Irkalla
Mythic, worshipped by the Akkadians of Sumer (modern-day Iraq), circa 2350–2150 B.C.E.
Irkalla is the Babylonian name for the underworld as well as another name for its ruler, Ereshkigal. In the Mesopotamian Epic of Gilgamesh, the hero’s companion Enkidu is led to the “palace of Irkalla, Queen of Darkness, to the house from which none who enters ever returns, down the road from which there is no coming back.”
