The Sumerians envisioned the universe as a closed dome surrounded by a primordial saltwater sea. Underneath the terrestrial earth, which formed the base of the dome, existed an underworld and a freshwater ocean called the
Abzu. The deity of the dome-shaped
firmament was named
An; that of the earth was named
Ki. First the underground world was believed to be an extension of the goddess Ki, but later developed into the concept of
Kur. The primordial saltwater sea was named
Nammu, who became known as
Tiamat during and after the
Ur III period. Some ancient Sumerians believed that salt and other minerals were alive, and could even think independent thoughts.
Creation story The main source of information about Sumerian creation mythology is the prologue to the epic poem
Gilgamesh, Enkidu, and the Netherworld, and a place where
holy stars resided. Each dome was made of a different kind of precious stone. The middle dome of heaven was made of
saggilmut stone and was the abode of the
Igigi. Instead, after a person died, his or her soul went to
Kur (later known as
Irkalla), a dark shadowy
underworld, located deep below the surface of the earth.

Sumerian afterlife was a dark, dreary cavern located deep below the ground, where inhabitants were believed to continue "a shadowy version of life on earth". This bleak domain was known as
Kur, and was believed to be ruled by the goddess
Ereshkigal. All souls went to the same afterlife, and a person's actions during life had no effect on how the person would be treated in the world to come. The souls in
Kur were believed to eat nothing but dry
dust and family members of the deceased would ritually pour
libations into the dead person's grave through a clay pipe, thereby allowing the dead to drink. Nonetheless, there are assumptions according to which treasures in wealthy graves had been intended as offerings for
Utu and the
Anunnaki, so that the deceased would receive special favors in the underworld. During the
Third Dynasty of Ur, it was believed that a person's treatment in the afterlife depended on how he or she was buried; those that had been given sumptuous burials would be treated well, but those who had been given poor burials would fare poorly, and were believed to haunt the living. The entrance to Kur was believed to be located in the
Zagros Mountains in the far east. It had seven gates, through which a soul needed to pass. The god
Neti was the gatekeeper. Ereshkigal's
sukkal, or messenger, was the god
Namtar.
Galla were a class of demons that were believed to reside in the underworld; their primary purpose appears to have been to drag unfortunate mortals back to Kur. They are frequently referenced in magical texts, and some texts describe them as being seven in number. Several extant poems describe the
galla dragging the god
Dumuzid into the underworld. The later Mesopotamians knew this underworld by its
East Semitic name:
Irkalla. During the
Akkadian Period, Ereshkigal's role as the ruler of the underworld was assigned to
Nergal, the god of death. The Akkadians attempted to harmonize this dual rulership of the underworld by making Nergal Ereshkigal's husband. ==Pantheon==
