In the Babylonian flood story Atrahasis, the human warned to build a boat is Atrahasis.
The Atrahasis Epic is an ancient Mesopotamian poem written in Akkadian. Its hero, Atrahasis, is warned by the god Enki that the gods intend to send a devastating flood. He is instructed to build a boat and preserve living creatures and his household. After the flood, Atrahasis offers a sacrifice.
The work is one of the important early flood traditions compared with the Genesis account. Both stories include a chosen survivor, a divinely sent flood, a boat, preservation of life, and a sacrifice afterward. Their settings, gods, motives, and details differ substantially.
The epic is known from cuneiform tablets dating to the second millennium BCE, although later copies also survive. Its survival helps scholars study how flood traditions circulated in ancient Mesopotamia.
