Gilgamesh traveled through twelve leagues surrounded by total darkness before he emerged into the sunlight.
As Gilgamesh emerged into the garden of the sun he was greeted by Shamash.
No living man has passed this way, nor will again, and you will never find what you are looking for, while this world lasts, because the gods decreed that darkness be the end of mortal life.
Should I rest my head in the midst of earth and sleep for all the years when I have come so far? Should I stay here? I must go on. But let me see the sun, though I am as a dead man in this place, far from the land of living. Let me look, till I can look no longer, at its fire, for there is only darkness after death.
