The Epic of Gilgamesh, an epic poem from Mesopotamia, is amongst the earliest surviving works of literature, perhaps, the oldest written story on Earth. It tells the tail of the Hero King Gilgamesh, a demigod of superhuman strength who built the city walls of Uruk to defend his people from external threats, and travelled to meet the sage Utnapishtim, who had survived the Great Deluge. He is usually described as two-thirds god and one third man.
The story centers on a friendship between Gilgamesh and Enkidu. Enkidu is a wild man created by the gods as Gilgamesh’s equal to distract him from oppressing the people of Uruk. Together, they journey to the Cedar Mountain to defeat Humbaba, its monstrous guardian. Later they kill the Bull of Heaven, which the goddess Ishtar sends to punish Gilgamesh for spurning her advances. As a punishment for these actions, the gods sentence Enkidu to death.
The later half of the epic focuses on Gilgamesh’s distress at Enkidu’s death, and his quest for immortality. In order to learn the secret of eternal life, Gilgamesh undertakes a long and perilous journey to find the immortal flood hero, Utnapishtim. He learns that “The life that you are seeking you will never find. When the gods created man they allotted to him death, but life they retained in their own keeping.” His fame however lived on after his death, because of his great building projects, and his account of what Utnapishtim told him happened during the flood.
