In the Epic of Atrahasis, the man warned about the great flood is Atrahasis.
Atrahasis is the central human figure of an Old Babylonian flood story preserved on cuneiform tablets. The god Enki warns him about a coming catastrophe and instructs him to build a large boat, preserve life, and survive the flood. The name means something like “exceedingly wise.”
Atrahasis is related to other Mesopotamian flood traditions but is not the same character as Utnapishtim in the Epic of Gilgamesh or Ziusudra in the Sumerian King List and related stories. These figures occupy comparable roles in different literary traditions.
The Atrahasis story predates the surviving biblical manuscripts and is frequently studied in comparisons of ancient Near Eastern flood narratives. Similar themes do not make the names interchangeable.
