In the Sumerian flood story, the survivor warned by the god Enki is Ziusudra.
Ziusudra is the central human figure in the Sumerian Flood Story, preserved on a fragmentary tablet from the late third millennium BCE. The gods decide to send a devastating flood, but Enki communicates the warning to Ziusudra, who builds a large boat and survives with living creatures and essential provisions.
After the waters recede, Ziusudra offers a sacrifice and is granted an exceptionally long or immortal life in the surviving tradition. His story is earlier than the Standard Babylonian Epic of Gilgamesh and is one of several ancient Mesopotamian flood narratives connected by shared themes.
Ziusudra is sometimes confused with Atrahasis or Utnapishtim. Those names belong to related flood traditions in Akkadian literature and the Gilgamesh epic, whereas Ziusudra is the Sumerian name.
