Heh... This was a Jeopardy question (er, answer) on tonight’s show.
Is that why you posted this?
(Tonight’s reference to this king on Jeopardy was the first time I ever heard of him.)
The Epic of Gilgamesh is an epic poem about a king of Uruk and is one of the earliest surviving works of literature. What is posted, however, appears to be fantasy literature at least referring to Gilgamesh if not incorporating parts of the story.
