What is the relationship between the king Gilgamesh and the wild man Enkidu? What, if anything, does this symbolize?

Enkidu is a wild man who becomes Gilgamesh's best friend. After being visited by Shamhat, the prostitute, Enkidu is civilized and leaves the animal world behind to journey with Shamhat to Uruk. Enkidu accompanies Gilgamesh to defeat Humbaba before he passes away. Gilgamesh journeys to the Underworld to try to bring Enkidu back to life. You could say that Enkidu is Gilgamesh's BFF. By the King, are you referring to Utnapishtim?
