is the goddess Bau. Gula was the goddess of healing and medicine and she was sometimes alternately said to be the wife of the god Pabilsaĝ or the minor vegetation god Abu. Bau was worshipped "almost exclusively in Lagash" and was sometimes alternately identified as the wife of the god Zababa. She and Ninĝirsu were believed to have two sons: the gods Ig-alima and Šul-šagana. Bau also had seven daughters, but Ninĝirsu was not claimed to be their father. As the son of Enlil, Ninurta's siblings include: Nanna, Nergal, Ninazu, Enbilulu, and sometimes Inanna. Mythology Lugal-e Second only to the goddess Inanna, Ninurta probably appears in more myths than any other Mesopotamian deity. In the Sumerian poem Lugal-e, also known as Ninurta's Exploits, a demon known as Asag has been causing sickness and poisoning the rivers. Ninurta confronts Asag, who is protected by an army of stone warriors. Ninurta slays Asag and his armies. Then Ninurta organizes the world, using the stones from the warriors he has defeated to build the mountains, which he designs so that the streams, lakes and rivers all flow into the Tigris and Euphrates rivers, making them useful for irrigation and agriculture. Ninurta's mother Ninmah descends from Heaven to congratulate her son on his victory. Ninurta dedicates the mountain of stone to her and renames her Ninhursag, meaning "Lady of the Mountain". Finally, Ninurta returns home to Nippur, where he is celebrated as a hero. This myth combines Ninurta's role as a warrior deity with his role as an agricultural deity. The title Lugal-e means "O king!" and comes from the poem opening phrase in the original Sumerian. Ninurta's Exploits is a modern title assigned to it by scholars. The poem was eventually translated into Akkadian after Sumerian became regarded as too difficult to understand. A companion work to the Lugal-e is Angim dimma, or Ninurta's Return to Nippur, which describes Ninurta's return to Nippur after slaying Asag. It contains little narrative and is mostly a praise piece, describing Ninurta in larger-than-life terms and comparing him to the god An. Angim dimma is believed to have originally been written in Sumerian during the Third Dynasty of Ur ( 2112 – 2004 BC) or the early Old Babylonian Period ( 1830 – 1531 BC), but the oldest surviving texts of it date to Old Babylonian Period. Numerous later versions of the text have also survived. It
