Discoveries of ruins under the Persian Gulf maybe of Dilmun . </P> <P> In the Mesopotamian epic poem Epic of Gilgamesh, Gilgamesh had to pass through Mount Mashu to reach Dilmun, Mount Mashu is usually identified with the whole of the parallel Lebanon and Anti-Lebanon ranges, with the narrow gap between these mountains constituting the tunnel . </P> <P> Dilmun, sometimes described as "the place where the sun rises" and "the Land of the Living", is the scene of some versions of the Sumerian creation myth, and the place where the deified Sumerian hero of the flood, Utnapishtim (Ziusudra), was taken by the gods to live forever .
