Inanna was the foremost Sumerian goddess, patron deity of Uruk. Her name was written with a sign that represents a reed stalk tied into a loop at the top. This appears in the very earliest written texts from the mid-fourth millenium B.C. She is also mentioned in all the early god lists among the four main deities, along with Anu, Enki, and Enlil. In the royal inscriptions of the early Dynastic Period, Inanna is often invoked as the special protectress of kings. Sargon of Akkad claimed her support in battle and politics. It appears that it was during the third millenium that the goddess acquired martial aspects that may derive from a syncretism with the Semitic deity Ishtar. Inanna's main sanctuary was the Eanna (`House of Heaven') at Uruk, although she had temples or chapels in most cities (89).
