In the Epic of Gilgamesh, the flood survivor who built a vessel is called Utnapishtim.
Utnapishtim appears in the flood story embedded in the Babylonian Epic of Gilgamesh. The god Ea warns him that the gods intend to send a devastating flood and instructs him to build a large boat. Utnapishtim brings aboard his family, craftsmen, animals, and other living things, then survives the disaster.
After the waters recede, Utnapishtim releases birds to test whether land has emerged, a detail often compared with the raven and dove sequence in Genesis. He eventually makes an offering, and the god Enlil grants him and his wife a special form of immortality.
Utnapishtim is not Noah under another spelling. He is the flood hero of a different Mesopotamian literary tradition, although the two narratives share important motifs. The Epic of Gilgamesh version is preserved in cuneiform tablets, especially the eleventh tablet of the standard Babylonian edition.
