Gilgamesh:
I looked for land in vain, but fourteen leagues distant there appeared a mountain, and there the boat grounded; on the mountain of Nisir the boat held fast, she held fast and did not budge. One day she held, and a second day on the mountain of Nisir she held fast and did not budge. A third day and a fourth day she held fast on the mountain and did not budge; a fifth day and a sixth day she held fast on the mountain. When the seventh day dawned I loosed a dove and let her go. She flew away, but finding no resting place she returned. Then I loosed a swallow, and she flew away but finding no resting place she returned. I loosed a raven, she saw that the waters retreated, she ate, she flew around, she cawed, but she did not come back. Then I threw everything open to the four winds, I made a sacrifice and poured a libation on the mountain top.The story refers back to the flooding of the Black Sea around some 7,000 BC. The Hebrews borrowed the story from the Sumerians.

I believe the account of Noah's flood as related in Ryan and Pittman's book, Noah's Flood. I read this book three times from the library, my son gave it to me as a Christmas present this year.
