Tablet IX, approximately line 10 talks about Sin. What document shows how Sin became the moon god, because this document does not?
Gilgamesh tells the monsters his story and his desire to see Utnapishtim. The Scorpion-man informs him that Utnapishtim lives on the other side of the mountain. To get there, Gilgamesh must use a passage that runs through the mountain. Shamash uses this same passage each night to travel back to the point where the sun rises every morning. Gilgamesh must travel the entire length of the passage in complete darkness. It will take him an entire day to do (Twelve “double-hours”). The Scorpion-man warns Gilgamesh that the way is treacherous and that no mortal has ever attempted it. Gilgamesh will be the first. He tells Gilgamesh that he must endure the tests of this long passage and lets him pass.
Gilgamesh walks through the mountain in absolute darkness. He cannot see in front of him or behind him. He walks the first, second, and third double hour in total blackness and struggles to breathe in the hot darkness. He walks four, five, and six double hours with the north wind blowing in his face. As the eleventh double hour approaches, the darkness begins to fade. At the end of the twelfth double hour, Gilgamesh emerges from the tunnel into the sunlight, breathing fresh air. He sees a beautiful garden filled with flowers of all colors. Beyond the garden, he sees the sea.
