The Epic of Gilgamesh is an epic story from Babylonia and is among the earliest known literary works.
Scholars surmise that a series of Sumerian legends and poems about the mythological hero-king Gilgamesh, thought to be a ruler in the 3rd millennium BC, were gathered into a longer Akkadian poem.
The essential story revolves around the relationship between Gilgamesh, a king who has become distracted and disheartened by his rule, and a friend, Enkidu, who is half-wild and who undertakes dangerous quests with Gilgamesh.
This story is often credited by historians as being one of the first literary work with high emphasis on immortality.
