Here's another: Utnapishtim, a figure from the Mesopotamian Epic of Gilgamesh - the hero Gilgamesh, after long and arduous travel, finds Utnapishtim living in the paradise of Dilmun at the end of the Earth, where he has been granted eternal life by the gods. (Gilgamesh's reason for seeking out Utnapishtim, incidentally, is to learn the secret of immortality - like Methuselah, he comes close to the gift but fails to achieve it). Utnapishtim then tells how he survived a great flood, and how he was afterwards granted immortality by the gods. The story has remarkable similarities with the account in Genesis.
Lamech's statement that Noah will be named "rest" because "out of the ground which the Lord has cursed this one shall bring us relief from our work and from the toil of our hands," has another faint parallel in Babylonian mythology: the gods grew tired of working, digging the channels of the rivers, and so the god Enki created man from clay and blood and spit to do the work for them. Enki fell in love with his creation, and later warned Utnapishtim that the other gods planned to send a flood to destroy all life, and advised him on how to construct his ark.
