A Pretext for Descent
In the Sumerian version of Inanna's descent to the underworld, she claims she is traveling below specifically to attend Gugalanna's funeral — a cover story for her true purpose of challenging Ereshkigal's rule. The name Gugalanna is also associated in some traditions with the monstrous Bull of Heaven that Inanna later unleashes against Gilgamesh in the Epic of Gilgamesh, though the two figures are not always treated as strictly identical across different texts.
Mesopotamian religion spans Sumerian, Akkadian, and Babylonian sources composed and recopied across nearly three thousand years, so names, genealogies, and even a deity's role often shift between traditions (Sumerian An/Enki/Inanna alongside their Akkadian/Babylonian forms Anu/Ea/Ishtar); the account above follows the most widely attested version, usually as consolidated in the Babylonian Enuma Elish or the standard Akkadian Epic of Gilgamesh.
