After the death of his friend Gilgamesh can't stop thinking about his own death, so he gives up being king and sets out to find his ancestor Utnapishtim. Utnapishtim is the Mesopotamian version about Noah and after the flood the gods gave him eternal life. Gilgamesh's journey takes him to the double-peaked mountain called Mashu. Utnapishtim lives beyond the mountain, but the two scorpion monsters who guard the entrance refuse to let Gilgamesh enter the tunnel that passes through it. After hearing Gilgamesh's pleas, the scorpions let him pass. Upon reaching the end of the tunnel, Gilgamesh meets Siduri, a tavern keeper, and tells her of his quest. She warns him that seeking the inner life is futile and that he should be content with the pleasures of the world. When she accepts that she cannot dissuade him from his quest, she tells him where he can find a ferryman, Urshanabi. Urshanabi accompanies Gilgamesh on the boat journey across the sea and through the Waters of Death to Utnapishtim. Gilgamesh tries to convince Utnapishtim to allow him to live forever, so Utnapishtim gives him a test. Gilgamesh must stay awake for a week, but fails and is told to return home to Uruk. When Gilgamesh was about to leave Utnapishtim's wife he convinces him to tell Gilgamesh about a miraculous plant that restores youth. Gilgamesh finds the plant and takes it with him, but one night while they are there a serpent steals the plant
