In the Epic of Gilgamesh, the flood survivor who builds a boat is called Utnapishtim.
Utnapishtim appears in the eleventh tablet of the Standard Babylonian Epic of Gilgamesh. The god Ea warns him that the gods intend to send a devastating flood, and Utnapishtim builds a large boat, takes aboard his family and living creatures, and survives the catastrophe. Afterward, he receives immortality.
The account is often compared with Noah’s Ark because both stories include a divine warning, a large vessel, preservation of life, birds used to test the waters, and a post-flood sacrifice. They are not the same narrative, however. Noah is the flood survivor in Genesis, while Utnapishtim is the corresponding figure in Gilgamesh. The Mesopotamian epic also names other characters and gods, including Gilgamesh, Enkidu, and Ea, whose roles differ from those in Genesis.
