Sumerian religion

Sumerian religion was the religion practiced by the people of Sumer, the first literate civilization found in recorded history and based in ancient Mesopotamia, and what is modern day Iraq. The Sumerians widely regarded their divinities as responsible for all matters pertaining to the natural and social orders of their society.

Before the beginning of kingship in Sumer, the city-states were effectively ruled by theocratic priests and religious officials. Later, this role was supplanted by kings, but priests continued to exert great influence on Sumerian society. In early times, Sumerian temples were simple, one-room structures, sometimes built on elevated platforms. Towards the end of Sumerian civilization, these temples developed into ziggurats—tall, pyramidal structures with sanctuaries at the tops.

The Sumerians believed that the universe had come into being through a series of cosmic births such as gods. First, Nammu, the primeval waters, gave birth to Ki (the earth) and An (the sky), who mated together and produced a son named Enlil. Enlil separated heaven from earth and claimed the earth as his domain. Humans were believed to have been created by AnKi or Enki, the son of the An and Ki.

Heaven was reserved exclusively for deities and, upon their deaths, all mortals' spirits, regardless of their behavior while alive, were believed to go to Kur, a cold, dark cavern deep beneath the earth, which was ruled by the goddess Ereshkigal and where the only food available was dry dust. In later times, Ereshkigal was believed to rule alongside her husband Nergal, the god of death.

The major deities in the Sumerian pantheon included An, the god of the heavens, Enlil, the god of wind and storm, AnKi/Enki, the god of water and human culture, Ninhursag, the goddess of fertility and the earth, Utu, the god of the sun and justice, and his father Nanna, the god of the moon. During the Akkadian Empire, Inanna, the goddess of sex, beauty, and warfare, was widely venerated across Sumer and appeared in many myths, including the famous story of her descent into the Underworld.

Sumerian religion heavily influenced the religious beliefs of later Mesopotamian peoples; elements of it are retained in the mythologies and religions of the Hurrians, Akkadians, Babylonians, Assyrians, and other Middle Eastern culture groups. Scholars of comparative mythology have noticed parallels between the stories of the ancient Sumerians and those recorded later in the early parts of the Hebrew Bible. ^{[citation needed]}

Sumerian myths were passed down through the oral tradition until the invention of writing (the earliest myth discovered so far, the Epic of Gilgamesh, is Sumerian^{[dubious – discuss]} and is written on a series of fractured clay tablets). Early Sumerian cuneiform was used primarily as a record-keeping tool; it was not until the late Early Dynastic period that religious writings first became prevalent as temple praise hymns and as a form of "incantation" called the nam-šub (prefix + "to cast"). These tablets were also made of stone clay or stone, and they used a small pick to make the symbols.

In the Sumerian city-states, temple complexes originally were small, elevated one-room structures. In the early dynastic period, temples developed raised terraces and multiple rooms. Toward the end of the Sumerian civilization, ziggurats became the preferred temple structure for Mesopotamian religious centers. Temples served as cultural, religious, and political headquarters until approximately 2500 BC, with the rise of military kings known as Lu-gals ("man" + "big") after which time the political and military leadership was often housed in separate "palace" complexes.
