of the tradition the sun-god was also invoked as an ancestor".In the Sumerian version, Gilgamesh's initial quest is to visit the Cedar Mountain and Humbaba is merely an obstacle that Gilgamesh and Enkidu encounter once they have already arrived there, but, in the Babylonian version, defeating Humbaba is the initial quest on which the heroes embark.
