In the Epic of Gilgamesh, the flood survivor who builds the giant boat is named Utnapishtim.
Utnapishtim appears in the epic’s flood story, especially in Tablet XI of the standard version. The god Ea warns him of a coming flood and instructs him to build a boat, preserve life, and bring aboard living creatures and craftsmen. After the flood, Utnapishtim offers a sacrifice and receives extraordinary life from the gods.
The episode is often compared with the Genesis account of Noah because both include a divinely warned flood, a large vessel, preserved life, birds, and a sacrifice. They are not the same character under different spellings: Noah belongs to the Hebrew Bible, while Utnapishtim belongs to Mesopotamian literature.
Some translations use variant forms such as Utanapishtim. “Utnapishtim” is the standard English form used for the character in many modern references.
