Ninurta (Nin Ur: God of War) in Sumerian and Akkadian mythology was the god of Lagash, identified with Ningirsu with whom he may always have been identical. In older transliteration the name is rendered Ninib and Ninip, and in early commentary he was sometimes portrayed as a solar deity.
In Nippur, Ninurta was worshiped as part of a triad of deities including his father, Enlil and his mother, Ninlil. In variant mythology, his mother is said to be the deity Ninhursag.
Ninurta often appears holding a bow and arrow, a sickle sword, or a mace named Sharur: Sharur is capable of speech in the Sumerian legend "Deeds and Exploits of Ninurta" and can take the form of a winged lion and may represent an archetype for the later Shedu.
In another legend, Ninurta battles a birdlike monster called Imdugud (Akkadian: Anzû); a Babylonian version relates how the monster Anzû steals the Tablets of Destiny which Enlil requires to maintain his rule. Ninurta slays each of the monsters later known as the "Slain Heroes" (the Warrior Dragon, the Palm Tree King, Lord Saman-ana, the Bison-beast, the Mermaid, the Seven-headed Snake, the Six-headed Wild Ram), and despoils them of valuable items (Gypsum, Strong Copper, the Magilum boat), and finally Anzû is killed by Ninurta who delivers the Tablet of Destiny to his father, Enlil. The Tablet of Destiny was what they believed to be what the universe's start was written on.
The consort of Ninurta was Ugallu in Nippur and Bau when he was called Ningirsu.
