One of the major elements of Gilgamesh is the friendship between Gilgamesh and Enkidu. They are closer than friends, almost acting as brothers. When Enkidu dies, Gilgamesh is inconsolable. Enkidu's death also reminds Gilgamesh that he too will soon be facing death. This thought terrifies him because during the time period of Gilgamesh, when one died, they simply ceased to exist. An afterlife did not exist. Gilgamesh wants to survive. He is concerned about his legacy and how to extend his influence on the world beyond his death. Love of life motivates Gilgamesh to seek out Utnapishtim to learn the secret of immortality.
