Ancient Mesopotamian underworld

The ancient Mesopotamian underworld (known in Sumerian as Kur, Irkalla, Kukku, Arali, or Kigal, and in Akkadian as Erṣetu), was the lowermost part of the ancient near eastern cosmos, roughly parallel to the region known as Tartarus from early Greek cosmology. It was described as a dark, dreary cavern located deep below the ground, where inhabitants were believed to continue "a transpositional version of life on earth". The only food or drink was dry dust, but family members of the deceased would pour sacred mineral libations from the earth for them to drink. In the Sumerian underworld, it was initially believed that there was no final judgement of the deceased and the dead were neither punished nor rewarded for their deeds in life.

The ruler of the underworld was the goddess Ereshkigal, who lived in the palace Ganzir, sometimes used as a name for the underworld itself. Her husband was either Gugalanna, the "canal-inspector of Anu", or, especially in later stories, Nergal, the god of war. After the Akkadian Period (c. 2334–2154 BC), Nergal sometimes took over the role as ruler of the underworld. The seven gates of the underworld are guarded by a gatekeeper, who is named Neti in Sumerian. The god Namtar acts as Ereshkigal's sukkal, or divine attendant. The dying god Dumuzid spends half the year in the underworld, while, during the other half, his place is taken by his sister, the scribal goddess Geshtinanna, who records the names of the deceased.
