The gods were angry at mankind so they sent a flood to destroy him. The god Ea, warned Utnapishtim and instructed him to build an enormous boat to save himself, his family, and "the seed of all living things." He does so, and the gods brought rain which caused the water to rise for many days. When the rains subsided, the boat landed on a mountain, and Utnapishtim set loose first a dove, then a swallow, and finally a raven, which found land. The god Ishtar, created the rainbow and placed it in the sky, as a reminder to the gods and a pledge to mankind that there would be no more floods.
